Dahua Training Course Notes What is covered Module 1 - Introduction to HD-CVI & IP What is HD-CVI? Module 1 - Introduction to HD-CVI HD-CVI is an analogue HD technology by Dahua that delivers HD images using standard analogue installation methods. HD-CVI cameras output an analogue video signal at a higher frequency than that of standard definition analogue cameras. Using this technology HD images can be transmitted using coaxial or twisted pair cable. Additional signals such as Audio, Alarms and PTZ Telemtry are also transmitted down the same cable. Module 2 - Specifying and Installation Module 3 - HD-CVI Camera Configuration Module 4 - IP Camera Installation & Configuration Module 5 - NVR Installation & Configuration Module 6 - Software HD-CVI Benefits Many of the benefits that come with HD-CVI systems include: HD images up to 1080P Video, Audio & Data via a single cable A wide range of remote access features Same or lower cost as standard analogue systems HD-CVI Video HD-CVI video has many of the same abilities as standard analogue video signals. Video transmission up to 300m (720P) Video transmission up to 200m (1080P) Compatible with many analogue accessories including passive baluns Signals can be boosted using analogue amplifiers HD-CVI Audio Every HD-CVI system includes support for audio recording, there are multiple options available for connecting microphones such as camera models with audio inputs or DVRs with audio inputs. Every HD-CVI DVR model also supports talkback audio and is equipped with a single audio input and output for this purpose. Transmission distances are the same as HD-CVI video. HD-CVI Telemetry HD-CVI provides telemetry control with very little configuration, as PTZ Telemetry is transmitted via the BNC of the DVR, protocol and ID programming is not required. PTZ control via video cable No telemetry configuration required Camera alarm inputs signal DVR via video cable Motorised lens control via video cable Camera OSD control via video cable 2 3
Module 1 - Introduction to HD-CVI Module 1 - Introduction to IP HD-CVI Cable Multiple cable types are supported when using HD-CVI including both coaxial and twisted pair. Transmission distances vary between cables but all distances referenced by Cop Security are based on RG59 or Cat5e unless specified. Cable types supported by HD- CVI are: Devices on a network are managed by the use of a unique identifier known as an IP address. An IP address enables devices to communicate with each other across a network. Every device on a network must have an IP address in order to communicate correctly. RG59, CT100, RG6 Cat5e, Cat6 300m transmission range for both RG59 & Cat5e Boost transmission range using video amplifiers Where to install HD-CVI IP Address: 10.1.1.101 IP Address: 10.1.1.102 IP Address: 10.1.1.103 IP Address: 10.1.1.104 HD-CVI is ideal for both new and existing installations, each camera is connected using BNC connectors, just like standard analogue. Existing analogue installations New coax or UTP installations Standard analogue camera support on every HD-CVI DVR Standard analogue output on cameras (specific models) IP Address: 10.1.1.1 Module 1 - Introduction to IP WHAT IS IP? Internet Protocol or simply IP is the communication method used by networked devices to communicate and transfer data between one another. All networked devices such as Computers, Phones, CCTV systems and other devices use the Internet Protocol to communicate. Transmission Control Protocol/Internet Protocol or TCP/IP is the protocol suite which includes the internet protocol. TCP/IP is the basic protocol used by the vast majority of devices communicating across local networks and the internet. The most common connection method used today is that of Ethernet, Ethernet cables are used to connect the devices together via Switches & Routers. WHAT ARE THE ADVANTAGES OF IP? Video, Audio, I/O Commands and Power can be transmitted through one cable. Plug and Play installation Connect devices indirectly HD and UHD Image Quality Manage cameras via PC or Laptop IP TRANSMISSION DISTANCE 100m for POE and Non POE Devices Can easily be extended using POE and Non POE repeaters Can also be extended using Switches and Fibre Radio transmission up to 15Km IP CCTV systems differ from analogue, HDCVI and other coax based systems in that every aspect of the system is network based. Every Camera and NVR communicate with each other the same way as any other IP based piece of equipment, such as a PC, Laptop or Mobile phone. The Video, Audio and Telemetry signals are converted into digital signals, consisting of data packets. These packets are then Streamed to the NVR via the network connection. Video Audio Data Packet WHAT IS PoE? Power over Ethernet (PoE) transmits data and provides power down the same cable to a network PoE device. By utilising PoE the number of cables required to install an IP CCTV system are minimalised. Each camera can be added to the system using just one cable. POE has a maximum transmission distance of 100m POE One cable Plug and Play (POE Camera > POE NVR) POE NVRs do not require additional switches PoE NVRs v Non-PoE NVRs Non-POE Requires POE switch/injector or separate power supply Manual configuration Non POE NVRs require network switches (POE or Non POE) PoE NVR & PoE Cameras Non-PoE NVR & PoE Cameras The process of converting video & audio into a digital signal is referred to as Encoding, often when adjusting video settings such as resolution or frame rate, the settings will be found in the Encode menu. When the digital signal is received by an NVR, PC or other device, the process of converting the signal and displaying it to the operator is called Decoding. P POE switch 5
Module 1 - Introduction to IP Module 2 - Specifying and Installation WHAT IS ONVIF? 32 CHANNEL NVR ONVIF is an open protocol incorporated throughout the IP CCTV industry, it is used to ensure interoperability between devices regardless of the manufacturer. An NVR that supports the ONVIF protocol will likely work with any IP camera that also utilises the protocol. Although ONVIF ensures compatibility between devices, it does not guarantee nor necessarily support all functions available on an IP camera or NVR. At the very least the ability for the NVR to decode the video stream of the camera is usually supported. Other functions such as PTZ Control, Motion Detection or Image settings are usually dependent on the specific IP camera manufacturer or model. Router 1Gbps Uplink 100Mbps POE LAN Connection Module 2 - Specifying and Installation 32 Channel NVR WHERE TO INSTALL IP 64 CHANNEL NVR New installations Existing Cat5e/Cat6 installations Network dependent installations Installations where HD or 4K/UHD images are required HD installations requiring wireless transmission 1Gbps Uplink 100Mbps POE LAN Connection CABLE DISTANCE & INFRASTRUCTURE The design of an IP CCTV system is probably the most important aspect of consideration. Items that should be considered include, PoE or Non PoE, Transmission Range and Connection methods. Router Wired 100m Cat5e/6 RG59 64 Channel NVR 100m 100m 128 CHANNEL NVR POE 300m No POE 500m Wireless transmission can be used when cabling is not possible, Ligowave units can transmit up to 15Km (point to point) or 10Km (point to multipoint). When using wireless transmission it is also important to check for obstructions that may interfere with the transmission, line of sight is required when using Ligowave units. 1Gbps Uplink CAMERA NETWORK DESIGN 100Mbps POE LAN Connection All Non POE NVRs do not support Plug and Play configuration, each camera is manually configured and then added to the system. Dahua Non POE units are available in 32, 64, 128 and 256 channel variants. Each NVR has a minimum of 2x 1Gbps network ports, one of the NVR Ethernet ports is used for the camera network, with the other Ethernet port used for the LAN network. When specifying a large IP system, it is important to take into account the amount of bandwidth being transmitted between the network switches and the NVR. Most POE switches offer multiple 1Gbps network ports along with multiple 100Mbps POE ports. In this scenerio, the 1Gbps network ports are used to connect the NVR to the switch and for connecting switch to switch. The 100Mbps are then used for the individual camera connections. Examples of this configuration can be seen on the next page. Router 128 Channel NVR 7
Module 2 - Specifying and Installation Module 2 - Specifying and Installation BANDWIDTH REQUIREMENTS Bandwidth requirements and limitations should always be considered when specifying an IP CCTV system. POE NVR Installations do not usually reach the limit of the NVR, whereas this is often possible on non PoE units. To put the bandwidth requirements for remote viewing into practice, you must first look at the encode settings of the cameras. The bitrate of an individual camera may already be higher than that of the internet connection The total bitrate of the system may be vastly higher than that of the internet connection Sub Stream is often the recommended stream for remote viewing NVR Bandwidth 56Mbps Total Camera Bandwidth 32Mbps IMAGE QUALITY There are three main items that make up an IP CCTV video stream; Resolution, Frame Rate and Bit Rate Resolution The pixel size of the image such as 1.3MP Frame Rate The number of images per second, real time video is 25 Bit Rate The overall size of the image in Kbps, the larger the bit rate the more bandwidth the video stream will use WHAT IS A MEGAPIXEL? Individual pixels make up any digital image such as photos or video. A megapixel (MP) is a million pixels, the resolution of digital cameras including IP CCTV cameras are measured in megapixels. To calculate how many megapixels a specific resolution is, multiply the resolution width and height together.. Large IP systems such as 32, 64, 128 & 256 channel are connected via switches and can easily reach the maximum bandwidth supported by the NVR. Reducing the bitrate on each camera is often required to provide the maximum number of channels supported on the NVR. 720P 1.3MP 1080P 1280x720 = 921600 pixels or just under 1.0MP 1280x960 = 1228800 pixels (1.3MP) 1920x1080 = 2073600 pixels (2.0MP) 16x Cameras 1080P, Real Time 16x Cameras 1080P, Real Time Sometimes the overall pixel size is rounded up to the nearest million or decimal place, such as 720P (1MP) & 1.3MP. 100Mbps Link 100Mbps Link Frame Rate 32 Channel NVR 256Mbps Incoming Bandwidth Network Switch 16x Cameras 1080P, Real Time 6Mbps 100Mbps Link Network Switch NVR Bandwidth 256Mbps Total Camera Bandwidth 256Mbps 16x Cameras 1080P, Real Time 6Mbps 100Mbps Link The frame rate of the video stream sets how many frames (still images) are captured per second, the higher the frame rate the smoother the video stream. Common frame rate settings that are used are 25 (Real Time), 12 (Half Real Time) and 6 (Quarter Real Time). In many situations, real time video is not required and so the frame rate can be configured to a lower settings such as Half or Quarter real time. An important aspect to consider when setting the frame rate, is the requirement of whether high detail items may be required such as License plates or Facial recognition. As an example, when capturing license plates it is often best to have the frame rate at a minimum of half real time. This is to ensure that at the moment of the target vehicle being in the optimum position to capture the license plate information, a frame is captured. If the camera is set for a low frame rate then a frame may not be taken at this optimum position. Bit Rate 32 Channel NVR 256Mbps Incoming Bandwidth Network Switch Network Switch NVR Bandwidth 256Mbps Total Camera Bandwidth 192Mbps When planning to make an IP system available for remote access across the internet, knowing the bandwidth capabilities of the on site internet connection is also very important Upload Speed Send speed of the internet connection Download Speed Receive speed of the internet connection Bit rate is the term used to describe the size of the video stream in Kbps (Kilo bits per second) or Mbps (Mega bits per second). When choosing the bit rate setting it is important to take into consideration both the Resolution and Frame rate. A high resolution and high frame rate will require a high bit rate to produce good quality video. If the bit rate is set too low, then the video will become pixilated and suffer from artefacts, especially during scene changes such as PTZ and object movement. A lower resolution and frame rate will require a lower frame rate, setting the bit rate higher than it needs to be will not give much advantage over video quality. Bit Rate Examples Resolution Frame Rate Required Quality Bit Rate 1.3MP 25 High 6144Kbps (6Mbps) 1.3MP 25 Good 4096Kbps (4Mbps) 1.3MP 12 High 3072Kbps (3Mbps) 1.3MP 12 Good 2048Kbps (2Mbps) 1080P 25 High 8192Kbps () 1080P 25 Good 6144Kbps (4Mbps) 1080P 12 High 4096Kbps (4Mbps) 1080P 12 Good 3072Kbps (3Mbps) 3MP 25 High 10240Kbps (10Mbps) 3MP 25 Good 8192Kbps () 3MP 12 High 5120Kbps (5Mbps) 3MP 12 Good 4096Kbps (4Mbps) 9
Module 2 - Specifying and Installation Bit Rate Type There are two types of bit rate to consider when configuring the encode settings of an IP camera, CBR and VBR. Constant Bit Rate (CBR) CBR will target to encode the video signal at the specified bit rate continuously. If the camera bit rate is set to 4096Kbps, then this will be the bit rate the camera continuously streams at. CBR is best used in high activity environments. Variable Bit Rate (VBR) VBR is an automatic bit rate setting, when configured the specified bit rate will be used as a marker, depending on the amount of movement and detail in the scene, the bit rate will automatically lower or increase. VBR is advantageous in quieter environments where there is little or no movement. Compression Compression is the application of reducing the data size of the video stream to that of the specified bit rate. The more a video stream is compressed, the lesser the quality of the video stream. Video codecs such as H.264 and MPEG4 use different algorithms to encode and decode video. H.264 is considered the more efficient, usually requiring 30% less bandwidth than that of MPEG4. When choosing which codec to select, it is important to take into consideration how the system will be used. As MPEG4 tends to use more bandwidth and disk space than that of H.264, H.264 is the most commonly used. Allowing for more storage capacity and faster viewing for remote access. Features available across the Dahua range of NVRs and DVRs include: Live Viewing (Main and Sub streams) Playback Backup PTZ Control Audio (Recorded audio, Talkback audio) Remote management Push notifications (PC software, Paid mobile app) Module 3 - HD-CVI Camera Configuration Many more features are available, if a specific feature is required by the customer then the Cop Security technical department can advise on more specific installation requirements. VIEWING CLIENTS There are multiple ways to view Dahua products across multiple devices including: Windows PC Smart PSS CMS software, Web Browser (IE, Firefox) MAC Smart PSS CMS Software, Web Browser (Safari) Mobile Phone (iphone, Android, Windows, Blackberry) Tablet (ipad, Android) BROADBAND SPEED HARD DRIVE CAPACITY One of the most important factors to consider when specifying an IP CCTV system which is often overlooked, is the NVR hard drive (HDD) capacity. Specifying the correct HDD size for the customers needs, prevents having to sacrifice image quality to achieve the required amount of days recorded on the system. Calculation: Example: IP Camera: 1080P, 25fps, High Quality () HDD: 1TB Days Recording: 11 8 Mb per second x 60 480Mb per minute x60 28800Mb per hour x24 691200Mb per day (84.4GB per day) Example: 16x IP Cameras: 1080P, 12fps, Good Quality (3Mbps) HDD: 16TB Days Recording: 29.5 Calculation: 3 Mb per second x 60 180Mb per minute x60 10800Mb per hour x24 259200Mb per day (31.64GB per day) 31.64 x16 (16 Cameras) 506.24 Total Storage per Day Internet speed is probably the most important factor often overlooked when specifying a remotely accessed system for a customer. Although remote access can be achieved on some of the slowest broadband connections, access speed will most likely suffer. On site upload speed must be considered a major factor that will ultimately determine the performance of the system when accessed remotely. Off site broadband speed is also important, however this only affects the site viewing the system, upload speed will determine the connection speed for all remote sites including PC and mobile access. An average ADSL broadband connection with a download speed will usually have an upload speed anywhere between 0.5Mbps and 1Mbps. The result of this being that viewing the system remotely would be limited to 0.5~1Mbps regardless of the download speed on site. Camera OSD Menu To access the OSD menu of a camera supporting the feature, access the PTZ control option on the HD-CVI DVR. Click the Iris + button to display the OSD menu and use the PTZ directional arrows to navigate throughout the menu. Motorised Lens Cameras including motorised varifocal lenses can be adjusted via the HD-CVI DVR PTZ interface. Access the PTZ control interface and use the Zoom/Focus controls to adjust the zoom and focus of the camera. Self Adaptive The self adaptive feature is included in many HD-CVI camera models. Turn the feature on for use with standard analogue receivers such as analogue DVRs. When connected to a DVR the camera will automatically detect whether to output HD or SD video. When in SD mode, additional CVI signals such as Audio, Alarms and Telemetry will be disabled. PTZ Control PTZ cameras require no configuration when controlled using the HD-CVI protocol. PTZ control features can be accessed via the DVR without the requirement for protocol or ID configuration. 1TB HDD = 1024 GB (935GB Usable) 935/84.4 = 11.07 16TB HDD = 16384 GB (14954GB Usable) 14954/506.24 = 29.53 Module 4 - IP Camera Installation & Configuration PLUG & PLAY Plug and play describes the installation method of connecting Dahua cameras directly to the POE port of a Dahua NVR. When connected this way, the NVR establishes a connection with the camera and allocates the camera with an IP address. This is because the POE switch of a Dahua NVR is also a DHCP server. Once an address has been allocated to the camera the NVR assigns the camera with a channel number (first come first served basis) and displays the video stream on the monitor display. REMOTE ACCESS When specifying an IP system for remote access there are multiple points to take into account. What remote access functions does the customer require? How will the system be viewed? (PC, MAC, Mobile) What is the upload speed of the site? Is the customers internet package a fixed IP or dynamic? Plug and Play is only available with Dahua POE NVRs and Dahua IP cameras, cross manufacturer installations do not support Plug and Play. Plug and Play is also limited to one camera per POE port on the NVR. If transmitting multiple cameras through a single POE port of an NVR via a switch, manual configuration is required. 11
Module 4 - IP Camera Installation & Configuration Module 4 - IP Camera Installation & Configuration The default IP address range for the POE switch within all Dahua POE NVRs is 10.1.1.1 and usually starts at 10.1.1.65. This can be altered in the network settings of the recorder. 10.1.1.65 10.1.1.66 Typical Plug and Play Installation 10.1.1.67 10.1.1.68 The Dahua config tool scans all networks the computer is currently connected to including Wired and Wireless. On first time installations all Dahua cameras should appear on the same IP address of 192.168.1.108, the Config tool will also display any other Dahua devices on the same network such as NVRs. Cameras that have conflicting IP addresses such as during first time installation, are highlighted in red. MANUAL CONFIGURATION Installations that require manual configuration of Dahua IP cameras include Non-POE NVRs & POE NVRs where more than one camera is connected to a single POE port via a switch. It is also recommended to perform manual configuration, when a single camera is connected to a POE NVR via a switch or wireless link. This is because the extra equipment placed between the NVR and Camera can delay or even stop the automatic detection process. Once the Config Tool has discovered the cameras, double left click a camera to edit it s IP address. Once the address has been set, click Modify to apply the setting. The default username & password for all Dahua devices is admin / admin. POE Switch Plug and Play POE Switch Plug and Play Using the Config Tool is a great way to discover and edit any Dahua device that is on a network including NVRs, Encoders/ Decoders and Cameras. Other functions that can be accessed using the Config Tool include; Firmware Upgrades, Camera Parameters, Batch Configure Devices and also export the device list for record keeping. Non POE NVR POE NVR WEB BROWSER ACCESS CONFIG TOOL When manually configuring IP cameras, the first step is to find the camera on the network. By default all networkable Dahua devices have a default IP address of 192.168.1.108. Each camera needs to be configured so that they all have a unique address that is in range of the NVR they are connecting to. To do this, the Dahua Config Tool is used. You can download the Config Tool from the Cop Security website, it is also included on the USB memory stick provided with your course material. To access a cameras built in web browser, type the IP address into Internet Explorer, Firefox or Safari (MAC), alternatively click the e icon in the Config Tool on the right side of the camera list. Login to the camera using the default username & password (admin, admin) For security reasons it is recommended that the default admin password is changed, a prompt will appear to request that this is done. Press Cancel to skip but this is not the recommended action. Install the Config Tool on to the computer by running the setup exe file. After the Config Tool has been installed on the computer, a shortcut labelled Config Tool will have been placed on the desktop. Before running the Config Tool you must first make sure that any devices you wish to configure will be discoverable. To do this the computer is required to be connected to the camera network. On POE NVRs this is done by connecting the computer to one of the POE ports. On non POE NVRs connect the computer to one of the ports on a network switch. On accessing a cameras web browser for the first time, installation of the web plugin will also be required. When prompted click the link to download and install the plugin. Non Plug and Play Installation Plug and Play Installation Click run to install the plugin, once installed a new prompt should appear. Select the arrow next to the allow button and choose Allow for all websites. 13
Module 4 - IP Camera Installation & Configuration DISABLING PLUG AND PLAY When multiple cameras are to be connected to a single POE port on a POE NVR, plug and play must be disabled in the camera and the cameras added to the NVR manually. Once logged into the IP cameras web browser, go to Setup > Network > TCP/IP and untick the option for ARP/PING. This will disable the plug and play feature in the camera. LIGOWAVE WIRELESS LINKS Ligowave wireless links enable transmission of network data from one link to another with transmission ranges of up to 15Km (point to point) or 10Km (point to multipoint). Each link is configured with its own individual IP address. The links are then set to be an Access Point or a Station. The Access point hosts the WiFi network and items such as the WiFi name and Security are configured. The Station connects to this network by inputting the required WiFi log on details. Ligowave wireless links have a default network setting of DHCP with a fall back IP of 192.168.2.66 Run cmd followed by the command arp a to search network the network for the Ligowave devices. Module 4 - IP Camera Installation & Configuration Point to Point 15Km Point to Multi Point 10Km PTZ CONFIGURATION Dahua PTZ cameras are installed and configured the same way as any other Dahua IP camera, except for a few small differences. The majority of Dahua PTZ cameras require separate 24v AC power input (PSU Supplied). Additional configuration should not be required to achieve control of PTZ functions. ONVIF PROTOCOL Onvif protocol is a third party protocol designed to ensure interoperability between devices. When adding Onvif cameras to an NVR the IP address of each camera must first be configured using the manufacturers discovery tool. Presets, Tours and Alarms can be configured in the camera web browser or OSD menu. Smart features such as auto tracking are configured in the camera web browser. Once the cameras are configured in range of the NVR, they must be added to the NVR camera list using manual configuration. Not all features that are you accessible on the NVR for Dahua cameras will be available for cameras added using the Onvif protocol. Often settings such as Motion Detection, Privacy Masking or even Date/Time are required to be configured in the camera web browser. Using IR Lab cameras as an example, the IPC Tool is used to discover and configure the IR Lab cameras. Ethernet 24v AC Supply When adding IR Lab cameras to a Dahua NVR, ports 85 and 554 are used. 15
Module 5 - NVR Installation & Configuration REMOTE DEVICE MENU The remote device menu lists all currently connected cameras and there subsequent IP addresses. The top section of the remote menu displays devices visible on all network adapters (POE NVRs) or default network card (non POE NVRs). The bottom section lists cameras currently assigned to channels on NVR. Module 5 - NVR Installation & Configuration ENCODER CONFIGURATION Encoders enable the integration of existing analogue cameras on to an IP system by encoding the analogue video signal into a digital network stream. Analogue cameras are connected to the encoder via BNC and the encoder is then configured on the LAN network along with the NVR. The IP address of the encoder is added to the remote device menu of the NVR, Each camera added from the encoder takes up a channel slot on the NVR. When using the Manual Add option, the Remote Channel Number relates to the camera channel on the encoder. Cameras from other Dahua NVRs or HDCVI recorders can also be added using the same method. Analogue Camera Analogue Camera PLUG AND PLAY Dahua IP cameras connected directly to the POE port of a Dahua POE NVR should not require any configuration, once connected the cameras should automatically appear in the remote device list. Each Dahua IP camera should receive an IP address from the NVR automatically and video should appear on the live display. By default, each camera should automatically record (continuous) and the Date/Time of each camera should automatically sync to the NVR clock. MANUAL CONFIGURATION When adding Dahua IP cameras to a Dahua non POE NVR, manual configuration of the cameras will be required DECODER CONFIGURATION Encoder Decoders are used to provide spot monitors using new or existing network infrastructure. The decoder is configured on the LAN or Camera network of the NVR. The IP Address of the IP cameras or NVR are added to the Decoder remote device menu. Multiple split screens and sequences can be programmed, Dahua NVRs can also be used as encoders if required. HDMI Monitor VGA Monitor NVR First determine the IP address range of the camera network, this must be different to the LAN. Use the Config Tool or Remote Menu to configure each cameras IP address. Use the Manual Add or Device Search options in the Remote menu to add each camera. By default, each camera should automatically record (continuous) and the Date/Time of each camera should automatically sync to the NVR clock. ONVIF & THIRD PARTY MANUFACTURERS Third party cameras that are supported by the NVR such as cameras that use the Onvif protocol, must be manually added to the system First determine the IP address range of the camera network, this must be different to the LAN. Use the manufacturers configuration tool to configure each cameras IP address. Use the Manual Add option in the Remote menu to add each camera. By default, each camera should automatically record (continuous). Decoder NVR 17
