PHYSICAL SECURITY OVER THE NETWORK

Transcription

1 OVER THE NETWORK 1

2 IPTV and Video Many users now require CCTV recordings for 90+ days Focusing also on the storage and associated costs of IP Video systems NAS or SAN IP storage systems for large camera deployments What resolution continuous or motion based recording frame rate Security of the stored data is important Can not have data loss due to individual disk and equipment failures Analytics Based on video analysis of the feed, decision are made store data alter frame rate or resolution identify threatening/interesting events Video Viewing Most viewing is for historical investigations Some live streaming in retail applications 2

3 Resolution Pixel Count How many physical pixels can an image sensor process More pixels typically means better quality, but also more bandwidth Sensor vs Stream At times the camera will stream data at a lower resolution than its sensor captures the image Could be by design or a configuration error Compression Surveillance video is almost always compressed Reduces bandwidth and storage requirements without impacting image quality 3

4 PoE Does PoE always make an installation easier Some customers have experienced camera s dropping from the network Secret to PoE In the Wire Cat 5/5e/6 UTP which limits crosstalk and reduces power loss In the Switch which acts as a power source for the camera s How much power does the camera draw and can the switch support this? Concerns Higher resolution video impacts the power needs of a camera Compression, resolution and processing ALL takes power More power consumption by the camera leaves less power available for the heater or blower if the camera is mounted in an outdoor enclosure Need to now monitor Power! 4

5 Proper Network Configuration Verifying proper VLAN deployment Network VLAN VoIP VLAN IPTV VLAN VoD (Video on Demand) VLAN Managing VLAN issues Visibility between services and devices Validate correct VLAN configuration! 5

6 Camera Characteristics Fixed vs PTZ vs Panoramic PTZ - Moveable through the use of panning, tilting and zooming Panoramic can record in all directions Colour vs Infrared vs Thermal In day time or lighted areas, color cameras are obvious choice Standard Definition vs Megapixel Megapixel is now the standard resolution IP vs Analog IP cameras digitize the video inside the camera, while analog cameras require an encoder or DVR to digitize the video Wired vs Wireless Wireless offers more flexibility but need to be vigilant with security and wi-fi issues out of your control that can affect image quality Lots of Data over the Network! 6

7 Now how do we Connect these? IP vs Analog Both IP and Analog (via an encoder) cameras can communicate over IP Panoramic can record in all directions Wired vs Wireless Video can transmit through your copper/fiber infrastructure or through the air Wireless is gaining momentum due to higher cost of running cables Lots of Data over the Network 7

8 Viewing the Data Local Viewing Directly from the Digital Video Recorder (DVR) Lets the video management system double as a viewing station Remote PC Viewing Most common method Standard PC s used to view live and recorded data via proprietary application or a web browser Mobile Viewing Allows field personnel to immediately check surveillance video Gaining traction with growth of smartphone technology Video Wall Viewing Large security operations with hundreds or thousands of cameras Ability to switch and automatically display feeds from different locations Data now over the WAN! 8

9 Effective Troubleshooting Users can't connect Devices stop talking to each other Physical layer changes are causing problems New networking technologies have caused even more problems When everyday issues like these come up, the simple mandate is Make it work! 9
