3 1. General By mounting an array of cameras on the chassis of armoured vehicles, an unobstructed view over the near surroundings of the vehicle can be maintained with the hatches closed. The Citadel Panoramic is a camera system that combines images from two 85 FOV cameras to a complete seamless 170 viewing system for 2. Main features Image sensor (2 x) High-sensitivity colour CCD mounting on a wide variety of vehicles, such as armoured personnel carriers, tanks, trackvehicles. It is designed to deliver high-performance images, even under the harshest conditions, in temperatures ranging from -25 C to +70 C.

but is not required for normal operation. During operation, the specific functions that are relevant for the user (i.e. the driver) are controlled by the serial RS-422/CAN interface.

6 6. Suggested system configuration The typical system configuration with the CITADEL PANORAMIC consists of the camera unit, in-vehicle monitor(s) & control panel and cable for power, control and video transmission connected through the vehicle s signal distribution unit (SDU). A laptop computer is typically used for configuring the settings in the camera during installation (USB interface), but is not required for normal operation. During operation, the specific functions that are relevant for the user (i.e. the driver) are controlled by the serial RS-422/CAN interface. Such functions include Day Mode/Extended Night Mode, Fog Penetration and Display Control (panoramic or left/right image). PC (for system configuration only) Cable for power, control and video In-vehicle monitor and control panel Note: 3 rd party product shown on this page are only examples. Many other products may be used in combination with Citadel Panoramic. Page 6 of 13

7 7. Mounting on vehicles The Citadel Panoramic has many mounting possibilities for a wide range of vehicles and uses. The typical use for the camera system is local situation awareness. The rugged aluminium housing, with the two integrated 85 Field of View cameras that in combination provide the panoramic 170 FOV can be bolted directly to the body of the vehicle, without the need for any additional protection measures. See Chapter 4 (External appearance and dimensions) for location and dimensions of mounting holes. Right image Left image 8. Functions and operation The Citadel Panoramic has a wide range of functions that can be controlled from an operator panel using a serial RS-422 interface. See chapter 4. (CST provides a control panel applet that allows setting up the camera via serial RS-422 for evaluation purposes) NOTE: Many of the system s basic functions do not require configuration, and are best kept in the factory default setting Picture settings Day Mode / Extended Night Mode In the Day Mode, the camera outputs colour images, allowing viewing from dim, low-light scenes to bright high-noon scenes. In the Extended Night Mode the camera is set to monochrome and 4 sec. integration. The night mode is commonly used as an observation mode when the vehicle is stationary, as the 4 sec. integration results in image latency. Settings: ON, OFF Page 7 of 13

8 AGC Controls the amount of gain (amplification) applied to the analogue video signal. When set to auto, it will compensate for variations in scene brightness, with a maximum gain of +36dB. In conditions with low scene brightness, using AGC may result in a noisier image. Settings: ON, OFF Gamma Selects the gamma curve of the video output. Normal operation is with Gamma Settings: 0.45 and 1.0 NOTE: Setting Gamma to 1.0 disables the Fog Reduction function Fog Reduction To correct for environmental influence from fog, haze, rain or smoke, his function expands the mid-range part of the camera response curve to provide higher contrast. Settings: OFF, LOW, MID and HIGH NOTE: Turning on Fog Reduction forces Gamma to DNR Control (Digital Noise Reduction) The Digital Noise Reduction function reduces random noise by averaging multiple frames before outputting an image. A small amount of motion lag may be observed when using this function. Settings: OFF, LOW, MID and HIGH Lens auto-iris control Controls the iris aperture (f-stop) of the lens determining the amount of light that reaches the CCD sensor. The control can either be set to automatic or manual. In automatic, the system regulates the aperture depending on the brightness of the scene. In manual mode, the aperture can be set by the user. The highest number represents the smallest aperture, meaning less light is reaching the CCD sensor. The iris settings of both cameras are regulated in tandem. Settings: ON, OFF Shutter speed Sets the exposure time of the camera, determining the amount of light that reaches the CCD sensor. A smaller value (shorter exposure time) results in darker images and inversely a larger value (longer exposure time) results in brighter images. It is recommended to use the lens auto-iris control or the AGC function to automatically adjust the sensitivity with variations in scene brightness. Page 8 of 13

Settings: 1/50, 1/120, 1/180, 1/350, 1/500, 1/750, 1/1000, 1/2000, 1/4000 and 1/10 000 sec. for the PAL version.

This can be particularly helpful when using the camera as a rear-view camera. Normal Mirrored Settings: ON, OFF 8.1.9.

9 Settings: 1/50, 1/120, 1/180, 1/350, 1/500, 1/750, 1/1000, 1/2000, 1/4000 and 1/ sec. for the PAL version. For the NTSC version the first two shutter speed values are 1/60 and 1/100 sec Mirror function This function controls horizontal flip of the image. This can be particularly helpful when using the camera as a rear-view camera. Normal Mirrored Settings: ON, OFF Positive/Negative (image polarity) Under certain viewing conditions it may be helpful to invert the image (turn it into a negative), in order to see details more clearly. Settings: Positive/Negative picture Page 9 of 13

Setting toggles between: 4:3, 16:9 and FULL SCREEN (full vertical resolution maintained, but horizontal compressed to fit screen) Graphical overlay markers The Citadel Panoramic is equipped with on-screen overlays in the form of distance markers. These markers assist the user in judging distance to objects and artefacts in the image. Once adjusted for horizontal and vertical position, the location of the markers is fixed in relationship to features/artefacts in the image, regardless of the video display settings. CST can customize the shape and size of the markers according to customer needs. Settings: Horizontal and Vertical position, intensity of the markers Page 10 of 13

11 8.4. Text overlay Up to 1000 individual 5 characters text-overlays can be created on the image. The X-Y position of the text strings can be configured. If a text overlay is re-written to an existing position, the contents of the previous string will be overwritten Test image In order to test the integrity of the video connection, it is possible to display a colour bar chart Command protocol All functions of the Citadel Panoramic can be controlled by sending individual command strings, with command variables, to the camera via serial RS-422 (optionally via CAN-BUS). This is typically how the camera is controlled once it is installed in the vehicle, and the driver (or another crew member) has a limited set of buttons to control the camera. NOTE: Typical functions that are controlled by the crew include Camera Video (display) settings, Day/Night mode, Fog Reduction and Mirror function. The command protocol document is available on request. Page 11 of 13
