THE CAMERAS
| Pan/Tilt Zoom
Camera The proposed dome camera system is a compact, lightweight and intelligent security device comprising camera, pan/tilt drive, receiver and CPU-based electronics all in an attractive and robust enclosure. There are 79 programmable preset positions and 16 individual programmable privacy masks. Motion detection capability is available. For each preset, there are 6 programmable zones for motion detection, each having 3 sensitivity levels. Eight tours are available with 32 steps per tour. Pan and tilt functions are externally controlled, continuously variable and programmable to be enabled or disabled. There is a programmable autopan function. High-resolution (580 TV line) colour/mono camera low light capability (min. 0.02 lux) Motorised 23x optical and 12x digital auto-iris zoom lens 79 pre-sets 16 privacy zones Weatherproof to IP66 (protection against dust to high-pressure jets of water from all directions). Fitted with a thermostat and heater, which will maintain the operating temperature at a suitable level. The heater will de-mist the housing glass. Video Pan View: 360°. Video Tilt View: -2.5° (-2.5° above horizon) to 92.5° (-2.5° past vertical). Pan Speed: Variable, 0.1 to 360°/sec (120°/sec in 22X). Autopan Speed: Variable, 0.1 to 42°/sec Tilt Speed: Variable, 0.2 to 150°/sec (90°/sec in 22X). 6 programmable motion detection zones with 3 sensitivity levels; image freeze during preset solve; flip (invert) video image. Image Device; 1/4-inch interline transfer CCD Sensitivity; 0.02 lux at 40 IRE, f/1.6, auto 1/5s S/N Ratio; Better than 50 dB Dimensions H x W x D; 60 x 50 x 88.9 mm Wireless System The wireless system specified transmits digital data in a point-to-point network. The wireless networks operating frequency band is the 5.4GHZ range, used for specialist systems such as this rather than for standard home/office wireless networks and the like. The system is secured by data encryption and MAC address filtering such that data cannot be intercepted. The wireless system operates as a mesh, whereby all nodes communicate with all other nodes. The optimal route by which to send data is learnt by the equipment and adopted. |
