Dahua Part HDBW3231E-ZT
Ultra Low Lux Starlight
A perfectly IR aligned Lens combined with ultra low lux imaging technology allows this camera to see perfectly in pitch black conditions. Night time images appear crisp, sharp and well exposed.
Ultra Sharp Image
HD-CVI allows for ultra sharp Full HD video to be delivered over coaxial or CAT5/6 cable using HD-CVI baluns.
Night Vision
This dome features infrared night vision encorporating the latest generation LED array chip for viewing in pitch black up to 50m.
Motorised Lens
The fully integrated motorized lens features auto focus and allows you to zoom anywhere from 105° down to 32° worth of horizontal view.
WDR
This camera features hardware accelerated full WDR. This helps the camera see better in challenging lighting conditions with strong backlight. Settings can be adjusted via the cameras on screen menu.
What is HD-CVI
HD-CVI is a Dahua developed technology that allows transmission of HD video signals over standard coaxial cable of up to 450m. Transmission is completely uncompressed and is not subject to latency or bandwidth issues. the HD-SDI format allows allows the transmission of audio and PTZ control over the same coaxial cable. Low cost HD-CVI baluns even allow transmission of CAT5 or CAT6 cabling. HD-CVI is very low cost when compared with both HD-SDI and IP because the camera itself does not require the same amount of processing power (ie no onboard CPU and RAM required).
HD-CVI allows a very easy upgrade from less sharp analogue CCTV (0.4MP) to crystal clear 2MP HD imaging or it can be used as a low cost method for any new installation.
