Project Description
BHVD401
Together with up to two analogue PAL-video cameras, the BHVD401 forms a monitoring system. The video image on the display is rather depicted in full screen or split screen mode. Moreover, power supply and camera heating are provided by the BHVD401.
The selection and fine adjustment of the individual camera image sections is set via a control panel on the front of the housing.
The firmware of the BHVD401 can be updated via a web interface.
Example of use:
Retrospective BHVD 401 together with a left camera BHKL 10 and a right camera BHKR 10, through which the left and right area of a rail vehicle can be monitored in the reverse direction.
