4-way camera diplexer CEW 1884

Has the capability of connecting 4 cameras with an internal RF-modulator

Every TV-set can be used as a monitor
Succesive switching through camera image through 1 UHF TV-channel
Constant display of the cameras through 4 UHF TV-channels
Simple feed-in in existing antennas distribution systems
Only one coaxial-cable between every camera and the CEW 1884
The power supply of the camera is done through the coaxial-cable.

The new 4-way camera diplexer CEW 1884 connects up to 4 audio/video-cameras with integrated RF-modulator (e.g. ANKARO CAM 400 /500 C-MOS / CAM 600 Color CCD)
Each camera is connected to CEW 1884 only with one coaxial cable 75 Ohm.
CEW 1884 provides the possibility of showing the camera's image in succesive switches of about 5 seconds. All the connected cameras must be tuned in the same RF-channel. One TV-set that is tuned in defined RF-channels serves as a monitor.

CEW 1884 traces the number of connected cameras and adopts the succesive switching. For this reason there are no voids in case less than 4 cameras are connected.

CEW 1884 can similarly transfer the signals of the camera constantly. That's why the 4 cameras must be tuned in 4 different RF-channels. A void of one or two channels must exist in order to avoid disturbances.
Sound is also supplied.
When CEW 1884 is connected to a CATV-system one decoupling-amplifier must be placed between the CATV house-connection-point and the distribution system so that the transmission to the public CATV-network is avoided.
