Details
The 8-channel transmitter or receiver can transmit video signals from eight cameras via two 8-wire CAT5e UTP cables, preserving good quality. Each channel matches the impedance of unbalanced coaxial video output/input (75 ohm) to the impedance of the balanced line (100 ohm), ensuring proper video transmission via cat. 5 twisted pair cable from many types of cameras:
- PAL (CVBS) up to 400 m
- HD-TVI, AHD up to 200 m (720p) or 150 m (1080p)
- HD-CVI up to 200 m
Distinguishing features
- interference-free transmission of eight video signals
- simpler and cheaper wiring - the eight video channels are transmitted via two UTP CAT5e cables
- passive components - no power supply needed
- built-in anti-interference filters
The type of cable and connector wiring
A UTP cable rated CAT5 or higher is required. The quality of the cable used has a direct impact on the image quality and transmission range.
The wires should be connected in accordance with the scheme TIA/EIA-586B for RJ-45 connectors. Coaxial cables terminated with BNC plugs are to be connected to BNC sockets.
