VPD Design Considerations
Step 1: Measure or calculate the distance from each camera to the DVR (DVideo).
Step 2: Calculate Maximum possible distance from each camera to power supply
(DPower) using the Power/Distance Chart:
• If (DVideo) < 750 feet AND (DVideo) < (DPower)
Use a combiner transceiver at Control Room.
• If (DVideo) > 750 feet
Use a combiner at Mid-span location closer to the cameras.
Use an active receiver hub at control room.
Step 3: Use a single channel GE combiner transceiver on the camera side
considering the camera voltage.
