Frequently Asked Questions - CCTV Power-Thru Balun 500024 MuxLab
How does a Power-Thru Balun work?
It uses two passive baluns at each end to transmit video signal and DC power over twisted pair cable. This model blocks DC from the video circuit and passes it to the camera.
What cable should I use?
Use at least Cat5e or Cat6 UTP cable. It supports distances up to 600 m for video and 300 m for power.
Do I need a separate power supply?
The balun is passive and requires a 12V DC power source at the receiver end; it then carries power to the camera via the UTP cable.
Is this compatible with 24V AC cameras?
No, this model is designed specifically for 12V DC cameras. Using higher voltage may damage the unit.
What is the maximum current it can carry?
The maximum current is typically 1 A. Verify your camera's consumption to stay within this limit.
Can it transmit HD or megapixel video?
This balun transmits composite video, not HD IP signals. For HD coax or IP, you need different transmission equipment.
How do I connect the BNC and power wires?
Connect the BNC to your DVR or monitor. For power, use the screw terminal to connect the positive and negative from a 12V DC supply, then run the UTP cable to the camera side.
Does it work with PTZ cameras?
Only if your PTZ camera uses 12V DC and analog video. Pan/tilt signals may need extra wires or a separate data connection.
Can I install it outdoors?
The balun has no IP rating; it is intended for indoor installations or protected outdoor enclosures. For outdoor use, place it in a weatherproof box.
Is there any maintenance required?
Maintenance is minimal: periodic cleaning of connectors and checking the tightness of screw terminals. Do not expose to water or extreme heat.
