Single Channel Video Balun & Power Receiver for Camera Side
Model: VBU110RJ-DCPA
 
VBU110RJ-DCPA is a passive video and power balun device capable of transmitting baseband video signal and delivering 12 VDC power to the camera using UTP cable. This device is designed to be used with VBU05DC-1UPA, VBU09DC-1UPA and VBU16DC-1UPA passive video balun power assurance hub. Passive video signal transmission up to 1000ft / 300m and provide the camera with 12 VDC @ 300mA maximum. It has a very efficient step down power converter and regulator. It also supported the following baseband video signal systems: PAL, NTSC and SECAM.

Explanation for Voltage and Power Drop

Max Current per Channel = 24V DC X 0.4A = 9.6W

1: If TX distance is 0 ft = what is the Current = (9.6W * 90%) / 12V = 0.72A

Note: 90% is the efficiency (since we are using High Efficiency component, there is virtually no heat being generated) in another word our maximum current output can reach above 0.7A.

2: If TX distance is 300 ft, base on the characteristic of the power cable and the resistant calculation @ 18 Ω. First we have to find two answers, one is the voltage drop and two is the Wattage consumed.
A: The drop in voltage from the cable is: 0.4A*18 = 7.2V, so the voltage arrived at the remote end will be: 24-7.2 = 16.8V.

B: The Watt consumed: 7.2V * 0.4A=2.88W. The Wattage supplied at the end is = 9.6W – 2.88W = 6.72W. After the step down conversion, the supplied Wattage is = 6.72 * 90% = 6W.

So, the final output current is: 6W / 12V = 0.5A

Of course the quality of the UTP cable that you use will affect the voltage and power drop.

How does a balun work?
Baluns are used to convert between "Balanced and Unbalanced" electrical signals.
Baluns work by transforming the original unbalanced (video/power/data/etc) signal to a balanced frequency used by a different cable, like CAT5 UTP. Not only does this reduce interference, but it also allows you to transmit a signal much longer than the original application would allow. Baluns are always utilized in pairs. One balun is needed to convert the original signal to a new frequency, and another balun is used at the other end to revert to the original frequency.

"Passive" Video Baluns do not require power, and can extend a signal up to 2000ft (B/W)
"Active" Video Baluns require power, but can extend a signal up to 8000ft (B/W)
