1 Channel Passive CCTV BALUN - Video/Power over Cat5
This pair of single channel passive video baluns will carry video and power over Cat5 Ethernet cable, giving you the ability to utilize straight network cables to connect your cameras. Simply connect the BNC ends to your camera and your recording device or display, connect the DC ends to a Power Supply and the Camera, then connect your network cable through the RJ45 jacks. Depending on camera power draw, power output, cable size, and environment, results will vary. Average conditions allow transmission up to 1,000 ft. On longer runs video quality might be slightly reduced.
The DC jacks have a 5.5mm barrel size and 2.1mm pin size.

PROS: I installed a security camera system using CAT 6 wire and these passive baluns. The installation process was relatively easy. In most locations, I was able to place the balun directly in the wall space behind the camera and used a low voltage frame and wall plate so that I would have access to the balun if needed in the future. In two locations, I had to install a small electrical junction box adjacent to the camera to house the balun. On the DVR side, the CNB connection wire is an adequate length to enable an easy connection to the back of the DVR. The price for these baluns is very low compared to others on-line or in stores.
CONS: I purchased 15 baluns for my 12 camera system ... I bought extra baluns in the event that I wanted to add more cameras. While the size of the camera side balun is a little larger than I had hoped, I was able to fit them and the connections into a 4" electrical box in those situations where I could not place the balun in the wall. However, I am concerned about the quality of the baluns. Two of the 15 sets that I purchased did not work (both were the camera side balun). I double checked my wiring and tested all of the connections, however two of my cameras would not work. I replaced both of the baluns on the non-working cameras, and the cameras worked. I then changed the DVR side balun and then the camera side balun for these two cameras and discovered that the two camera side baluns were defective. While the price for these baluns is low compared to others, the quality control also appears to be on the low side.
PROS: They work as advertised.
CONS: Cost and power connection.
If you do not see any picture after you install this product you most likely have the Ethernet cabling done incorrectly. I had the same issue and as soon as I changed the cabling everything started to work correctly. I followed the T-568B standard Straight-Through.
PROS: - Easy install
- No additional configuration needed.
- Patch a Ethernet cable (RJ-45) and you will be all set to go.
CONS: - Power cable could be a little longer.
Straight cable connections without punch-blocks are just fine.
I'm pleased that the power is also carried over the cable. All 30 of the infrared LEDs light up on my camera with the same quality as direct-wired siamese cable.
The video quality over 100 feet of CAT5e cable is indistinguishable when compared to 100 feet of BNC cable.
It connects easily to the DVR. The reason I mention this is that another reviewer indicated that it's hard to connect to closely-spaced BNC ports, but the version I received has a pigtail of wire between the balon and the BNC connector which gives copious amounts of space to work with.
The transmission of power is an added bonus whose advantages cannot be overstated.
Documentation is incomprehensible but there's not much to worry about, here.
You will have trouble weather-proofing the outdoors end. Monkey poop works for the BNC and power but not the Cat5e connection.
For the weather-proofing, one solution is to fashion a box outside to protect the balun and run a short length of BNC+power siamese cable to the camera's location but that's a lot of extra work, so you need to compare the weatherproofing effort against with re-wiring the premises with BNC.
PROS: The picture quality is the same as direct siamese BNC cable that I have as long as no punch-down blocks or other things are between the baluns.
Straight wiring performance is equivalent to more expensive siamese wiring (see Cons).
CONS: I can't think of any cons to this item that aren't caused by your premise wiring. Naturally, your installation may have more than one punch-block which will degrade the signal, so keep that in mind when installing a camera using this balun.
PROS: I tried thise Baluns on 750 ft Cat5e cable on 4 story building and I doubted at first the stentgh and quality of the video and power over this long distance but instead the video quality was great and the voltage at the other end was at 11.89V DC.
CONS: not water proof
Glad you were pleased with the baluns and everything worked out well for you. My apologies on the bad unit, but if you need a replacement on the one defective unit I would be happy to do so I would just need an order number to get the process started.
PROS: Works Flawlessly
PROS: best product easy use and good price
