How to connect 2 security cameras to one TV

[tallyho8]

Once again I ask my TBNers to help me with a problem unrelated to tractors.

I have 2 security cameras in my barn. One has an RF modulator set to channel 3 and the other has an RF modulator set to channel 4. My barn is 1000' from my house with 1 cable running to it. Either camera will work well when connected to the cable.

My question is " Is there a way to connect both cameras to the cable and be able to watch either camera by simply changing the channel on my analog TV from channel 3 to channel 4?"

With the modulator set for different channel just connect with a 2 way splitter then the tv would do your channel switch when you choose. or still video could purchase a switching unit and have a time set for 3 to 10 sec. per camera.
a good camera shop could give you several ideas.

All the splitters that I have seen have 1 in and two outs. Are they bi-directional where I can put the 2 ins from the cameras on the connections marked OUT and run the connection marked IN to the TV?

You need a combiner.. Amazon.com: CHANNEL VISION HS-2 2-Way PCB Based Splitter/Combiner: Home Audio & Theater

Install the splitter "backwards", with the two "out" ports going toward cameras, and the "in" toward the television. Boom, your splitter is a combiner. You'll lose approximately 4dB by combining, but this is your best option.

You don't specify the type of cable, but 1000 feet is a looonnnggg run for most basic coax. You may need a small drop amplifier at the barn end.

I get good reception using one camera. If the reception worsens using both cameras I will try an amplifier. Thanks for the ideas.

This will work. I was in electronics my whole life so know it will. In the old days of twin lead you could just tape about 3' of twin lead together, wires not connected and that would also work. You could made a splitter for nothing but it's hard to do with coax.

Finally a subject I know something about. A good quality splitter will double as a combiner. The channel vision brand is pretty good, that's what we used to use. Its been forever since we could modulate a camera like like that since the digital technology took over. For the run you have you might end up needing that amplifier as mentioned but I would try it first to see how well it works without. One thing we always found helpful was to separate those channels a little. We would typically skip a channel or two between cameras so they wouldn't bleed over onto each other.

Good luck.

I would like to be able to skip a channel but the only modulators that I have found only have channels 3 and 4. Any suggestions?
