The simplest solution is take it over CAT-5. At 500ft it will easily give you 10Mbps and that is more than enough for CC-TV quality video.
Yes 100mts is the max fot 100Mbps. All you need is around 2Mbps for high quality.
To accomplish this you need a CCTV to ethernet media converter. But commercial solutions can be expensive. You need to hunt around.

Total cost - About 150$ + CAT 5
This device takes in Audio+Video in and then trasmits over CAT-5 and then again the plugs into a deconvertor to give you back the RGB
solution no 2 if you dont like wires(More hacky) :

Wireless transmission, but the range is usually limited to 100meters or so.
But if you can find yourself some college kid(electronics chap) he can make you a directional antenna which will easily do 300-400meters!
But I am not too sure about the legality of this as indian laws are pretty warped. Infact 802.11 was allowed a few years ago!

There are 2 cameras at the building, but the TV and the video switch (with remote) are to be placed at home. The contractor got us to lay the cable from the cameras to our home, roughly 400 ft long cable. All this happened without a hitch.
The installer from the camera company came 3 weeks back, he connected the camera at one end and the video switch (12 inputs/2 outputs) at home. But nothing showed up on the TV. Then the installer declared that it would never work over 150ft. But the contractor over phone swore it will. We asked the installer to walk away with his camera.
Today a different installer came from a different camera company. First I asked will it work over 400ft, he says yes. Again he went through the same motions. But this time I was home when he was connecting the video switch. He connected the two incoming video RCA jacks to 1 and 2 inputs on the video switch. Then to my surprise he pulled out a RCA stereo audio cable and connected the red connector to video output 1 and white one to video output 2.  Then he proceeded to the TV and was about to connect to Red and White input on the TV front panel. I stopped him at that point and forced him to use the yellow video cable and connect only video 1 output to yellow video input on the TV. Anyway, it didn't work, not even static.
I had one question to both installers, can the camera video output travel 400ft without any initial signal amplification? The first installer said 150ft is the limit and second one says an amplifier at the video switch is the answer. I am not buying both argument. I am thinking video signal has to be boosted before connecting to the long wire. But then I don't have first hand experience. The installers have experience but too dumb to understand this installation. Instead of saying they don't know, they keep giving ludicrous suggestions like boosting the signal at 150ft (middle of a field ) or take it via Internet (who will pay broadband charges???), or use ethernet (are they buying us computers at both ends??? Also ethernet maxxes at 100mts), etc, etc.
So, what is the solution here. We have already spent 10K for laying the 400ft cable. But we are stuck with dumb installers who talk sheer non-sense. Need some suggestions here. |
