Can only a single wire be used for CCTV video transmission

[deeepak 0]

Hi All

 

I have hikvision DS-7308HFI-SH DVR (8 channel) with 6 analog 650TVL CCTV cameras.

When construction of my house was going on then wiring for my 6 cctv cameras was done. Below is the wire used for CCTV cameras:

 

 

However I want to attach one more CCTV to my DVR but the problem is I do not have any dedicated CCTV wiring for this.

 

I am using an adapter to power my new CCTV and some how I have only single unused copper wire (used for household electricity like i the picture below) spare from my new CCTV camera to my DVR .

 

 

My question is can I use this single copper wire to transmit video signals from my CCTV to DVR .

if two wires are must then can anyone suggest a device that can multiplex the signal of two wires at CCTV end so that they can be transmitted over a single wire and later demultiplex at DVR end.

If you are not using the audio, it might be worth a try using those leads?

IN THEORY you could multiplex the two signals , modulate an RF carrier & feed it down the single wire which would act as an antenna. You would then need to have an RF receiver/demodulator then demux it - IN THEORY. I've never seen it done.

Hi rebel998

 

Thanks for the reply.

 

Of course I can but the problem is I do not have CCTV wire for that 7th CCTV camera. All I have only a single copper wire (shown in second pic)

Hi the toss

 

Thanks for you reply.

 

You are right, I have used a RF wireless transmitter to transmit signal from CCTV to DVR and it works.

 

Do you aware of any device that can do the same job using a single wire as carrier (not wireless).
