Transferring an analog camera signal via wi-fi to an analog receiver?

Question

Iron

Good day to all
There is a receiver for recording from analog kt & c cameras, it is required to put the camera at some distance from the receiver (~ 250m), it is not possible to stretch the cable, but there are 2 directional antennas that function at this distance, tell me the solution with which you can transmit the signal from the camera. There should be something similar to such a system: from the camera side, an analog-to-digital converter => wi-fi transmission => digital-to-analog converter and connection to the receiver
Thanks in advance for the answers

Answer 1

You need such a thing
Here is such a thing - Encoder ~ $ 300
+ a decoder on the other side, also + ~ $ 350-500
You can find it cheaper of course (many tried it but it didn’t start), but only such a piece of iron solved the problem with a remote security monitor on the old surveillance system, but there the investment of a thousand bucks was fully justified due to the not frail size of the video surveillance infrastructure (factory), it would be much more expensive to redo it.
I have not tested it on cameras, but it should work.

Answer 2

The receiver means the registrar? DVR or something else? I would do without a registrar at all. Buy an old computer - 5000r, a video capture card (for Ali 1.5-2 thousand) and a hard drive for storing the archive. And with the help of a Wi-Fi bridge, connect the computer to the local network. Almost any video surveillance program has a web server, and to get a picture on remote computers, it is enough to go to the video server computer through a browser, or install a client. If the registrar supports Ethernet, then you can do without a hard disk and set up storage of the archive on the registrar.

Answer 3

You are terribly far from reality.
To transmit an analog signal, there is equipment Wivat videoglaz.ru/besprovodnye-peredatchiki-audio-i-vid...
In the assortment there are also 4 channels for different ranges.
If you want perversions with your equipment, there are single-channel IP video servers
