How to make an analog IP camera? What are analog to digital converters?

Question

CCTV

I have several analog cameras that are not large in size. These are not even cameras, but camera modules the size of a quarter of a matchbox. They are powered by 12 volts, the output is analog audio and video. Pretty decent image quality. I bought it in China, played around, put it on radio-controlled models, and now they are lying around. I thought about putting them under surveillance. There is already a monitoring server, it's a Synology NAS. But how to convert them to IP? I understand that an IP camera is very loud, it has its own video analytics, and different texts are superimposed on the video and much more. But can you at least get a video stream from them as in IP in order to hook it up to the surveillance server? There are such converters, analogue at the input, WiFi\Ethernet at the output? I googled for a long time and didn't find anything.
As an extreme option, even if it is Analog video to USB. I connected a regular webcam to the router via USB, and through the mjpg-streamer, and the surveillance server receives the video stream link and successfully works with the stream, thus I received an IP camera from the webcam and router.
Well, does anyone know how to solve the problem?
PS I know that there are surveillance servers for analog cameras, but I don't like this way. I need to get a stream by IP and write everything to one server in one system.

Answer 1

It can be done using the most common hybrid DVR or more specialized devices such as the GrandStream GXV3504.

Answer 2

IP cameras have the same modules at the moment.
And they cost ridiculous money, something around $ 10.
Than to fence with an analogue, look better in this direction.

Answer 3

Just get an IP camera, it's 30-35 dollars.
