Is it possible to convert analog video signal to IP\RTSP?

Question

Arduino

The problem is this:
At the entrance there is a video surveillance system assembled on IP cameras, 6 cameras, and an 8-channel DVR for IP cameras.
But there is another camera - an analog one from the intercom on the entrance door, which I would like to connect to a common video surveillance system.
I would like to get by with little blood, and take an inexpensive device that would convert an analog signal to IP.

I imagined it something like this:

From this article, I understood that this board is what I need. But having ordered it, and having worked with it, I realized that the board is not at all about this case. As it turned out, this is an IP camera module without a lens, analog video is not connected to it in any way, which is a pity, such an idea has broken off.

Perhaps there are some similar budget solutions, how can I convert from analog to IP?
Option to buy additional I do not consider a registrar for one camera, or replacing the current registrar with a hybrid one as inappropriate. And the camera is needed from the intercom, hanging a digital one next to it is also not an option.

Answer 1

There are many models of hybrid DVRs available on the market. They are called hybrid because they can work with both IP cameras and analog ones (moreover, from analog ones, for example, both AHD and those very ancient "just analog" ones are supported immediately). But you need to study the characteristics. There you can select the operating mode from several options. For example:
mode 1 - only 4 analog
mode 2 - only 8 digital
mode 3 - 2 analog + 4
digital

Answer 3

Buy a DVR for 4 channels is the most logical decision. And best of all, the manufacturer of which the cameras - so that they are integrated.
There are inexpensive boards from XM (xiongmaitech).

Answer 4

You need an IP encoder like beward b102s they are both single-channel and multi-channel.
