Although the default tools such as raspivid and raspistill can be used for this purpose, supporting RTSP requires the use of third party tools. The next task is to make the Pi work like a CCTV, that is to constantly take frame snapshot and record videos and make them accessible on the network.
The module has 2 IR LED modules on both sides screwed to the camera module located at the centre. Despite the fact that the LEDs are permanently on, the picture quality is satisfactory for both day and night modes and the camera module is still a good value for money. The one I bought for less than $10 look the following: The second challenge is to find a reasonably cheap module that supports night vision.
Longer cables are also available and although the documentation warns against using long cables for fears of data loss, I have not encountered such issues when using a 5m cable. Fortunately many such cables (length approximately 80cm) are available on eBay for around $2 each:
The first thing to do is to find a suitable cable, as the cable that comes with the camera board does not fit the Pi Zero. I have a bunch of unused Raspberry Pi Zero Wireless and associated camera boards from previous projects and decide to use them as cheap CCTV camera replacement.
