Hey!
Task: to organize a video surveillance system for 5 objects located within a radius of 5 km. The cameras (15 pcs) will be located outside, the temperature regime will be +30 ... -30. Faces and license plates must be clearly visible, sound is not required. You also need access from a remote computer and the ability to save video for several (3-5) days.
The facilities do not have Internet access. There is no 3G either, only GPRS. I do not think that this speed will be enough to broadcast video. There are ideas to install Wi-Fi amplifiers. Which ones will pull 5 km?
I would like to hear your opinion on the implementation of this project, with the names of the necessary equipment. The budget is limited, I would like to manage on my own. Is it possible?
Thanks in advance for advice!

Direct visibility?
1. Directional access
points 2. At each point, you need to organize a cabinet: poe injector for the camera, poe injector for the antenna, uninterruptible power supply, switch into which you need to plug the injector from the camera and the injector from the antenna.
You need to draw a map and evaluate how many access points you can put. It is possible to put one omnidirectional access point , but there is a problem - it does not hit far.
If the visibility is direct without obstacles - good.
3. I recommend Liniya software , firstly cheap and angry, support is quite operational, I have not observed any problems with the software.
Note: Real-time video is eating the channel, God forbid, don't think that the traffic is light, the load on the server is also decent, this is at least processing and compressing several real-time video streams at once. It is better to organize an HD cluster on a separate server, thereby offloading the processing server.

5KM is a bit too much, of course, antennas are good, but not as reliable as, for example, optics, the question is, can you, for example, hang optics on poles or buildings?
If so, then look at these pieces of iron , an interesting idea, but I myself have not yet had a chance to try it.
I would not advise an analogue, I would suggest that it is better to consider IP cameras from the Cameron company in Novosibirsk, the price is the same as for analog cameras of good quality, + they have NVR recorders for IP that are not expensive.
Again, the question is how much money for equipment!
If it is possible to buy a sevak and not a DVR, then it is best to take IBM or Lenovo + software from Macroscope.

I think it is important not only to install the video camera correctly, but also a lot depends on whether the model is of high quality, the resolution it supports, and whether there are motion sensors. We have already solved this problem at the enterprise. In the ZENITH CCTV online store, we purchased Zenith 5 cameras for outdoor video surveillance. They fit perfectly in all characteristics, they do their job perfectly! I was pleased with the convenient options - Wi-Fi connection, connection to the camera from the phone.

Wi-Max in theory should pull the distance. Although FOCL is more reliable to lay.
In order for faces and numbers to be visible, you need to at least calculate the focal length of the lenses and the resolution of the cameras using a lens calculator, although it is even better to use video surveillance design programs.
I wrote a detailed answer in the topic "the theory of building a video surveillance system" about using a similar program:
