Connect two buildings via wifi

Question

WiFi

Good time of the day!

Task:

There is a kiosk :) and there is a building nearby. There are three video cameras in the kiosk. The program for capturing video from cameras is able to give it to a specific port.
It is necessary from the office (a completely different building at the other end of the city) to go to this port and watch the picture from the cameras. But a rake ... at the moment you can only use wifi.

How much will it be real to transfer a picture over wifi? What equipment can be used?

upd Wi-Fi is

needed between the building and the kiosk (about 7 meters in a straight line from corner to corner)

Answer 2

I repeat, if there is a direct line of sight, then there is a chance.
But it’s better to somehow connect this kiosk to the Internet (empty and Wi-Fi, but the nearest one) and connect it to the second building with a VPN.

Answer 3

Put something like Yota-Egg - 4G Internet access via WiFi. The disadvantage is temporary IP, difficulties with VPN, etc.
For more complex things like VPN, you can put a nettop with USB-WiFi. The camera sends information to the nettop via WiFi, and the nettop itself is connected via VPN to another office to transfer the image. The simplest option is through RAdmin.

Answer 4

Yota sometimes threw out such tricks that at least hang yourself, did video surveillance through it (VigorFly200 + whistle from Samsung). Once the camera was cut off and did not rise, I went to the object, it turned out that our external IP had been changed. quarreled a little, returned, sat further. Then there were constant dumps, tests showed that for some reason the signal began to disappear periodically. Yota confirmed that in this area it can indeed have an unstable signal. I switched to a 3G modem, although an even more slow solution, but at least stable.

Answer 5

A similar task - visual control of a warehouse located in the nearest suburbs from the office on Leninsky, was solved by me last year. I decided with a Skylink modem + renting a permanent white IP with a monthly payment. The camera, however, was also IP. Therefore, everything worked without a computer, on the controlled side there was only a modem, a camera and an uninterruptible power supply. You can control it from anywhere in the world. Several cameras could be scattered on different ports.
True, the modem lost contact with the BS during a long idle idle, I had to buy a modem power control device via GSM-SMS, and reboot the modem remotely. And Wi-Fi in a metropolis is a lottery, even if from a neighboring building.
PS By the way, according to your specifications, I still don’t understand, do you need to raise wifi between the building near the stall and the stall itself, or do you need to connect the two ends of the city? The last one is not real!
