What kind of camera to use in the elevator?

Question

CCTV

Look, I don’t understand anything about cameras at all. And, in principle, I don’t see much point in delving into it. Therefore, I ask you to describe on your fingers to someone who understands.
The task is this, I am the head of a large house, where you need to install surveillance cameras in the elevator to determine who and when is pigging there.
That's basically all of the TK.
I think that it should be fixed somewhere outside the elevator cabin.
But with power, with video storage, with viewing the recording, I still don’t understand at all how it should happen.
In fact, in the elevator, 110W is supplied to the light bulbs, but I am now redoing it to 220 (to put LEDs). So the power is still all right (what kind of power supply) How and where should the signal go - that's what I'm especially interested in. It is desirable that it was possible to watch in the home computer.
Or maybe the DVR needs to be installed with a SD card?
Advise a good option how to solve so that everything is correct. And of course, the price is relatively reasonable.
Thank you.

Answer 1

Ordinary protected dome camera, or built-in anti-vandal. Connect either via a shielded loop through POE, connecting it to the main cable route in the elevator (the main thing here is that the power cables in the armor do not fray the loop during operation, in general, their problems), or power is taken in the elevator, and communication over the air.
If the house is small (9 floors) and the roof of the elevator is not made of steel, then you can try to just put a wifi camera, and on top, near the engine, an access point. But it must be checked in each case.
However, it is better to take either the option above with a wireless transmitter, or buy a Wifi bridge. One part of the bridge on the roof of the elevator looks up, the second in the shaft looks down. The main thing is to adjust them to each other.
Now that we have the signal from the camera in the machine room of the elevator, we need to lead it down the cable to a point. where the registrar will be. I recommend ip cameras, because no problems with interference as long as the cable runs close to the power equipment. If there are rats, it is necessary to pull everything in a metal hose. If the length is more than 100m, then it is necessary to put active intermediate equipment into the gap. Ordinary TpLink switches in a metal case for 5 ports will do (they cost 1500r in St. Petersburg). Put them in the shield in the box, powered from the phase and that's it. If you pull an analog line with a coaxial cable, then nothing is needed, the main thing is not to bend the cable.
In general, they brought it to the registrar, connected it, inserted the HDD, set up the recording, displayed it on a separate monitor, and that's it.

Answer 2

You need a wireless camera. There are two options - either a miniature camouflaged one or a full-size vandal-resistant one.
You need something like this (not ads).
Some freaks put on a dummy.
In a good way, you need to put a dome with infrared illumination in order to catch freaks twisting / breaking light bulbs.

Answer 3

When I did video surveillance (though not in the elevator), I organized the following scheme:
A camera (1000r) is plugged into the router (for 2000r) with a usb port and video is transmitted through mjpg-streamer (the program for the router is free). The only problem is that there is no sound. And so for 3000r an analogue of an IP camera. I have a video of 1280x720, 25 frames per second
. In my opinion, in any case, you need to pass a patch cord into the elevator, because making a wireless network for the entire elevator shaft is not very logical (you can put it in the elevator and, for example, from above the house via a directional antenna, but they cost 5000r each, and a regular router, I think, will not be able to provide normal transmission due to the large distance to the elevator.However, I could be wrong)
Putting a camera with a flash drive is not an option. Stolen along with the flash drive. If you hide it outside the elevator and just put the lens inside the elevator, then you are tormented by constantly removing it and putting it back

Answer 4

Well, what a twisted pair in the elevator. Is it a multicore that goes to patch cords, but even with it what will happen after 300-500-1000 flexion-extension cycles?
Install a wifi bridge on two access points: one on the roof of the elevator, the second on the technical floor. Which points to choose depends on the distance (number of floors of the house) and your budget. Installers advise Ubiquiti NanoStation.
