How to organize video surveillance of several high-rise buildings?

Question

CCTV

I ask you to share the experience of people who personally organized video surveillance of their apartment building.
Pitfalls, organization of those. parties, legal issues and all the most useful things you can smoke on this topic. I would be grateful for links to capacious and high-quality material.
Purpose:
Any occupant of a particular house can access all cameras installed on the house. (Surveillance of parking, exits from the yard)
Surveillance format: (as it seems at the moment)
Online surveillance + recording to a remote data server from the camera for a month. The tenant enters the Internet portal, enters his login and password, and several frames open on the page with the broadcast of the cameras of his house and a filter by date for the monthly archive.
Questions:
Are there online services described above? What cameras to use? Wi-Fi\Wires? What is the best way to mount the camera?
Is it possible to organize a collection of money through the Housing Office? After all, in fat bills, for example, the cost for servicing magnetic doors to the entrance is included. Everyone pays rent

Answer 1

Good afternoon. We were engaged in house maintenance by video surveillance (they did all the installation, adjustment, etc.), although the profile is not ours at all.
In principle, nothing complicated - because. we installed both analog and digital cameras, I can say that the analog is better in terms of reliability - for 3 years there were a couple of falls, one due to a not very high-quality hard drive, the other - when the electricity was cut off in the whole house - for some unknown reason the DVR did not rise.
On WiFi cameras - everything would be fine if it were not for the signal level - where it was weak, the cameras fell off and did not connect automatically. (but they have software with a login-password and everyone can see everything, if desired, you can configure it remotely). We used TP-Link cameras for 3500 rubles, then we found the Chinese ones a little more expensive, but the street ones did not test them :)
As for the payment - yes, you can include it in the payment, but not at the level of the housing and communal services, but at the level of the HOA - just like with intercoms in general - for this it is better to talk with the house manager :)
PS installation of analog cameras will cost more , if they are scattered in different places and far away, under the same conditions, WiFi will be cheaper.
If you have something specific to suggest, then ask, I'll remember :)

Answer 2

It all depends on the budget.
I will give examples:
If you use analog cameras, you will need:
- a DVR (which will be an analog signal, make it digital)
- analog cameras (depending on what quality you want, it depends on TVL)
- of course, wires (UTP / FTP)
- "folder" adapter power + RCA to RJ-45 (It's still easier to pull 1 cable, and besides, it's cheaper to buy a 300 UTP bay than 300 copper cable and video cable.)
- junction box for each analog camera. (Regular junction box, for wiring)
- power supplies for each analogue.
- a bracket with protection (not necessary, if there is no chance that something will fall on top of the camera, but you may need a non-standard bracket to get a better view)
All this "crap" is connected to the DVR, a provider with a white IP is connected to the DVR. Using this IP, you can go to the webmord and watch all the channels, but a compressed (but you can switch) digital picture is sent to the webface (imagine how the video quality is lost (analog-to-digital conversion + compression)). In frequent cases, the manufacturer of the DVR has software for connecting specifically to the OS and receiving an uncompressed picture, usually through the software you get only a digitized picture in real time and watch it on your computer in this software.
Pros:
- cheaper than IP cameras
- fault tolerance of cameras
- convenient installation
- there are no recording delays on the DVR.
Cons:
- scalability depends on the channels in the DVR.
- video quality
- due to insufficient quality, the possibilities for connecting intelligence modules have been curtailed (recognition of faces, car numbers (if the cameras are of course not at point-blank range =))) What
can I say about the IP of the video camera, what will be needed:
-va cameras, more precisely streams)
- IP cameras themselves
- UTP
- network equipment (a router of some kind)
- mounting box
- power supplies (usually included)
I would not recommend using Wi-fi cameras if you can throw a cable.
It is better to buy iP cameras with POE support, and about IR (analogues are also with IR (you can also judge the range)) you should not forget. Well, it all depends on MP.
The steeper the Mn, the naturally more traffic goes to the server.
I cannot suggest free software for processing streams from IP cameras, but I can offer paid macroscop.
Pros
- video quality
- intelligent modules
- scalability is limited by ports in the router, well, it can be - a paid software license.
Cons
- rarely, but the router is "clogged".
- you can't save enough for the archive with hard ones
- the video can be recorded in fragments in the archive.
- server setup (OS, pick up a frame from each webmord to watch somewhere)
