Let's divide the video surveillance installation process into main stages:
- Estimation of the cost of work and the location of CCTV cameras.
- Selecting the necessary equipment
- CCTV installation process
At the 1st stage you need to select a company, which will directly carry out the installation of the video surveillance system, a trade and installation company is best suited, since they will install the entire system and advise, what kind of equipment will be needed. A specialist’s visit to assess the cost of work and equipment in Kazan is usually free, however, outside the city it fluctuates around 500 rubles.
When choosing the necessary equipment for video surveillance systems, you, likely, provide 2 commercial offer option. One will be for an analog system (usually costs less) and the second one is digital(IP video surveillance). Of course, if you have the desire and opportunity, then you need to choose a digital system, because the picture looks high resolution, naturally, more colorful and clear.
Video surveillance installation must be produced by highly qualified employees, this will allow you to get maximum image quality. Often, when ordering a service: installation of video surveillance, the customer looks only at the cost of the work and chooses a lower cost. Unfortunately, many pseudo specialists are rather superficial about installation(set it and forget it) and do not take full advantage of the cameras.
For instance: It is not uncommon for cases when 8 street cameras used 1 power supply 2A(the picture at night will be bad). And the customer will be sure, that I bought a bad system. therefore, when choosing video surveillance in Kazan, contact only time-tested, trade and installation companies.
Now let's move on to the video surveillance installation itself.. Cable wiring - the cable in analog systems for outdoor wiring is painted black(example: CVC P-2E,75omg, street 2x0.75), внутри помещения – белый(example: KVK-V-1.5, 75omg, internal 2x0.5), для Ip – внутренний в сером исполнении, street in black. CCTV cameras from the DVR side, if the system is analog, connected by BNC connector(2 the wiring “goes” to the power supply (+ and -), on the camera side with a BNC connector and a DC power connector. If the camera has a varifacal lens(example 2.8-12mm) then you can set the required viewing radius(it is done manually).
When the CCTV installation is complete, You can set up remote viewing via PC, tablet and phone. Today, there are quite a large number of cloud services, who do it for free. Setting up remote viewing is described in sufficient detail in the DVR manual.
