Digital video surveillance system. Expensive but nice



An article based on the construction of an analog video surveillance system by non-professionals .
Continuation of this article: Digital Video Surveillance System 2. DVR, software and load testing

Objective : equip the service station with a video surveillance system. Access to live-image from multiple jobs. It is desirable to have access to the cameras via a smartphone (for control in cases of travel).
')
Note: the entire system was introduced during the construction of service stations. In addition to video surveillance, users' workstations, servers, equipment for automation, etc. were installed. But let us dwell only on the part about the video.

I do not even know what motivated me to stay on the figure. Maybe the budget allowed, maybe I wanted to try a new one. In any case, it was quite a useful experience and now the advantages and disadvantages of an analog / digital system are visible.

When choosing equipment, there was a great desire to buy everything centrally. It is always easier to work with one large supplier than with a dozen small ones. Three weeks of searching, comparisons, correspondence with vendors, torsion of the nose on the size of the discount. In the end, we stopped at the online store shop.nag.ru. Perhaps it was not quite the right approach and it was necessary to spend more time choosing suppliers, ordering test equipment. But the dates began to tighten, the customer lyutoval and we stopped at NAG.

Note: all cameras and switching equipment with PoE function. I wanted to get rid of a heap of unnecessary wires, power supplies and junction boxes. Aesthetics is a guarantee of quality and beautiful work.

Nomenclature:
1) Cameras are external. To control the outer perimeter of the service station.
Camera requirement:
- Image quality, since the camera control distance is about 100 meters.
- Workmanship with regards to the strength of the case. Winds up to 70 m / s in the order of things.

Winner in the category IP camera POWERTONE street 2.0Mp, WDR, with IR illumination, 3.3-12mm, PoE, with a bracket

unboxing:






Camera cables come out of the bracket. You can mount "flush" and all the wiring to put under the skin. It is not required to leave anti-droplet loops. (+10 to aesthetics)

2) Internal cameras. Office part.
Camera requirements:
- IR illumination. Lighting of rooms and corridors on motion sensors. At night, on the timer, 90% of the interior lighting is turned off.
- Installation to the ceiling type "Armstrong".

The choice fell on the IP camera SNR dome 3.0Mp with IR illumination, 3.3-12mm, PoE, vandal proof

unboxing:






The setup process:


But I advise you to take not such "cool" cameras (they are more suitable for large and open spaces. A warehouse or open-air office will do). For small office spaces and corridors, Beward B1062DX (2000 rubles cheaper) or Chinese counterparts is enough.

3) Internal cameras. Repair area.
Camera requirements:
- Installation on the wall.
- IR illumination.

IP Camera POWERTONE street 1.3Mp with IR illumination, WDR, PoE, 2.8mm

unboxing:






The setup process:


An ordinary camera. Connectors are inconveniently located, for isolation it is necessary to use heat shrinkage. (-10 to aesthetics)

Aggregation equipment.

4) Access switch for cameras.
Requirements:
- PoE support.
- Managed L2 switch.
- At least one 1000Base-T / SFP port.

Our applicant Switch SNR-S2940-8G-PoE , own production NAGa.
Switch running Cisco like cli, which pleased. (thanks to cagami for fixing)

unboxing:






There is an SFP port if you need to place a switch further than 100 meters from the server.

Note: the switch is noisy decently, in the process of setting 4 switches worked at the same time, the head begins to ache within 5 minutes.

5) Distribution switch (core).
- Support for all VLANs, DHCP Relay, etc.
- Availability of SFP ports.

Cisco SG300-52 <SRW2048-K9-EU> Managed Switch (50UTP 10/100 / 1000Mbps + 2Combo 1000BASE-T / SFP) . This is not ideal, but a budget is suitable for the required characteristics.

unboxing:




6) Video server / DVR.
Requirements:
- Rack mount.
- Installing a large number of HDD.
- Support for different CCTV cameras.

NAG again saves us with its DVR. Video recorder network SNR up to 16 IP cameras. D1 / 400fps, 720p / 200fps, 1080p / 100fps, 8HDD . Unfortunately, there are no unbox photos, but the package is on the website.

6.1) HDD for DVR.
Requirements as such were not. We stumbled upon the HDD 4Tb SATA 6Gb / s Seagate Video 3.5 3.5 "5900rpm 64Mb , according to Seagate's assurances, it was created just for archival storage of video. It stopped there.

To build a video surveillance system it took:

1) Cameras are external. x 10 pcs.
2) Internal cameras. Office part. x 12 pcs.
3) Internal cameras. Repair area. x 19 pcs.
4) Access switch for cameras. x 6 pcs.
5) Distribution switch. x 1 pc
6) DVR. x 3 pcs.
7) HDD for the DVR. x 6 pcs.

Solution price: 535,000 rubles.

Expensive happened. Although I am not going to be able to calculate right away how much the analog system will be on analog cameras.
But the advantages of this system can be recorded scalability, excellent image quality, aesthetically more pleasant.

By choice of the hardware part, that's all. Outside the article, work remained on the calculation of bandwidth for switches, setting up cameras and video recorders, setting up software for security posts. If this topic is of interest, I can write a small article with screenshots of software and give a couple of tips on what you should pay attention to before buying cameras and video servers.

I hope you liked the article. Do not judge strictly, this is my first experience. With errors as usual in PM.
