How to choose the right video surveillance system?

Question

CCTV

Hello.
The dilemma is as follows:
* 6-8 analog cameras on the corners, a DVR, strobes, power supplies, and as a result, a mediocre picture. The issue price is 600-700 dollars
* 2 IP cameras, connection to an existing server. The asking price is about the same.
Now a little about the object: an apartment building, surrounded by a fence, the main purpose of the system: to monitor cars on the territory, territory.
In the case of analog cameras, install them densely and observe silhouettes; in the case of IP, install them at the level of 6-7 floors and believe that something can be seen. In both cases, it is planned to record to the media with subsequent access to the footage (http, samba). Write not constantly, but only on motion detection. (motion?)
The agony of choice. Thanks for the recommendation.

Answer 1

With IP cameras, the task is easier to solve, especially since they usually support PoE - less wires, less equipment.
If you take it with HD support, then the picture will be just great - you can see almost everything. True, it’s better not from the 6-7th floor, but lower all the same. There is a free ZoneMinder
for recording (including motion) / viewing .

Answer 2

I also think that it will be better with IP cameras.
Another good piece of advice was given by bskydive, I'll add to it:
1. AXIS are good cameras, although not budget ones. But I wonder if it happens at all when cheap and good?
2. ViewDesigner is a good tool for estimating the characteristics of optics, but it only supports cameras with 4 standard sensor formats. And if you have cameras with a sensor like 1 / 2.5 "or 1 / 3.6" then you can use a slightly more modern lens calculator: cctvlenscalculator.com or using the IP Video System Design Tool program, it is also even more visual than ViewDesigner and displays in 3D.
3. You can also estimate network traffic and disk space using this program.

Answer 3

Hello, this is the preliminary calculation:
Outdoor HIKVISION DS-2CD2032-I 150 2 300
Internal
HDD 2Tb 95 1 95 WD (WD20EZRX) 2000GB
Power supply 3A 32 1 32 Power supply 3A 12V
Wire Twisted pair 95 1 95 Bay 5e 305m oknet
Mounting 40 1 40 High-rise
Total 562 but these are only two outdoor cameras. I saw an article on Habré about a minicomputer to which you can connect a web camera and thus get an internal ip camera, is this an option or not?

Answer 4

I recommend using:
www.axis.com/ru/solutions/system/index.htm
1. Estimate the characteristics of optics:
www.dallmeier.com/en/products/tools/viewdesigner.html
2. choose a camera model from here:
www.axis .com/ru/products/video/selector/index.php
3. Set up a profile and specify the camera model
www.axis.com/ru/products/video/design_tool/v2
As a result, a good specification is obtained. Then you can search by price.
The main thing is to translate the requirements into lens characteristics. What will we distinguish on the monitor, from what distance, on what area (angles vert/horiz + min/max distance to the object), how much and what to store, where and how to transmit.

Answer 5

To organize a video surveillance system, I advise you to order a Zenith IP camera, namely the Zenith E5 model: www.techport.ru/katalog/products/kompjuternaja-teh... It will provide high resolution video images both day and night, as well as connection to networks and recording to a memory card.
