Video surveillance systems are increasingly entering our lives. The installed video camera significantly increases security: attackers prefer to "work" where there are no video surveillance systems. Before those who decided to acquire a video monitoring system, there is a choice - which system to choose?
Instructions
Step 1
To begin with, clearly define what purposes the installed video surveillance system should serve, what exactly it should do. The correct definition of tasks will allow you to choose the most suitable system and, in some cases, save on costs. Considering that in reputable companies the design and installation of such systems is carried out by specialized firms, we will consider the simplest option - the choice of a video monitoring system for private households.
Step 2
A good video surveillance system should protect your home from all directions, leaving no blind spots. At the same time, the number of installed video cameras should be the minimum required, they should not duplicate each other. Video cameras installed along the perimeter of the household should be quite clearly visible - in this case, their very presence will perform a protective function. When planning the purchase of video cameras, carefully plan their number and location.
Step 3
Surveillance cameras are divided into indoor and outdoor. The latter must withstand high humidity and temperature changes, therefore, they are more expensive than those installed indoors. The best camcorders can work even in complete darkness. Indoor video cameras can be installed discreetly, for this, models with a very small lens are used.
Step 4
The most important component of a video surveillance system is a video recorder. In the simplest version, its functions are taken over by an ordinary computer, the information received from the video cameras is recorded on the hard disk. A more expensive and complex option involves installing a separate DVR - it has several large hard drives, is resistant to computer failures and power outages.
Step 5
In the most difficult cases, a video server is used - thanks to an Internet connection, the owner has the opportunity to view the picture coming from the video cameras, being thousands of kilometers from home. The video server also takes over many other security tasks: for example, security and fire alarm lines can be connected to it. The functions of a video server, in a simplified version, can be taken over by an ordinary home computer.
Step 6
Even a fully assembled video surveillance system cannot work without specialized software. In order to avoid problems with software compatibility when setting up the system, buy the entire set of hardware and software from one specialized company. In this case, you simplify the setup process and can count on warranty and post-warranty service.
