When organizing home video surveillance, records need to be stored somewhere, so that later it is possible to view them. Such a device is usually a computer with special software or a DVR.
All cameras are connected to it. Inside the recorder, a hard disk is installed, to which recording is performed.
A DVR is actually a compact computer with specialized software preinstalled on it.
The registrar allows not only to store and view records, but also provides the ability to connect to the system remotely. The scheme is simple: the registrar connects to the router, after which you can watch video via iphone, or any other gadget. A free program for remote access is installed on the phone. As a result, you get the opportunity to watch your cameras, being anywhere in the world - if only there was an Internet network.
An important question is how much records should be stored, how deep the archive should be. The volume of the hard disk depends on this, and accordingly, its cost. Usually records are stored no more than 2-3 weeks. This is the maximum time for the absence of the owners in the house. As a rule, all unpleasant events become known immediately, and a large archive depth is not required. It is advisable to set the capacity of the hard drive so that it lasts for 2-3 weeks.
How to increase the storage time of videos? For this, it is best to organize timelapse and motion recording.
