What is a DVR: Digital video recorder is recording device for recording video images form security cameras. on the inside of a DVR is very similar to a computer with circut boards and hard drive to record video images on for weeks or even months. the bigger the hard drive the more video recording you can keep. Almost all DVRs can be set up to automatically over write the old images which means after the hard drive is fully used up, the DVR automatically re-record over the oldest video recording . Therefore you don't need to worry about the DVR becoming full. Now a days the DVRs come with motion detection software installed so that you can set them up to record only when cameras detect motion in their field of view therefore you can record for much longer periods. Most DVRs come with possibilty of viewing through internet and Iphone, if you have other make of phone ask the supplier and make sure that the DVR is compatible with your particualr make phone.
There are new version of DVR which are HD capable, but unless you use HD CCTV cameras, high quality expensive cabling, ehich are quite pricy they are no difrent to ordinary DVRs. We have set them up and tested them but in all honesty we saw no diffrence in quality of picture with normal DVR.
Before you buy a DVR you must decide how many cameras you are going to install. as they come in 4 channels, 8 , 16 or even 32 channels. When deciding on number of cameras always think ahead and see if you might need to add extra cameras sometimes in the future. You be surprised to know how many times people buy a 4 channels DVR and after only a few month find out that the need more cameras and need to buy a bigger DVR. This is true specially in businesses.
Decide how many days recording you need
