Question

Not sure how the dvr works but need to know how much space it should have and how it works with the camera's. also, if i can view the video on the tv each day and delete video so that it doesn't waste space.

Answer 1

There are hundreds of different types of digital video recorders (DVR's) out there so it is hard to answer your question very specifically.

DVRs take the video signal from cameras and record them on a hard disk drive just like your computer uses. Some DVRs are stand-alone "boxes", others consist of a plug-in board and software that allows any standard computer to work as a DVR.

DVRs generally come in models that will handle 4, 8, or 16 cameras. The amount of time that you can store images from the cameras depends on several factors, including size of the DVRs hard disk, the resolution and frame rates that you are recording at, and the amount of movement that takes place in front of each of your cameras.

Figuring out exactly how much time you can record on your DVR can be calculated fairly precisely, but it is too complicated to explain in this forum. However, it is fairly safe to say that any DVR that you purchase will probably hold several days or even weeks worth of recordings before it begins to run out of space.

Yes, you can view images and then delete them when you are through to save space. In addition, most DVRs will automatically record over the old images when the disk gets full, so you always have the latest images available.

They are a major online seller of security camera equipment and should have a good selection of DVRs for you to look at.
