DVR Security System Review

Frame rate is an age-old problem for people who have an abundance of cameras connected to their PC based security system. Standard televisions typical display images at 30 FPS (frames per second), a speed that most of us consider smooth. At 30 FPS images displayed are smooth in that you don’t notice any jumpiness in what you are viewing. The GeoVision GV1480 DVR card enables you to connect multiple surveillance cameras to your security system while delivering a high frame rate.

A DVR cards frame rate is split evenly between each surveillance camera connected to it. When 16 security cameras are attached to a DVR card capable of producing 120 fps each camera records images at 7.5 FPS. At 7 FPS video recorded by your surveillance system will be choppy, The GeoVision GV1480 DVR card can record video at 480 FPS. If you are building a PC based surveillance system from the ground up, the GV1480 is worth considering. Each camera you connect to your system will have the foundation it needs to deliver smooth video as well as audio.

You will need a fairly decent PC to install and use the card effectively, dual core PC’s are quite reasonably priced now but that may be overkill. Your minimum CPU needs to be a 2.8 GHz Pentium and you need at least 512 MB of RAM and a 250 GB hard drive. The GeoVision GV1480 uses Wavelet and MPEG4 video compression; it also has advanced motion detection capabilities. You can set the card to record as soon as your surveillance cameras detect motion or set it to record when objects detected move to specific zones.

You have the option to view the output from the card on either your PC monitor or your television as it has a TV output. You can attach two or more of these DVR cards to your surveillance system to increase its capacity for surveillance cameras. The GeoVision GV1480 has full D1, Half D1 and CIF video resolutions. The card includes the software necessary for accessing your surveillance cameras over the Internet and is fully network compatible. As with many of the DVR cards in the GeoVision range the GV1480 is incompatible with motherboards using the VIA chipset.
