DVR Security System Review

If you want to lean towards a top of the range DVR card, consider the Geovision GV 800 DVR card. The GV-800 enables you to install up to 16 cameras to your DVR security system or more if you opt to install more than one card. The GeoVision GV-800 is not the most outstanding DVR card on the market but it does handle the job of recording well. Video is recorded at a much higher frame rate than the cheaper DVR cards in the Geovision range but the system requirements don’t increase.

Video can be recorded at up to 120 FPS (frames per second) when recording in NTSC mode. As with other DVR cards the frame rate for the Geovision GV800 is divided equally between each camera you have attached to it, 16 cameras equals 7.5 FPS. This DVR capture card can process audio picked up by your surveillance system and it has four audio inputs. Many models of security camera are suitable to be attached to the GV 800, the majority of IP, night vision and other cameras can be set up easily.

There is a reasonable amount of software available for the GV800 and it is compatible with the ezCCTV surveillance software. You can also use the ‘GV-System’ software that is capable of controlling the cameras attached to your surveillance system. The software also includes a point of sale transaction overlay. It provides an instant playback feature, if you see something suspicious happen you can quickly watch the scene again. GV-System also has a timeline feature that can be used to view video footage recorded at a specific time, you can operate this feature through a graphical tool that represents a timeline.

GV-system also lets you tweak the level of motion detection in specific areas that are under surveillance. You do this through the ‘advanced motion detection’ feature that displays the output of a specified camera. By highlighting areas within the displayed output screen you can choose to ignore motion being picked up or set the system to trigger an alarm.

A quick warning to anyone considering the card that has a motherboard with a VIA chipset, such motherboards are incompatible with the GV-800.
