GeoVision DVR Cards are one of the most advanced surveillance solutions on the market today having sold more DVR card products in the world than any other manufacturer in its class. The reason for GeoVision's popularity is due to its innovative product design, technical support, powerful features and free software upgrades. It is such a well designed, technically advanced but user friendly security solution that even prestigious institutions such as the FBI, NASA and US Coast Guard are using this product.

A Geovision  DVR card is a medium sized PCI card that is inserted into a vacant PCI slot on your motherboard which turns your PC into a fully featured professional surveillance system. Video from up to 16 cameras is recorded on your PC's hard disk based on user defined schedule or motion detection.

A built in webcam server allows users to access the live streaming video either over the internet or within an internal network.

You can also view the video live on an internet enabled cell phone. If you own a PDA phone such as XDA or a palm device that runs Windows CE or Microsoft Pocket PC, or a Nokia/ Sony Ericsson that runs on Symbian software, you can access the video anywhere around the world to check out your home or business.

The software also has a protective feature called "digital watermark" that will protect the video evidence with a permanent image to prove that it has not been tampered with. Multiple users can be granted access to the system, and user rights can be defined with different levels of capability, protected by issuing passwords

It is important to know that all models of Geovision cards share the same power features but only differ in the recording frame rates of FPS. The recording frame rate is divided by the number of CCTV cameras installed to get the effective frame rate per camera.

On the other hand, high end models such as GV-1120, GV-1240, GV-1480 Combo Cards have enhanced features such as 16 channel video / audio recording and real-time display .
