Geovision GV-DVI-E52 DVI Audio/Video Interface Card
Overview
The Geovision GV-DVI-E52 is a DVI-type expansion interface card that adds four independent channels of video input and audio I/O to compatible Geovision recording systems. This card conditions analog or composite video signals and audio streams into a format your DVR or NVR can ingest, making it a straightforward expansion path when you need to integrate additional surveillance sources without replacing your core platform. Typical deployments include retrofit installations where existing analog cameras or auxiliary video feeds must coexist with a Geovision digital backbone.
Compatibility
The GV-DVI-E52 integrates with Geovision DVR and NVR systems that support DVI-type expansion modules. Confirm your recorder's manual or contact the manufacturer to verify slot availability and firmware compatibility before ordering. The card supports simultaneous multi-channel capture across the four independent video and audio pairs, and works with mixed-format surveillance configurations where analog and digital sources run in parallel.
Installation Notes
Install the GV-DVI-E52 into an available DVI expansion slot on your Geovision recorder. Route video and audio connectors (typically RCA or 3.5mm depending on your source equipment) to the card's input terminals. No separate power supply is required—the card draws power from the host recorder's backplane. Secure the card bracket to the chassis to prevent vibration-induced loosening during operation. Refer to your recorder's installation guide for slot-specific mounting detail and any firmware updates required to enable the new channels in your VMS software.
