DVR card

The DVR card from Shenzhen Yishi Electronic Technology Development Co., Ltd is a hardware component designed for video recording and management in surveillance systems. It supports up to 16 channels of simultaneous video input and enables recording at resolutions up to 1080p. The card integrates motion detection and remote viewing functions, allowing users to monitor feeds via network-connected devices. It is compatible with standard DVR systems using common operating environments such as Windows and Linux-based platforms.

This card uses industry-standard compression formats including H.264 and MJPEG to balance storage efficiency and image clarity. The circuitry is built for continuous 24/7 operation under typical industrial temperature ranges of 0°C to 55°C. Most units are housed in shielded enclosures to reduce electromagnetic interference, a common requirement in commercial installations. The card does not include onboard storage; it relies on external hard drives connected via SATA or eSATA interfaces, which must be selected separately based on recording duration needs.

Primary buyers include security system integrators, retail chain operators, and transportation logistics firms that require centralized video monitoring. The product is typically ordered in batches of 10 or more units for deployment across multiple locations. Packaging is in anti-static blister packs with foam inserts to prevent physical damage during transit. Trade terms offered include FOB Shenzhen and CIF destination ports, with lead times of 7 to 14 days after payment confirmation. Buyers should verify compatibility with their existing DVR chassis before ordering.
