Hybrid DVR Systems for Existing Coax Security Cameras

Upgrade an older CCTV system without replacing every cable run. SVD hybrid DVRs support common 5-in-1 security camera formats — HD-TVI, AHD, CVI, CVBS analog, and IP — so installers can keep existing BNC/coax wiring, replace a failing recorder, and add newer cameras over time.

Choose 4-channel, 8-channel, or 16-channel DVR models based on the number of cameras on the job. Hard drive options vary by model, including no HDD for installers supplying their own compatible SATA surveillance drive, plus pre-installed storage options for ready-to-record systems.

Not sure whether the job needs a DVR or NVR? Start with our installer guide, or compare channel count and storage needs before choosing a recorder.
