XVR-3108AD 8CH 4K Hybrid CCTV DVR 8MP XVR Powered By Dahua

The XVR-3108AD-4K is an 8-channel hybrid DVR that lets you mix old and new cameras on one recorder. If you've got existing analogue cameras and want to add higher-resolution ones later, this is the sort of box that avoids a full rip-and-replace.

What it actually does

• Records up to 8 channels, each accepting resolutions up to 8MP (4K).
• Works as a "hybrid" recorder — meaning it accepts HD-TVI, AHD, CVI, CVBS (analogue) and IP cameras on the same unit, so you're not locked into one camera type.
• Uses H.265+ compression, a newer encoding standard that keeps file sizes down so your hard drive lasts longer before footage gets overwritten.

Before you buy — check these

• Storage: it takes one SATA hard drive, fitted separately — the DVR itself doesn't include one, so budget for a surveillance-rated HDD sized to how long you want to keep footage.
• Monitor connection: outputs via HDMI or VGA, so confirm your screen has one of these inputs.
• Remote viewing: supported through a mobile app and PC software, useful if you want to check cameras while away from the property.

It suits typical residential setups, shops, warehouses and offices — anywhere you need a straightforward multi-camera recorder rather than a fully networked IP system.
