A 4-channel DVR (digital video recorder) records up to four cameras. This range has nine models, from 1080p up to 8MP (4K).
How to choose
- Resolution. Models are 1080p, 4MP Lite, 5MP, 5MP Lite or 8MP. Higher resolution gives finer detail, but the cameras must match the recorder to use it.
- Camera format. The ANNKE D941BB is 5-in-1. The Prolux PXD-8204-HYK4MP is a hybrid. The Dahua XVR5104HS-I3 is penta-brid. These are built to accept more than one camera type, which suits reuse of existing cameras and cabling.
- Power over coax. The Hikvision 8MP PoC DVR is a PoC (power over coax) model. It is designed to power compatible cameras through the coaxial cable.
- Smart features. Several Hikvision models carry AcuSense. The Dahua XVR5104HS-I3 is WizSense with AI.
- Format and compression. Six models list H.265, a compression method that reduces storage per recording. The Hikvision models are 1U, a slim rack-height case.
You will also need a hard drive, sized to your camera count and the days of footage you want to keep.
