What is a DVR? Complete digital video recorder guide
7 min read
A DVR (Digital Video Recorder) is the hub of analogue CCTV systems. It accepts HDCVI, AHD or CVBS feeds, digitises them and writes the footage to hard disk.
When a DVR is the better choice
- Existing coaxial cabling is already in place
- Budget is tighter than a full IP stack
- A modest channel count (4–16) covers a home or shop
Buying tips
Check input/output resolution, HDD bays, mobile app support (e.g. DMSS) and whether a few IP cameras can be added. Our team can help you pick the right model in store.
