Reliable Recording for Coax-Based Cameras
Professional CCTV DVR Recorders for Existing Security Systems
A CCTV DVR is the recording center of a compatible HD-over-coax security camera system. It receives video through BNC camera inputs, records footage to an internal surveillance hard drive and provides tools for live viewing, playback and video export.
DVR recorders are especially useful for properties that already have coaxial or Siamese camera wiring installed. When the cameras and wiring are compatible, replacing an older recorder can modernize the system without requiring every cable run to be replaced.
What Does a CCTV DVR Do?
A professional DVR combines camera recording, local storage, playback and supported remote access in one central device.

Preserve Compatible Wiring
Upgrade an Older CCTV DVR Without Rewiring the Property
Many older security systems already have coaxial cable running to useful camera locations. When the wiring remains in good condition, a compatible replacement DVR may allow you to retain those cable runs.
Depending on the age of the system, you may be able to replace only the recorder, or you may also need compatible HD or 4K CCTV cameras and additional hard-drive storage.
You may be able to retain:
✓ Existing coax cable runs
✓ Existing camera locations
✓ Compatible CCTV cameras
✓ Existing camera power wiring

Local Video Retention
How Much DVR Storage Do You Need?
Hard-drive capacity determines how much recorded footage your DVR can retain before the oldest recordings are overwritten.
More cameras, higher recording resolutions, continuous recording and longer retention periods require additional storage. Motion recording may extend retention depending on the amount of activity captured.
Storage depends on:
✓ Number of connected cameras
✓ Camera recording resolution
✓ Continuous or motion recording
✓ Required retention duration

A BNC connector alone does not guarantee compatibility. Camera signal, resolution and recorder support must also match.

Check Video Format and Resolution
Confirm whether your cameras use CVI, TVI, AHD or traditional analog video and verify that the replacement DVR supports the camera resolution.
Existing Installation
Inspect Cable, Connectors and Power
Existing coax may be reusable when it remains in suitable condition. BNC connectors, camera power supplies and cable distances should also be checked.
Should You Choose a DVR or an NVR?
The right recorder depends primarily on the camera technology and cabling used throughout the property.

Often yes, but compatibility depends on the cameras, video format, resolution and installed wiring. Confirm the existing equipment before ordering a replacement recorder.
