MODEL SV-DVR4-N

SureVision 4-Channel 4K CCTV DVR with 4TB Storage

A compact DVR for four coax-connected cameras.

The SureVision SV-DVR4-N records up to four compatible BNC security cameras and includes a preinstalled 4TB surveillance hard drive. It is a practical replacement for a smaller coax-based CCTV system when the existing cameras, cable and power supplies are compatible.

4 BNC camera inputs

Supports compatible AHD, TVI, CVI and traditional CVBS cameras. Match each camera’s signal format and resolution to the recorder.

The published recording rates are 8MP / 4K at 8 fps, 5MP at 12 fps, 4MP at 15 fps, 1080p at 25 fps and 720p at 30 fps.

Storage and recording time

The included 4TB hard drive stores footage locally. A larger compatible drive can be selected for additional retention. Recording time depends on camera count, resolution, bitrate, frame rate and recording schedule.

Local recording and free remote viewing

Record and play back video locally without an internet connection. Use a properly configured internet connection for off-site phone or computer viewing. Standard local recording and supported remote viewing do not require a monthly cloud-storage subscription.

Is this the right recorder for your cameras?

Suitable for focused coverage at an entrance, small store, office or other property with up to four BNC camera connections. A BNC connection alone does not guarantee video or audio compatibility. This DVR does not provide PoE power for the coax cameras.

Is 4K HDMI output the same as 4K recording speed?

No. HDMI describes the signal sent to a monitor. The published 4K / 8MP recording rate is up to 8 fps; camera input formats and playback decoding have separate limits.
