SureVision 4 Channel Digital Video Recorder — SV-DVR4-N

A professional digital video recorder (DVR) is the heart of a dependable HD-over-coax surveillance system, and this 4 channel DVR is designed for buyers who want real performance instead of consumer shortcuts. It records video from compatible HD CCTV cameras, supports multiple signal formats, and gives you the kind of reliable wired infrastructure serious homes and businesses expect.

This 4 channel digital video recorder is ideal for homes, small offices, storefronts, garages, and other compact properties that want professional video recording without the complexity of a larger enterprise chassis. Pair it with compatible HD over coax cameras for a premium surveillance platform built for 24/7 recording, remote access, and long-term ownership without monthly subscription fees.

4 BNC Inputs for Simple Wired Camera Connections

With four BNC camera inputs, this recorder connects directly to up to four compatible wired security cameras. That makes it an excellent fit for coax-based upgrades where buyers want to keep existing Siamese or BNC cable runs while improving video quality and recording features.

4K HDMI Output, H.265 Compression, and Smooth Playback

The SV-DVR4-N supports up to 4K HDMI video output along with H.265 and H.264 compression for efficient storage. It records up to 8MP Lite / 5MP / 4MP / 1080P / 720P resolutions depending on camera type, and provides clear local viewing through HDMI, VGA, and BNC display outputs.

Remote Viewing, Motion Alerts, and No Monthly Fees

This DVR includes free remote viewing tools so you can watch live video, review playback, and receive motion-triggered notifications from your phone, tablet, or computer. There are no recurring cloud fees required just to access your own recorder, giving owners full control over their footage and long-term costs.

Flexible Multi-Format Camera Support

This recorder supports AHD, TVI, CVI, CVBS, and IP camera inputs, making it a flexible choice for upgrades and mixed-camera environments. It also supports one-way audio over coax on supported TVI cameras and smart features such as motion detection, intrusion detection, cross-line detection, and face detection on supported channels.

Built for the CCTV Security Pros Ecosystem

This recorder fits naturally into the broader CCTV Security Pros ecosystem. Browse HD over coax cameras, compare the full CCTV DVR lineup, or shop complete HD over coax security camera systems if you want a professionally matched recorder-and-camera package. It is a practical foundation for buyers who want cameras, recording, playback, and remote access working together in one wired platform.
