FAQ — Security Camera Recorder (CCTV DVR)

What’s the difference between a DVR and an NVR?

A DVR records video from coax-based cameras (HD-over-Coax/analog) and is ideal when you want to keep existing cable runs. An NVR records from IP (network) cameras over Ethernet. If you already have coax, a DVR is usually the most cost-effective path to 4K.

Will this DVR work with my existing analog cameras?

Yes. It’s backwards compatible with legacy analog (CVBS) and supports HD-over-Coax formats (TVI/CVI/AHD), so you can mix cameras on the same recorder.

How much storage time will the 2TB hard drive provide?

Retention depends on resolution, frame rate, and recording mode. Many users get 2–4+ weeks using motion/AI recording. You can expand storage or tune settings for longer retention.

Do I need a subscription for remote viewing?

No. Remote apps for iOS/Android/PC are included. View live, playback recordings, and receive alerts without monthly fees.

Can I export video clips for police or insurance?

Yes. Use Smart Playback to jump to events and export MP4 clips or snapshots to a USB drive with time/date stamps.

Is installation complicated?

Most installs are plug-and-play on existing coax (RG59/RG6). Our U.S. team provides lifetime support if you need help.
