A digital video recorder (DVR) or personal video recorder (PVR) is a device that records video in a digital format to a hard disk drive or other medium. It has also become the main way for CCTV companies to record their surveillance, as it provides far longer recording times than the previously used VCRs.

Protech Systems supply and install high end DVR's which record video onto hard disk drives and have the ability for Remote Monitoring over the internet. DVR's are supplied in a range of 4, 8 and 16 channels dependent on the amount of cameras required on the system. They have the ability of motion recording, time lapse recording and scheduled recording. Recordings onto the system can be viewed and downloaded onto memory stick or by the inbuilt CD writer.

Digital video recording times vary and are dependent on the size of hard drive storage and the amount of cameras on the system and whether the recording is set on motion or continuous recording.
