Hilook Digital video recorder (DVR) is an electronic device that records video in digital format on the disk drive, USB flash drive, SD memory card, SSD, or other local or network storage device. Human computers are often connected to video recording devices and used as DVRs; in such cases, the software used to record video is an integral part of the DVR. Many DVRs are classified as consumer electronics devices; such devices can also be called personal video recorders (PVRs).

Hilook Digital video recorder set up by physical security applications record video signals from lockable television cameras for detection and recording purposes. Many are designed to record audio as well. DVRs have evolved into rich devices and provide services beyond the simple recording of pre-made VCR video images. The DVR CCTV system provides a wide range of advanced functions in VCR technology including video search by event, time, date and camera.

There is also more control over quality and frame quality that allows the use of disk space to be configured and the DVR can also be set to record old security videos when the disk is full. In some DVR security systems remote access to PC videos, using a PC can also be achieved by connecting the DVR to a LAN network or the Internet. Some of the latest high-performance records include video analytics firmware, enabling functionality such as ‘virtual tripwire’ or discovery of discarded items on the scene.

Security DVRs can be categorized as PC-based or embedded. PC-based DVR architecture is a personal computer with video capture cards designed for video capture. The embedded version of the DVR is specially designed as a Hilook Digital video recorder with its software and application software contained in firmware or read-only memory.
