DVR Digital Video Recorder

A DVR records CCTV video in digital format on a disk drive. Recordings can then be copied to a flash drive, SD memory card, network storage or local drive. DVRs use H.264 video compression and have high-resolution output connections such as HDMI and VGA. The recorder type must match the cameras, including analog CCTV cameras. DVRs form part of our CCTV systems.

You can adjust the recording resolution to store more days of footage. Simultaneous playback lets you review recordings from all cameras together. Motion detection identifies a change in an object's position relative to its surroundings, and in a DVR it allows recording only when motion is detected, which saves disk space. The features most buyers ask for are:

A hard disk stores and retrieves digital information using rigid, rapidly rotating disks, and it retains the data when the power is off. Capacity decides how long you can look back, with common sizes such as 500 GB and 1 TB. The number of days depends on how many cameras you have, their resolution, and whether they record all the time or only on motion. We calculate it for your site, so you know the answer before you buy, not after the day you need an old recording.

Playback lets you see what each camera recorded at a selected date and time. Open the playback menu, choose the required date and time, then select playback. Recorded footage can be copied using USB connections, including USB cables, flash drives and hard disk drives. We show you this at handover, because the moment you need a clip is the wrong time to learn how.

We supply, install and service recorder systems in Hyderabad and Visakhapatnam, India, as a complete job:

Builders and architects should plan a secure room or rack for the recorder, with ventilation and power backup. Industries and commercial building owners should size disks for the days of footage they must keep. Hospital owners should restrict access to recordings, because footage can include patients and staff. We set passwords, users and retention with your security head. MEP consultants can send the recorder schedule and we price it against the specification. Corporates should keep recorders in secure rooms with access logs. Defence establishments, including Navy and Army sites, need recordings kept securely, and we plan and quote within their security and vendor rules.
