Digital Video Recorder (DVR)
A DVR is what views, records, stores and manages the footage from your cameras. Channel count is the thing to get right: a 4-channel unit takes four cameras, and the range runs 4, 8, 16, 32 and 64.
What You Get
- Units from 4 channels to 64.
- Full HD recording for image and video quality.
- View, record, store and manage footage in one place.
- Sized to the cameras you have now, with room to add more.
- Supplied and configured with the system, not sold on its own.
DVR Or NVR
A DVR takes analogue and HD-over-coax cameras on a direct cable run to the recorder. An NVR takes IP cameras over your network. The recorder therefore follows from the cameras rather than the other way round.
The practical reason to choose a DVR is existing cabling. If a premises already has coax to each camera position, a DVR reuses every run, and replacing that cabling to move to IP is usually the most expensive part of the job. New installations more often go IP, but there is nothing wrong with a DVR system that suits the building it is in.
How Long It Keeps Footage
Recording time depends on the hard disk fitted, the number of cameras, the resolution and whether the unit records continuously or only on motion. As a rough guide, a 2 TB disk holds somewhere between two and four weeks from a four-camera Full HD system recording around the clock.
Motion-triggered recording stretches that considerably, because a camera watching a quiet storeroom writes almost nothing overnight. When the disk fills the oldest footage is overwritten first, so the system keeps running without anyone having to manage it.
Installed Across Sonipat
We supply DVRs as part of a working system rather than as a box on its own, sized to the cameras you have now with channels spare for the ones you add later. Installations across Sonipat and Haryana are configured on site, including remote viewing, and we set the retention period with you rather than leaving it at the factory default.
Common Questions
How long does a DVR keep recordings?
Between two and four weeks is typical for a four-camera Full HD system on a 2 TB disk recording continuously. Recording only on motion extends it well beyond that. A larger disk buys proportionally more, and we size it to the retention period you actually need.
Will a DVR work with my existing cameras?
If your cameras are analogue or HD-over-coax, yes, and the existing cable runs can usually be reused. IP cameras need an NVR instead. We check what is already installed during the survey and tell you which way round it should go.
Can I see DVR footage when I am away?
Yes. Once the DVR is on your internet connection you can view live and recorded footage from a phone or a computer anywhere. We configure and test that as part of the installation.
