What is the role of a DVR in a commercial CCTV system?
A DVR (Digital Video Recorder) is the central hub of an analog CCTV system. It records footage from connected security cameras, stores the relevant data on a hard drive, and allows for playback, backup, and remote monitoring. In commercial setups, DVRs are essential for several practical and legal reasons such as security related surveillance, incident reviews, and compliance, as well as providing evidence for legal use.
How many cameras can a DVR support for commercial use?
Commercial DVRs typically support anywhere between 4 and 32 channels. At Videcon we stock 4, 8, 16 and 32 - channel recorders, giving you maximum flexibility no matter the size of your setup. The number of channels you need depends on the size of the property and the coverage required, with larger structures typically needing 16 channel coverage or greater.
What storage capacity is recommended for commercial DVR systems?
It’s generally recommended to choose DVRs with at least 2 to 4TB of storage or more, depending on the number of cameras, recording quality (e.g. 1080p vs 4K), and how many days of footage are needed for retention. Video files take up a large amount of space, so if you need to store large amounts we would recommend erring on the side of caution especially if data deletion is not an option. Many DVRs however do allow internal storage upgrades or external hard drive expansion to allow an appropriate amount of data to be stored.
What’s the difference between a DVR and an NVR for commercial surveillance?
DVRs work with analog cameras, while NVRs (Network Video Recorders) are used with IP cameras over network cables. DVRs tend to be more cost-effective for upgrading existing analog systems and are often cheaper generally, while NVRs offer more flexibility, resolution, and scalability for new installations.
