NVR & DVR Systems — Buy Online India at Best Price
Buy DVR and NVR CCTV recorders online India. Hikvision, Dahua 4-channel to 32-channel DVR/NVR at best price. H.265+ compression, remote access included.
The DVR (Digital Video Recorder) or NVR (Network Video Recorder) is the brain of your CCTV system — it receives video from all cameras, records to the hard disk, and enables remote viewing via smartphone apps. Choosing the right recorder for your camera count and required features is as important as choosing the right cameras.
DVRs are used with HD analog cameras (connected via coaxial cable). They are the most common type in India, offering 4, 8, 16, and 32 channel options. Modern Hikvision and Dahua DVRs support HD analog cameras up to 8MP (4K), H.265+ compression for efficient storage, and full remote access via the Hik-Connect or DMSS mobile apps.
NVRs are used with IP cameras (connected via ethernet cable). PoE NVRs (Power over Ethernet) are particularly convenient — they power IP cameras through the same ethernet cable that carries video, eliminating separate power supplies. NVRs generally offer more advanced features like AI-based analytics, face detection, and license plate recognition at a premium.
For home users in Kottayam, 4-channel Hikvision or Dahua DVRs are the most popular choice — they support up to 4 cameras with H.265+ recording at up to 8MP resolution. The Hikvision 4-Channel DVR includes built-in remote access, motion detection, and supports up to 8TB storage — enough for weeks of continuous recording at HD quality.
For businesses with higher camera counts, 8-channel and 16-channel DVRs offer significant storage and bandwidth. All our recommended DVRs support HDMI output for direct monitor connection, USB for backup and firmware updates, and ethernet for network connectivity.
Hard disk selection is critical — always use surveillance-grade HDDs like Seagate SkyHawk or WD Purple. These are designed for 24/7 read-write cycles and last significantly longer than consumer drives in CCTV applications. CCTVPROS stocks and installs genuine Seagate SkyHawk drives with all our DVR/NVR systems.

NVR & DVR Systems — Frequently Asked Questions
What is the difference between DVR and NVR?+
DVRs work with HD analog cameras using coaxial cable. NVRs work with IP cameras using ethernet cable. DVRs are more economical for new installations; NVRs are preferred for large systems and when using PoE cameras.
How many channels DVR do I need?+
Choose your DVR channel count to match your camera count, with some room for expansion. For 4 cameras, a 4-channel DVR works. For 6–8 cameras, an 8-channel DVR is recommended. It's difficult to expand beyond a DVR's channel limit later.
How long does a 1TB HDD last in a CCTV DVR?+
With H.265+ compression, a 1TB HDD stores approximately 15–30 days of footage from 4 cameras recording continuously at 4MP. Higher resolution or more cameras reduces this. 2TB is recommended for comfortable 30-day retention with 4MP cameras.
Can I view DVR recordings on my phone?+
Yes! Hikvision DVRs use the Hik-Connect app; Dahua DVRs use DMSS. Both provide live view and playback of recorded footage from anywhere with an internet connection. CCTVPROS sets up remote access during installation.
