NVR Recorder 16CH 4K – Dahua

Description

This Dahua NVR is the one you fit when the installation is no longer four cameras: 16 channels, a screen split into 1, 4, 8, 9 or 16 images, and 4K output.

The interesting detail is one almost nobody checks: artificial intelligence costs it half its bandwidth. With AI off it takes 144 Mbps in and recording; with AI on, 72 Mbps. In plain terms: either you fill all 16 channels with ordinary cameras, or you use fewer cameras and get the analytics. That calculation belongs before the cameras are bought, not after.

• Perimeter protection on 4 channels (line crossing and intrusion) and SMD Plus on 4 channels, which filters out movement that is not a person or a vehicle.
• Records cameras of up to 12 MP and down to D1: it lives with old and new equipment side by side.
• Smart H.265+ to stretch the days of footage on the same disk.
• Two USB 2.0 ports and a full protocol set (HTTPS, P2P, DDNS, IP filter) for access from outside.
• Under 10 W without disks, in a 260 × 232 × 47.6 mm chassis weighing 850 g.

It runs on an external 12 V supply and the disks are not included. Tell us how many cameras, at what resolution and how many days you want to keep, and we will tell you the exact disk — and fit the lot if you want.

Who it’s for and who it’s not for. This is the recorder for an installation that can no longer fit within four channels: businesses, communities, or a property with multiple access points. It’s not for a house with two cameras: the 16 channels and bandwidth are paid for but will remain unused. It’s also not a turnkey solution, as the hard drives are not included.

Frequently Asked Questions

Are the hard drives included?
No. The recorder is powered by an external 12 V source, and storage is chosen separately, depending on how many cameras, at what resolution, and how many days of footage you want to keep.

Can 16 cameras of 8 MP be connected to this recorder?
What matters is the bandwidth, not the number of connectors: 144 Mbps input and recording with AI off, and 72 Mbps with AI on. This calculation is done before purchasing the cameras.

Does the analytics work on all 16 channels at once?
No: perimeter protection (line crossing and intrusion) and SMD Plus work on 4 channels. They are distributed where they are really needed, usually at the access points.
