GW Security Inc. 16 Channel 5MP NVR Surveillance Security System (4TB) GW4216EP

16-Channel 5MP PoE Security Kit

This GW Security system delivers a complete 16-channel surveillance kit with a 4K NVR and sixteen 5MP dome cameras. Each camera connects through a single PoE cable that supplies both power and data, simplifying installation across a property. The included 4TB hard drive begins recording immediately, and H.265 compression extends storage efficiency. The package suits homeowners or small-business owners who want an all-in-one, plug-and-play security solution.

Best for fixed-position monitoring with audio

The kit fits users who need continuous, scheduled or motion-triggered recording on every channel at up to 4K resolution. Built-in microphones on each camera add audio context to events, while smart person detection reduces false alerts. Buyers who require wireless cameras, battery operation or more than sixteen channels should consider other options. The fixed 3.6mm lens also limits the field of view compared with varifocal alternatives.

4TB pre-installed storage capacity

The NVR ships with a 4TB hard drive already installed, providing the baseline recording capacity for sixteen 5MP streams. H.265 HEVC compression helps maximise the number of retention days before overwrite occurs. If longer archival periods or higher-bitrate 4K recording across all channels are essential, additional drive bays or larger drives would be required.
