GW Security Inc. GW7816NP 16 Channel 4K NVR Kit 4TB HDD 16 x 8MP Varifocal Bullet Cameras

Complete 4K Surveillance Kit

The GW Security GW7816NP kit delivers a 16-channel NVR with a pre-installed 4TB hard drive and sixteen 8MP bullet cameras. Each camera captures 3840 x 2160 resolution at up to 30 frames per second across all channels. The system targets homeowners and small businesses that need continuous, high-detail coverage without assembling components separately.

PoE Wiring and Lens Constraints

Cameras connect through sixteen PoE ports on the NVR using the supplied 60-foot and 100-foot Ethernet cables, limiting placement to those distances unless additional cabling is sourced. The 2.8-12mm varifocal lens adjusts manually from a 115-degree wide view down to a 22-degree narrow view, so the field of view is fixed once installed. Night vision relies on eighteen SMD LEDs rated for 120 feet of infrared range.

Upgrade From Basic 1080P Systems

This kit replaces older 1080p or 720p recorders that lack H.265+ compression and AI human detection, reducing storage consumption and false alerts. The jump is worthwhile when identifiable facial detail at distance or colour night footage is required. Buyers who need more than sixteen cameras or built-in spotlight illumination should consider larger or differently equipped platforms.
