Pros & Cons

Pros

  • ✓ Four dual-lens cameras produce 8 simultaneous views at the cost of a 4-camera kit
  • ✓ 16CH 4K NVR expands to 16 cameras and 32 views without swapping the recorder

  • ✓ 1TB HDD included for months of local recording with no required subscription

Cons

  • ✗ 1300ft (400m) range is line-of-sight only; walls cut it to hundreds of feet
  • ✗ Turning on AI tracking commits the PTZ lens, giving up the second fixed angle
  • ✗ 1TB fills quickly with eight 4K views recording 24/7; cloud storage is optional
  • ✗ Local setup and viewing need a monitor for the NVR, which you supply yourself
