Review on 📷 Swann Wired PIR Bullet Security Camera, 4K Ultra HD Surveillance Cam with Color Night Vision, Indoor/Outdoor, Thermal, Heat & Motion Sensing, Audio Monitoring, Compatible with NVR via PoE, SWNHD-885MSB+ by Kelly Noonan

I bought another system and got false positives. The combination of PIR and Swann motion detection system is much better. However, the Swann system is 4 times more expensive. Most importantly, cameras can choose which part of the field of view is involved in motion detection. Crate; I was convinced that both my cameras' motion detection wasn't working, but it turned out that one of those cameras was set to default and had the entire field of view set to NOT react to movement. The other two cameras had selected their entire field of view to react to movement. However, no matter how hard I tried, one of the four cameras did not work properly and I had to send it back.
