At the moment not sure what having additional cameras would do for HMS. Mostly they allow you to view the cams if you get any kind of alert. From my reading, the cameras really don’t add any functionality to HMS.
5 cams can be added to the HMS designated as “Security Cams”. This integrates the cams into the Home Monitoring Tab by allowing those 5 cams to be “Grouped” together as security cams outside of the Home tab device list for live streaming. It also provides an event viewing UI similar to that which is on the Doorbell cams across all 5 Security Cams. As @WildBill mentioned, there are additional Security Threat alerts, however these are redundant of the cam’s native notification capabilities and aren’t as detailed.
The Wyze Cam Pan V3 cannot currently be selected for addition as a Security Cam, nor can the Wyze Cam OG. The last cam to be added to the list was the Wyze Cam V3 Pro.
Currently the OG camera is not available to be assigned as a Home Monitoring Security Camera. Obviously, I didn’t purchase the cameras to just look around, but to create an alert that would in turn create an alarm when an intruder enters the home via breaking a window or other non-sensor vehicles.
Please make the Wyze OG camera compatible with the Wyze Home Monitoring system.
