I have a total of three battery stick up cams . . . one of them will no longer let me access the live view using both the ring app or rapid ring app. Any motion events recorded by the camera are just black . . . signal strength RSSI -47 (good), and firmware up to date . . . it just spins at ‘Activating Device…’. With the Rapid Ring app it changes to ‘Establishing session…’ and then says my wifi network may be blocking live view. I have tried both on my wireless network and over cellular data. I’m having no issues with the other two cameras.
Most “Live View” issues are due to insufficient Wi-Fi. Either the cameras simply won’t connect to “Live View”, or they eventually do connect but display or record a black screen. Wi-Fi issues are frequently the cause of most video problems. Video requires a much higher Wi-Fi data-stream connection, unlike receiving Motion Notifications. And, even with a good (low) RSSI signal number, a strong signal connection doesn’t necessarily mean a good connection. If possible, temporarily move your malfunctioning cam close to your router to see if it will connect.
With a Poor (high #) RSSI signal strength number (displayed on “Device Health”) and if you cannot reduce the distance between your devices and router (to improve Wi-Fi reception), you may need a Wi-Fi ‘repeater’ device positioned about halfway between your devices and router. Additionally, the Ring Chime Pro has a repeater to help bridge the signal distance issues.
If you have a good RSSI, then you should concentrate your trouble-shooting efforts with your Wi-Fi router. Check out one of the relies from this link by @DragonDave
You could have multiple Wi-Fi devices competing with your camera for a good streaming connection. Here is an additional link to trouble-shoot the “Blackness” and it includes router adjustments:
And if your issues continue, you should call Ring Support by telephone:
Hopefully this might help you.
