I have had the Ring Spotlight Cam Battery installed for a while now and find it invaluable to keep check on an area of my garden.    It was easy to install, being battery, the light at night is bright so when viewing through the camera the majority of the details are seen.   Have yet to scare anyone or anything with the siren, but the siren is quite loud and should do the trick if needed.   My only gripe is that when I purchased I was not aware that it required two batteries.   It was lucky that I had purchased a spare battery to use with my two Ringdoorbell2.   As this light is generally installed at high level, it should be supplied with two batteries at order time.    Considering purchasing another one for another part of the property.   We shall see.
