Review on Wsdcam Wireless Door Alarm With Remote 2 Pack, Battery Included, 105 DB Loud Pool Door Alarm, Wireless Door Open Alarms Sensor For Kids Safety Home Security by Kevin Phillips

When I installed these, Ring mode worked fine, but if I tried to arm one, it went off immediately (because the other door was open). I needed these to function independently, but it was set up so that both remotes controlled both door sensors.If you want them separate, you have to delete all remotes from both sensors, then pair the appropriate remote to the matching sensor. There are other questions and reviews that detail how to delete and pair remotes, so I won't cover that detail in this review. But basically, remove a battery and put it back in while holding RING. Once it beeps a second time either hit PANIC to delete all remotes or ARM to add the remote.These were easy to install (just attach the double-sided tape and stick them up). Make sure to line up the arrows for the sensors. The remote is intuitive and easy to use.The alarm is sufficiently loud. I'm not sure it's 100+ decibels like it says, but it's loud. One slight annoyance is that it's fairly loud when you arm or disarm, too. I'd rather that be at a much lower level. Also, the Ring mode is a bit louder than I expected.There's no manual provided, so I had to rely on this page for instructions.Incredible value for the price.
