Very Satisfied with this Product
Everything working well, been using for several months now.
I have SIM card installed and Wifi connection, you can have it dial numbers and say a recorded (you make the recording) message or text through the SIM card. With just wifi connection it will send you push notifications to the App. I've had no problem getting either. I use the app for arming/disarming, checking settings, etc. The IOS APP has been working perfect for me, and other family member's Iphone.
The remote controls are a Con for me, because you can accidentally push a button. I've found some 433 mhz remotes that I think will work with this system, that have a sliding cover to protect the buttons from accidental pressing.
Another Con, is no extra HAMA sensors that you can buy. Yes I purchased some other HOSA sensors, and these work fine with the system. But I do like the HAMA door/window contacts with the extended capacity batteries.
The siren is not very loud, i'm using a HOSA wired speaker, and also on another floor, the HOSA wireless siren. This makes it much louder, the wired siren, is pretty good.
I'm very satisfied with it, especially combining with more HOSA sensors, gives me pretty good peace of mind. I've also got HOSA flood detectors, which is an nice addition for the basement.
I plan to install another for family member later this year.
