Don't buy system. Bought system since automatic camera recording to Google Drive or Dropbox was advertised. When you get to the 'Allow" section of the setup in the app for Google Drive it says " App not authorized by Google yet ". Called ALC , they said they are and have been aware of the problem and that the developers in Taiwan are "working on it". So, they're selling these knowing that Google Drive and Dropbox do not work with it, aka unethical. There is no real tech support. The customer service reps want to help, it's just that they don't know anything technical with the system. Level II tech support is the same guy who just refers you back to the instruction manual, which isn't great. Testing the system several times, the camera fails to connect often. When it does connect, the video only saves to history some of the time. The keyfobs work about half the time. If you just want to view your house remotely with the camera, that's fine, but don't count on it actually recording, and it won't go to the 'cloud'. The door sensors work, the siren accessory is loud, the outlet plugs work fine. Motion sensors are ok but if you're home, you'll need to turn them off individually in the app since they're still active under "Disarm". If not, you will set them off walking around in your house. If they fix Google Drive, maybe I'll buy it again down the road , but this one is getting returned. Not waiting around for Taiwan to fix it someday . Good luck.
