This professional monitoring plan is the cheapest among the systems we tested, tied with SimpliSafe. For cellular backup, you need to buy a modem that plugs into the Smart Hub. The keypad in the Security Pack has a built in siren, but it's one of the quietest we tested. This system is compatible with more smart home devices than the others we tested. You can connect Z Wave, ZigBee, Alexa, Nest and Google Home and over 70 other devices.

You can set up different modes such as home, vacation and away and specify which devices are active in each mode. There's no monthly fee for self monitoring, but you pay extra if you want cellular backup and security camera backup $10 for your system. You can also get monthly professional home monitoring $30, which includes the backup features mentioned above. One of the best things about abode is you can buy the amount of professional monitoring you need on a monthly, weekly or even a three day basis. This is particularly convenient when you can't monitor the system on your own during vacations.
