Do not get Vivant. They installed my system and it never worked properly. They activated the system without telling me I needed a permit, as well. After a false alarm with no alarm permit with the worthless HPD, I am out$100. I made an appointment for the installer to return and fix the system and he never showed, never called. The problems with it? They installed a doorbell camera and the doorbell ceased to function, I got never ending (sometimes alerts to my phone 4 times an hour) that the battery is low in the downstairs motion sensor. The fire alarm sensor place next to my smoke detector fell off the ceiling after a week. The front door could not be closed all the way or the new automatic door lock/security lock on the front door would not close; I had to 'almost' close the door to lock it. Had the system a month and no one came to fix any of those. I called and canceled. They will not reimburse me for the false alarm. So aside from the headaches of trying to find batteries (wasted gas and hours going to store after store) for the motion sensor, the 3 hours I gave them to install the system, the $15 I paid to register my system with HPD, I am still liable for the $100 fine and $15 surcharge. If it sounds too good to be true, it sure is. Do not recommend them ever.
