The house my parents bought came with a Vivint alarm system already installed so my parents activated it, but for some reason, the hardwired sensors show low battery, also, cameras don't work. Last time I checked, hardwired sensors DO NOT HAVE A BATTERY So my parents called Vivint, and the customer service... is ass, these people DO NOT know what they are doing 😭🙏 Took us 1 hour to get a technician to come out... 1 HOUR FOR THE DAMN VIVINT CUSTOMER SERVICE REPRESENTATIVE TO SCHEDULE A TECHNICIAN?!?!?!? Then we called to reschedule... and then it took 3 minutes to reschedule? The first rpresentative that scheduled the technician did NOT know what they were doing 😭🙏 They came 2 hours early, cause they got done 2 hours early, and the technicians were cool asf, they let me plug in some shit and yeah They replaced the battery that powers the hardwired sensor communicator and added the POE module to the cameras and connected it to the Smart Hub Three days later...the battery died
