We had service scheduled to update our system and add doorbell and security cameras. The crew arrived at the scheduled time, installation was performed in a professional manner, with all work areas being cleaned up upon completion of installation. The lead technician assisted in installing and setting up the apps on our phones and walked through their use and the use of the new key pads installed. I would recommend Custom Security to anyone needing a security system.
