We just had JTL installed the security alarm in our office. Very nice people have done very nice work. Due to the nature of our business, we need one of the offices strictly secured, they provided perfect solution and added additional layer of security other than we requested, which would be a huge advantage for our regulatory site inspection. They did a fantastic work, and the wiring was very neat and organized, and they did spend time to make sure all wires went behind the drywall and are not visible. Both technicians are very knowledgeable, as well as the owner who I met before. After the installation, they spent time on showing me how to use the system and even how to download and configure the mobile app, very patiently and clearly. I would like to give extra 5 stars if that was possible. I highly recommend this security company!
