I had never heard of Telesec before so was a bit wary but am extremely satisfied. I needed an alarm system installed with two separate zones to separate two units within my home and Waleed from Telesec provided very helpful advice on the various options. I got some price comparisons on installing a two-zone system and the price was comparable. The after installation service has been excellent. He answers all of my questions promptly and honestly. I'm very happy with this company and with Waleed specifically.
