Just had a Hi-Tech interactive alarm system installed and everything went great. The sales guy was not pushy. Had lots of knowledge and was thorough. When the installer arrived he was polite and experienced. The interactive alarm allows me to control my system through the web and even gives me automation options. Overall very pleased with the purchase. I even did a test after the tech left and got a quick response from the monitoring station and was able to view the history through my online login. I would recommend Hi-Tech if you are looking for an advanced alarm system.
