"I would highly recommend the team from Access Denied Security. I recently had an entire CCTV home security and alarm system installed and the entire process from the initial quote to installation was hassle free and straight forward. "
Shawn Glick
"We have a computer and electronics repair business in a - lets be honest - somewhat rundown strip of shops in the outer west. After some neighbouring shops were vandalised we decided to beef up security, install conspicuous cameras and add access control to the adjoining units. Long story. The point is that the Access Denied Security guys were very helpful, informative, and provided good advice around a comprehensive security system. Highly recommended!"
