Commercial Security Systems

We custom-tailor every commercial security system we install to ensure it meets the unique needs of your business or organization.

In addition to offering 24/7 monitoring and intrusion detection, we can integrate fire detection, video surveillance, and access control into a custom-designed security package.



Access Control Systems

Determine who has access to your buildings, offices, or classrooms with a customized access control system.

We can also convert your facility to electronic door locks instead of using multiple sets of insecure keys.

You’ll have complete control over the entire system, including limiting access, buzzing in visitors, and monitoring door activity.

Video Surveillance and CCTV Systems

Today’s CCTV systems offer high-resolution video and artificial intelligence (AI) that will help keep your business or organization safe.

Modern video surveillance cameras now offer human and vehicle detection technology. The system helps reduce false alarms by intelligently determining whether a car or human-caused the movement.
