State-of-the-Art Camera Technology

Human, vehicle and license plate recognition technologies add additional layers of state-of-the-art protection to your building. Check out the below videos to see how this unique technology works.

Human and Vehicle Detection

Human and vehicle detection technology drastically reduces false alarms from motion created by non-threatening objects.

This technology can determine if a human or vehicle is causing movement—or something else entirely.

The system will generate an alert if it detects a human or vehicle. Anything else that causes motion will not create an alarm.

The line-crossing feature sends an alert to property owners when a human or vehicle crosses into or exits an area.

These features drastically save time, money, and headaches for businesses and other commercial entities that require external surveillance.


Smart Search Technology

Older surveillance cameras made it a pain to search a week’s worth of footage to find one event.

Locating one event is now easier than ever, thanks to camera surveillance systems incorporating AI.

Smart search technology lets you quickly search large amounts of video footage based on certain criteria. For example, the system will instantly find all instances of a man in a green shirt.

You’ll now be able to find specific events in mere seconds instead of taking hours to comb through footage manually.

License Plate Recognition

License plate cameras allow property owners to capture pictures of any tags that enter the premises.

The system will send an alert if the camera detects a vehicle with a specific license plate number entering your premises.

The potential and opportunities for this technology to protect your business are endless.




“I called Security Alarm to check on cameras for outside since we had used them in our Ag business for years. The process to get lined up was simple and Larry was very thorough in explaining everything.

They were out in just a few days to install them. Both guys were very friendly and professional. It didn’t take long to install and I know they probably had wiring issues to deal with.

They did a great job and the cameras show exactly where I wanted them. I am very pleased with the service and products installed.
