CO Monitoring

Carbon monoxide and other poisonous gases can be instantly detected, sound an alarm and simultaneously notify our central monitoring station to dispatch help to your home.


Smoke Detection

Smoke alarms installed by Knight Security detect flaming fires as well as smoldering fires, instantly sounding the alarm and notifying the fire department.


Insurance Benefits

Many insurance companies offer discounts up to 20% for protecting your home with a monitored fire alarm system - saving you hundreds per year. 

Detecting Fire Danger 24/7

Installing a smoke detector in your home is a great first step and certainly better than nothing. But what if no one is home when the fire starts? What if your home is in a remote location and you're not there?

Home fire alarm systems from Knight Security not only detect the presence of smoke, CO, and fire but also instantly send a signal to our highly trained staff at the central monitoring station, who can dispatch help to your home 24/7.

Why Most DIY Smoke Detectors Are Inadequate

This NBC news segment explains why most store bought, self installed smoke detectors are not enough to save lives. Knight Security, by contrast, installs monitored photoelectric smoke detectors that sound the alarm at the first hint of smoke in the home.

Prevent Disaster Before It Starts

 Ideal for kitchens and bathrooms, laundry rooms and basements, environmental detectors can notify you when detecting floods, leaks and extreme temperatures—helping to minimize the risk of dangerous conditions and damages to your home and valuables.

Installed temperature sensors alert our central station and notify you by text when the temperature in the home rises or falls below safe thresholds.
