Alarm Sensors
Alarm sensors are the basis of every security system. They notify you when doors are opened, glass is broken, and when motion, smoke or carbon monoxide is detected in your home. With sensor activity monitoring, you are able to receive notifications when doors are opened or when there is activity without the system being armed.

Door & Window Sensors
Door and window sensors monitor when doors or windows are opened. When a sensor is opened while your system is armed, it will go into alarm and notify yourself and dispatch the police.

Smoke Detector
Monitored smoke detectors alert both you and the fire department when smoke, fire, or heat is detected. Unlike traditional alarms, they connect to a monitoring center for fast emergency response.They’re especially valuable for pet owners.

Glass Break Sensor
A glass break sensor is installed with 25 feet of windows and are triggered when the frequency of glass breaking is detected. The sensor sends a signal to the control panel and will set the system into alarm mode. These sensors add another layer of security when paired with window sensors.

Carbon Monoxide Detector
Monitored carbon monoxide detectors track CO levels and automatically alert the fire department if danger is detected. They add an extra layer of safety and may qualify you for a homeowners insurance discount.

Motion Sensor
Motion detectors are installed to monitor movement within your home or business. Designed with a 35-pound weight threshold, they can detect human activity while ignoring most pets, helping reduce false alarms. These sensors add an extra layer of protection to your system.

Flood Detector
Flood detectors are installed by drains and basements to notify you of water leaks in your home or business. They will send you a notification as well as alerting the monitoring station to call you so you are able to prevent extensive damage to your property.
