Fire Alarms

CO2 Sensors

1st Security is bar none the best value in the home security market!!

What I have for what I pay is unbelievable! I have every window and door sensored, motion detectors with cameras, video cameras that I can access via app and my Qolsys keypad is better than any other keypad I’ve used. The service and expertise with the staff is the best I’ve had, period. They bend over backwards for me when I contact them with simple questions about my system’s features! I would recommend 1st Security to my grandmother!! –Kelly Schauf

Smoke Detector

The IQ Smoke is connected to your IQ Panel and monitored 24-7, whether your system is armed or not. And because your system is always connected, you’ll be informed of the problems, wherever you are. The IQ Smoke detects the presence of smoke using photoelectric smoke-sensing technology and conforms to UL 217. Also functions as a heat detector.

Carbon Monoxide Detector

This monitored detector ensures your home stays safe from dangerous invisible Carbon Monoxide gas. Connecting directly to the IQ panel, this device is operating 24-7, whether your system is armed or not, and can inform you of any danger ensuring you’ll know exactly if and when danger is present in your home.

Checking up on your kids, pets, and assets while you’re away is now easier than ever!

With our indoor and outdoor security cameras, you can easily monitor your property in real time, get instant alerts with smart clip capture, and capture every moment with continuous recording. In the event of a triggered alarm, you get immediate, live footage of what is happening right on your property to give you peace of mind.
