"This was the third company we contacted after having no follow through with the first two. I explained to Ramiro of Northbay Technology what our problem was. He had a technician here in a few days, he fixed the problem as well as giving us useful feedback on our system. Our streaming and dvd system work after not having it for almost 3 months! Ramiro also called afterwards to make sure everything was still working. What a treat to find a quality company that does what they say they’ll do and also offer great customer service."

Home Security Systems questions, answered by experts

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.

False alarms happen, and they could be due to a problem you need to troubleshoot, like faulty wiring, a mistaken setting, or the system needing an update. Turn off your system by disconnecting its power supply (both the battery and transformer) and give the manufacturer a call to see what they advise.
