Home Security Systems questions, answered by experts

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

While security hubs can streamline the management of security cameras, the placement of cameras itself is often determined by factors like your property layout, security objectives, and areas of concern.

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

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. 

The biggest downside to a wireless security camera is that it's 100% reliant on Wi-Fi to capture footage at your home. Even when Wi-Fi is reliable, the range for wireless cameras may only be 200 feet or less. Drywall, brick, and other materials in your home can be enough to make your signal lag.
