"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"I regret ever choosing SafeStreets. The whole process was frustrating from the start.

"The install of the burglary system went fine. The complaint is the facilitator (Eric Schoonover of Secure24 Alarms) promised to include smoke/fire monitoring but did not. He has been unresponsive about how to resolve this problem. His attitude seems to be "So what? There's nothing you can do about it now."."

Home Security Systems questions, answered by experts

The most secure lock for a front door is typically a deadbolt. There are many types of deadbolts to choose from, the most basic of which is the standard single-cylinder deadbolt. This is the lock you find installed on most front doors. For added security, you could go with a double-cylinder deadbolt, which requires a key to operate the lock from both the outside and the inside. 

Leaving a light on at night probably does not deter burglars as much as we would like. While there isn’t much evidence supporting the theory that lights deter burglars, there’s not anything disproving it either. If you feel like it offers added security because a burglar thinks you’re at home, then you can set your lights to a timer so they go off and on at intervals, mimicking someone moving around inside the house at night. A better idea is to install motion sensor lights in your yard.

Faulty sensors, weak signals, false alarms, and control panel malfunctions are common problems requiring repair.

You don’t need to completely revamp your security system constantly, but it’s a great idea to give it a once-over every year. Look for potential upgrades or new features—like smart home tech or replacing outdated equipment—that could boost your safety. If you make any significant changes, let your insurer know as they may adjust your discounts to reflect your improved security. Staying on top of your security not only keeps your home safe but ensures you’re getting the best possible rate on your insurance.

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.
