"SafeStreets’ alarm system is fantastic. The motion sensors, door/window contacts, and cameras work flawlessly. The home automation features are a huge plus—I can control everything from my phone. Highly recommend SafeStreets to anyone looking for reliable security."

"Last weekend had someone pry our side door open to our exterior garage and the ADT door sensor picked it up immediately. The alarm siren was loud and scared the person off. Someone from the response center called within 30 seconds. We’re fortunate that the security system did what it is supposed to. Feels like we made the right call going with an ADT security system."

"I have had Cransten Smart Security for about a year now and I just want to say how much I love the Camera quality. All of my neighbors with their DIY systems can't make out anything. Ours can make great detail at night time. Plus there is no service contract!"

"Install was easy. Up front cost was pretty low with Angie's List coupon. Monthly price is a little high compared to competing companies. Response time with alarms is excellent. I was advised to use glass break alarms within 10 ft of my first floor windows, which we installed correctly. I asked prior to installation if having one in the kitchen would cause false alarms due to dishes clanging, etc. I was told the glass break alarms are configured to a precise frequency that alarms with breaking glass. So, not a "no", but not really an answer. Well, every time we cook dinner, wash dishes or empty the dish washer, the kitchen glass break alarm gives a warning which would sound the alarm if it was set. This has caused us a number of false alarms while we've been away due to shifting bowls or plates in our drying rack. For the first several we've had to pay our police department $120 to check the house, and I was only notified after the first alarm that there was a cheaper option for a security company to drive by to check for a break in."

"We just replaced our outdated and expensive security system with Smith Thompson Security. Our contacts with sales and support were friendly and helpful. The installation technician said our old system was usable and up-gradable to the new technology. We added cameras as well. The tech was knowledgeable, friendly and full of tips on using the system. Total monthly cost for this new improved security was about half of what we were paying out to the old national company. So far, we are very, very pleased with our choice."

Security Doors FAQs, answered by experts

It depends on the type of sensor your home security system uses. If it’s a motion detector, any moving thing could set it off, from a roaming pet to a wind-blown curtain. Contact sensors would be triggered by the window being opened or moved. Also, be aware that any sensors placed too close to your vents could trigger false alarms whenever your heat or air conditioning is running.

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

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

Installing a gate on your property is often a worthwhile investment, despite the initial expense. Gates enhance your home's curb appeal and can increase its property value, making them more attractive to potential homebuyers. They provide significant security benefits by keeping out unwanted guests and increasing privacy for your household. Additionally, a gate can help keep children and pets safely contained in your yard.

For driveway gates, automatic versions are particularly convenient and tend to add more value than manual ones. The choice of gate material also plays a role in both aesthetic appeal and security. Beyond driveways, side gates can improve accessibility to your rear yard, making the outdoor space more usable. Overall, whether for security, safety, or aesthetics, installing a gate is a valuable addition to a property.

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.
