"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."

"My next door neighbor's house was robbed last week, and I realized that I needed to do something to give me further peace of mind. Purchased new home security with ADT and opted to get the premium options with flood detection and carbon dioxide monitoring. Keep up the nice job ADT!"

"Delivery was delayed due to credit inquiry. After the concern was raised, shipment was rushed to us. Self installation didn't go as easy. Issue was resolved over the phone. The glass break sensor was a bit sensitive to loud noise such as cabinet door closing and door sensor repeatedly falls off and had to be reattached. Notification of alarm activation was fast and made to the right contact numbers. This prevented false alarm calls to the police."

"I recently had 1st Security install a system in my new house and so far have been very pleased with all aspects of the system, from the initial estimate to the installation to the functioning of the system itself. Jeremy did our initial estimate and provided us with a thorough explanation of the system. I already had done a significant amount of research comparing Alarm.com to ADT and some of the self-install options, but Jeremy was able to provide even more information and help me to understand better the pros and cons of each approach. Larry did our installation and also was very friendly and knowledgeable, explaining each step of the installation process and providing me with a tutorial at the end. My wife and I have had no issues with the system so far. It is very intuitive, and we have been able to customize it to fit our unique needs. I highly recommend considering 1st Security for anyone looking at installing, switching, or upgrading their security system."

"We have our second home in the mountain so they were able to send it and he was able to work with our installers and it worked out fine. So far we were are pleased with it. We were with another security system for 12 years and we changed because their selection of product was of a higher grade. They are excellent."

""What struck me most about Chris was his patience along with his professionalism. I had never used a private detective before and was a little nervous, but he took the time to answer all my questions and explain the process. He was extremely accessible and kept me updated on my case. If you want someone who is professional, courteous, thorough, and who gets the job done right, I highly recommend Chris and CSI Secure Solutions.""

Security Doors FAQs, answered by experts

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

Although some pet doors allow easier access for burglars or stray animals, there are ways to make pet doors more secure. To increase your home’s security, choose locking or electronically activated doors, use additional motion sensor security cameras, and install pet doors on a wall where door locking mechanisms are difficult to access.

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.

Options include wired or wireless systems with night vision and motion detection.

Strike plates and security plates are the same thing, but there are strike plates that offer more security than others. For the highest security, look for plates made of heavy-duty steel, reinforced strike plates thicker than regular ones, and extended strike plates. It’s much harder to break into a door with these strike plates because they hold up better to force from attempted entry.
