"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."

"Bob did an excellent job on each part of my house that he fixed. I couldn't figure out the reason a window fell down and he made a small adjustment and it worked! Gutters and downspouts are secure now. He also adjusted the windows for air conditioners to fit and drain properly. He could fix anything that I needed to be fixed."

"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."

"I switched from another company to Security One, they use the same equipment. They had to come out and recode everything. I simply switched because of the financial benefit. I have only had them for a few months, and I haven't had any problems with them. They save me some money every month.  When my alarm went off, they did call me."

""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.""

"I own a small business and someone tried to break in, so I needed the locks changed on the main door. Nick said that would be no problem, he would come as soon as he finished the current job he was at. He showed up in a timely manner, was nice and professional and did a great job. He even offered to change the locks on all my other doors as well, and didn't overcharge me. I would definitely call him again."

"That's the name I am vaguely familiar with; it's a home security company that is license to ADT franchise or dealer if I am correct.  They were very good.  They were prompt; they were quality.  The individuals move their business.  They were very timely and it was a good experience."

"First the good:
The up front cost cant be beat since all of the sensors and control panel were no cost to cover 20 doors and windows.  Installation was pretty straight forward and the phone reps were fairly knowledgeable and professional.  I added a couple features like an extra key pad, siren and glass break sensors that cost aprox $350.  The extras were a little pricey but compared to the $2000 another provided quoted, it was still a deal.
The control panel is cellular based so cutting your phone lines will not effect the alarm.
Now the not so good:
The quality of the sensors has not been very good.  I have had 2 DOA when the packages arrived new and 2 failed within several days.  When I contacted Protect America they were very nice about sending me new ones, but it took weeks and a couple calls before I saw the first replacements.  The second set of replacements that arrived for the failed units ended up being the wrong sensors.  Their shipping department does not seem to have good quality control.  The next very annoying element is the wait time on the phone when you are trying to get anything set up.  I spent a couple hours on hold working through the set up the first time and at least an hour the second time when I installed the replacement sensors.
Some cautions; make sure you hide the main control panel because if an intruder disables it before the alarm has sounded for 60 seconds, the police may not be notified.  Also they only call to check if everything is ok if the alarm is not canceled for 60 seconds.  So you can not be sure if the signal is getting through.
Monthly monitoring fee is high, but since the system was intially free, even after 3 years it is still the cheaper route.
Now that I have the equipment, once our contract is expired I will find a different alarm provider that responds to every alarm.

Security Doors FAQs, answered by experts

Home security cameras typically do not record continuously 24/7. Most options use motion detection technology to trigger recording when they sense movement or a significant change in their field of view. This approach conserves storage space and reduces the need for constant monitoring. When motion is detected, the camera starts recording and may send alerts to the homeowner. However some cameras offer the option for continuous recording, but this requires substantial storage capacity and may overwrite older footage when space runs out.

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home. Some wiring may need to be added, but most home security systems do not require a lot of additional wiring. Wireless security systems can easily be installed with minimal additional wiring, if any at all. Most wireless security systems can be monitored and controlled from your smartphone, and the cameras and sensors operate on batteries.
