"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 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."

"We like their service. We haven't had any problems. They are very good. This was the first time we've had an alarm/security system in our home. The supplier is ADT. I like that I can set my alarm every night before I go to bed."

"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 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. 

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

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 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.

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.
