"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."

"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."

"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

A potential weak link in any security system is poor connection strength or dropped signals, particularly in the case of a fully wireless system. You also want to ensure a reliable connection to get a hold of your service provider quickly. Also, you should exercise caution when handing out sign-in credentials to people outside the household.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

Not all security systems are equal, so familiarize yourself with the many features available and any associated costs. Decide on a wireless or wired system and look at monthly subscription fees to access the service. Finally, read plenty of reviews to check out the efficacy of your intended security system.

A home security system can be a worthwhile investment for several reasons. Financially, it may qualify you for a discount of up to 20% on your home insurance premiums, which can help offset the initial setup costs and any ongoing monitoring or subscription fees. For many, the primary benefit is the peace of mind that comes with enhanced security, especially for those living in areas with higher crime rates. Ultimately, whether a system is worth it depends on your personal preferences, the value of the assets you wish to protect, and your overall safety concerns.

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.
