"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

Technically, there isn't a difference between safe rooms and storm shelters. Both are designed to protect you from storms and extreme weather events. People often use “safe room” when discussing a shelter inside a building and storm shelter when talking about a detached unit. 

Additionally, a safe room is understood to have more functions than a storm shelter. You may seek shelter in a safe room when you believe an intruder is in the home or when under another type of threat. 

With the popularity of DIY security cameras and video surveillance systems, it’s important to understand the benefits and potential drawbacks to decide if it’s the right choice for you. Advantages and disadvantages include:

Pros

  • Video footage readily available

  • Reduced home insurance

  • Save on labor costs by installing security cameras yourself

  • Wireless systems are easy to move and set up

  • Monitor from your smartphone

  • Avoid false alarms

Cons

  • Features may be vulnerable to hackers

  • No direct link to authorities

  • Risk of installing the system improperly, reducing its effectiveness

You should be able to use your smart doorbell and access your video feed without a subscription. Subscriptions give you special features, such as night vision, downloading, and automatically saving footage for a set amount of days. It’s a good idea to compare plans among different providers before you commit. 

False alarms happen, and they could be due to a problem you need to troubleshoot, like faulty wiring, a mistaken setting, or the system needing an update. Turn off your system by disconnecting its power supply (both the battery and transformer) and give the manufacturer a call to see what they advise. 

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.
