"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!"

"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."

"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."

""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.""

"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."

"It was easy. No one came to my house. I answered their questions. Those answers provided them with what they needed to send me a DIY system to arm my home. Everything was explained and all seemed simple until I got the kit. Nothing was wrong with the kit, however, I was nervous that I would not line up door and window sensors correctly. Afterwards, I could not figure out why I was so hesitant and nervous. I have tripped the alarmed, was quickly contacted and false alarm cancelled."

"Job went well. Joe re-arranged his schedule to squeeze me in. I bought a deal and he applied some of this towards materials so was very fair.- work seems fine. I only gave him a b in quality because I think he could have better secured the new outlet (I would have given him an a- if this was available!). That being said, all is working fine and I would hire him again. I think he's honest and fair.

Security Doors FAQs, answered by experts

Some but not all security cameras have monthly fees, depending on the specific camera system and the services offered with it, especially monitored vs. unmonitored security systems. Home security companies that offer monitoring services along with cameras will charge a monthly fee for monitoring and possibly for using the security cameras. Cameras that you monitor yourself as part of your own security system will not have monthly fees charged.

A steel door that's been toughened up with extra materials creates the perfect barrier. These bad boys are way stronger than your typical wooden or fiberglass doors, making them a fantastic choice for folks who want that extra layer of security for their homes. So, if you're all about keeping things super secure, a reinforced steel door will cost you more, but it is your best bet.

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. 

The main difference between different security sensor options is the type of motion each detects. A motion detector monitors obvious movements in hallways, entrances, and exits. On the other hand, a presence detector is more sensitive and captures smaller moves. A window sensor typically focuses on the opening and closing of the window, whereas a glass break sensor alarms you when a glass is broken.

Professional home automation services can include automation for nearly anything in your home, so the possibilities are endless. Some of the more common things homeowners use automation for include the following:

  • Heating and cooling for automatic comfort

  • Security cameras and emergency call systems

  • Door and window sensors to detect opening, closing, and break-ins

  • Solar system automation to maximize energy savings

  • Automatic door locks

  • Garage door openers

  • Speaker systems

  • Lighting

  • Appliances

  • Smoke and CO detectors

  • Blinds and other window coverings

  • Lawn irrigation systems

  • Water monitoring
