"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 recently had 1st Security install a system in my new house and so far have been very pleased with all aspects of the system, from the initial estimate to the installation to the functioning of the system itself. Jeremy did our initial estimate and provided us with a thorough explanation of the system. I already had done a significant amount of research comparing Alarm.com to ADT and some of the self-install options, but Jeremy was able to provide even more information and help me to understand better the pros and cons of each approach. Larry did our installation and also was very friendly and knowledgeable, explaining each step of the installation process and providing me with a tutorial at the end. My wife and I have had no issues with the system so far. It is very intuitive, and we have been able to customize it to fit our unique needs. I highly recommend considering 1st Security for anyone looking at installing, switching, or upgrading their security system."

"We have our second home in the mountain so they were able to send it and he was able to work with our installers and it worked out fine. So far we were are pleased with it. We were with another security system for 12 years and we changed because their selection of product was of a higher grade. They are excellent."

"We're very happy with the security system. They were very professional. They answered all my questions well. I think they did a good job installing the system and explaining how it works. They did not fall short at all, in fact the came out twice.  The first time, they're going to have it installed and when they explained how they were going to do it, my wife said I just don't know if we need this, lets not do this. I told them to hang on to what information we had given them. I called them back and they were very gracious about that."

"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."

"Don gave me a window of time for his arrival; between 2:00 pm - 3:00 pm and was at the front door just after 2:00 pm.  He went right to work on the aftermentioned electrical projects.  While he didn't have all the materials he needed to complete my work on his truck and had to make a run to the local hardware store, he didn't waste any time while working at the house.  One of the projects required a larger ladder than he had with him and he re-scheduled right then and there for the completion of that work.
I was extremely please with the work and ill definitely consider Master's Electrical Services for my next home improvement.

Security Doors FAQs, answered by experts

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.

When deciding whether a home automation system is right for you, consider the advantages and disadvantages first.

Pros

  • Home automation can help make your home more energy efficient, possibly lowering utility bills.

  • A wide range of automated solutions is available to meet your needs.

  • Centralized and remote control of different home automation systems.

Cons

  • Home automation can be costly.

  • Not all automated systems are compatible with each other.

  • Over-dependence on home automation can be problematic if systems cannot connect to the cloud.

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

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.

If you're wondering what you should do with your old security alarm system after installing a new one, one option is to properly dispose of it at an electronics collection facility. Otherwise, if your old system is still in good shape, you can also donate it for someone else to use in their home.
