"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!"

"I was very impressed with the staff, including Tory who stopped by and set up the initial appointment and Del who discussed options that matched our home style, developed the estimate, and explained how the company operates. The door was ready for installation much sooner than expected. The installers were very professional and efficient, and the quality assurance manager was very helpful to ensure everything was completed and that we understood how to operate the new motor, camera, and remote access. We are incredibly happy with the new door and the trim surrounding the door."

"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."

"My garage door would not properly open and close, so I checked the list for a reliable service company with a tune up deal.  Chris came out Thursday and checked the door, identifying that it was cracked, causing it to sag in the middle, and the track was warped.  Unfortunately, the bottom two panels were cracked, so a tune up or repair were not possible.  Chris called Andrew who was able to get me a quote on the spot for next day installation.  Tony and Henry came out Friday afternoon and completed the install, ensuring the everything worked properly. They worked quickly and efficiently and let the work site clean of debris and hauled away the old parts.  The price on the door and install was somewhat higher than others I found on-line but the quick turn-around and friendly service even that out.

"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."

Security Doors FAQs, answered by experts

It depends on the type of sensor your home security system uses. If it’s a motion detector, any moving thing could set it off, from a roaming pet to a wind-blown curtain. Contact sensors would be triggered by the window being opened or moved. Also, be aware that any sensors placed too close to your vents could trigger false alarms whenever your heat or air conditioning is running.

A study from the University of North Carolina found that security system signs were one of the top ten deterrents for burglars when choosing a target, so they do have some effect. However, you can get into legal trouble for putting up fake signage, so it’s best only to put up signs when you have the alarms to back them up.

Yes, many providers offer remote troubleshooting and monitoring for business networks.

Although some pet doors allow easier access for burglars or stray animals, there are ways to make pet doors more secure. To increase your home’s security, choose locking or electronically activated doors, use additional motion sensor security cameras, and install pet doors on a wall where door locking mechanisms are difficult to access.

Understanding the pros and cons of installing a home security system is the first step to deciding which one is right for you. A few of the advantages and disadvantages include:

Pros

  • Added security for your household

  • Reduced home insurance premiums

  • Many smart home integrations available

  • Security companies can monitor your home 

Cons

  • Expensive setup costs 

  • Subscription costs can add up quickly

  • Features may be vulnerable to hackers

  • Weak signal reduces the security of a wireless system
