"It went great!  From Travis the sales person to Noah the installer I couldn't have asked for a more professional and through team to deliver my home security needs.  We just bought a new house in a neighborhood that's up and coming but there's still an element that we want to protect our home and valuable from.  Security One helped us find a system that we could monitor while we're away and that would make my girlfriend feel safe when I'm not a home.  We highly recommend them especially Travis and Noah.  Ask for them by name!

"They system was installed for the basic, but anything that you wanted needed to be higher upgraded require alot of extra money for every upgrade.
 The 36.99 monthly fee was for only if your system is connected to a landline. I didnnt notice that they charge me $44.99 until my 1st month fee. Thats when I was told that they charge $44.99 because the alram was connected to my cable line instead. I was unaware of the different charges. When tec came out he didnt show up to fix the corrected. Had to call the main company for the no show. So they schedule another appointment and offered 2 window alarms to fix the correction but my bill still is $44.99. Default is that since I didnt have extra money to upgrade to the Pulse, you dont know if you turn the alarm to your house properly. I called the 800 number and they cant tell either!

Home Security Systems FAQs, answered by experts

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

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.

Thieves can open almost anything with enough time and the right tools, but they also prefer easy targets that are unlikely to get them caught. Forcing open gates is loud and difficult, and to be able to open one electronically requires extensive knowledge of the system, which most thieves don't have. Electric and other security gates are great deterrents because the thief will move to an easier target. If the thief is determined to enter your property, they will most likely find a different entrance point.

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.
