"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

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.

A deadbolt differs from a regular lock in its design, construction, and security level. Regular locks are typically used for interior doors, such as for bedrooms and bathrooms, and provide minimal security. They are easy to install and use, often featuring a simple locking mechanism on the inside. In contrast, a deadbolt is one of the most secure locks you can install on an exterior door. Its internal construction is designed to withstand significant force, adding a crucial layer of security that can deter intruders. While deadbolts may be more expensive and complicated to install, they are cost-effective for the security they provide and are built to hold up to wear and tear.

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. 

A potential weak link in any security system is poor connection strength or dropped signals, particularly in the case of a fully wireless system. You also want to ensure a reliable connection to get a hold of your service provider quickly. Also, you should exercise caution when handing out sign-in credentials to people outside the household.
