Cellular Connection vs Landline Connections


There is no easy answer to whether or not you should use a cellular or landline connection for your home security system. If possible, we highly recommend using both for maximum home security and efficiency. Choosing the connection that’s right for you depends on your needs and situation. Below we’ve outlined some of the strengths and weaknesses for each connection. Read each section carefully to best understand which connection is best for you.


Landline connections for home security have been an industry standard for decades. The landline refers to your home security system connecting to a phone line which uses a solid medium telephone line such as a metal wire or fiber optic cable for transmission. One of the most recognized weaknesses of this system is the vulnerability of being cut thus deactivating any signals from the home security system itself. Up until recently one of the landline’s greatest strengths was it low-cost connection to home security systems. Most home security companies offer monitoring packages, connected to landlines, and lower prices compared to wireless cellular.

With increased use of cellular phones, fixed landlines have seen a dramatic decrease in subscriptions. In 2003, the CIA reported approximately 1.263 billion main telephone lines worldwide. In 2008, they had 1.27 billion fixed subscribers. Growth in landline subscriptions have slowed down considerably. More and more consumers are switching to cellular as their primary phone connections. Home security companies are having to adjust and adapt to this paradigm shift thus offering more cellular connection home security packages.

Wireless Cellular

It’s no secret that landline connections are susceptible to being cut by potential intruders, contrasted by wireless cellular connections that use radio waves for transmission. One of the greatest strengths of cellular connections is the increased range of signals allowing access to a wider geographic area. In addition, wireless cellular connections cannot be cut, thus increase the security and reliability of a security system. Some of the disadvantages of wireless cellular systems include:

  • Cost. The components of a wireless systems are often more expensive up front than wired systems. Monitoring packages for wireless cellular often run at higher monthly costs.
  • Interference. Bad weather can interfere with the signal of a wireless alarm system. In addition, appliances that use radio frequencies can also interfere with your home security signal (more common in cheap home security systems).
  • Battery dependence. Wireless systems require the use of batteries which means frequent battery checks and, for larger systems, battery replacement often.
