A contingency plan is critical to many facets of life, and your property’s security is no different. When searching for alarm systems, you need to ask yourself this question: Will you have a way to contact monitoring agents if your internet service or power is disrupted? Let’s quickly investigate how security systems communicate and why you ought to have cellular and battery backups.

How do alarm systems transmit information?

Historically, alarm systems transmitted notifications through the copper wiring of standard landline phones. During urgent events, the security system could take control of the line to warn monitoring agents right away. But as you’ve noticed, traditional phone lines are becoming obsolete due to the meteoric rise of wireless and cellular technology.

Modern systems use cellular connections and wireless protocols

You can still discover alarm systems that connect through standard phone lines. However, most current installations supplying features like home automation and remote access use wireless communication standards like Z-Wave and Wi-Fi, as well as cellular connections. Regardless of what your system counts on as its principal method of communication, you must have a backup. Redundant systems are essential to providing continuous connectivity. 

Home security battery backups are essential 

If your phone line is cut or your internet goes offline, you need a cellular fallback to reach your monitoring team. But what about electrical outages? If your property suddenly loses power as a result of extreme weather, you need backup power to stay online. The best alarm systems in San Antonio will provide dependable battery backups to power your system for several hours, an entire day, or longer. 

When purchasing an alarm system, be sure you know how it connects and if there is a cellular and power supply backup.
