Is Your Wireless Security System Safe?

54163030 - information security online privacy protection conceptWireless has made life easier in many ways. You can print something from your living room using your wireless printer. Your wireless phone means you don’t have to buy a 30-foot curly cord and drag it around the house. (Remember that?)

Security systems are wireless, too. While wireless has made life easier, it also makes our homes and devices more vulnerable and not all security systems are created equal. Here is what you need to know to keep your family and valuables safe.

How Wireless Works

Wireless security systems use radio frequency signals sent from your door or window sensors. Those sensors trigger an alarm if breached. According to a study done by two researchers, most systems do not encrypt or authenticate the signals sent from those sensors. That means a hacker could trigger false alarms or even block the signal, preventing the alarm from sounding and preventing the system from alerting fire or police officials. Some alarms come with anti-jamming measures, but hackers have found ways around those, too.

How to Protect Your Home

You really do get what you pay for in security. Inexpensive, DIY systems are vulnerable to hacking. Lyric Systems by Honeywell offers 128-bit encryption. It’s more expensive, but more secure. Any system you choose needs to have encrypted signals. Some alarm systems broadcast on multiple channels, making them tougher to jam. Ask your security team about these options. 

Another option is to install a wired system. Some security experts point out that thieves can cut the wires, but in some residences, the wires are difficult to access, making this a more useful approach.

Don’t buy a used system or used cameras. The previous owners may be thieves who retain access to those devices.

Change usernames and passwords. Anytime you buy an out-of-the box system, a new wireless router, or anything, you MUST change the username and password from the default. While this won’t necessarily prevent all hackers, you might as well make it a little tougher for them. As Forbes found, one security company mailed systems to people with the default login of username “admin” and password “admin.” Because those businesses never changed their login information, it was easy to guess and access their system.

If you have something to protect, such as valuable jewelry, electronics, or art, invest in a good security system installed by Secur-Tek. Our team can recommend a system that fits your security needs.
