Are Wireless Security Systems Secure?
The answer is YES and NO.
The reason for my answer and covering both sides of the spectrum is it really depends on the wireless security system in question. Also that raises more important questions such as, frequency, distance and encryption.
When i say frequency I am speaking of the radio frequency that the security system uses to communicate wireless as well as transmission signal.. Here is an example of some of the frequencies security manufacturers use: 900Mhz / 433Mhz / 345Mhz etc. So what does that mean ? Well, any device that receives a wireless signal from a specific frequency that never changes can be jammed or compromised. How this is done i would preferably not say as it is illegal and would not want to contribute to anyone’s attempts to do this.
Does That Mean All Wireless Security Systems Can be Compromised ?
Absolutely not, currently there are several high end security systems that have combat this problem and help reduce the threat. The IQ 2 from Qolsys is a great system and currently carry S-Line sensors that use a rolling code encryption. The purpose of this is to ensure that every sensor transmission signal is unique and unable to be repeated using a replay device. A unique key is shared from the device to the keypad once it is learned in so that it never sends the same code and only the keypad and device will know what the next transmission will be. This encryption is great and will deter and help eliminate burglars using a repeater to bypass the system.
Can Distance Be A Factor With Wireless Security ?
Distance is definitely a factor, the further the sensor away from the keypad the weaker the signal or communication will be. If the sensor is out of range (too far) then there will be a malfunction on the sensor on the next supervisory check, meaning the last transmission sent will be the last command taken until another is sent or received if at all. There is a solution at this time for long range sensors needed for big homes or businesses, it is called Power G. These sensors are the industry’s most robust sensor line that addresses common range and functionality demands. The average sensor should work up to 100 feet before giving problems, the operative word here is “should”. While Power G sensors have been tested to work up to 1000 feet of open air.
So if you are thinking of purchasing or having a wireless security system be sure to address the basic concerns listed above. The difference between buying online or off the shelf instead of choosing a professional security company could be the biggest mistake ever made. Remember in most cases you get exactly what you pay for and at times even less. 🙂
