Tips for securing wireless video
Wireless technology may be one of the greatest innovations for security cameras. IP cameras with wireless capabilities are much more flexible than their wired counterparts, having the ability to shift to changing security needs or building layout. New developments in wireless standards, such as MIMO (multiple input, multiple output) allow wireless cameras to transmit at further ranges than before.
For all its benefits though, wireless IP cameras do come with a couple pitfalls. Wireless computer networks, especially home networks, are subject to a type of hacking called "wardriving," where hackers drive through neighborhoods with laptops and wireless cards, looking for unsecured networks to use. Sometimes, they just want the free bandwidth. However, there are some war-drivers who use data from unsecured wireless networks for identity theft, or as a disguise for black hat hacking like unauthorized entry into corporate or government networks.
The same principle applies to wireless IP video networks - war drivers equipped with a DVR or other such digital recording equipment could intercept wireless video feeds and monitor or record them. This could be a major security issue for the company or organization who uses the surveillance system, especially if the cameras record especially sensitive or confidential information.
Officials in Canada have quickly recognized this, after wireless surveillance footage from a methadone clinic was unintentionally intercepted by a car's backup camera in a parking lot. This type of accidental wardriving was successfully recreated by CBC investigators who received similar footage from a backup camera in a different car.
In an attempt to ameliorate this possibly devastating problem, experts have developed guidelines for securing and encrypting wireless security systems across Canada, and in general. Read more about the clinic case and get the full guidelines here
