What isn't clear from the article is if the wireless channels were encrypted or not. Right now they're just using brute force to flood the channel which is going to cut off the panel from the sensor(s) regardless.

I cannot see an easy way to mitigate this. Even if it has anti-jam it is going to just shift the frequencies which you could also likely jam. I guess the panel could increase its output power to try and compensate, but all that does is increase the equipment cost of an attacker, not really stop it completely.

So I guess the main take-away from this is to go wired, not wireless for security system installs. However it is unclear if security systems really do much of anything anyway (as police often ignore home alarm calls as they're more often than not false alarms).

You're better off just spending the money on higher fencing with trellis skirting, motion flood lighting, and fake signs that say "protected by FakeCo Security." It won't cost you $30/month for the rest of your natural life and offers the same deterrent.

Most smash & grabs are 10 minute affairs. Some robbers will happily continue to rob with an alarm going off, since they know the response time won't be close to 10 minutes.
