Evading Motion Sensors
This article is a follow up on a previous writing called 'Not Quite Security.' Mostly by accident I found that I could evade these simple motion detectors quite easily with a cell phone.
The facts are as follows;
Fist off we can appear totally invisible or undetected to these devices. I found that if I have the web browser open on my Nextel phone, I and anyone else can walk through these device undetected. This seems to work as long as I'm within 30' or so of the device.
Secondly it is know that every time my phone transmit data by following a link in the browser the motion detector will be set off or ding. so this gives me the ability to activate the detector any time I want to and appear invisible anytime I want to.
I wrote to the corporate headquarter to both alert them of the issue and to gather information on the make an model of the devices in use. After receiving no reply I called the security office. They immediately acknowledged knowing who I was and then refused to provide any information.
So what is one to do but to gather the information themselves. I visited the store and removed the motion sensor from the wall as to get a good view of it. It seems that they have removed any indication of the manufacturer from the device, so it is still unknown as to what type of motion detector we're talking about or who makes it.
More to come on the specifics I hope.
