COUNTERMEASURES
HEADSCREW SECURITY MARKING PEN




When doing countermeasures sweeps, as soon as you check and clear an electrical outlet, phone jack or electrical light switch, you can mark the screw heads with an invisible UV pen. Once that is done, all one has to do is check the screw head with a UV light source to know in an instant if the outlet has been opened. Below are sample photos to better understand this technique.

 

 

The above photo of an electrical outlet shows a marked cover under normal conditions
and under the UV light. Note the location of the screw head. The UV mark shows that when the cover was cleared, the screw head had a vertical line. The screw head now has almost a horizontal line which means that the screw head has been turned. This is a strong indication that the cover has been opened. In such a case, the cover would need to be removed and checked again.

 

The above photo of an electrical outlet shows a marked cover under normal conditions
and under the UV light. Note the location of the screw head. The UV mark shows that when the cover was cleared, the screw head had a horizontal line. It's still the same so the screw heads on this cover have not been moved which means the cover has likely not been opened.

The Countermeasures security pen has a UV marker on one end and a UV light on the other end which works with small watch batteries. Easy and simple to use, the Countermeasures pen can be used to mark electrical outlets, the screw heads on phones, phone jacks, computers and anything else electrical including clocks. Once security marked, you know in an instant if the target item has been tampered with and opened by simply checking the location of the screw heads with the UV light source.

You can also use the Countermeasures Security Pen to mark money, place invisible serial numbers on products and invisibly mark anything. It will mark on about anything and is a great detection tool.
