Ion Security Products is known for its ability to design and manufacture innovative concealed wireless security transmitters for the residential and commercial markets. Our goal is to provide the highest quality products that work with leading alarm manufacturers, at an affordable cost. We bring new technology and form factors to the security industry by thinking outside the box.With wireless security one of the fastest growing parts of the security industry, the most objectionable to the homeowner is that most installations are done with surface mounted sensors that are obtrusive to look at and design around. Ion has designed solutions to combat this with our line of concealed wireless sensors. Ion first developed the Micra as a solution for builders who wanted to not only have wireless security sensors hidden from view but also to avoid the high cost of pre-wiring every window and door. At the first showing the product at ISC West in Las Vegas, Ion won the "Judges Choice Award" for best new product in the Residential new products showcase.The Plunger has now been developed using the same patented technology as the Micra but adapted for use with a door. It's unique patented Plunger style is designed to be installed on the hinge side of a door keeping it completely out of site and also not requiring any drilling or setting of a magnet in or on the door. The Plunger remains completely hidden from view and unable to be tampered with.
