Essential Info

Hidden Sensor - Invisible Assurance

Peace of mind - that's what Hidden Door Sensor brings to your home. With Hidden Door Sensor and an INSTEON Automation Controller, you will always know whether the front door has been opened or if you forgot to close the door to the garage. Hidden Door Sensor installs inside the door or door frame, reporting door activity wirelessly to your INSTEON home.

Now You See It, Now You Don't

Nothing makes your home smarter than adding sensors; but even our unobtrusive INSTEON Open/Close Sensor can be too large for certain décors and locations. That's why we've created the Hidden Door Sensor. Instead of mounting to the surface of your door, Hidden Door Sensor is installed inside the door frame or even the door itself. The result is a completely hidden sensor that stays out of the way, monitoring doors without the slightest visual impediment.

Installation - Power Tool Time

Using a 3/4" drill bit, simply drill a hole into your door frame along the hinge-side of your door. After cleaning out the hole of any wood shavings, simply slide Hidden Door Sensor in and secure it with the included screw. And in the event that there is a substantial gap between your door and the frame, we've included a spacer to ensure that your sensor will activate every time your door is opened or closed.

Got Metal? - Equal Opportunity Installation

Wood doors are easy; almost every home owner has the tools necessary to drill through a wooden door frame or door. But what if your door or door frame is made of metal? Hidden Door Sensor is just as easy to install in the door itself along the hinge-side of the door. If both your door and door frame are metal, we suggest using INSTEON Open/Close Sensor instead.

Windows? - Supports Some Window Styles

While Hidden Door Sensor works best with doors, it is possible to install with casement windows. Because the sash of most windows will be too narrow for Hidden Door Sensor, we suggest using the window frame exclusively. And if you have modern vinyl windows with sophisticated moisture barriers behind the frame, it's probably best to use INSTEON Open/Close Sensor instead. No one wants to trade a hidden sensor for a leaky window.

Required Accessories For the best INSTEON network performance, be sure you have properly installed at least two Access Points or other dual-band products.

Note: Open/Close Sensor does not transmit X10-compatible RF signals.
