There is no real reason for blocking a cell phone signal in your home or room, but if you do need one device that could jammed the frequency in your area, this fake painting might be something you’ll interested in.
Disguised as a nice looking painting, this device can make sure no accessible cell phone signals around its coverage. The coverage is around 80 meter radius, which is more than enough to set your home into an “Out of reach” area. Very suitable for Library, podium, stage or class rooms.
Powerful and effective, this cell phone jammer effectively disables any cell phone and will stop all signals on the GSM, CDMA, DCS, PHS, and 3G bands without interrupting any other electronic device. With the included remote control, users can turn the device on and off for instant jamming and unjamming. Also included is sensitivity control for partial and selective blocking of any mobile phone signal.
With a working radius of up to 80 meters, this device can be used in any location, but is found primarily in places where a phone call would be particularly disruptive because silence is expected or needed. The inconspicuous painting design effortlessly blends in with (and easily mounts on) the wall and is ideal for churches, hospitals, libraries, museums, movie theaters, class rooms, and for business meetings and legal proceedings.
This cell phone signal jammer is only $150 and you can find the details at Chinavasion. You will also get one extra 3D picture in case you dislike the default drawing.
