Abstract: A sensor-camera ganged intrusion detecting apparatus according to the present invention includes a sensor unit 1 for detecting an object Q in terms of a change in amount of reception of detection rays from a detection area A0 to An, an image processing unit 4 for detecting the object Q in terms of a change of a video signal MS from a specific area AC1 in an area shot by a camera 2, which specific area AC1 has a portion overlapped with the detection area A0 to An, an area setting unit 3 for setting the specific area AC1 on a monitor screen 6 coupled with the camera 2, and a detection signal generating unit 5 for generating an object detection signal DE1 based on a detection signal PD from the sensor unit 1 and a detection signal MD1 from the image processing unit 4.

Abstract: A stereoscopic antenna includes a planar electroconductive pattern 2 adapted to be grounded, a loop-shaped antenna body 3 having an axis C0 lying perpendicular to the planar electroconductive pattern 2, and an antenna connection 4 for connecting the antenna body 3 to the planar electroconductive pattern 2. In this stereoscopic antenna, the ratio H/D of the longer diameter D of the antenna body 3 relative to the height H of the antenna body 3 as measured from the planar electroconductive pattern 2 is chosen to be within the range of 0.1 to 1. By making the antenna to have a three-dimensional structure different from any of the loop antenna and the rod antenna, the stereoscopic antenna compact in size can be obtained having a uniform field radiation pattern and giving rise to an increased gain.
