1. A glass break detector, comprising:
- a wall mounted housing;
a terminal block carried by the housing;
a first output of the terminal block for a glass break detecting means that detects glass breaking only for noise above a glass breakage threshold; and
a second output of the terminal block for a noise detecting means that detects noise at least in an audible frequency range and generates an audible noise output once a noise is detected in the audible range without breaking glass;
said glass break detector having a plurality of modes settable by a user from within the housing including a first mode wherein only the second output triggers a video camera to record in the area of the glass break detector and a second mode wherein only the first output triggers the video camera to record in the area of the glass break detector.

Abstract
A glass break detector is provided with microphones for detecting glass breaking, and microphones for detecting noise, and generating a noise output once a noise is detected. The noise output triggers a video camera to record in the area of the glass break detector. Also, a security apparatus is provided, having a video dome, a video camera provided in the video dome, and one or more microphones provided on an outside surface of the video dome. If a noise is detected by the one or more microphones, the video camera points to a direction of the noise by determining the time of arrival of the noise, and the camera begins to record.

14. A security apparatus comprising:
- a wall mounted housing;
a video dome;
a video camera provided in the video dome;
a glass breakage detector within the wall mounted housing;
a switch in the glass breakage detector having a plurality of switch positions settable by a user from within the housing and one or more microphones provided on an outside surface of the video dome;
wherein the switch has a first position of the plurality of positions that causes the video camera to point in the direction of a noise only upon detection of an audible noise without breaking glass at least in an audible frequency range by the one or more microphones and a second position of the plurality of positions that causes the video camera to point in the direction of the noise upon detection of an audible noise with breaking glass. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A method of tracking a noise source, comprising:
- providing a glass breakage detector within a wall mounted housing;
providing a video recording mode switch in the glass breakage detector having a plurality of video recording modes of settable by a user from within the housing, the plurality of video recording modes including a first mode in which records video only upon detecting an audible noise without glass breakage exceeding a first threshold value; and
a second mode which records video only upon detecting an audible noise exceeding a second threshold associated with glass breakage;
in the first mode detecting an audible noise exceeding the first threshold without breaking glass at least in an audible frequency range by providing one or more microphones on an outside surface of a video dome and in the second mode detecting an audible noise exceeding the second threshold with breaking glass;
providing a video camera inside the video dome;
determining a direction that the audible noise is coming from based upon the selected mode; and
directing the camera to a direction of the audible noise. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
