Abstract
Abstract An intrusion detection apparatus for detecting the presence of an intruder in a forbidden space comprises a sensor, an illumination system, a sound system and a still camera. When the sensor detects the presence of an intruder, it switches on the illumination system and the sound system (e.g. a buzzer or an alarm), and activates the still camera to take a picture of the illuminated intruder. The sound system masks the operation of the camera so that the intruder is unaware that a picture has been taken.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
84 words
Intrusion detection apparatus adapted to detect the movement of a body in a space, comprising: a sensor adapted to sense a body in the space; light means adapted to illuminate the body in response to the sensing thereof by the sensor; a photographic still camera adapted to be triggered to photograph the body during its illumination by the light means; and a sound generator adapted to be actuated by the sensor to emit sound which disguises or overrides the sound of the camera operation.
Claim 2
Dependent Claim
84 words
Intrusion detection apparatus adapted to detect the movement of a body in a space, comprising: a sensor adapted to sense a body in the space; light means adapted to illuminate the body in response to the sensing thereof by the sensor; a photographic still camera adapted to be triggered to photograph the body during its illumination by the light means; and a sound generator adapted to be actuated by the sensor to emit sound which disguises or overrides the sound of the camera operation.
Claim 3
Dependent Claim
14 words
Intrusion detection means according to claim 1, wherein the sensor is an infrared sensor.
Claim 4
Dependent Claim
33 words
Intrusion detection means according to claim 2, further including an electronic logic board controlling the operation of the camera, light means and sound generator in response to signals received from the infrared sensor.
Claim 5
Dependent Claim
35 words
Intrusion detection means according to claim 3, wherein the logic board is set to control the sequence of operations such that the camera is triggered during operation of the light means and the sound generator.
Claim 6
Dependent Claim
35 words
Intrusion detection means according to claim 4, including a solenoid and associated plunger positioned to trigger the camera on energising the solenoid, the energising of the solenoid being under the control of the logic board.
Claim 7
Dependent Claim
28 words
Intrusion detection means according to claim 5, including a battery pack to power the light means, the sound generator and the sensor under control of the logic board.
Claim 8
Dependent Claim
13 words
Intrusion detection means according to claim 6, wherein the battery pack is rechargeable.
Claim 9
Dependent Claim
23 words
Intrusion detection device according to claim 7, further including a mains operated trickle charger, adapted to maintain the battery pack in charged condition.
Claim 10
Dependent Claim
20 words
Intrusion detection means according to claim 8, further including a visual indicator to indicate a prior operation of the camera.
Claim 11
Dependent Claim
21 words
Intrusion detection means according to claim 9, wherein the visual indicator is a light emitting diode connected to the logic board.
Claim 12
Dependent Claim
23 words
Intrusion detection means according to claim 1, further including an automatic telephone dialler actuated by the sensor to dial a predetermined telephone number.
Claim 13
Dependent Claim
19 words
Intrusion detection means according to claim 1, further including an enclosure for the camera constituting a visual disguise therefor.
Claim 14
Dependent Claim
35 words
Intrusion detection means according to claim 1, wherein the camera includes data and time recording facilities, to produce on the photograph a record of the time and date on which a given photograph was taken.
