Abstract

A automatic surveillance camera equipment contains an infrared ray detecting sensor having a plurality of sensing zones and for detecting an intruder within a watching area and transmitting its signal to a control device, a control device for sending a command signal to a camera unit in response to the signal from the infrared ray detecting sensor, a camera unit for supplying a response signal to a camera in response to the command signal from the control device, a camera for synchronizing a strobe and a camera shutter each other by the response signal from the camera unit, automatically shooting, and automatically rewinding a film simultaneously together in a protective case, and is intended to perform photography of an intruder on each of the sensing zones of the infrared sensor when the intruder enters the watching area. An alarm system is directly communicated to the outside through a telephone line to transmit a signal.

Claims

1. An automatic surveillance camera equipment, comprising:

an infrared ray detecting sensor having a plurality of sensing zones, and which transmits a signal to a control device each time an intruder enters one of said sensing zones;

a control device for sending a command signal to a camera unit in response to the signal from the infrared ray detecting sensor;

a camera unit for supplying a response signal to a camera in response to the command signal from the control device;

a camera for synchronizing a strobe and a camera shutter with each other by the response signal from the camera unit, automatically photographing the intruder, and automatically rewinding a film simultaneously; and

a protective case for accommodating the infrared ray detecting sensor, the control device, the camera unit and the camera together,

whereby the equipment photographs an intruder in each of the sensing zones of the infrared ray detecting sensor when the intruder enters the sensing zone.

2. An automatic surveillance camera equipment according to claim 1, further comprising a built-in battery which operates automatically when a power supply from outside stops.

3. An automatic surveillance camera equipment according to claim 1, wherein a film is automatically rewound when another film is loaded in the camera, and said exposed film is automatically held into a patrone.

4. An automatic surveillance camera equipment according to claim 1, wherein a threatening alarm bell operates simultaneously when an intruder enters a watching area.

5. An automatic surveillance camera equipment according to claim 1, further comprising a vibration sensor and a threatening alarm bell which are operative when an intruder touches said protective case.

6. An alarm system, comprising

an infrared ray detecting sensor having a plurality of sensing zones, and which transmits a signal to a control device each time an intruder enters one of said sensing zones;

a control device for sending a command signal to a camera unit in response to the signal from the infrared ray detecting sensor;

a camera unit for supplying a response signal to a camera in response to the command signal from the control device;

a camera for synchronizing a strobe and a camera shutter with each other by the response signal from the camera unit, automatically photographing the intruder, and automatically rewinding a film simultaneously;

a protective case for accommodating the infrared ray detecting sensor, the control device, the camera unit and the camera unit together; and

a transmitting means for directly sending a signal from the infrared ray detecting sensor to the outside through a telephone line,

whereby the camera photographs an intruder in each of the sensing zones of the infrared ray detecting sensor when the intruder enters the sensing zone.

7. An automatic surveillance camera equipment according to claim 6, further comprising a vibration sensor and an alarm bell which are operative when an intruder contacts said protective case.

8. An automatic surveillance camera equipment, comprising:

an infrared ray detecting sensor having a plurality of sensing zones, and which transmits a signal to a control device each time an intruder enters one of said sensing zones;

a control device for sending a command signal to a camera unit in response to the signal from the infrared ray detecting sensor;

a camera unit for supplying a response signal to a camera in response to the command signal from the control device;

a camera for synchronizing a strobe and a camera shutter with each other by the response signal from the camera unit, automatically photographing the intruder, and automatically rewinding a film simultaneously;

a protective case for accommodating the infrared ray detecting sensor, the control device, the camera unit and the camera together, and

a battery provided in said protective case for supplying power to said camera surveillance equipment when external power is interrupted,

whereby the camera photographs an intruder in each of the sensing zones of the infrared ray detecting sensor when the intruder enters the sensing zone.
