## Abstract

A camera apparatus includes a pan tilt drive device; a pan controller that performs rotation angle control on a pan motor which is provided in the pan tilt drive device; a tilt controller that performs rotation angle control on a tilt motor which is provided in the pan tilt drive device; a mechanical endpoint detection sensor that outputs a mechanical endpoint of a physical rotation direction of the pan tilt drive device; a storage that stores a turning range for each installation posture as a turning range angle from the mechanical endpoint; and a CPU that sends out a start endpoint angle and a terminal endpoint angle of the turning range angle which is read from the storage according to the installation posture to the pan controller and the tilt controller.

## Claims

### Claim 1

A camera apparatus comprising:
a pan rotation driver that is supported by a housing main body, and is configured to perform pan rotation by a pan motor;
a tilt rotation driver that is configured to include a capture, is supported by the pan rotation driver through an arm, and is configured to perform tilt rotation by a tilt motor;
a pan controller that controls a pan rotation angle of the pan rotation driver;
a tilt controller that controls a tilt rotation angle of the tilt rotation driver;
a position detection sensor that detects an endpoint of a physical rotation direction of the tilt rotation driver;
a storage that stores a turning range in a tilt rotation direction for each posture as an angle which indicates the turning range from the endpoint; and
a controller that controls the tilt rotation angle by sending out a start endpoint angle and a terminal endpoint angle of the angle, which indicates the turning range stored in the storage, to the tilt controller according to the posture of the tilt rotation driver.

### Claim 2 (depends on 1)

The camera apparatus of claim 1,
wherein the storage stores preset information, which indicates angle information of a predetermined direction viewed from the camera apparatus, as a preset angle based on the endpoint, and
wherein the controller converts the preset angle into a changed preset angle corresponding to each posture, and sends out the changed preset angle to the pan controller and the tilt controller for setting.

### Claim 3 (depends on 1)

The camera apparatus of claim 1,
wherein the storage stores a mask area, which is used such that a part of image data imaged by the capture is not displayed, as a mask range angle based on the endpoint, and
wherein the controller converts the mask range angle into a changed mask range angle corresponding to each posture, and sends out the changed mask range angle to the pan controller and the tilt controller for setting.

### Claim 4 (depends on 1)

The camera apparatus of claim 1, further comprising:
a washing water injection device that washes a front cover of the tilt rotation driver,
wherein the storage stores a washing position of the front cover of the tilt rotation driver, which is washed by the washing water injection device, as a washing position angle based on the endpoint, and
wherein the controller sends out the washing position angle to the pan controller and the tilt controller for setting according to a washing manipulation from a user.
