Abstract:
The present invention provides a video surveillance apparatus and method of operation for a system having at least one predefined setting. A first parameter corresponding to an alignment of a video camera assembly with a visual target is stored. A second parameter corresponding to the alignment of a modified video camera assembly with the visual target is obtained. A difference between the first and second parameters is determined. The difference is applied to at least one of the predefined settings.
Abstract:
A pressure equalizing housing may be used to house equipement (e.g., one or more mechanical and/or electronic devices). The pressure equalizing housing may include a pressure equalization device to provide pressure equalization between an internal pressure inside of the housing and an ambient pressure outside of the housing. The pressure equalization prevents relatively humid air outside of the housing from passing into the housing and thus prevents or substantially minimizes condensation inside of the housing.

PROBLEM TO BE SOLVED: To provide a method of improving the speed of downloading a control command and data on a video dome, a switch, recording medium and another video monitoring system device via a transmitting medium. SOLUTION: A system and a method of controlling a video camera is constituted in such a way that it includes a step 604 of transmitting the command data to a video apparatus being able to be controlled via a transmission medium during a vertical blanking period of the video signal, a step 606 of receiving the command by the controllable video apparatus, and a step 608 of transmitting response data in response to the command data from the video apparatus being able to be controlled via the transmitting medium during the vertical blanking period. Using a coding format using data having a narrow bit width in UTC protocols enables a long propagation delay without generating errors due to interference, and the length of the transmitting medium in a system is prolonged.

PROBLEM TO BE SOLVED: To provide a system and a method which includes a polarity controller and a reverse circuit and automatically corrects wrong polarity in a communication signal. SOLUTION: The system is provided with a video camera 14, camera controller 20 for controlling the video camera, transmission medium for communicating at least one polarity-sensitive signal between the video camera and the camera controller, polarity controller 12 for detecting the wrong polarity in the polarity sensitive-signal and supplying a reverse signal in response to the wrong polarity, and at least one polarity correcting circuit 22, 24 provided with a reverse circuit for reversing the wrong polarity in response to the reverse signal. Also, a circuit for correcting wrong wiring in transmission and reception connection is provided. This circuit is provided with a controller constituted so as to detect wrong connection of an input signal to at least one transmission terminal, responds to the wrong connection and supply at least one exchange signal, and a reverse circuit for responding to an exchange signal and exchanging a reception terminal and a transmission terminal.

Abstract:
The present invention provides a video surveillance system, having a video camera; a motor operable to move the video camera; and a processor monitoring a value of a signal provided to the motor, the processor terminating the signal to the motor when the monitored signal value exceeds a predetermined value for a predetermined period of time. A network may be coupled to the processor for communication of the signal termination. The processor may reinitiate a signal transmission to the motor sufficient to maintain a position of the motor after a predetermined period of time, and the processor may monitor the signal transmission and adjust at least one of a zoom setting and focus setting of the video camera based at least in part on the monitored signal.
Abstract:
The present invention provides a system and method for controlling a motor in a video surveillance system including a video camera, a tilt motor operable to move the video camera in a tilt direction, a pan motor operable to move the video camera in a pan direction, and a controller in electrical communication with the tilt and pan motors. The controller assesses an operational condition of the video surveillance system and, if the assessment is successful, actuates at least one of the tilt motor and pan motor to move the video camera along a first predetermined motion pattern. In addition, if the assessment is unsuccessful, the controller actuates at least one of the tilt motor and pan motor to move the video camera along a second predetermined motion pattern.
Abstract:
The present invention provides a method and system that improve the low-speed control stability of a video camera assembly, including a video camera, a tilt motor operable to tilt the video camera and a pan motor operable to pan the video camera. A first encoder is coupled to one of the tilt motor and pan motor. The first encoder outputs a plurality of signals having corresponding signal edges, based on a rotation speed of the one of the tilt motor and pan motor. A first controller is in electrical communication with the first encoder. The first controller determines a speed of the one of the tilt motor and pan motor at least in part by correlating a time period between detection of the first edge and detection of the second edge to the speed of the at least one tilt motor and pan motor.
Abstract:
A dehumidified equipment housing may be used to house equipment including one o more mechanical devices and/or electronic devices. The dehumidified equipment housing may prevent condensation on one or more regions inside of the housing and may control condensation inside of the housing to provide a dehumidified environment inside of the housing. The dehumidified equipment housing may also remove condensed water to outside of the housing.
Abstract:
The multiple image video surveillance camera system that uses a common set of sequencing logic to sample multiple imaging devices or multiple pre-set image windows within a large high-resolution imaging device is provided (32, 34 of fig. 2). The images are multiplexed into a single frame or switched on a frame-by-frame basis at the imaging device. The switched frames are marked or encoded (36 of fig. 2) to facilitate separation for individual image display. This configuration allows one camera processor or sequencer to support multiple imagers and eliminates the need for a separate multiplexer, which lowers the system cost. Using a single transmission media (36 of fig. 2) to the video recording or display devices significantly reduces system installation cost.
