Abstract: A local area data network (26) interconnects devices (12, 14, 20, 30) which make up a video surveillance system (10). The devices attached to the local area network are divided into distinct classes (12, 14, 30) which are polled with different degrees of frequency. Devices are dynamically reassigned from class to class depending on each device's current requirements for network access. Group polling is also employed, with resolution of contention by means of a probing algorithm. Negative responses to polling messages are formed as a series of line transitions that require less time than transmission of a single data byte. Polling messages have a distinct length in terms of bytes that is shorter than any other message transmitted on a network. Polled devices (12, 14) are permitted to transfer data directly to peer devices in response to polling messages.

Abstract: A surveillance camera assembly housing (28) is releasably locked to a base (24) for the housing. The base is installed in a ceiling or at another location remote from ground level. A removal tool (22) provided at the end of a pole (136) has fingers (36) which are inserted into apertures in the assembly housing. The tool engages the assembly housing by means of the fingers, while also being operated to release a mechanism which secures the housing to the base. The housing, now secured to the tool, is removed from the base and brought to ground level. In this way, removal of the surveillance camera is accomplished without resort to ladders or scaffolding.

Abstract: A video surveillance system (10) has a camera equipped with a fisheye lens (20) having a substantially hemispheric field of view. The system implements operations equivalent to the panning, tilting and zooming of a conventional camera without the use of moving parts. The lens (20) is mounted vertically above a plane under surveillance. The camera produces a fisheye image (14) made up of a plurality of pixels. The fisheye image (14) is distorted due to the properties of the fisheye lens (20). The system corrects the distortion by mapping the pixels of the fisheye image (14) to coordinates produced by selecting a particular part of the fisheye to be viewed.

Abstract translation: 视频监视系统（10）具有配备有具有大致半球场的鱼眼镜头（20）的相机。 该系统在不使用移动部件的情况下实现与常规相机的平移，倾斜和变焦相当的操作。 透镜（20）垂直地安装在被监视的平面上方。 相机产生由多个像素构成的鱼眼图像（14）。 鱼眼图像（14）由于鱼眼镜头（20）的特性而变形。 系统通过将鱼眼图像（14）的像素映射到通过选择要观察的鱼眼的特定部分产生的坐标来校正失真。

Abstract: A video surveillance system (10) has a camera equipped with a fisheye lens (20) having a substantially hemispheric field of view. The system (10) implements operations equivalent to pan, tilt, and zoom of a conventional camera. The camera produces a distorted fisheye image due to the properties of the fisheye lens (20). The system (10) corrects the distortion by mapping the pixels of the fisheye image to coordinates produced by selecting a particular part of the fisheye image to be viewed. The fisheye image formed by the camera is split into four separate image components (15, 16, 17, 18) carried by four bundles of optical fibers (35, 36, 37, 38). Each bundle has a CCD (45, 46, 47, 48) and associated image processing circuitry (65, 66, 67, 68) which forms an electronic representation of the image component carried by that bundle.
