Abstract: A projection screen system includes a housing defining a channel, a screen and motor assembly including a projection screen and a tubular motor, and first and second opposed mounting features configured to hold the screen and motor assembly in the channel of the housing. The housing is configured to be installed recessed in a ceiling and the screen and motor assembly is configured to be mounted in the housing of the installed housing such that the installation of the housing and the mounting of the screen and motor assembly are performed independently.

Abstract: A surveillance camera includes a primary power connection for electrically connecting the camera to a primary power source. The camera includes a housing and a test port in the housing. The test port includes a port connection for electrically connecting the camera to a secondary local power source such that the camera receives power from the secondary power source. The port connection is further for connecting the camera to a portable monitor such that video from the camera is displayed on the monitor when the camera is electrically connected to the secondary power source independent of whether the camera is electrically connected to the primary power source.

Abstract: A rack includes a base resting on a horizontal surface, a top and four elongated legs. Each leg includes a bottom portion pivotally connected to the base and a top portion pivotally connected to the top. The rack is movable between a flat position, wherein the legs are substantially parallel to the horizontal surface, and an upright position, wherein the legs are substantially perpendicular to the horizontal surface.

Abstract: An equipment box assembly includes an open-ended housing and a support plate. The housing has a back wall and opposed sidewalls defining a cavity in the housing. The back wall includes a plurality of mounting features for mounting electronic components to the back wall. The housing is configured to be positioned in an installed position in a mounting surface such that the cavity is recessed in the mounting surface. The support plate includes a plurality of mounting features for mounting electronic components to the support plate. The support plate is releasably mounted in the housing cavity in a first position with the support plate generally parallel to and spaced apart a first distance from the back wall.

Abstract: A power conditioner assembly includes: first and second brackets and a power conditioner. Each bracket includes a rear portion adapted to attach to a rear portion of an equipment rack and a front portion that extends frontwardly. The power conditioner includes a housing having a rear panel, a first side panel mounted to the first bracket and a second, opposed side panel mounted to the second bracket. The power conditioner is mountable to the brackets in a plurality of orientations including: a rearward orientation with the rear panel oriented substantially vertically; and at least one angled orientation with the rear panel at an oblique angle to vertical. The brackets may also be adapted to attach to other mounting surfaces and/or other brackets may be provided for this purpose to provide additional mounting options.

Abstract: A tilt head mechanism for use with a display device includes a base plate member configured to connect to a vertical mounting structure or surface and an adapter plate member operatively connected to the base plate member. The adapter plate member has a front surface configured to connect to a display device, and the front surface has a center point. The adapter plate member is independently: movable horizontally away from and toward the base plate member; and tiltable downwardly and upwardly relative to the vertical mounting structure or surface, wherein the front surface center point of the adapter plate member does not move substantially horizontally as the adapter plate member is tilted relative to the vertical mounting structure or surface.
