Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed.

Compact radio frequency antenna apparatuses

Radio devices for wireless transmission including an integrated adjustable mount allowing mounting to a pole or stand and adjustment of the angle of the device (e.g., the altitude). The device may include a compact array antenna having a high gain configured to operate in, for example, the 5.15 to 5.85 GHz band and/or the 2.40-2.48 GHz band. The antenna emitters may be arranged in a separate plane from a plane containing the antenna feed connecting the emitting elements and also from a ground plane. The antenna array may be contained within a protective weatherproof housing along with the radio control circuitry.

One embodiment of the present invention provides a cloud-based video monitoring system comprising a camera and a network video recorder (NVR). During operation, the camera stores in a buffer last predetermined temporal segment of a video. The camera also stores a first video file in a local storage corresponding to an event detected by the camera. This first video file is non-overlapping with a second video file corresponding to the event and this second video file is stored in the NVR. The camera generates a third video file by pre-pending last predetermined temporal segment of a video prior to the event to the first video file and sends the third video file to the NVR.

Cloud-based video monitoring

Multiple panel reflector dish antenna

Devices and systems, and methods of using them, for point-to-point transmission/communication of high bandwidth signals. Radio devices and systems may include a pair of reflectors (e.g., parabolic reflectors) that are adjacent to each other and configured so that one of the reflectors is dedicated for sending/transmitting information, and the adjacent reflector is dedicated for receiving information. Both reflectors may be in a fixed configuration relative to each other so that they are aligned to send/receive in parallel. In many variations the two reflectors are formed of a single housing, so that the parallel alignment is fixed, and reflectors cannot lose alignment. The device/systems may be configured to allow switching between duplexing modes. These devices/systems may be configured as wide bandwidth zero intermediate frequency radios including alignment modules for automatic alignment of in-phase and quadrature components of transmitted signals.

Radio system for long-range high-speed wireless communication

Shroud isolation, including choke shroud isolation, apparatuses for wireless antennas for point-to-point or point-to-multipoint transmission/communication of high bandwidth signals, and integrated reflectors including a shroud or choke shroud. A choke shroud systems may include a cylindrical body with an isolation choke boundary at the distal opening to attenuate electromagnetic signals to, from, or within the antenna. The isolation choke boundary region may have ridges that may be tuned to a band of interest. The isolation choke boundary may provide RF isolation when used near other antennas.

Antenna isolation shrouds and reflectors

Apparatuses that operate as both a public address speaker and a wireless access point (AP) for mounting to a ceiling or wall. The compact public address access points described herein may include an AP housing, enclosing a radio (e.g., a 3&#xd7;3 MIMO radio) and antenna, that is coupled to a speaker assembly including a speaker, a conical acoustic reflector positioned between a front of the speaker and the housing of the AP, and an annular region comprising a concave inner wall facing the conical acoustic reflector. Although the AP is nested atop the front of the speaker, the speaker may produce high-quality sound with accurate voice reproduction without interfering with the operation of the wireless transmission of the AP. Methods of operating and installing these apparatuses are also described.

Compact public address access point apparatuses

One embodiment of the present invention provides a radio assembly. The radio assembly includes an antenna housing unit that houses a pair of reflectors which are situated on a front side of the antenna housing unit, a printed circuit board (PCB) that includes at least a transmitter and a receiver, and a backside cover. The PCB is situated within a cavity at a backside of the antenna housing unit and the backside cover covers the cavity, thereby enclosing the PCB within the antenna housing unit. One embodiment of the present invention provides a user interface for configuring a radio. The user interface includes a display and a number of selectable tabs presented on the display. A selection of a respective tab results in a number of user-editable fields being displayed, thereby facilitating a user in configuring and monitoring operations of the radio.

Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed. Also described herein are compact RF antenna devices having a lightpipe that passes through the single patterned emitting surface.

Various embodiments of antenna assemblies are disclosed herein. In one embodiment, the antenna assembly includes a reflector comprising a center opening, a feed-antenna subassembly situated in front of the reflector, a rear housing situated behind the reflector, and a pole-mounting bracket comprising a base plate situated between the reflector and the rear housing. The feed-antenna subassembly comprises a feed tube that houses at least one of: a transmitter circuit and a receiver circuit. The rear housing is coupled to a front side of the reflector via the center opening. The rear housing comprises a center cavity, and a back end of the feed tube is inserted in and coupled to the center cavity. The base plate is coupled to the reflector and the rear housing in such a way that decoupling between the base plate and the reflector requires a prior decoupling between the feed-antenna subassembly and the rear housing and a prior decoupling between the rear housing and the reflector.
