Abstract: A device for tensioning a belt of a video camera assembly, including a belt tensioner terminal and an elastic thrust element operating on the belt tensioner terminal for thrusting the belt tensioner terminal against the belt. The device further includes an adjustment element for determining an adjustable positioning of the belt tensioner terminal with respect to the belt and at least one constraint element for operating between a rest condition, where it does not constrain the positioning of the belt tensioner terminal, and a constraint condition, where it constrains in position the belt tensioner terminal. The adjustment element is operatively connected to the thrust element in a removable way. Advantageously, the thrust element and the adjustment element share a same operative direction, the at least one constraint element operating or developing along a direction which is orthogonal to said operative direction of the thrust element and of the adjustment element.

Abstract: A video camera assembly, includes a movable body to house a video camera and coupled in a rotatable manner to a base body. The base body has a cavity with a base portion of the base body and a closing wall which has a seat defining a through hole. The cavity houses a shaft on the first end of which the movable body is mounted, said first end of the shaft passes through the through hole of the closing wall and is coupled to the through hole by means of a first bearing inserted in the seat. The end of the shaft opposite to the first end is supported by a rolling type second bearing, and is connected to the base body. The second bearing is inserted in an annular seat made of material which projects from the base portion of the cavity towards the closing wall.

Abstract: The present invention relates to a method for controlling the transfer of data packets in an IP network. A device transmits a plurality of data packets in the IP network that are received by a switch on an input port. The switch analyses the data packets received by the device and extracts information identifying the type of device connected, and on the basis of this information, identifies in an internal memory area the criteria for setting the operating parameters of an application software executed by the device. The switch provides the device with operating parameters that are calculated on the basis of the criteria contained in the memory area such that the device subsequently executes the application software using the values provided by the switch.

Abstract: The present invention relates to a power supply system for video cameras (2) and for protection cases (1) for video cameras. The system comprises a first device (13), called as powered device since it receives power from a remote device, able to split a supply voltage (131) and a data signal (130) from a power supply input line (18). A plurality of power supply lines (14a-14e) are connected to a first output of the powered device (13) and they supply a plurality of electric components (7,8,9,10) via the supply voltage (131) extracted by the powered device (13). The system further comprises a power supply equipment (19) connected to the powered device (13) so as to receive as input the supply voltage and the data signal split by the powered device. A case and a method for powering a video camera are also described.

The device (3) comprises a first port (403) for the connection to a remote terminal (4), a second port (503) for the connection to a video camera (1), a third port (603) for the connection to a positioning unit (2) for the video camera (1), and a microprocessor circuit (703) operatively connected to said three ports for transferring the commands received through the first port (403) to the second port (503) and/or to the third port (603).

Abstract: Method for coordinating a plurality of sensors, wherein a plurality of networked computers control the sensors for the purpose of executing one or more services requested through the network. In order to coordinate with one another, the computers exchange information over the network in a manner such that each networked computer knows the characteristics of and the services executed by the other computers. Subsequently, the computers providing the same service execute the same configuration algorithm that defines the tasks to be carried out by each computer as a function of the characteristics of the computers providing said same service. Thus, the computers get to the same conclusions as to the tasks to be carried out, and control the sensors based on the tasks defined by the configuration algorithm.

Abstract: The invention relates to a method for monitoring an environment through a plurality of sensors, wherein a control system receives information from one or more sensors of said plurality and uses said information in order to monitor said environment. The method comprises a setup stage wherein an operator creates a model of an environment by defining a plurality of cells corresponding to areas of said environment, and then creates cell/sensor relationships by defining for each sensor at least one possible position which is associated with at least one cell. For each position the sensor is assigned by the operator a monitoring judgment for the associated cell. The method also comprises an operational stage wherein the control system, in order to perform a surveillance function, finds those sensors which can be used for carrying out the requested surveillance function and controls them based on the monitoring judgments and the cell/sensor relationships.
