  • Publication number: 20240236483
    Abstract: A surveillance camera system includes a power sourcing equipment corresponding to a midspan having one or more of integrated input/output (I/O) and audio port functionality, the power sourcing equipment including processing circuitry, one or more data ports, one or more of an I/O port and an audio port, and a Power over Ethernet (PoE) port. Additionally, the surveillance camera system includes a camera connected to the power sourcing equipment by the PoE port, and a computer connected to the power sourcing equipment by one of the data ports, wherein the computer is configured to receive data from and transmit data to the camera via the power sourcing equipment.

  • Patent number: 11965915
    Abstract: Herein is provided a device for optimizing bandwidth during oscilloscope measurements. The device is connectable to a probe for electrically connecting a test point and an oscilloscope. The device may include at least two grounding connectors with different inductances for electrically connecting ground to the probe and a tuning network comprising circuitry configured to compensate for the different inductances of said at least two grounding connectors, the tuning network being switchable between different modes, each mode being configured to compensate for a specific inductance of said at least two grounding connectors. A method for optimizing bandwidth during oscilloscope measurements is also provided.
