Abstract:
A pin header connector includes a number of electrically conductive pins, two insulating plates, and a supporting body. The pins are arranged in two parallel rows. Each of the rows comprises at least three pins. Each of the insulating plates defines a number of through holes corresponding to the pins. Each of the pins extends through the corresponding through hole. The supporting body defines slots accommodating the respective pins. The supporting body is sandwiched between the insulating plates.
Abstract:
A delay circuit used in a schedule controller includes a voltage detection unit, a timer, and a first electronic switch. The voltage detection unit receives an input voltage and compares the input voltage with a predetermined voltage. The timer is controlled by the voltage detection unit to calculate duration of an interval time. The first electronic switch is switched on or off under the control of the timer. When the input voltage substantially equals or exceeds the predetermined voltage, the timer calculates duration of the interval time, the timer generates and transmits a switch signal to the first electronic switch when the timing is reached, and the first electronic switch is switched on by the switch signal and provides an output voltage.

Abstract:
A filter conversion device includes a first filter, a second filter, a motor, and a microswitch. The motor moves the first or second filter according to a control signal from a processor of the camera. The micorswitch is mounted adjacent to the first filter. A first terminal of the microswitch is grounded. A second terminal of the microswitch is connected to a power supply with a resistor and is connected to the processor of the camera with a connector. When the first filter contacts the microswitch, the microswitch turns on.
Abstract:
A power supply circuit for an infrared cut removable (ICR) filter includes an identifying module, a supply mode module, a switching module, and a power source module. The identifying module generates a first identifying signal when the brightness of external light is higher than a preset brightness; otherwise, the identifying module generates a second identifying signal. The supply mode module generates a power supply corresponding to the power supply mode of the ICR filter. The switching module includes two connecting nodes for connecting to the ICR filter and loads the power supply generated by the supply mode module on one of the nodes correspondingly according to the first and second identifying signals. The power source module is connected to an external DC power supply and generates an operating voltage for the identifying module, the supply mode module, and the switching module.
Abstract:
An iris calibration device includes one or more groups of light sources, a microcontroller (MCU), and a display. The MCU connects to a system on chip (SoC) of a digital camera device. The digital camera device includes an iris lens. The MCU receives an “on” command or an “off” command from the SoC. The MCU turns on or turn off a group of light sources according to the “on” command or the “off” command The SoC adjusts the iris lens according to an average luminance of the one or more light sources sensed by a sensor of the digital camera device.
Abstract:
An Internet Protocol (IP) camera management system and method determines a MAC address of an IP camera corresponding to a communication channel, searches an IP address of the IP camera through the determined MAC address of the IP camera, then establishes connection between the IP camera management system and the IP camera through the searched IP address. Furthermore, video image data are acquired from the IP camera through the communication channel and are displayed on a display interface.
Abstract:
A master-slave communication circuit includes a master device, a number of slave devices, and a bus providing communication channels between the master device and the slave devices. Each slave device includes an identification (ID) address setting unit, a plug-in detecting pin, and a plug-out detecting pin. The identification (ID) address setting unit is connected to the bus to receive an ID address setting signal transferred from the master device, and set an ID address to the corresponding slave device. The master sets the ID addresses of the slave devices according to voltage levels of the plug-in detecting pin and the plug-out detecting pin, to make the ID addresses of the slave devices connected to the bus are different.
