Besides, it's nothing I couldn't have accomplished without some
well-placed board cameras.
Board cameras, also commonly called printed circuit board (PCB)
cameras, are a type of small-footprint video camera that are valued for their
general versatility. With optical devices and image sensors mounted directly on
a circuit board, manufacturers are able to sacrifice components to provide
a space-saving design. Cellular phones and surveillance systems are
the most prominent employers of board cameras.
Yes, a few board cameras in the rooftops of Gotham Tower,
and I suppose just anyone could watch Mr. Wayne's nightly activities.
cameras are a type of digital camera that have their optical recording
devices--aperture, lens, and image sensor--directly attached to a printed
circuit board with typical input/output. As such, most board cameras are small
in size-registering just 1/3" in lens
diameter. CCD image
are most common, but CMOS and CID sensors are
used as well. Without a specified feature, board cameras retain the
functionality of video cameras in general. It is recommended you visit

display of a board camera is relayed through the I/O of the PCB, typically a
display or handheld monitor. Since there are no analog controls, recording
options are also controlled through this interface. Attached to a programmable
logic controller, board cameras can act as a type of vision system.
With the camera directly mounted onto the printed circuit
board, and the small footprint of these cameras overall, mounting options for
board cameras are limitless. Board cameras for surveillance are
placed surreptitiously to record unaware subjects. This includes clocks,
toys, mirrors, and other hidden camera applications. Board cameras are also
commonly used in cell phones, tablet computers, and other mobile devices. Board
cameras do not have a common mounting option, such as brackets or
stands. Board cameras often incorporate a form of electromagnetic
shielding in their housing. This prevents interference from nearby electrical

the camera in your iPhone (yes, even super villains use iPhones), examine
