2. General Description
The Videology Forensic Camera is a stand alone self contained video camera and recorder,
designed primarily for Forensic applications in which the stored video images are to be
viewed after an event.
The camera design can accommodate a variety of front end imaging devices, including CCD,
CMOS, Color or monochrome sensors. Wide dynamic range and true day night versions are
also available.
The camera records video onto and internal SD card, either continuously, according to a
pre-programmed schedule, or as a result of motion within the field of view.
Both the image resolution and the frame rate can be adjusted via software to give a wide
range of recording time.
The camera is powered from an external 12V DC power supply, (a battery back up will also
be available in the future).
A hardened version of the camera is also available, in which the internal memory device is
housed within a fire and blast resistant enclosure.
The camera is designed as a compact, self contained, low cost, easily installed video
surveillance device.
Applications include monitoring of mass transit vehicles, shopping malls, large public events
etc.

4. Video Recording
The camera stores compressed video either in full motion (MPEG4) or single frames (MJPEG)
onto an internal SD card.
Currently the size of the SD card is limited to 8 Gbyte, although larger capacity cards will be
supported in the future,
In the single frame capture mode, the camera can stored images at a maximum rate of one
frame per second.
With an 8 Gbyte card, this will provide for a maximum recording time of about 40 Hrs.
Increased recording times can be achieved by either reducing the resolution, or reducing
the frame rate.
The camera can be programmed to stop recording once the SD card is full, or to continue
recording by overwriting the oldest files first. In this way a continuous video loop is
maintained.
5. Camera Programming
The camera is equipped with an Ethernet port which can be connected directly to a PC for
the purpose of programming.
5.1. Mechanical
The dimensions of the camera (with hardened memory module) are shown below. Without
the hardened memory, the length is reduced to 75 mm.
