Input Power
Included with the Photon camera is an AC/DC converter that generates 8VDC input power from
110 VAC or 220 VAC. If you prefer to provide your own power supply, please verify that the
input power at the camera connector meets the specifications shown in Table 3 when applied
across PWR_IN and GND pins.
CAUTION: Reversing polarity of input power will damage the camera’s internal power supply
and repair is not covered under the camera warranty.

at start-up 4000 mW Assuming no load between
HTR and HTR_RTN.
Analog Video Output
The video output of the Photon camera can be configured to either NTSC or PAL-compatible.
*
In either case, the output is intended to drive a 75-ohm load. Use of coaxial cable with 75 ohm
characteristic impedance is strongly suggested. The analog video signal is across the
VIDEO_LO and VIDEO_HI pins. See Table 4 for a list of other relevant video parameters.

Note: To use the Photon Isotherm option, the video monitor must be color capable. For display
of Photon video without Isotherm capability, a monitor complying with the monochrome-
equivalent standard shown in Table 4 can be used.
*
NTSC is the U.S. standard for color analog video. PAL is the European standard.
