Meanwhile, the HDMI output can be used as SDI-HDMI convertor to output the SDI video to
the HD TV monitor.
2.3.6 Analog camera test
Display analog camera image ,4.3 inch 800×480 LCD screen display ,larger viewing angle ,more
intuitively and easily to display the camera image quality. Support PAL/NTSC format.LCD screen
backlight brightness adjustable, and analog video image brightness/contrast/color Saturation adjustable.
2.3.7 Video level meter*(optional)
The IP camera tester has adopted hardware high-speed sampling and processing technology, enables it
to achieve more accurate measurements in the video signal PEAK, SYNC level,
COLOR BURST chroma level
Video signal PEAK level: For PAL format , the video signal level is 1000±200mV
For NTSC format, the video signal level is 140±15IRE
If the level is too low, it will cause the image to dim and reduce dynamic range, but if the level is
too high, it will lead to virtual shadow and reduce the definition of the image.
SYNC level: by testing the amplitude of the video sync pulse to verify if the video level is correct and
the coaxial cable connectivity is good.
For PAL format, the SYNC level is 280 ± 35mV
For NTSC format, the SYNC level is 40 ± 5IRE
If the level is too low, it will cause the image to fracture or scroll, but if the level is too high, it will lead
to reduce the image’s color levels and dynamic range.
COLOR BURST chroma level: by testing the color burst level to estimate whether the coaxial cable is
the best to transmit the details and color.
For PAL format, the Chroma standard level is 280mV
