GT-CH21C3-28VFW
2/6
Megapixel camera with 1/2.9" Sony CMOS sensor and AHD
/ HD-CVI / HD-TVI / PAL.
The AHD / HD-CVI / HD-TVI interface allows to
transmission of analog video signal via coaxial cable in
1080p resolution. It enables the transmission of HD
resolution images for even 500 m distance with keeping the
low costs of the installation. During transmission there are
no delays and is maintained the original, high quality
image.
Setting the camera in PAL mode allows to obtain an image
in 960H resolution. The appropriate signal format selection
is done by tilting and holding the joystick for 5 s without
entering to the OSD menu. Changing the signal to the
NTSC in the camera causes loss of image in connected
AHD/HD-CVI/HD-TVI recorder.
