Description



NOTE:

The 100% compatibility rate of the image display refers to the guaranteed compatibility when using simulation mode,and purchasing/setting errors can also be achieved by switching to CVBS/Analog mode first, starting the camera, and then opening the camera menu through the button to adjust the resolution/frame rate

Normally, as long as your DVR supports coaxial AHD/CVI/TVI mode, the camera will be compatible AHD/CVI/TVI .

(Please select the camera pixel with the maximum resolution supported by your AHD DVR.Otherwise, only analog mode can be used)

If you only have analog DVR/ NO DVR and only have a TV, then you need to use analog mode to achieve compatibility (=100%), But the Analog mode has differences in clarity to coaxial AHD/CVI/TVI

The default camera mode is AHD camera (applicable to AHD DVR),
Therefore, if your system is HD-TVI/CVI, please first adjust the camera to the same mode through the OSD button, otherwise the image may not be displayed or the image quality may be poor
(960H/CVBS/TV/MINI display screen must have no image, you need to power on and hold down the right side for about 20 seconds to change CVBS/Analog)
 

1) Press and hold the OSD button on the right for 20 seconds to switch to analog/CVBS

2) Press and hold the OSD button on the upper side for 20 seconds to switch to AHD
3) Press and hold the OSD button on the left for 20 seconds to switch to HD CVI
4) Press and hold the OSD button on the lower side for 20 seconds to switch to HD TVI
