To change the technology of Uniview 4N1 cameras, there are two methods depending on the camera model
Change from the camera's OSD menu
Change with 2 pins on one of the camera's cables
CHANGE WITH THE OSD MENU
This modification can be done with any XVR from any manufacturer as long as we are using the appropriate technology for each one, otherwise access may fail:
Safire/Hikvision: TVI
X-Security/Dahua: CVI
Uniview: TVI/AHD
IMPORTANT: If you change the technology to CVBS, the only way to access the OSD menu is through a Uniview XVR
CHANGE WITH THE CABLE PINS
In these cases, the camera will have a cable with 2 pins; depending on the position of these, one technology or another will be set
