Product Department Notes:
"For all the SCC series 4in1 cameras, the output signal(TVI/CVI/AHD/960H) can only be switched by the dip switch when the current resolution is on default.
8MP Coax default resolution is 8MP
5MP Coax default resolution is 4MP
2MP Coax default resolution is 2MP"
What this means is that when you have a 5MP SCC model, you must drop the camera to 4MP resolution. When you do this, the signal switch will function. When in 5MP mode, the signal switch button is not active.
