Recently, I bought 4 VM-99516 multi-sync 16 channel security camera multiplexers.

When it connected to the PAL CCTV camera, the pictures showed good on the monitor.

When it connected to the NTSC CCTV camera, the pictures show

blur. Adjusting the camera focus didn't help out the situation. Then, I connected the NTSC camera directly to the monitor, the picture was good.

Also, I did modify the multiplexer camera setting; such as, contast, sharpness and so on. The problem is still the same. Changed to other multiplexer, the problem is still the same too.

Any suggestion? Is the VM-99516 not compatible with NTSC cameras?

hengchan,

The VM-99516 16 channel CCTV multiplexer can support PAL or NTSC video modes. You can manually select which mode you want the multiplexor to run in my accessing the menu system, then selecting video system. Once the video system menu comes up you will see the following three options:
1. AUTO : Auto detects NTSC or PAL, ir channel 1 camera is connected
2. NTSC : Sets video system to NTSC mode
3. PAL : Sets video to PAL mode
If your multiplexor is set to auto and that is not working correctly, please select NTSC mode to manually set.

Please let us know if we can help further.
