I have 2 coaxial Hikvision external cameras working properly when connected to the DVR.
I'm trying to connect the DVR and/or the cameras to F441 module and see the image through Multimedia Touchscreen MH4893 and web access through atMyHome application.
The F441 has 2 EP connected and working properly. The images can be seen.
First trial #1
The cameras are connected to 347400 modules and these to F441. Both channels give black images in the touchscreen. It seems the 347400 is not converting the signal.
Second trial #2
The cameras are connected to the DVR. The DVR out connected to 347400 module and this to F441. The same problem: blackscreen in the domotic.
The cameras are powered directly with 12V and not by 347400. This is done in order to have the cameras fulltime recording to the DVR.
# Problem #
Only DVR image is possible to see. Blackscreens in the Legrand domotic system.
What could be the problem for this? Any suggestions or resolution?
