  1. I have a indoor DAHUA VTH5221DW (https://dahuawiki.com/Video_Intercom/Products/DHI_VTH5221DW) and outdoor DAHUA VTO2111D-WP (https://dahuawiki.com/Video_Intercom/Products/DHI_VTO2111D_WP ). From the indoor unit I open remotely the e-lock...everything is great. My question: How can I use the indoor unit to open a automatic gate, because I see, it has the possibility to open 2 doors. Is the solution to use the switch DE1010B Access Control extension module, or how to do it the easiest way. The gate to open is a Beninca BULL624 TURBO engine.
  2. Where to install the isolator, direct to the DVR or to the CCTV camera...I guess Equipment means the Camera and Cable is the DVR?
  3. Thank you for your answer. Would this be the proper solution?
  4. 3A,12v adapter, normale coax cable and the distance is cca 30m. It worked fine for 2 years.
  5. The cameras are Dahua BNC, with new power adapters and both are on the same side of the house.
  6. I have 8 cameras, 2 of them have on the display (screen) horizontal flickering lines. Any idea what the cause is? Here is the video of the flickering horizontal lines: https://app.box.com/s/tiuxvi26e8x1eze5e44hapvm3as9i37v
