Hi Friends,
I am facing a problem at one of my site which is in a remote area around 300 Kms from Mumbai. If any of you could help me with the solution it would be very grateful.
• I have installed a 32 Channel DAHUA DVR with 24 1MP Dome and Bullet Cameras.
• The DVR is installed in a DVR Rack in Server Room.
• The VGA output is connected to a Local Samsung 22” Monitor with a Wireless Mouse.
• The HDMI output is extended to the Director’s Cabin using a 60 Meter HDMI extender through a Cat6 Dlink Cable of 48 meters. Connected to another Samsung 22” Monitor.
• The USB port is extended to the Directors Cabin through a Cat6 Dlink Cable of 48 Meters. And is connected with a normal USB mouse.
The whole systems is working beautifully.. Both screens and mouse working at server room and director’s cabin
NOW… The problem ..
Whenever someone turns ON / OFF any fan in the whole building, the screen at the Directors goes OFF for 2 seconds and then comes back ON.
It also happens if we change the speed of fan with regulator. The regulators are of hard switch type with fixed speeds[1,2,3,4,5,0] (Not variable type)
Nothing happens if we switch ON / OFF any other light switch or Desktop PC etc.
There is Single phase in the building. The earthing is properly buried in the ground.
Experiments already done … with same results
• Bypassed the Fan switch, regulator.
• Changed Cat6 Cables, HDMI Cables / VGA Cables.
• Changed HDMI Extenders
• Tried with VGA Extenders
• Shortened the length of 48 Meters to 10 meters
• Tried connecting 2.2MF Capacitors with Extender’s Power Supply to suppress any pulse.
• Changed Samsung Monitor with Acer Monitors.
CAN SOMEONE HELP ME OR EXPLAIN ME ABOUT SOLUTION TO THIS PROBLEM..
