I run a small office network that uses TP-LINK T1600G-28TS (TL-SG2424) JetStream switches. The office is across two buildings, each fed by a different phase of power.
We've recently installed HD video feeds accross both buildings to power info screens - the source of this video is sat nicely in a server cabinet within building A, which is powered by a National Grid power feed (I'll call it feed A). The video is then sent around that building. Happy days.
We also need the video feed in building B, which is powered by a separate National Grid power feed (I'll call it feed B), despite the building being only 80m away. To carry the feed between the two buildings we use HDMI over CAT6 converters and just run it on a spare underground CAT 6 line.
I have an obvious problem of copper between two power sources. The HDMI over CAT6 RX/TX units are not isolated properly and keep blowing each other up.
My plan is to buy HDMI over TCP/IP, and run this through a VLAN on my switch. Am I correct in thinking that the Switch is isolated? I anticipate that the routing will be as follows:
- HD Video source (power feed A)
- HDMI over TCP/IP TX (power feed A)
- VLAN on TP-LINK T1600G-28TS (TL-SG2424) JetStream (power feed A)
- VLAN on TP-LINK T1600G-28TS (TL-SG2424) JetStream (power feed B)
- HDMI over TCP/IP RX (power feed B)
- HD monitors in building B (power feed B)
I hope this avoids an non-isolated copper connection between power sources. Thoughts and comments?
Obviously the easy way to do this is via a fibre video link. I've thought about it, but this is about 1/10th of the price.
