Thanks Dan,
Indeed I am looking for a guaranteed fix without risk of damage to the POE switch, or cameras and DVR for that matter.
For the price of SCK's "5 Port Gigabit Switch, Product #Switch-5G" I will consider it then to be very cost effective insurance! Thanks
Am I safe then to reason that it will be OK to add more transformer powered “IPPTZ-EL2MPL-12X-Mni-O” cameras into the "5 Port Gigabit Switch, Product #Switch-5G" later on with this?
Also, thanks for the link to the "How to Connect a Microphone to a Security Camera System" article. It is a big help.
However the article said "For our cameras at SecurityCameraKing.com, the only IP cameras that accept video are the ones listed in this illustration and the next one" and list "IPVD-EL3MPIR, IPBC-EL2MP, IPBC-EL3MP, IPOB-EL2MPIR50L3312, and for all IPPTZs.
I hope this article was prior to stocking the SIP-EMVD-21-4R camera, as it was advertised as microphone capable? It does have pigtails with audio in and audio out on the camera. So should it work with my FEo16480 Hybrid?
