Tech Trends: SFP Finally Moving into Security

Small Form Factor Pluggable transceivers can change the way security video is transmitted

Next, it was with pleasant surprise that I spotted at the November Secured Cities Conference an IP video camera by TKH whose network interface is an SFP module, allowing a number of variations for the physical media. In the olden days of analog, companies built media converters into the camera housings — why has it taken this long for a camera company to embrace a built-in SFP port? Further, I spotted in their booth an SFP module with a BNC-pigtailed coax protruding to the side. They had actually engineered an IP-over-coax link into an SFP form factor. Makes me wonder about PoE…

So, 14 years after the introduction of this very useful and sensible communications technology, we are witnessing the broader adoption of this in security. At least we can be sure that the kinks have long been worked out. For my part, I’m hoping to see more application-specific innovation like that displayed by TKH.
