I have an opportunity to bid on an installlation but I'm new to the camera side of IT. A couple questions: Mobotix advertises their great advantage is that their camera systems don't require any annual license renewal fee for operating management software because each camera uses a flash memory card at the camera. So does that mean most or all other camera systems do require a fee for software? It seems like a big selling factor. Am I missing anything? This job bid is for 30 cameras in a commercial building.
