I never imagined "this" can work as a camera testing equipment!
Phil is an engineer working in the surveillance system installation industry. Installers like him need to test cameras in the field on a regular basis. He was seeking a convenient and cost-effective way to test the IP cameras.
We figured out the core of Phil’s problem was that he badly needed a mini two-port PoE switch.
With this, you can have a camera and a laptop to see and adjust the camera. By the way, it’s completely safe for the computer even though the computer is a non-PoE device.
