Technology and Components Fixed network cameras are digital imaging devices that capture video and encode it into network-friendly formats (commonly H.264, H.265, or MJPEG) for transmission over Ethernet or Wi‑Fi. Key hardware components include an image sensor (CMOS), lens (various focal lengths and fixed or varifocal options), onboard processor for encoding and basic analytics, network interface, and often an infrared (IR) illuminator for low-light operation. Many units support Power over Ethernet (PoE), allowing power and data over a single cable, simplifying installation.

These are novel. One housing contains three independent fixed lenses (e.g., 2.8mm + 8mm + 25mm). This replaces three separate networkcamera installations. You cover "overview, zoom, and detail" without a single moving motor.
