An external phone camera is an accessory that connects to a smartphone to provide imaging capabilities beyond the built-in camera. These devices expand the utility of phones for professional and creative applications.
What Can an External Phone Camera Do?
An external phone camera can provide thermal imaging, endoscopic inspection, microscopic magnification, night vision, 360-degree capture, or high-zoom photography—capabilities that built-in phone cameras don't offer.
How They Connect
External phone cameras connect via USB-C, Lightning port, or WiFi. Wired connections offer zero latency and no battery, while WiFi models provide flexible placement and wireless freedom.
