The dAV-Cr-4K from mk-Messtechnik is an EMC shielded camera designed for visual and acoustic monitoring of test objects during EMC tests. It has a 1/1.8“4K CMOS image sensor with a resolution of 3840 x 2160 p that enables high-quality DUT evaluation and an opening angle of 58.5 deg. It consists of an in-built mono microphone and NiMH battery with 10 cells. This shielded camera has about 18x optical (12x digital) zoom and a duplex optical fiber for video/remote. It requires a shielded power supply of 110 - 130 V and measures 135 x 80 x 80 mm including connectors and switches, and is cased in an aluminum enclosure of up to 800 g. This EMC camera is ideally suited for monitoring EMI and EMC tests, due to the optical signal transmission and the shielded housing.
