Description
1. Product Overview
The DT-T73 is a high-performance combination tester built for CCTV professionals. It integrates IP camera (IPC) testing, analog / HD coaxial testing (CVI/AHD/TVI), Ethernet testing, PoE testing, TDR cable testing, PTZ camera testing, audio testing, and a 4½-digit digital multimeter in a compact, portable device.
Compatible with ONVIF, RTSP, and RTP as well as the HD-CVI 3.0, AHD 3.0, and HD-TVI 3.0 standards, it decodes H.264/H.265 streams and supports 4K resolution at 30 fps. With a 4-inch TFT display and a replaceable lithium-polymer battery, it is well suited to field work — simplifying fault diagnosis and significantly improving technician efficiency.
