Due to the increasing requirements for the definition of images and videos, the installation of detection instruments is required to be more and more complicated. At present, in the installation and maintenance of a security monitoring system, numerous tools need to be carried, such as a multimeter used for monitoring circuits, a network tester for network diagnostic test, an optical fiber conversion head, an NVR, a display connected with the NVR, various connection cables (VAG, HDMI, power supply of different specifications), and the like. The current machines on video installation detection on the market only aim at analog vision monitoring test, network H.264 and MPEG4 camera test tools, and the high-definition test tool can only support up to 1200 ten thousand pixels of cameras, and most of the machines can only test 1080P (200 ten thousand pixels) and up to 4k (4096 x 2160 or 2840 x 2160) network cameras.
