The invention discloses a video monitoring tester. The tester comprises a main control module, a display screen, an RS-485 interface module, an RS-45 interface module and a power module; the RS-485 interface module and the RS-45 interface module are respectively connected on the main control module, the display screen is connected to the main control module, and the power module is used for powersupply. The tester in the invention adopts a high-quality Android smart chip and a powerful operating system, thereby greatly improving the running speed of the whole machine; the whole machine adoptsa low-power PMU power supply design, thereby reducing the power consumption of the whole machine, greatly improving the stability of the product, saving the material cost brought by LDO separation components, and improving the time of endurance of batteries; the modular design of the product unit circuit enables the product function splicing speed faster and different models can be flexibly used,thereby facilitating problem analysis, hardware modification, upgrade and material control; and circuit PCB design layout specifications improve requirements for product reliability, production process, testing, maintenance and other aspects.
Description
Technical field [0001] The invention discloses a tester, in particular a video monitoring tester, which is applied to the field of civil security. Background technique [0002] Video surveillance tester is a mobile, portable, handheld, handheld system used in video surveillance testing to facilitate the installation and debugging of video surveillance testing. It is referred to as video surveillance tester, also known as surveillance tester. [0003] Previously, when there was no such equipment, the project would be very troublesome in the video surveillance installation. Because the video and control of the equipment could not be confirmed on the spot, it is necessary to contact the monitoring center personnel to check the effect at any time after installation, which is troublesome and wastes manpower and material resources. Some engineering companies even directly move the display and control equipment to the site for installation and debugging. With the development of technolog...
