Abstract

The present invention relates to a ball cover, in particular to a ball cover on a high-speed ball, which is covered on the front-end equipment of security and protection system. A high-speed ball cover with thermostatic apparatus includes a shell which consists of an upper shell and a transparent cover and is equipped with semiconductor-refrigerating chips connected with direct-current power. The present invention adopts the advanced semiconductor refrigerating technique, and realizes auto warming and cooling in the high-speed ball to keep the temperature in the high-speed ball firm.

Description

technical field [0001] The invention relates to a dome cover, in particular to a dome cover which is covered on a high-speed dome, which is a front-end device of a security monitoring system. Background technique [0002] The high-speed ball is a front-end equipment for a security monitoring system that integrates optics, electronics, machinery, and information processing. It is composed of a camera, power transmission, and motion control device. Because it has multiple functions such as video camera, position control, orientation and lens preset, moving target detection, recognition and tracking, flame and smoke detection and alarm, it is more and more used in buildings, banks, airports, stations, customs Security monitoring occasions in , transportation, electric power, factories and mines, and places where people cannot be on duty. [0003] Since the working temperature of the high-speed dome camera is -5°C to 45°C, when the camera works outside this temperature range, t...
