The first step
拿出支架，准备好工具和零件：涨塞、螺丝、改锥、小锤、电钻等必要工具；按事先确定的安装位置，检查好涨塞和自攻螺丝的大小型号，试一试支架螺丝和摄像机底座的螺口是否合适，预埋的管线接口是否处理好，测试电缆是否畅通，就绪后进入安装程序。
Take out the bracket and prepare tools and parts: expansion plug, screw, screwdriver, hammer, electric drill and other necessary tools; according to the installation position determined in advance, check the size and model of expansion plug and self tapping screw, try to see whether the screw mouth of bracket screw and camera base is appropriate, whether the embedded pipeline interface is handled well, whether the test cable is unblocked, and enter the installation procedure after being ready.
第二步
Step two
按照事先确定的摄像机镜头型号和规格，装上镜头（红外一体式摄像机不需安装镜头），注意不要用手碰镜头和CCD，确认固定牢固后，接通电源，连通主机或现场使用监视器、小型电视机等调整好光圈焦距。
Install the lens according to the model and specification of the camera lens determined in advance (the infrared integrated camera does not need to install the lens), pay attention not to touch the lens and CCD by hand. After confirming that they are firmly fixed, turn on the power supply, connect to the host or use the monitor and small TV on site to adjust the focal length of the diaphragm.
