监控安装教程：
Monitoring installation tutorial:
第一步
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.
第三步
Step three
拿出支架、涨塞、螺丝、改锥、小锤、电钻等工具，按照事先确定的位置，装好支架。检查牢固后，将摄像机按照约定的方向装上；
Take out the bracket, plug, screw, screwdriver, hammer, electric drill and other tools, and install the bracket according to the position determined in advance. After checking firmly, install the camera according to the agreed direction;
第四步
Step 4
如果需要安装护罩，在第二步后，直接从这里开始安装护罩。1、打开护罩上盖板和后挡板；2、抽出固定金属片，将摄像机固定好；3、将电源适配器装入护罩内；4、复位上盖板和后挡板，理顺电缆，固定好，装到支架上。
If the shield needs to be installed, install the shield directly from here after the second step. 1. Open the upper cover and rear baffle of the shield; 2. Pull out the fixed metal sheet to fix the camera; 3. Install the power adapter into the shield; 4. Reset the upper cover and rear baffle, straighten out the cable, fix it and install it on the bracket.
第五步
Step five
把焊接好的视频电缆BNC插头插入视频电缆的插座内，确认固定牢固。
Insert the BNC plug of the video cable into the socket of the video cable and confirm that it is firmly fixed.
第六步
Step 6
将电源适配器的电源输出插头插入监控摄像机的电源插口，并确认牢固度。
Insert the power output plug of the power adapter into the power socket of the monitoring camera, and confirm the firmness.
第七步
Step 7
把电缆的另一头接入控制主机或监视器(电视机)，确保牢固。
Connect the other end of the cable to the control host or monitor (TV) to ensure it is secure.
第八步
Step 8
接通监控主机和摄像机电源，通过监视器调整摄像机角度到预定范围。
Power on the monitoring host and the camera, and adjust the camera angle to a predetermined range through the monitor.
监控摄像头的调试：
Debugging of monitoring camera:
安装镜头时，首先去掉清监控摄像头及镜头的保护盖，然后将镜头轻轻旋入摄像机的镜头接口并使之到位。手动光圈则应将摄像机的电子快门开关置于ON，并在应用现场最为明亮(环境光照度最大)时，将镜头光圈尽可能开大并仍使图像为最佳(不能使图像过于发白而过载)，镜头即调整完毕。装好防护罩并上好支架即可。由于光圈较大，景深范围相对较小，对焦距时应尽可能照顾到整个监视现场的清晰度：
When installing the lens, first remove the protective cover of the monitoring camera and lens, and then gently screw the lens into the lens interface of the camera and make it in place. For manual aperture, the electronic shutter switch of the camera should be set to on, and when the application site is the brightest (with the maximum ambient illumination), the lens aperture should be opened as much as possible and the image is still the best (the image cannot be too white and overloaded), and the lens adjustment is completed. Install the protective cover and mount the bracket. As the aperture is large and the depth of field is relatively small, the clarity of the whole monitoring site should be considered as far as possible when focusing the focal length
当现场照度降低时，电子快门将自动调整为慢速，配合较大的光圈，仍可使图像满意。调整过程中，若不注意在光线明亮时将镜头的光圈尽可能开大，而是关得比较小，则监控摄像机的电子快门会自动调在低速上，因此仍可以在监视器上形成较好的图像；但当光线变暗时，由于镜头的光圈比较小，而电子快门也已经处于最慢(1/50s)了，此时的成像就可能是昏暗一片了。
When the illumination of the scene decreases, the electronic shutter will automatically adjust to slow speed, and the image can still be satisfied with a larger aperture. In the adjustment process, if you do not pay attention to open the aperture of the lens as large as possible when the light is bright, but close it relatively small, the electronic shutter of the monitoring camera will automatically adjust to the low speed, so it can still form a good image on the monitor; but when the light is dark, because the aperture of the mirror head is relatively small, and the electronic shutter is already at the slowest speed (1 / 50s), the imaging can be done at this time It could be dark.
