Question 1: how high is the camera?

我在和客户沟通的时，很多时候都建议客户室内不低于2.5米，室外不低于3.5米，这些数字虽然简单但考虑到了室内的高度及镜头下压的角度，也考虑到了室外安装时照射的长度及防人为破坏的因素。

When I communicate with customers, I suggest that the customer is not less than 2.5 meters indoors and 3.5 meters outside. Although the figures are simple, these figures take into account the height of the room and the angle of the pressure of the lens.

问题二：支架安装有何建议？

Question two: what is the suggestion for the installation of the stents?

在装摄像机的时候都会有壁装和吊装两种选择，超市等室内环境吊装比较多，室外一般选择壁装。一般轻巧些的机器用普通支架即可，但是在使用较重的机器则建议客户使用承重较大的支架，摄像机的承重是我们必须考虑的，防止时间长了摄像头倾斜或者掉落的情况发生。

When installing cameras, there are two options: wall mounted and hoisting. There are more indoor environments such as supermarkets, and outdoor wall selection. The generally lightweight machine can be used with a common bracket, but the heavier machine is used to suggest that the client use a heavy bearing support. The load-bearing of the camera is what we have to consider to prevent the camera from slanting or falling for a long time.

问题三：室内、室外选择何种外观的机器？

Question three: what appearance machine does indoor and outdoor choose?

环境的不同选择的机器也应当不同。

The different choices of the environment should be different.

室内装修比较好的环境

A better environment for interior decoration

比如室内的咖啡店，精品店、酒店之类装修比较好的环境，出于美观理应考虑半球摄像机，这样显得比较美观。

For example, indoor coffee shops, boutiques, hotels and other decoration environment is better. For aesthetic reasons, hemispherical cameras should be considered, which is more beautiful.

室内环境特殊的场所

A special place in the indoor environment

然而一些粮油店、五金店、火锅店之类的环境虽也在室内，但得选择枪机，这样可有效防止粉尘、水汽、油烟等进入机器内部，影响机器的使用。

However, some of the food and oil stores, hardware stores, and hot pot shops, such as the environment is also indoors, but have to choose the gun, which can effectively prevent dust, water vapor, oil smoke and so on into the machine, and affect the use of machines.
