While this camera is as described there are some issues to be aware of when used the usa

First off there is no way to switch this camera to 60hz so there will be no 704x480 d1 option and you will be limited to 25fps maximum

The lack of d1 means that some north american nvrs may have issue with the 704x576 option you can select 640x480 and your nvr should recognize it

This camera also has 3 steam channels without the option to enable or disable the third channel which poses another problem with some nvrs defaulting to the third channel for the sub stream instead of the standard second sub stream channel the issue with this is that the third stream is limited to 1fps maximum

Posted by a reviewer on Amazon

The only way to resolve the issue is to set up a custom protocol using rtsp and defining the main and sub rtsp streams or change the video encoding to h265 which in some cases the nvr will not recognize and ignore the third channel allowing proper use of the 2nd sub channel

Compared to other hikvision turret style cameras the image is similar however the saturation is a little less and the sharpness power is very strong 65 on this camera is equal to 100 on some of my hikvision turrets

If you understand the limitations of this asian import with multi language firmware and can work with it then you will have yourself a great value of a camera

If you need something that will integrate easily without having to change settings in the camera menus then you may want to buy a usa version instead
