Maybe you could ask the customer service for the app for it, it is easy and quick.

Maybe you need to carefully read the instruction.Usually camera automatically recorded by default, but there are exceptions.Then choose the record button,if it work,it will have the video.Hope it is useful to you!

Do you try a new camera, or check the BNC?Maybe there is something wrong with the camera.If new camera could work ,all will be OK.If not,just ask for maintenance staff.

Specific camera has its own dedicated NVR and program, you should know when buying, in order to ensure the normal use of the latter.

First ,other cameras could work once they are on the wall? Second, how you check it, if make a video? These are important for the others to help you.Or it is difficult to say what's wrong with the camera.

Please check all interfaces are connected correctly.If all is right,maybe you could ask for the customer service.
