# Working Advice

Check the environment that you want to inspect, paying particular attention to obstacles or hazardous areas.

Bend the camera cable (1) so that the camera head can be easily introduced into the environment to be inspected. Carefully introduce the camera cable.

Adjust the brightness of the camera illumination light (5) so that the image is easily recognisable. When photographing highly reflective objects, for example, you can achieve better results in lower light or using black and white contrast setting.

If objects to be inspected look blurred, then reduce or increase the distance between camera head (4) and object.
