Spotlight Cam Pro with Automatic Shut-off Timer

For some reason in the settings of Spotlight Cam Pro I am not able to adjust the Automatic Shut-off Timer as I am with my Floodlight Cams. After reading a few forum posts I have realised this is a common question that people have been asking for almost 3 years! Why is this very simple yet very importent feature not included in a "Pro" level product. The main reason I bought this camera was to partially replace my back door motion light not knowing it was severly lacking in features. Do better ring.
