Why motion sensors cannot be disabled and only activated during an Alarm?

All alarm company motion sensors seem to work the same, an led eluminates when a motion is detected at all times. The problem I have is the Ring Motion detector has a very bright led that gives off a strobe effect. Walk around in a dark room and it's like a flash going off. It also fills up the log that a motion was detected. There might be times or reasons to detect motion while you are home but if I'm home I do not need to have my motions logged and the annoying flash. I ordered an extra motion detector, before installing the system, to install in my bedroom because the window design makes it difficult to install a contact sensor. Now I cannot use it. You can deactivate alerts, why not motion detects that causes the flash. Can tape be placed over the Led?
