There are several lights on most of the camera and they should be similar although refer to your Status LED
Solid Blue- Being charge
Flashing Blue -Ready for set
Red and Blue- Updating
Flashing red- Alarm triggered
Solid red Live stream or recording
So could it be that you are triggering an event that is recording you triggering the event or are you streaming the camera when you are finding the red light on the camera.
You should get a notification if it is triggered by you and no notification for a streaming event.
I have found through random testing that the camera do have a pretty decent side view. I know the one cameraI I have can trigger a notification close to being parallel to the camera. So almost a full 170 something out of 180 degree field of detection)
Depending on the sensitivity of the motion detection, I have seen detection as far as 200 ft as well. A lot of time this is due to all motion with a high sensitivity. This could cause detection due to the wind is blowing a plant or etc.
The other question would be is it daylight or near darkness as the IR light may coming on if it is thinking that it saw something.
Other than that you can check with the service department for further assistance as well.
