In case your Ring camera showing purple light, do not panic, as it is related to the camera's infrared (IR) night vision feature and thus very common. The purple or pinkish light is a result of the IR filter inside the camera not being able to switch properly between day and night modes. This may occur, among others, due to the lighting environment, software, and/or hardware functionalities.
The IR filter can get stuck due to a sudden light change. Try to very carefully cover the camera lens with your hand for five seconds, and then see if the color has changed after you remove it.
The sensor may get confused by either too much or too little light. Shift the camera’s place so that it is not directly sunlit or facing a reflective surface.
Unplug your Ring camera, let it stay unplugged for around thirty seconds, and then plug it back. This is quite often useful in resetting the internal filter and hence erasing the purple tint.
Take advantage of the Ring application to see if there are any firmware updates available. A version that is not up to date may be the reason behind the image display malfunctions.
Should the problem persist, you can perform a reset Ring camera by pressing and holding the setup button for fifteen seconds approximately. Go through the connection with the Ring app again.
If the problem still exists, the IR filter of the camera may be broken, and it is advisable to get in touch with Ring Support.
The purple light of the Ring camera is usually a little night vision fault. Normally, a power cycling or resetting restores the color to its usual, and this way your Ring camera is perfect day and night.
