Recording indicators

A system, comprising:

• a camera comprising:
• an image sensor;
• a lens barrel comprising one or more refractive lenses, wherein the lens barrel is configured to refract light received from an object field to form an image at an image plane at a surface of the image sensor;
• and
• a recording indicator comprising one or more light sources, wherein the recording indicator is activated when the camera is in recording mode and deactivated when the camera is not in recording mode;
• and
• memory for storing video captured by the camera when the camera is in recording mode;
• wherein the system is configured to capture and store video frames during integration periods when the camera is in recording mode;
• and
• wherein the recording indicator is configured to emit pulses of visible light from an area aligned with an opening of the lens barrel towards the object field during non-integration periods between the integration periods when the camera is in recording mode, wherein through the opening the lens barrel receives the light from the object field to form the image at the image plane at the surface of the image sensor.
