Capture crisp, clear images with select Nikon DSLR cameras using this Insignia™ NS-WSCN wireless control that remotely activates the shutter to help eliminate vibration caused by manual shutter depression.
Does exactly what it is intended for. The mode on the camera the shutter controller uses does turn off if not used for a minute or so, but thats my camera and may differ for other models. Sufficient knowledge of your camera is helpful in setting up the controller since the device itself does not come with much instruction.
