Hello,
Do you know of any camera that starts recording (to a micro-/SD/SDHC/SDXC/SDUC/... card) right after a power supply is connected to it, and stops recording right after that power supply is disconnected from it?
If it has an internal battery (for instance, to keep track of time, while disconnected from the external power supply), that is OK, but it should not impede the camera to start recording right after the external power supply is connected to it, as I said.
An external circuitry -with a very low standby current- will detect proximity, and will apply power to the camera only while needed, thus keeping the average power consumption very low. The external circuitry will not press any button on the camera. It will close or open an electronic switch (MOSFET), to apply/cut power to the camera. Therefore, cameras that need a button being pressed to start recording, and cameras that need a button being pressed to be powered on and start recording, are not useful.
Thank you.
