ATC9K Review Follow-Up

Battery Life

Yesterday, after getting my Class 4 16Gb microSD card in the mail, I finally had a chance to test the battery life of the camera. My result is about 2 hours 50 minutes continuously shooting HD/30 video with GPS unit activated. During this time, my position was mostly stationary with clear view of the sky, so it’s possible that the battery would have been drained faster if GPS signal was interrupted from time to time. I periodically pressed the video button to bring the screen to life and see if it’s still recording (I’ve set the privacy mode to be my default – possibly another factor, though given how efficient LEDs are, I doubt it)

Memory Use

During the test, the camera wrote three video files – 2 files 3.8 Gb each and 1 file 2.7 Gb with the larger files being approximately 1 hour 04 minutes long  and the smaller file being approximately 40 minutes long.

Motorcycle Noise Issue

As I mentioned in the main review, I experienced an issue with a high-pitch noise appearing during the acceleration when mounted on the handlebar using the provided handlebar mount. Trying to alleviate the problem, I’ve replaced the rubber fitting that sits between the mount and the handlebar with special sorbothane, hoping that the vibrations would be absorbed. Unfortunately, the sorbothane fitting did not help – it “delays” the appearance of the noise, but does not eliminate it – so, the quest for mounting camera on the motorcycle continues.
