We've just added Battery Powered Spy Cameras! These hidden cameras do not need any power cords, no cables, not even a separate recording device. Long life battery provides up to a year of stand-by so you aren't changing or charging batteries every day.
Motion or Thermally activated, you also won't have to watch hours of video that don't have anything on there. These high-end spy cams only capture the video when there is somethign to record.
