Answers.Text: These external triggers are usually called intervalometers, can often find them on amazon for around $30, you need the right connecting cable for your camera. Not every camera has an external trigger input, and you need to make sure that yours will interpret trigger input as "start recording", not "take a photograph". You then need to measure the exact time your camera can record in one go, and set the intervalometer to trigger at an interval of that time plus a second or two.

Comments.Text: Such record limits on still cams can also be related to legislation. For example, many DSLR cams stop at 29:59, because hardware that video records 30 minutes or more is taxed differently.

Comments.Text: Nevermind.  I misread the question.  Didn't realize you were talking about photo cameras.  AVCHD is a sony/ panasonic *video* camera thing.  Other video cameras have similar formats, but as others have posted here, photo camera video file limitations are often artificially imposed for regulatory reasons.

  Depending on the camera model used, one could expand the recording time a 4GB file can take up by reducing the recording quality (compression, bit rate, resolution...) of your video.
  
  With SOME cameras, you might be able to use an SDHC card forcibly formatted to a file system that does not have a 4G file size limit, eg exFAT or NTFS. If you can make it work, test THOROUGHLY.
  
  Be aware that certain cameras also have a hard coded 30 minute video limit, which is there for reasons all unrelated to file size: In some markets, video cameras are taxed higher than still cameras, and the definition of a video camera in the relevant tax codes is continuous video recording capability beyond 30 minutes.
