Review of Aiptek HSHD Hybrid Camcorder with External Microphone Jack

October 15th, 2008 . by alitton

We have been working on a project that needs a low cost camcorder with an emphasis on audio quality over video quality. Part of this search has been looking for a less than $500 camcorder and preferably less than $300 unit with an external microphone jack.  This is due to the horrible internal microphones and sound quality on most consumer camcorders. You have only to listen to 99.9% of all Youtube videos to know what I mean. The manufacturers have dropped this feature on most everything below $500-660 dollares and it is getting rarer on sub $1000 models.

Aiptek has had several hybrid camcorder/camera models it markets overseas in the sub $300 range that have external microphone jacks, but only recently introduced a model here with that feature.  The model in question is the Model HSHD. The specifications in short are:

  • 1280 x 720 H.264 Video @60fps
  • 1280 x 720 H.264 Video @30fps
  • (Also 848 x 480 WVGA H.264 @ 60fps)
  • 2GB Built-in Storage
  • MOV Video Format
  • 32GB SDHC Card Slot Expansion
  • External Microphone Jack
  • MP3 Player
  • 2x Digital Zoom w/ Fixed Focus & Macro Setting
  • HDTV Component Output
  • Up to 3 Mega Pixel Digital Camera (actually fixed at 3M)
  • 2.4" Swivel-Reversible LCD
  • Night Shot
  • Easy Charging via AC or USB

I purchased this camera from Circuit City almost entirely on the basis of the external microphone jack feature to see if it would really improve the audio. If you are considering it for this feature I would keep looking. The external microphone performance was a big disappointment as described below.

Playing with QR Codes

March 23rd, 2008 . by alitton

qrcode
I'm sure this is something you will be seeing more and more of. It is called a QR Code™, QR standing for Quick Response and is something being pioneered by our cellphone centric friends in Japan.

This 2D barcode format was originally developed by Japanese automotive component manufacturer DENSO for tracking automotive parts. Since then is has become an increasingly popular method of encoding URLs, addresses, phone numbers, contact information and other information for use by camera enabled cellphones.

The cellphone user snaps a picture of the barcode and software in the camera translates it into text and can hyperlink to the encoded URL instantly. It is being used by advertisers to directly link to their sites as well as venues such as galleries, museums and zoos to hyperlink displays to more detailed multi-media information than can be contained on a sign or placard.
