|120822 - 808 #17 Subjective Review - Opinion|
SUMMARY - Compared to all 808 versions the #17 offers these
firsts: A real 2MP image sensor. Real HD video at less than US$20.
No up-scaling of video or photos.
The #17 takes real 720p video and 2MP photos and produces good image quality. But, the video missing frame rate is high (bad).
The camera produces about 16 real frames per second and about 14 missing frame per second, the lens angle is somewhat narrow, and the shutter speed is somewhat slow. The #17 design seems to be an attempt to use 480p technology (an under powered SOC processor and MJPEG compression) with a 2MP 720p internal camera module and the design does not produce the best result. But for the price, it might be right for you. The #17 is sold on eBay by geeksea.
SAMPLE VIDEO AND PHOTO FILES
Go to the C17 folder in the vault.
● Priced at about US$16 it is the lowest priced 808 real 720p camera. Contrast that with the 720p #15 at about US$27 and the720p #16v2 at about US$42.
● The 2.0MP sensor produces real 1280x720 720p AVI MJPG video and 1600x1200 photos.
● The photo and video resolution is not up-scaled from the sensor resolution. Up-scaling is common on other 808 versions.
● Video has good automatic brightness and saturation.
● The photo and video aspect ratio is not distorted.
● The video file format is fully compliant and can be played and imported with any video software that plays AVI MJPEG.
● The photo Horizontal Field Of View (HFOV) is about 44 degrees which is wider than the video and slightly more wide than "normal".
● The missing frame rate from outdoor video is about 45% (terrible). That's about 16 real frames per second at about 120MB per minute with AVI MJPEG compression. Compare that with the #16v2 that produces 30 real frame per minute at about 50MB per minute with MOV H.264 compression.
● The video HFOV is 36 degrees, slightly more telephoto than "normal". Most users want a wider lens. As a comparison, the excellent #16v2 is available with multiple wide lenses from 52 to 90 degrees HFOV. For reference, a 35mm film camera "normal" lens is about 39 degrees HFOV.
● The 8000Hz sampled PCM audio quality is only fair to poor.
● The outdoor video contrast seems high.
● The video noise is sometimes high.
● The internal camera module is soldered so the user can't replace the camera module with a different lens angle.
● The internal battery is soldered so it is not consumer replaceable.
● The webcam mode crashes after a few seconds on both Windows XP-32 and 7-32.
● Date time stamp on video and photos can't be disabled.
