$3xx Flycam test




Worth HKD $350. Very tiny lipo,charging current is <100ma.>

The ram is made by SAMSUNG

Test photos. focus and colour not bad!
Real test data:
640 x 480 still capture
Video is only 352x 288 , 15 fps, around 10M/ min. video capture. Therefore 2G should be able to capture 240 mins. video.

Video Data:
bitrate 1945 kps, Ankarec H.263 codec, 914 kps
Audio PCM 128k, 8000KHz, 16 bit
Youtube can accept this raw format!
For Windows movie maker2, you need some software to transform (not re-encode, but transform the container such that WMM can read)

low light condition is satisfactory.
Sound quality is bad. De-syn !
Lipo charging has safety IC chips to protect over discharge and charging (G2NS powered by 8205T)
MCU is Anyka AK3224M. An old product with video and sound compressiosn.
The stock USB cable sucks. Took me 3 hours to find out the charging problem is due to the USB cable. Charging requires the cam to be switched "ON". Weird!
Orange LED flash on charging and lit continuously on full charging.

Non-stop video till fully charge battery shutdown: 90mins, captured 650M video
Full charging takes 60 mins.

Fully charge can takes ~ 1:30 mins video
With higher capacity lipo/ connection to 5V source) It can take video continously till the internal ram full, with clips of 1:30 hr each. Ext. SD ram not tested yet as the battery seems to be limiting factor.
The internal ram is SAMSUNG ram.
