IR Full HD 1080 Watch




This Spy watch performs as expected with this price. Video captured has size of 1920x1080, frame rate of "30" and data bit rate of 8Mbps. Performance is less than satisfactory but this is expected for this price.
 Yet it is fun to open it up and have a look of the design. Interestingly, there is a large 8Mb ram as buffer. MicroSD is changeble and is class4 . ATTO test of stock microSD card is very fast, indeed. The unsatifactory performance is likely caused bt the slow encoding chip  STK2365 , capturing in 15fps motion JPEG. I cannot find any information from alldatasheet. As far as I know , there is only 3 chip factories that is capable of making FullHD 30fps low cost encoding chip . Default setting will capture continuous video clips of each 20mins size 1.3GB .  If configuration is allowed to capture at 720p with 30 frames, then this is a very good gadget.
Performance in no light situation is good with help of IR, which gives some spotted reflection underneath the glass.
