The GT680W is a compact dashboard digital camera that is offered under the chinese Shadow Tec / Sheezeus logo. Like some of the cameras primarily based on the famous Novatek NT96650 processor and the Aptina AR0330 CMOS sensor, video excellent at some point of the day is superb and night time high-quality is right as properly. We would love to thank our member niko who provided the overview for this digicam on our discussion board.
It data 1080p at 30f/s with an average bit fee of about 15,000kpbs. The digital camera is quite compact and springs with a 2.7″ display screen. There are 2 models to be had, 1 with GPS and 1 without GPS. This camera is likewise sold as the HD-190 in Taiwan.
The digital camera is pretty small measuring 80x50x35mm. The original version has a few silver coloured components (lens, part of the casing) but Sheezeus has launched a more discreet, all black version as proven beneath. We endorse the black version as it’s far much less important.
The GT680W is presently one of the smallest cameras with the Novatek NT96650 processor and the Aptina AR0330 CMOS sensor. As may be visible from the following photograph, it’s far smaller than a preferred credit score card and simply barely larger than the Mini-0801.
extensive Dynamic range
at the same time as the Novatek NT96650 Processor helps wide Dynamic variety, the CMOS sensor used, the Aptina AR0330, has a dynamic variety of 72.four dB (see datasheet). for this reason from a pure technical attitude, this digicam isn’t supplying true extensive Dynamic variety.
This digicam has these days been launched and there may be constrained facts on reliability. but some problems had been raised:
GPS Does now not Lock
The early versions of this digicam had a GPS module that might no longer lock. This apparently was an problem for foreign places buyers since the GPS module worked in China. Later variations of this digital camera are the use of an progressed GPS module that has resolved this hassle. word that you must use firmware V2.4G or better with the GPS enabled camera.
underneath are interior photos of the GPS modules for the GT680W on the left and the GT550WS on the right. both are excessive exceptional modules.
Waving historical past Noise
The GT680W has a “waving” high pitch noise on the historical past, that is normal for most NT96650 based sprint cameras. there’s no regarded decision for this hassle.

Low capability Battery
The GT680W is geared up with a low potential one hundred ten mAh internal battery. This is probably because of the compact nature of the digicam. The low ability battery has enough energy to close of files and save the date. but, as the battery gets older, it may now not have enough strength to complete these capabilities.
