Dismantling comparison of cottage and high-end camera: spying on camera

Comparison test of disassembling spy camera high-end camera

From boring text conversations to video chats, people ’s online connections are no longer so “embarrassing”. In the past, the network was not well developed. It was very difficult to think about smooth video. Users can conduct video chats smoothly even under WiFi, so the reasons that affect video quality are now narrowed down to video chat tools.

From a separate camera to a product with voice function, it can be said that the current camera is enough to make users dizzy from appearance to performance, and users do not lie in the difference of tens of dollars when buying, just like a clear picture with Good call quality. Today, PChome computer home is around two high-end products on the market for disassembly testing, from the internal materials to see the differences between products.

High-end camera real shot comparison test

This time we chose the famous domestic manufacturer Blue Demon T900 and a brand's high-end products. The official price of the Blue Demon T900 is 285 yuan, while the price of another high-end product is as high as 380 yuan. From the price point of view The two products do not belong to the same grade. This test is divided into two parts. First, the actual shooting is carried out, distinguishing from the picture effect, and then the product is compared to the product, and the comparison is based on the interpretation of the materials.

Real shot test——

The first comparison chart mainly observes the realistic effect of the banner. You can see that the performance of the blue demon T900 is very good, without obvious distortion, and the performance of the other product is a bit "unworthy". The overall picture gives People feel black.

In the second picture, we can see the difference from the notebook display. The performance of the blue demon T900 is still very good.

Contrast test of internal materials for camera disassembly

The disassembling process of the camera product is not troublesome. By analyzing the design scheme of the camera, it can be seen that the positioning of a product is performance.

What surprised me is that the blue demon T900 chose the sunplus solution, the main control chip is sunplus spca2000a, there is very little information about this chip, it should be a special chip for sunplus. Unlike the previous Zhongxingwei and Songhan solutions, sunplus chips are generally used in MP4, digital photo frame and other products. The other high-end product uses the mainstream SONiX Songhan SN9C250 solution. The main control chip is not too bad in performance. It can be used with CMOS image sensors from VGA to UXGA (2 million pixels).

Camera disassembly comparison test overview

Whether chaos is the actual shooting or the design plan, the blue demon T900 is superior, but the price is nearly 100 yuan lower than the so-called high-end products of a brand. It seems that even large brand manufacturers need us to think twice. purchase.

A common problem of ordinary cameras is that there will be a white piece when running under strong light, and the appearance of the blue demon T900 Deluxe version of the fast shadow technology completely solves the disadvantage that the camera cannot be used outdoors. Seeing indoor lights and sunlight entering through the window behind the banner did not affect the shooting results. Here I would like to remind users to measure the effect of using them outdoors when buying, and do not blindly believe in big brands.

The blue demon T900 deluxe version uses the sunplus solution that only appears in MP4, digital photo frames and other products, and the sunplus SPCA2000a chip should be directly supplied by a separate manufacturer. From the product quotation, the price of this chip should not be too much High, but the shooting effect is significantly better than the mainstream Songhan, Zhongxingwei and other solutions, with higher cost performance, users can also find the materials of the product main control chip on the Internet in advance during the purchase process, doing this in the heart A few will avoid being confused by big brands or profiteers to the utmost.
