Yoosee Wi-Fi cameras based on Goke GK7102 SoC

Relying on low-cost strategy, the shipment of Yoosee Wi-Fi cameras steadily grows. Yoosee is approaching the goal to be one of popular brands for home security. According to the latest statistics disclosed by Gwelltimes, the monthly shipment of Yoosee camera modules has already reached 200,000 pieces.  The most majority of Yoosee camera modules employ low-end SoCs from Grain Media and Hisilicon. However, some users may find out that your camera may use a different processor – Goke GK7102.

We previously wrote an article to introduce the Goke GK7101 and GK7102 HD video processors, Goke’s SoCs have been widely used in cost-effective professional IP cameras, now their SoCs are gradually being used in other camera applications since the company intends to expand the market share. We wish to share you more information about the Goke SoC, however, the company doesn't publish the processor's datasheet, therefore we only can have limited information from their Chinese website. In this article, we will be intent on introducing you the low-end Wi-Fi camera solution that based on GK7102 + SC1135 and GK7102 + H42 chipset. 

1.0MP/720P Wi-Fi Cube Camera GK7102 + H42

Open your camera, you will see its PCB board, Goke G7102 is used as the core processor, while you will see a Wi-Fi module which is MT7601 from MediaTek. If you removing the lens and the IR-CUT module, you will see its CMOS image sensor. The CMOS image sensor is H42, which is a 1/4” progressive scan CMOS image sensor offers 1.0 megapixel resolution, it’s designed for low-cost HD video applications, it’s able to deliver [email protected] video. 

1.3MP/960P GK7102 + SC1135

SC1135 is a 1/3" progressive scan CMOS image sensor from SmartSens, SmartSens is backed by the government funding, the company mainly produces CMOS image sensors that can be used for many HD video applications. The company now has the capability to produce up to 5-megapixel CMOS image sensors.

2.0MP/1080P GK7101 + SC2135

SC2135 is a 2-megapixel CMOS image sensor for Full HD cameras. Compare to the rivals, SmartSens CMOS image sensors have the comparative advantages on perspective of cost. Therefore, many security camera manufacturers are delighted to use the SmartSens to replace other brands including Sony, OmniVision, ON Semiconductor, as this can maintain the competitiveness.
