Deep Dive Teardown of the TP-LINK Wireless Visual Cat Eye TL-DB635A Smart Doorbell
The TP-LINK Wireless Visual Cat Eye #TL-DB635A is a smart video home doorbell. Using WiFi connectivity, it is capable of streaming audio and video. The producer used a 180-degree field of view through the design of the lens that tilts down. Several manufactures share design wins for the TP-LINK Wireless Visual Cat Eye. The device is based on SigmaStar’scamera SoC #SSC335D. The same producer is responsible for the WiFiconnection via SoC #SSW114BS. Cmsemicon delivered microcontroller, while AWINIC supplied audio amplifier. The 3A Battery Charger Texas Instruments #SBQ25303J is responsible for managing the energy in the battery, supported by Battery Fuel Gauge and Battery Protection. To implement smart AI detection and notification, the following were used: 3 MP CMOS Image Sensor and Camera SoC with Memory by SigmaStar#SSC335D. Image realization is additionally supported by PIR Motion Sensor NiceraSensor#RE200xxx and Ambient Light Sensor. The camera and Home Base do not contain additional Power Management.
