Technical documentation identifies this system as a cloud-dependent security appliance built on the Tuya Smart ecosystem. The internal circuitry utilizes either a TYWE3S or WBR3 wireless module for 2.4GHz Wi-Fi uplink. Performance data confirms a dual-radio operational mode, employing 433.92MHz RF for communication with peripheral sensors, which operates without rolling code encryption. The 120dB peak siren output is generated via a single-tone piezo element housed within the main chassis.
Physical dimensions and power metrics include a USB-C input requirement of 5V 1A and a 3.7V Li-ion battery providing a 2-4 hour operational window during mains failure. Sensor power requirements are met by non-rechargeable lithium coin cells (CR2032/CR2450).
Material analysis indicates that the 433MHz band utilized for sensor telemetry is subject to signal congestion in dense urban RF environments. Technical specifications suggest bridging these units to local MQTT controllers to mitigate cloud-based latency and potential de-authentication events.
Given its reliance on unencrypted RF signaling, the YBJ 21-Piece Kit may be considered as a comparative alternative due to its higher sensor density within the same protocol ecosystem. This device is categorized under the pre-packaged DIY alarm kits standard for consumer-grade security hardware.
