Aggregated specification data lists the NGTeco 9-Piece Kit as a Tuya-based white-label system utilizing 433MHz RF for sensor communication and 2.4GHz Wi-Fi for its hub-to-cloud connection. Technical documentation confirms the absence of local API access and 5GHz Wi-Fi support. The internal 3.7V lithium battery is rated for 2 to 4 hours of backup time. Performance metrics for the integrated siren indicate a peak output of 120dB, though internal mounting within the hub chassis can result in significant acoustic muffling.
Material analysis suggests the contact sensors use non-standard battery sizes and adhesive mounts that may require replacement for long-term stability in high-traffic areas. The 433MHz frequency used for the nine peripherals is unencrypted, lacking protection against RF jamming. Logic processing is entirely cloud-dependent, requiring a continuous handshake with external servers for push notifications and system status updates.
- Sensor Count: 9 Peripherals
- Frequency: 433MHz Unencrypted
- Network: 2.4GHz Wi-Fi
- Protocol: Tuya Cloud
The YoLink LoRa Smart Door Sensor Starter Kit is a technically superior alternative for users who need a local-execution fallback and significantly more robust signal encryption.
This hardware bundle is cataloged within the smart security kits repository as a cloud-locked monitoring solution.
