Technical documentation for the PGST WiFi/4G Kit reveals a Tuya-based ODM chassis featuring dual-path communication via 2.4GHz Wi-Fi and a legacy 4G GSM/LTE cellular slot. The system utilizes an unencrypted 433MHz protocol for its peripheral sensors, which provides an open-field range of 100m, though real-world penetration is limited by physical barriers. The central hub includes a 3.7V lithium backup battery, providing 4 to 6 hours of operation during grid failure.
Performance metrics for the PIR motion sensors indicate a reliance on standard infrared triggers without advanced thermal discrimination, which may lead to higher false-alarm rates. The internal siren output is rated between 85-90dB. The hardware is cloud-dependent for mobile application alerts and lacks support for modern encryption standards such as Matter or Zigbee 3.0. A separate SIM card is required to enable the 4G failover functionality.
The Ring Alarm 5-Piece Wireless Smart Home Security Kit provides a more secure, encrypted alternative with integrated professional monitoring and Z-Wave signal stability.
This hardware is indexed within the smart security kits category, focusing on multi-path communication for residential monitoring.
