FourFaith IoT
Full-axis tilt monitoring supports customizable 0~180° open-cover alarm threshold with ±1° angular precision; alerts are uploaded instantly once the manhole cover moves abnormally.
Built-in float level sensor detects ponding up to 2m and automatically sends waterlogging alarms when exceeding limits; measuring range is customizable.
Collects underground ambient temperature synchronously and transmits device operating status in real time.
NB-IoT/4G dual-mode full-network communication, compliant with CoAP and LWM2M IoT standard protocols.
Dual-color LED indicator clearly shows device operating and network online status.
Supports scheduled status reporting & instant abnormal alarms, compatible with Four-Faith Water Cloud, OneNet, OceanConnect and other mainstream IoT platforms for data docking.
The F-IVD100 utilises DIC (Digital Image Correlation) combined with sub-pixel visual recognition algorithms, paired with passive targets to enable all-weather, long-range, multi-point two-dimensional displacement and vibration monitoring;The fully integrated, waterproof camera unit supports dual power supply via solar panels or mains electricity, with built-in high-capacity local storage and multi-link wireless transmission. A single device can simultaneously track thousands of monitoring points, eliminating the need to deploy large numbers of contact-type sensors and significantly reducing operational costs associated with on-site cabling, the procurement of monitoring equipment and regular manual inspections.
1. Highly integrated all-in-one design: battery, antenna, tilt sensor, liquid level sensor and temperature measuring modules are all built-in, only fixed installation is required on site.
2. IP68 fully sealed three-proof structure (waterproof, dustproof, corrosion-proof), pressure-resistant and shock-resistant, applicable to harsh underground environments with high humidity, ponding and drastic temperature difference.
3. Ultra-high response sensitivity: abnormal manhole displacement and underground ponding will be uploaded instantly with zero-delay early warning.
<4. Ultra-low power consumption control: sleep current ＜ 5μA, average overall power consumption ＜ 60μA; the built-in 8500mAh lithium battery achieves a service life longer than 5 years.
5. Flexibly adjustable alarm parameters: the opening trigger angle and waterlogging alarm water level can be configured remotely.
6. Universal IoT communication protocols, compatible with mainstream domestic and overseas IoT cloud platforms for convenient docking.
