When it comes to upgrading aging water metering infrastructure, most contractors face the same dilemma: replacing thousands of mechanical meters means digging up roads, breaking walls, laying kilometers of cables, and shutting down water supply for days. GUANGZHOU BASIC INTELLIGENCE TECHNOLOGY CO., LTD introduces the CWM 4G IoT Camera Remote Water Meter — a game-changing retrofit solution that eliminates all these headaches while delivering 100% accurate, traceable remote readings.
The Problem with Traditional Smart Meter Upgrades
Converting old communities to smart metering using wired M-BUS or NB-IoT water meters requires full meter replacement, complex wiring, and often civil construction. For property managers and water utilities, this translates into high material costs, lengthy construction periods, resident complaints, and extended water shutdowns. Worse still, many pulse-based smart meters suffer from cumulative reading errors over time, leading to billing disputes and customer dissatisfaction.
How CWM Solves It — Camera-Based, Not Pulse-Based
The CWM system takes a fundamentally different approach. Instead of replacing the existing mechanical meter, it attaches a compact 4G image recognition camera module directly onto the dial of DN15 or DN20 household meters. The module photographs the dial at scheduled intervals and transmits images wirelessly to the cloud via China Telecom's 4G network using UDP protocol. An AI algorithm then automatically recognizes the exact digits from the photo.
Because every reading comes from an actual photograph of the mechanical dial — not an accumulated pulse count — there is zero cumulative error. Every data point is backed by a stored original image, making billing disputes a thing of the past.

Where CWM Delivers the Most Value
The CWM 4G camera remote water meter excels in scenarios where wired infrastructure is absent or too costly to install: old residential compounds without pre-laid communication cables, rural scattered households, street-level retail shops, and small commercial buildings. Water operators gain instant remote visibility into consumption patterns, leak detection through abnormal usage alerts, and automated billing — all without a single pipe cut or cable trench.
