4G automatic meter reading cameras are primarily used in water meter retrofit projects.In residential buildings,apartments,schools,and factories where mechanical water meters have already been installed,these cameras can be mounted without the need to replacethe existing water meters.This approach enables cost-effective and efficient transformation into AMR systems,effectively addressingthe various challenges associated with manual meter reading.

Comparison of 4G Cat.1 and NB-loT Technologies:
| Función de comunicación | 4G Cat. 1 | NB-loT |
| Ancho de banda | 20 MHz | 200 kHz |
| Peak speed(UL/DL) | 10 Mbps/5 Mbps | 126 kbps/158,5 kbps |
| Ampliación de la cobertura | +0 dB frente a GSM (similar a GSM) | +20 dB respecto al GSM (4 veces más potente que el GSM) |
| Retraso | <100 ms, en tiempo real | Segundo nivel |
| Movilidad | Cambio a modo completo | Nueva selección de celular |
| Voz | VOLTE/CSFB | No compatible |
| Low power capability | Support DRX/eDRX/PSM | Support DRX/eDRX/PSM |
| Antena de RF | Dual/single antenna optional | Antena única |
Summary:in terms of communication capability,Cat.1 has stronger ability and communication stability performance comparedto NB-loT based on mature LTE networks.In typical application scenarios,the power consumption of Cat.1 module products isclose to NB-loT.
