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:
| Fonction de communication | 4G Cat.1 | NB-loT |
| Largeur de bande | 20MHz | 200KHz |
| Peak speed(UL/DL) | 10Mbps/5Mbps | 126kbps/158,5kbps |
| Amélioration de la couverture | +0 dB par rapport au GSM (similaire au GSM) | +20 dB par rapport au GSM (4 fois plus fort que le GSM) |
| Délai | <100ms, en temps réel | Deuxième niveau |
| Mobilité | Commutation en mode complet | Resélection de cellules |
| Voix | VOLTE/CSFB | Non pris en charge |
| Low power capability | Support DRX/eDRX/PSM | Support DRX/eDRX/PSM |
| Antenne RF | Dual/single antenna optional | Antenne unique |
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.
