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:
| Communication function | 4G Cat.1 | NB-loT |
| Band bandwidth | 20MHz | 200KHz |
| Peak speed(UL/DL) | 10Mbps/5Mbps | 126kbps/158.5kbps |
| Coverage enhancement | +0 dB vs GSM(similar to GSM) | +20 dB vs GSM(4 times stronger than GSM) |
| Delay | <100ms,real-time | Second level |
| Mobility | Full mode switching | Cell reselection |
| Voice | VOLTE/CSFB | Not supported |
| Low power capability | Support DRX/eDRX/PSM | Support DRX/eDRX/PSM |
| RF antenna | Dual/single antenna optional | Single antenna |
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.
