Test condition terminology
The following test-condition terminology was used for the power-dissipation measurements.
| Test Specification | Idle State | Work State | Maximum Power Consumption |
|---|---|---|---|
| Video Stream | 1 (1080p) | 1 (1080p) | 1 (1080p) |
| Relay (J8003/J8004) | Off | On | On |
| Ethernet | IP ping | IP ping | IP ping |
| Speaker Volume | 0 (0%) | Default | 5 (100%) |
| Video Call | No | Yes | Yes |
| +5VD_WG | On, Load=10R | On, Load=10R | On, Load=10R |
| RFID Card Read | No | No | Yes |
| Touch TP Key | No | No | Yes |
| LED Backlight | 0 (0%) | Default | Full (100%) |
| Heating | No | No | Yes |
| Remark | Video stream 1 (1080p) is the highest resolution. | – | Speaker volume 5 includes video call sound, RFID card read sound, and touch TP key sound. |
