Fix the focusing bug in IR mode
The functions of customizing the sound content have been added to the voice broadcast and alarm sounds
VC40.45.1.3.0-251218 is a cloud-based version, and the following points need attention after the upgrade.
1）Default settings need to be restored after the upgrade.
2）If an SD card is inserted in the IPC, it needs to be formatted after the upgrade; otherwise, video recording will not function properly.
3）IPC-PTZ-E4XIR8MP-MD ：If you are using red and blue warning lights, do not upgrade this cloud Firmware. This is because the logic of the red and blue warning lights has been changed, and they will become ineffective after the upgrade. This is not a bug, but a compatibility issue arising from the connection between the cloud-enabled IPC and the non-cloud NVR.
