菲律宾采购需求：救援设备、消防设备、警用及军用设备、气体检测仪、矿山安全设备、水上救援设备

I recently received a breathing detector model from your company, but I'm having some issues with the camera functionality. It doesn't seem to power on at all, and I'm not sure if I'm missing a step in the setup process. Could you provide guidance on how to turn on the camera? Additionally, I need assistance connecting the device to the software on my tablet. Any detailed instructions or troubleshooting tips you can share would be greatly appreciated. I look forward to your prompt response so I can get things up and running smoothly. Thanks!
