If USB camera functionality is limited or unavailable, several alternatives can fulfill similar needs. Choosing the right approach depends on your specific requirements.

Network Cameras (IP Cameras): These cameras connect directly to a network (Wi-Fi or Ethernet) and can be accessed remotely via an app or web browser. They offer flexibility and can often be used without any direct USB connection to the Android device.
Built-in Camera: Utilizing the device’s built-in camera and its associated apps is the most straightforward solution. Modern smartphones and tablets typically have excellent built-in cameras capable of high-quality video and image capture.
Wireless Camera Systems: Some manufacturers offer wireless camera systems that communicate with an Android device via Wi-Fi or Bluetooth. These systems often include their own dedicated apps and offer a user-friendly experience.
Cloud-Based Solutions: Services like Google Photos or Dropbox can be used to store and access photos and videos taken with other cameras, offering a convenient way to share and manage your visual content.

Scenario: The Factory Floor Fiasco and the Workaround

Imagine a bustling factory floor. Quality control inspectors need to inspect products for defects, using a USB camera connected to Android tablets. Suddenly, several tablets, primarily older models, are experiencing intermittent camera disconnections and poor image quality. The cause? Insufficient power delivery from the tablet’s USB port, coupled with the high power demands of the USB cameras used.

The factory cannot stop operations.

The Limitation: Inadequate power delivery from the older Android tablets to the USB cameras. This causes the cameras to disconnect randomly, and the image quality deteriorates, making inspections unreliable.
The Workaround:
- Powered USB Hub: The factory implements powered USB hubs. These hubs provide their own power source, ensuring the USB cameras receive sufficient power, bypassing the limitations of the tablet’s USB ports. This allows the cameras to function consistently and at optimal performance.
- Camera Optimization: The inspection software is configured to use lower resolutions and frame rates when the cameras are connected to the older tablets. This reduces the power consumption of the cameras without severely impacting the inspection process.
- Tablet Upgrade: A phased upgrade of the older tablets is planned, prioritizing newer models with improved USB power delivery capabilities. This long-term solution eliminates the need for workarounds.
