Why use laptop cameras?

• They are cheap

Silicon Motion's second-generation NVMe SSD controllers have all but taken over the consumer NVMe SSD market. Drives like the HP EX920 and ADATA SX8200 currently offer great performance at prices. Cameras: Olympus PEN F, Olympus OM-D E-M1, Panasonic GX8, Panasonic GH4. One Inch – 9 x 12mm. These sensors have become very popular in recent years, especially in premium compact cameras. They offer a sensor which is much larger than a conventional compact camera, but still small enough to fit in pocket friendly devices.

If you have a broken laptop, you are exceedingly likely to have a camera you can reuse.

• They are small

Unlike the usual webcams, the laptop cameras are very small and easy to hide.

• They are easy to connect

You just need to connect two USB wires, ground and power (preferrably, 3.3V).

• Usually good Linux support

The majority of laptop cameras play well with Linux and will work with the default tools (i.e. ffmpeg, mjpg-streamer, gstreamer and v4l-utils)

• Good hardware

What are the problems with laptop cameras?

• Comparably low quality

While the cameras might advertise 1.3M sensor, the quality of the actual image. One thing - the image quality is directly , it's directly corellated to the age of the laptop you're sourcing the camera from - i.e. if the laptop was made in the last 5 or so years, the camera is going to be much better than, say, a camera from a 10-year-old laptop.

• Bad autofocus, no software-controlled manual focus

Compared to i.e. Logitech cameras (that I use a lot where the budget allows), there's a lot to strive for when it comes to laptop cameras and focusing them.

That's not to say that re-focuseable laptop cameras exist - I own one like that, it came from a high-end laptop, but it's definitely not common. And still, compared to cheap webcams from China, there is barely any difference, so if your choice is between picking a cheap camera from eBay or disassembling a laptop, it's better to disassemble a laptop =)

• Lack of hardware encoding

Many cameras actually don't stream a raw image over USB and instead compress the image into something more lightweight - i.e. MJPG (widely available) or H264 (usually available in more expensive cameras) If you're streaming the image over the Internet, the hardware encoding of the camera will allow you to offload your CPU significantly (especially if you're streaming from a device with a weak or already busy CPU). Laptop cameras don't typically have MJPG hardware encoding, unfortunately, that's reserved for high-end webcams, i.e. Logitech higher-end models.

How do you reuse a laptop camera?

Any easier way to solder wires to the connector?

Can you use laptop camera microphones?

Yes, you can reuse them. I won't be covering this, but the idea is simple - these microphones usually use PDM, in a configuration like this:

However, giving any further advice will require knowing more about the PDM communications standard, and unfortunately I haven't worked with it yet.
