usb cam as dash cam - Android Q&A, Help & Troubleshooting

I've wired a Dell laptop webcam to work with my old Nexus 5. It works when using the 'usb camera' app though all the dashcam apps seem to only look for the front facing or back facing cameras.
Does anyone know if there is an app or something that is needed to have a dashcam app recognise the usb camera?

Connecting Vibrant to pc as usb webcam for skype calls, etc.

Hey everyone-
Before you say this just let me say that I've already tried the IP webcam app that acts a wireless webcam from your phone to pc. The app worked and I was able to see the stream from my phone in my browser, but I couldn't get it to display the stream in skype (although it did detect the webcam, the screen was just black. Anyway, I've been trying to figure out a way to connect my Vibrant to my PC via the usb cable and use it as a WIRED webcam, so that it would be picked up as an external webcam by windows. The only reason I prefer to go wired is because of the fact that I'm trying to get rid of any frame lag between when I speak/move and when the computer shows it, which I assume would be eliminated by a wired connection. If anyone has any ideas, let me know, thanks.

Any help? Thnx again
I definitely would love to know the answer to this also, although I admit I did not search google for results. I just ran across your post and now I'm curious.

it may work as video out, but not strictly as hardware like a regular video cam. Meaning you will need the special cables and a capture card on the computer......
When you say it might work as video out, what do you mean exactly? I realize it may not pick it up as a usb webcam automatically, but is there any way to trick into thinking it is a wired webcam or something similar with a piece of software or something?

Using Camera while Displaying HDMI output on Head Mounted Display

Hi everyone,
I am trying to connect a Head Mounted Display to my Galaxy SII and am able to connect it using a Micro USB to VGA MHL Adapter. I can look at the screen output ,gallery and other apps but I cannot use the Camera app.
I was wondering if there is ANY possible way (custom Rom,override some kernel file etc ) by which I can use the Camera app while showing the HDMI output ? .I was thinking of using 3rd Party Bluetooth cameras like Looxcie but it seems they dont provide any API . Another option would be to connect and external usb webcam through the adapter,But i am not sure whether I would be able to compile/find the appropriate drivers and whether i could access the camera from the Android SDK.
ANY pointers/tips/suggestions would be really appreciated
Thanks !
Try with 3rd party camera app, like lgCamera.

Android Phone like External Screen for Action Cam

Hi for some time, I'm looking for ideas for my solution. I have an android phone that do not currently use and I would use it as a screen for my action cam. Obviously it is already possible through the app and bt or wifi, but this way the battery runs out quickly.
Do you know any cable solution? My action cam (xiaomi yi) has both the USB output that that HDMI.
For Canon exists for the application DSLR Remote, maybe some of you know something for xiaomi.
Thank you all

Endoscope camera with M20P?

Hi all
I've tried a couple of endoscope cameras with the Mate 20 Pro (Micro USB to USB-C converter) but none of them seem to work. They don't seem to power the camera on at all.
Is this a general thing with the phone or have I just tried the wrong camera?
Cheers.
I have the same issue. The same camera works on my Pixel One, just not on this phone.
works on mate20 pro using an98 app

What camera are you using? Got a link to it?
Works on my Mate 20 pro too using the 'AN98' app .
Problem that people have appear to me to be two fold :
1) Some adapters to USB C do not work as should. Mu camera has USB micro B plug, and I bought two adapters, one original Huawei which worked both when on phone and on PC , the other adapter (a 'Goobay') worked fine when using on PC , but on the phone it couldn't even turn on camera light on. I don't know what the adapter problem is but it's there.
2) Most 'OTG' Endoscope camera software appear to work only with prior Android OS, and do not work with the one on my Huawei Mate 20 Pro , more of the Apps recognized that a camera were plugged in but had a black screen...
From what I have been able to understand then the software problem has to do with something called 'com.mainActivity.App' either in the software or on the phone..
When starting the AN98 App it has a black screen and gives a popup at start saying that the com.mainActivity.App may not work, then after that another popup asks that one 'allow the com.mainActivity.App to access the USB device' , and when that is granted then suddenly the AN98 App shows picture and works just fine - in fact it is the only app that my camera works with so far on the Huawei Mate 20 Pro.
The camera works just fine with other Apps on an older OS on Samsung Galaxy 5 !!!
I have an endoscope camera and also found the apps were the main issue. The camera works, leds light up but most apps just didn't show a picture. Try some till you get one that will work.

J3 usb camera support?

Hi just wondering has anyone got a usb camera to work with their j3? I've tried an "endoscope" usb camera and a regular usb webcam with an otg cable but neither work. With any app i've tried the camera is detected when I plug it in but either the app then crashes or just displays a blank screen. This is with stock firmware.

Old thread, but for others nowadays, my answer is that you must make sure the app supports the camera.
For years I've been using this app: https://play.google.com/store/apps/details?id=infinitegra.app.usbcamera&hl=sv
and it supports at least Logitech C270.
Recently I discovered that the app also supports a cheap videograbber usb stick, meaning I can get my old Olympus OM-D E-M5 connected to a big tablet and see the live screen there.
Haven't tried the app with an endoscope.
The app + C270 have worked on a Galaxy Tab 2 with stock firmware 4.1.2, but also some higher custom ROMs.
And a stock Galaxy Tab A (2016) running Oreo.
and just now I tested it on 2 devices, my stock J4+ with Pie and my stock J5 (2015) Marshmallow.
Edit:
I got curious and dug out an old long silvergray SuperEyes endoscope, only tried it on the J5, but above app supports it.
At the same time I found a small black cylindrical inspection camera with 2 meter cord. Above app supports that too
