Webcam

[beatsal]

Just wonder why I need a special PI webcam to get videos/pix. Why will a normal webcam not work, I use a webcam for Skype, so it should work?

[KLL]

you have a old USB cam?
connect and run
lsusb
find it?
now can use for test:
sudo apt-get install qv4l2

i did not need to select or adjust anything, it just worked.

now to use it as ( motion detect ) security ( IP ) webcam:
sudo apt-get install motion
sudo nano /etc/motion/motion.conf
like: (deamon on) ( video codec mp4 ) (target_dir /run/shm) ( stream_localhost off )
LAN PC browser:
RPI_IP:8081

Some webcam cameras work, some don't. What model do you have?

a short search here at forum shows that your usb cam Cubeternet WebCam should work,
but one poster had not found how to record audio from it.

still not getting pic from webcam like you showed in your post.

[KLL]

your list is incomplete, can not see anything
- - it's the second time you post parts of a install
- - not showing what you install / ( what the command was )
- - and again not put it in Code tags
+ + + i show you exactly how it ( the install ) should look on terminal, so compare it and only post it if different from mine.

after update upgrade,
did you again install qv4l2?
was it successful?
can you start that program? [from menu/ video ] and did you see the qv4l2 window?
if it finds the usb cam, did you select the [capture] to start the viewing video window?

[beatsal]

Confused, not sure i.e. cannot understand your post. Nice if you can list the commands that I should enter to get a pic. Am a beginner, so completely stuck. Thanks

[KLL]

sudo apt-get update
sudo apt-get -y upgrade
sudo apt-get install -y qv4l2
[menu][sound +video][qt v4l2 test utility][/capture/start capturing/]

[beatsal]

Thanks KLL; works great!

[beatsal]

My webcam works fine with my PI from remote but now am thinking of replacing it with a webcam that can pan/tilt/zoom from remote, any suggestions?

[beatsal]

KLL, Please respond!

[KLL]

sorry, i never play with that,
sure there are PTZ cams for USB, but mostly IP cams ( so you would not need a RPI at all ) used as security CCTVs.

[beatsal]

Thanks KLL.
My webcam works fine from remote thanks to you. I monitor my home since I am away for a week at a time. Only problems is that at night the whole place is dark so camera does not help. I need to turn on a 120 V light remotely from my PI so the camera can see. Not sure how i.e. what HW and SW?

[KLL]

for a security CCTV at night should use one with IR led light,
a HD storage recorder would help the police,
anyhow a timed lamp ( after power fail the on off timer units without electronic clock and backup battery work wrong, better have just a Photoresistor unit)
and a outdoor CCTV ( with a visible led ) already keeps unwellcome visitors away.

look for options:
+ + IP cam || RPI + USB cam || RPI + NOIR CAM
+ + WIFI || ethernet cable signal
+ + PTZ
+ + night vision + IR led
+ + (semi) outdoor ( under shadow and direct rain protected )
- - cheap outdoor housing not have the glas for IR application
+ + recorder ( min 1TB HD )
+ + mobile app / remote connection

hmm, if you think twice, does PTZ and recording ( if PTZ not operated ) together give some useful results?

[lerner]

My turn to ask.....

I have a HQ USB camea and thought I would try this.

I don't have the "camera control" tab as shown on yours KLL.

(See attached)

And just while I am at it: Is this a thing I could use for real time video watching of the camera - rather than setting up motion?

Not that I am being super paranoid, but more just out of interest.

Thanks.

[KLL]

-a- I don't have the "camera control" tab
-b- Is this a thing I could use for real time video watching of the camera

@lerner
-a-
well, i see that tab, with a old 12US$ usb cam ( OKER 88 )
it has only one option: Exposure, Auto [ Aperture Priority Mode || Manual ]
whatever that means.
-b-
and yes, QV4L2 can be used to see the cam live video
on desktop / VNC desktop ( see above 2 VNC screen shots )
or what you think it is for? why you install it?

did you try [capture][start capturing] == [ green > ]
and does it work? you see the video window or not?
__________________________________________________________________
i tried the motion not for the "motion capture",
only to test the web server function.
what actually makes a ( RPI + USB CAM ) == IP CAM

-c-
and when you find out how to use the QV4L2 photo snapshot function tell us.

[beatsal]

KLL, any specific models of camera you suggest that would work with PI?

[KLL]

sorry, i never play with that

but if you reduce your expectations from
PTZ
down to
PT digitalZ
can get a reasonable prize like here
but that is a indoor IP CAM and has nothing to do with RPI.

[beatsal]

Thanks KLL.
I will connnect a 120 V light to a module on the PI and will turn it from remote. Not sure how to do it and what module to use. Has to be a module actuated from the PI Output. Kindly help.

[beatsal]

Hi KLL,

TRYING TO USE the PI camera v2, works fine locally but not with VNC i.e. remotely. Any help appreciated - thanks

[DirkS]

Hi KLL,

TRYING TO USE the PI camera v2, works fine locally but not with VNC i.e. remotely. Any help appreciated - thanks

Pi camera preview / video doesn't use the framebuffer so VNC will not show it.
RealVNC has an experimental setting which can do it, but I'm not sure about the speed / quality.

[KLL]

some graphic stream not show in VNC unless enabled, like here:
https://raspberrypi.stackexchange.com/a/66142

sorry i have currently no camera setup installed, can not help you more.

Hi KLL,

TRYING TO USE the PI camera v2, works fine locally but not with VNC i.e. remotely. Any help appreciated - thanks

Which VNC? If you're not using RealVNC server on the RPi and RealVNC client on the remote machine then you have a cat (or snowball) in hell's chance of getting it working.
