The package you want is motion. https://motion-project.github.io/ Take a look at this thread: https://pimylifeup.com/raspberry-pi-webcam-server/

I'm running the latest motion under raspbian-stretch and I am having a problem I can't resolve. I have a number of IOT devices monitoring various events which send email alerts. I'm developing another monitor and for testing purposes I replace the email script named in on_movie_start with one that b...

I'm running WebIOPi 0.7.1 on raspian-stretch. I've got a problem I can't resolve. Command "sudo /etc/init.d/webiopi stop" does not stop the process. The log says it's stopping, the PID file is deleted and everything appears to be OK, except the process lives on, healthy as can be. I can't find any e...

Your carrier may have an email SMS gateway. Most US carriers do. Verizon, for instance, uses the address "[email protected].com", where "number" is the 10 digit telephone number. I use this format to send SMS alert messages from various RPi IOT devices such as leak detectors and motion detectors. There ...

Do you have both the AP and client set to the same channel? They should be. I had some trouble with my Android phone connecting to the AP when in dual mode, but I had full functionality with my Windows PC.

barry914

Yes it does. Make sure you have this set correctly:

Code: Select all

# Restrict stream connections to localhost only (default: on)
stream_localhost off

Nothing like that has ever happened to me.

I guess this was just another case of "when all else fails, read the instruction book. Boots up, configured. works. Thank you very much for the quick and correct info.

I hope this isn't a duplicate. I'm using an image with motion that I have been running with motion on a B3 and I can SSH into that. I also have the WLAN properly configured. I did edit the hostname and hosts files before I tried booting the W. It does not show up on my router even when I connect it ...

I'm using 4.4.38-v7+. I'm booting in headless mode, trying to SSH into the device. It does not show up on my router either.

Yesterday I picked up a Pi Zero W from Microcenter. I burned a Raspian image onto an 8GB SD card, plugged it in but it won't boot - activity light is off. I just got back with a replacement, and this is not booting either. I checked the image in a Pi 3, and it works, and I tried a known working card...

I'm not sure why it's necessary to turn power save on when shutting down the interface. I have no apparent issue with just turning it off.

barry914

I'm not sure this is related, but I have no problem connecting to the AP from my laptop, but my Android phone won't stay connected. It gets an IP, stays connected for a bit and then disconnects. I get an error message that says it received an unknown SSID. I think when the phone gets the router's SS...

I'm running stock motion with a pi camera without any problems. The only change I needed to make to the system is to load the bcm2835-v4l2 driver at startup. Is there any reason to use the motion-mmal version?

barry914

OK, the issue of handling the connection failure is resolved, but there's still one open issue. Why doesn't Raspbian's slow boot option work? Any ideas? The timing and error messages are the same regardless of that configuration setting.

barry914

What you want or do not want to do is irrelevant. You have exactly 2 options: 1) learn how to deal with the init and start the process after network is up. It does not have to be a daemon, there is "oneshot" type for that. 2) handle the exception in python itself, eg: if exception is risen wait for...

I had an application that would send out a gmail message on failure, but it recently quit working as gmail increased their security. This could be your problem. I solved it by switching to a text message using curl. You can also change your gmail security settings to a lower level and see if that f...

Python has that capability. In my original post I alluded to maybe this belonging in the Beginner's forum, which kind of reflects my understanding of handling exceptions in Python.

barry914

One minor problem. It doesn't work. I checked and rechecked that I have enabled slow boot but I get the same error and the same remedy fixes it. Now I'm totally confused. For reference, this is running on a Pi Zero with an Edimax dongle.

Indeed there is! Thanks you for your help.

but when run at boot from crontab it fails. It fails because network is not up yet. Make your script start via systemd service and make that service depend on networking.[/quote Well, yes, I know why it's failing. Other than creating a daemon process, is there a simple way to check the network stat...

I have a python script that polls a sensor and generates an email when the sensor becomes active. Works great, except for one detail. I recently added a function to send an email when the script starts. When run from the command line, everything works as expected, but when run at boot from crontab i...

And here's another: http://naelshiab.com/tutorial-send-email-python/

I use these methods in my IOT monitors for various alarm conditions, like leak detection, access monitoring, etc.
