Authentication Failed Axis M1011

Java is odd, so it actually still uses the USBCamera class for IP cameras, but thanks anyways!

Try building the Example project,

In Eclipse it can be found in

File-> New Project> Example Robot Project -> Vision -> Axis Camera Sample

In order for it to work you must follow the setup instructions here

Best of luck!

That's weird. I could have sworn we used the AxisCamera class to get to it last year.

I would advise against using the Axis netcam. It has a nasty habit of deciding to stop working for without warning for nebulous reasons. If you can use a USB camera instead, do so.

That hasn't been my experience with them. I use about 28 of the Axis M1011 and M1013 for security cameras and I track their uptime with Nagios checking them every 60 seconds. Most of them were at 100% uptime for 2015 if you remove instances where I had the network down for maintenance reasons. I might have 4-5 instances in a year where our weekly drop off the grid to generator power and back again mucks with the camera just right to keep it from coming back on.

In short: If you keep them powered up they keep trucking.

I have seen one of them flake out after 3 years of service though. Some days it would work and some not.

The issues I have had have all been their IP configuration somehow getting screwed up. We lost our camera halfway through last year due to this, with no discernible cause. We were not able to get it working again, despite the aid of several CSA's and multiple hours of dedicated effort.

I didn't know that existed, but I found it (when I looked at the examples which I hadn't done before...).

When I set it up I got another error:

ERROR Unhandled exception: VisionException [com.ni.vision.VisionException: imaqError: -1233721680: Unknown error] at [com.ni.vision.NIVision._Priv_ReadJPEGString_C(Native Method), com.ni.vision.NIVision.Priv_ReadJPEGString_C(NIVision.java:29329), edu.wpi.first.wpilibj.vision.AxisCamera.getImage(AxisCamera.java:113), org.usfirst.frc.team1124.robot.dashboard.DashboardConnection.initCamera(DashboardConnection.java:28), org.usfirst.frc.team1124.robot.Robot.robotInit(Robot.java:70), edu.wpi.first.wpilibj.IterativeRobot.startCompetition(IterativeRobot.java:72), edu.wpi.first.wpilibj.RobotBase.main(RobotBase.java:241)]

But at this point we are just going to use the USB camera.

Note to anyone who has this error in the future:

The axis camera only works when the robot is enabled, so only execute camera.getImage() when the robot is enabled.
