Open camera feed from from object-detector-python example

[asimeonovMLPS]

Hello everyone, we have an AXIS Q1615 Mk III Network Camera and we are getting an error when running one of the examples from object-detector-python. Here are the details of how I run the example.

Values of environment variables: export ARCH=armv7hf export CHIP=tpu

export APP_NAME=acap4-object-detector-python export MODEL_NAME=acap-dl-models

export DEVICE_IP=my-Ip-here export DOCKER_PORT=2375

Command: docker --host tcp://$DEVICE_IP:$DOCKER_PORT compose --env-file ./config/env.$ARCH.$CHIP up

There seems to be a problem with opening the camera feed through openCV, when calling cap.read() I get (False, None).

Any help will be highly appreciated.

Thanks in advance.

Hi @asimeonovMLPS
Can you verify that you have the latest firmware installed (11.5)

[asimeonovMLPS]

Hi @Corallo, thanks for the quick reply. Now I checked and the current version for AXIS OS is 10.12.104.

It is expected the example not to work anymore with firmware version lower than 11.1 Update the firmware and it should work fine

Thanks @Corallo, I'll try it right away.

Thanks @Corallo, I have now upgraded to version 11.5 and it works great.
