Deployed FOMO model is not working correctly in esp32 cam

Hi guys.
I deployed my fomo object detection model in esp32 camera but it does not detect objects. it only outputs
“Predictions (DSP: 8 ms., Classification: 577 ms., Anomaly: 0 ms.): No objects found”
continuously. but it works when testing the model with my laptop camera or from my phone.
it would be really helpful if you guys give any recommendations
Thank you!
