No — I couldn't find any smart camera rated to operate at 75°C or above. Filtering the Smart Cameras group for a maximum operating temperature of at least 75°C returned no matching products.
The closest option I verified is the EverFocus PHX-N2120-F500 (Jetson Orin Nano/NX based), rated for -20°C to 70°C — 5°C below your requirement. Its operating temperature range also comes with a condition: it requires airflow . everfocus... +1everfocus.com ↗“thermal.max_operating_temp_c=70 °C”everfocus.com ↗“Requires airflow”
To be clear: this is a near match, not a product meeting your 75°C requirement. Across the Smart Cameras group, the maximum operating temperatures present are 25, 40, 45, 50, 55, 60, 65, and 70°C — none reach 75°C. If 75°C+ is a hard requirement, you may want to discuss it with a Physical AI representative or the individual vendors, since catalog-rated figures may not reflect every available configuration.
