GENERAL

Warnings

• When not in use, always store the ORUS-L series in its designated storage case. Replace the desiccant pack as needed to prevent lens fogging caused by high humidity. If fogging occurs, it will typically clear after the device has been powered on for a short period. → Recommended storage conditions: humidity < 40% and temperature 20 ± 5°C.

• Avoid exposing the infrared camera lens to high-energy sources such as direct sunlight, lava, or laser beams. Exposure may cause irreversible damage to the infrared sensor.

• Ensure that the observed target temperature remains below 800°C (1472°F), or 1600°C (2912°F when an infrared density filter is installed). Exceeding these limits may result in permanent sensor failure.

• Refrain from placing the product in direct sunlight, poorly ventilated environments, or near heat sources (e.g., heaters), as this may affect performance and durability.

• Avoid frequent power cycling. After powering down, allow at least 30 seconds before restarting to prevent potential damage and reduced product lifespan.

• Prevent liquid ingress into the product. Ensure the surface and all ports of the gimbal are completely dry prior to installation.

• Avoid direct contact with the lens surface. Take care to prevent scratches from sharp or abrasive objects, as these may degrade image quality.

• Use only a soft, dry, and clean cloth for lens cleaning. Refrain from using alkaline or corrosive cleaning agents.

• Handle the product with care. Mechanical shock, dropping, or impact may result in malfunction.

• Note that the IP55 protection rating (per IEC 60529) is validated under controlled laboratory conditions and may degrade over time with use and environmental exposure.

• Be aware that the use of an infrared density filter may affect thermal image quality.

Product Profile

Orus-L is a specialized payload developed by Gremsy, designed with a spherical aerodynamic shape and rated IP55 for water and dust resistance. Built to endure harsh environments, including dust, humidity, and light rain, Orus-L remains stable even at speeds up to 100 km/h. It's an ideal choice for high-speed UAVs and demanding missions.

Storage Conditions

Recommended Storage Environmental Conditions

When not in use, GREMSY payloads shall be stored under the following conditions:

• Ambient Temperature: 18–25°C

• Relative Humidity: 30 – 45 %RH

These conditions are recommended to ensure long-term reliability of electronic components, gimbal motors, camera sensors, and mechanical assemblies.

Recommendation: Use a dry cabinet to keep temperature and humidity stable and well-controlled.

Storage Requirements Based on Non-Operating Duration

Non-Operating Duration	Storage Requirement
≤ 12 hours	Should be stored under the recommended storage conditions.
> 12 hours	Must be stored under the recommended storage conditions.
Long-term storage / standby	Always store under the recommended storage conditions.

Warning: If the device is not maintained under the recommended storage conditions

• 12-72 hours: condensation on the sensor lens may occur.

• 72 hours: there is a high risk of moisture-related damage.

Important Notes

In high-humidity environments (80–90% RH), dry cabinet storage may be required sooner than the time frames listed above.

Failure to follow these storage conditions may result in:

1. PCB oxidation and corrosion

2. Reduced gimbal motor lifespan

3. Electrical connector and camera sensor malfunction
