How to remove humidity from the camera dome

Condensation or fog that appears inside the camera dome on the ROV can reduce image clarity and overall camera performance. Condensation inside the camera dome is usually caused by trapped moisture inside the ROV, or in some cases, by a small leak in the dome area.

Explanation

The most likely cause for condensation inside the dome is trapped humidity inside the drone. Moisture can enter the system during battery replacement, especially if the battery or the surrounding environment is wet. Humidity may also accumulate if ports are left open during storage or the drone is used in a high-humidity environment. In rare cases, a small leakage in the dome seal may allow moisture to enter over time.

Solution

• Inspect the battery compartment
  Open the battery tube and check for any water ingress or condensation signs.
   
• Dry the system
  To help remove trapped humidity, place the drone with the battery cap removed for an extend in a dry environment for a longer period. 
   
• Ventilate the guest ports
  Remove the guest port connectors or blind plugs to allow additional ventilation. If necessary, keep them off for an extended period.

Prevention

Always ensure that all ports are tightly closed when storing the drone to avoid humidity issues. Humidity can enter the system when changing the battery in a humid environment or if the battery is wet.
