The practical signal
Condensation sometimes appears only during temperature changes. A camera can then look normal again, while a damaged seal or cable entry still allows moisture to enter.
advice
Check the camera for moisture and condensation
Moisture can temporarily obscure the image and eventually damage components; the route through which water enters is therefore more important than just the visible result.
The control sequence
Check enclosure, mounting surface, cable entry, wires and visible cracks. Note when the complaint occurs and whether there are also dropout, streaks or night vision problems.
What is smart to do
Repair the cause of indoor moisture intrusion with a suitable mounting or replacement solution. Do not drill additional openings or fill seals by luck with random putty.
When it is completed
Check the image after rain and temperature difference and test recording. Record the performed sealing or replacement for future assessment.
Frequently asked questions
Does the condensation disappear on its own enough?
Not if the cause continues to exist or if image and reliability are affected.
Can a moisture problem make a camera offline?
Yes, moisture can also affect connections or electronics in addition to lens haze.
