The camera lens fogged up after being powered-on for only a short time; it obviously had moisture inside therefore I had to disassemble the unit and dry it out with a dehumidifier and once assembled sealing around the casing and SD card opening with silicone sealant. It's been good ever since... I received good support from Reolink in regard to disassembly and drying out the unit. Certainly not ideal but it saved time having to return it. Otherwise its a decent camera though I do get quite a few false triggers with changes in sunlight.
