Purple hue at night time on some cameras

[EJN]

See attached photo. This started in December. I haven't opened a support case and wanted to check here first. We have 102 cameras and it's happening in about 10-15 of them.

MV22 and MV72

Thanks for any insight.

Perhaps its a hidden Jimi Hendrix mode?

Jokes aside, I haven't seen this on any of the cameras I have access to. But it sounds like a hardware malfunction. I'd just reach out to Support and request a quick t-shoot and then RMA the units.

Not happening for me, what firmware version are you running? 

[EJN]

I'm on 4.9.

Try toggling High dynamic range (Under Settings > Video settings) off and on

[EJN]

I'll try that toggle tonight. Good tip to test.

HDR toggle off/on fixed the issue. I'll confirm tomorrow once the cameras go through a 24 hour day/night cycle.

[BlakeRichardson]

Good to know its fixed and not a hardware issue. I'm guessing that the lighting in that area is messing with the camera sensor if HDR is enabled.

Thanks for letting us know the issue is resolved. 

[EJN]

Let me clarify that HDR was off. What fixed it was toggling it on/off. It's like the sensor was stuck and the toggle did a reset to off. I'm curious to see if it holds on the next transition to day time and night time. I will report back on Saturday morning.

@EJN  ah thats not so good.

I have had this happen, in the past, on maybe two occasions, where this fix has worked (and maybe on different cameras, I think) - it certainly hasn't been something I've needed to apply regularly.  If you get regular recurrences, I would raise a case with the Support team and mention what you've had and what you've done.
