Dark camera before IR comes on

[Saltster]

does anyone know why both of these cameras go totally dark for about 10 minutes before the IR comes on like in the right photo?

I resent it back to factory defaults but still dark.

Thanks

In the camera GUI config under conditions go to "illumiator" and set it to "low" with the shortest delay in the dropdown list.

 

[Saltster]

Would this be the delay?

Thanks

 

[sebastiantombs]

Yes, and move the sensitivity to low.

 

[Saltster]

Ok Great, now I will need to wait till tomarrow night.

Thanks

If you're using profiles remember to do the same for night.

Unfortunitly it still gets dark untill the IR kicks in.

It usedto look with the other videos.

That's quite a contrast you have there with the bright sky and the dark silhouette of your trees.
It's likely fooling the light sensor before switching to IR mode.
Do you also have IR mode set to come on based on light conditions?

Could it be the changing location of the sunset has caused this issue that wasn't there in the summer? And if they are cameras that have been there years, perhaps the direct sun at those angles has degraded the sensor over time.

It is best to set up a day profile and a night profile and use BI to switch between the two and then have the parameters dialed in for day and night.

You would set the Night Profile to be forced B/W instead of auto and then it will kick in earlier.

you could also ( if it has the feature) slow down the Day Mode manual shutter setting to a range of like .25-20 milleseconds. or even 30 milliseconds to capture that last bit of daytime light before it switches to Night Mode

 

[Flintstone61]

takes some trial and error

I wouldn't go any higher than 16.66ms for the exposure. Too much motion blur as it gets slower..

 

[Flintstone61]

but only for a couple minutes until the Reak darkness hits him maybe? just a transitional shutter to help that last dying light contrast until IR kicks in...

maybe, however in this photo the camera is also pointing at the same Banana plants
and the camera video was Ok with them there before?

RE: Do you also have IR mode set to come on based on light conditions?
No not sure how to go about that?

Thanks

how would I know if this is the case?
the camera is zoomed out, I tried zooming it in some, and it got lighter, just that then it is not videoing the driveway.

not sure how to set up profiles?

Thanks

It might not be an option.

Your screenshot from earlier shows the Day profile.
There will also be an option for Night.

Thanks, I have day and night set the same

Yeah if you set the day one you're probably setting for dawn not dusk.

If it's still not working try Wittaj's suggestion above of setting a day night schedule via BI. It's a proven method. From memory I believe most set the changeover 10 mins before sunset but probably Wittaj could confirm.

I am using an NVR not BI
and I'm not sure how to do this.

 

[wittaj]

You go into the camera GUI thru the NVR and after setting up the day and night profile, then go to Conditions>profile management>and select schedule and then draw out the day and night times.
