Much appreciated Nicko!
Also is you know the SG9665GC can be powered by 12V and 5V USB power bank at the same time as well?
There are many questions / answers all around the forum regarding using Street Guardian SGZC12RC with external battery banks.
In this thread I have combined my tests to show different scenarios when using 5V external battery banks and 12 V power supply.
P.S. - all tests you see below were done over year ago.
Just finding this thread (September 7)
Thank you Niko for an informative presentation.
A question please
If one starts 5v motion detect recording with the capacitors are fully charged, how long will the capacitors hold their charge if 5v power remains uninterrupted?
perhaps this wording is better
How long will the capacitors hold their charge and be able to save a file when recording in 5v motion detect mode?
Best regards
Edward
Thank you NikoYou can see from 1st post 2nd video ( Part 2 ), - unit switches off immediately after 5V power "interrupted" and capacitors have enough charge to saves last file.
Thank you Joklin, and thank you Nikothe caps are only charged via 12v and are only depleted when saving a file, if you start on 12v and switch to 5v as some users do then it will save the file on shutdown no problem as they get charged up on 12v before any recording commences
Thank you Joklin, and thank you Niko
From the information the two of you have provided regarding the capacitors' function when saving and shutting down:
Can it then be said that by first charging the caps in 12v mode & then switching to a 5v aux battery and parking mode
- when I shut down the 5v power 8 hours (or more) later, the capacitors will have retained enough of a charge to save files upon shutdown?
Best
- should the 5V battery run too low on charge to support camera functions the capacitors will view that trickle down as a shut down and save files?

8 hours is no issue, 8 days maybe not
shutdown is a shutdown, if the caps were charged before you switched to 5v (ie you powered up from 12v before switching to 5v, recording does not commence until caps have sufficient charge for a shutdown) then the caps will still perform their function and save the file when the 5V supply gets low enough for the camera to power off

Here's a follow up question, If I may, Joklin
If the camera is started on 12v, operating in constant record mode, what happens when switching to 5V?
Will the camera stay in constant record mode, switch to motion detect mode or...........?
