LPID vs. LBR - Heat Comparison
(low bitrate parking mode vs. low power impact detection parking mode)
By now we all know LPID uses less power than previous parking modes.
What I’ve been wanting to know is exactly how much less HEAT does it generate.
Driving down the road widows down, A/C blowing I’ve never has a dash cam overheat, and shut down.
But we’re all familiar reading about someone’s dash cam overheating, and shutting down in parking mode on a hot day.
And don’t use sunshades according to
@Mtz it will bake the camera to death.
For this heat comparison I set up two “identical” A329S 3CH cameras as close as I could, (what I mean by that);
A329S 3CH (Rear & IR Interior Fisheye) with HK6
A329TW 3CH (Telephoto & Waterproof Rear) with HK4
Both cameras have default settings except;
A329S = LPID
A329TW = LBR
Both cameras have 512GB Viofo Brand SD Cards.
Both powered by “identical” power supplies.
I’ve only got one Fluke Meter, so I’m using my UNI-T 210E Pro Amp Clamp as a “better than nothing”.
We can see LPID when powered by HK6 fluctuates between 39mA - 40mA.
LBR on the other hand is the neighborhood of 430mA.
(LBR) 12.6V x 430mA = 5.4 Watts
(LPID) 12.6V x 40mA = 0.5 Watts
I let the cameras acclimate to operating temperature by letting them bake for 1 hour in my garage.
Ambient temperature of my garage was 82℉ (28℃) 46% Humidity.
After 1 hour the hottest temperatures achieved measured with my TOPDON TC004 Thermal Imaging Camera;
144℉ (62℃) = LBR
94℉ (34℃) = LPID
It looks like LPID operates approximately 50℉ (28℃) degree cooler, (that sounds like a lot).
This should hopefully prevent overheating shutting downs on even the hottest days parked in direct sunlight.
Bravo Viofo!
Now if we could just get LPID power consumption down to Vueroid levels, and sub 1-Second wake up times that would be great. lol
Interesting side note for
@Nigel &
@rcg530
When the A329S (LPID) camera was “asleep” in LPID parking mode, I configured the A329TW (LBR), and when I powered it up it displayed on the LCD screen it paired to the HK6.
Even though the HK6 was physically plugged into the A329S, and the A329TW was plugged into the HK4.
I downloaded the last recorded file from the A329TW, and sure enough it displayed battery voltage in the text stamp at the bottom of recorded footage.
Is this a bug, or a feature, (see attached screenshot)?
Does this mean we can finally pair a single BTR200 Bluetooth Remote with multiple cameras simultaneously? lol
