Mobius Maxi Support Thread

[kandrey89]

Here are my results.
Summary:

• Issues: Standby (STDBY) current is too high, firmware needs to be fixed because the sensor is running while it shouldn't be. Power consumption depends on which mode the camera is in, if the mode is set for 1080p60 then your standby current will be much higher than 480p240.
• Video Quality (Normal vs Extremely Fine) causes an increase by 0.05W at most, thus does not generate extra heat
• 1080p60 has the highest power consumption at 2.0W
• 480p240 has the lowest power consumption at 1.1W
• WiFi ON mode refers to running the image sensor but not saving video to disk, streaming video to device consumes 0.3-0.4W (480p vs 1080p60)
• Saving video to disk consumes 0.3-0.6W (480p vs 1080p60)
• Highest power consumption mode is 1080p60 with WiFi streaming at 2.7W
• G-Sensor and microphone do not consume much power <0.05W
• Megapixels per second and FPS do not linearly correlate to power consumption as seen from 4K24 vs 1080p60 and 1080p60 vs 720p120 FPS measurements.
• Current draw is not constant, depending on mode, current could be constant 0.22A or it could be 0.2A to 0.5A based on what the processor is doing.
• Temperature rating corresponds to power consumption. 2-3W will burn, 1.4-2W will be very hot, 1.2-1.4W is hot, 1.1-1.2W is very warm, <1.1W it is warm.

Megapixels per second and FPS do not linearly correlate to power consumption as seen from 4K24 vs 1080p60 and 1080p60 vs 720p120 FPS measurements.

2.7k (and the interpolated 4k) consume less power than 1080p and below since they are saved in mjpg format rather than h264.

AliExpress has one of they're sales starting in 2 days. I'm definitely considering upgrading the current 64GB cards that's I'm using.

Couldn't resist.

Even if you've vetted the available options, still not the best place to buy memory cards.

Does it affect any other frames, or just the first one?

I don't get it, you zoomed in, or does it show an overlapped block in your image?

Is there a list of lenses that are hi-res 3-5MP with different focal lengths and FoV numbers that fit Maxi? Thinking of building out a set of different cameras with different FoVs/zooms.

I don't think anyone has compiled a list. I suggest looking at these threads:

Mobius Telephoto Dashcam

After reading a number of DCT threads recently (@Dashmellow , @dirkzelf , @kamkar1 ) on trying new lenses with the Mobius camera, I decided to have a go myself. My primary aim is to find good fast telephoto lenses which allow the Mobius to operate as a second camera alongside a traditional wide...

Mobius 5MP Varifocal Zoom 6-22mm ƒ/1.6

I just took delivery of a new lens to play with on the Mobius, a 5MP Varifocal 6-22mm ƒ/1.6 zoom in a 1/2.5" sensor format purchased from Treeye on AliExpress. I understand that @TonyM purchased one of these as well. Here is a new thread where we can discuss our results. Even though I had a...

Looking forward to trying these pair out.

Will complete full speed test via PC later too, to clarify these are the real deal (to which I do not doubt)

Use https://www.softpedia.com/get/System/System-Miscellaneous/H2testw.shtml software to test that it actually stores ~256GB by writing unique files and then verifying that all of the information is stored. If it's a fake card it'll store 8-64GB of whatever was last written, and overwrite any data written before that.

 

[L22eew]

Little update. All checked out fine, as expected.

 

[kandrey89]

Samsung 512GB Evo microSD card was:
H2testw v1.4:
Reading speed: 79.6 MByte/s
Writing speed: 51.6 MByte/s

 

[TonyM]

My recent H2testw results for comparison:
Samsung 64GB Evo+ U3: 59MByte/s write ; 73MByte/s read
Viofo 64GB MLC U3: 62MByte/s write ; 72MByte/s read

Any decent U3 card should support write speeds far in excess of the maximum data rate on the Mobius Maxi

 

[TonyM]

I can't remember if this has been mentioned this before. There is a water-resistant case available for the Maxi, which might appeal to motorcycle dashcam users?

Good day to all.

Has anyone here in the thread, attempted to use the Maxi - on motion detect, hooked up to a external power bank?

I'm only asking because i'm going to be leaving my vehicle in a Airport carpark for about 4 days. However I know that the internal battery of the Maxi does not have a 4-day standby mode. Battery will almost certainly run flat. I was toying with the idea of hooking the Maxi upto a 10000mAh power bank (via USB), and leaving the settings on the MAXI to motion detect.

I'm curious is anyone can feedback, if they've attempted something similar.

 

[TonyM]

Motion detection does not consume much less power than when it is recording - after all, the sensor is constantly active while the processor analyses the scene for movement. Therefore I do not think you will get more than 24 hours from a 10000mAh power bank.

You might get a much longer recording time by using time-lapse photos at the minimum 3s interval in photo mode. I have not tried this to see if it draws less power, but I expect that it would.

Using 1080p30, it draws 1.5W and 10000mAh battery has 37Wh capacity, that means the camera will run for around 24 hours.

Did you test any photo timelapse modes?

One option might be to invest in a much higher capacity power bank such as the MaxOak 50,000 mAh (5/12 / 20v) Portable Battery Charger

or the Power Banks 30,000 mAh

There are other models on the market to chose from although Amazon USA seems to have a much wider selection of very high capacity power banks than UK Amazon.
