My experience with motion detection ON and firmware 1.13 is totally different. I'll explain, but first I want to describe my setup: Mobius with 3m power cable (from the same seller); Mobuis gets powered with the ignition key in the ACC position, and obviously, the power is cut when the key goes to OFF position. Settings: auto start recording (or whatever its called): external only, MD: on; sensitivity: high, timeout: 60s.
Why am I writing about this now: because at first I thought I didn't even turned motion detection ON - it was working THAT good...and because, when I "upgraded" to 2.10 it sucked big time, so I reverted to 1.13...and because my experience with MD is different that all the others' from this thread. I'll try to explain:
1. When I turn key to ACC position, the camera turns on AND starts recording imidiatelly. Red indicator light is blinking and when I check after drive, there is video saved. I presume it would be recording for 60 seconds, but I drive off before that timeout.
2. It recorded every single second of my around 10 hour drive throughout 3 days (daylight and night driving combined), except a few minutes when I was stationary, entering my satnav data with the key in ACC position, and while there was actually no movement at all. Even the videos that were recorded in these situations (a car passing by, thus triggering MD) were exactly 1:01 long (I'll explain later why is that important).
3. The bast part, and the part that is totally different than anything from this thread - with the power cut, Mobius would record for 10 seconds (option I chose), would close the last file and would TURN OFF. O.O
4. I didn't try it myself, I admit, but there is absolutely no reason that it wouldn't work if started manually, on battery alone, making it a perfect parking camera in MD mode (until the battery is depleted, obviously).
Why is this such a surprise to me: I wanted to try Mobius in MD mode, but I've also read a lot of threads from this (and other) forum. I thought I turned MD on in the settings, but then, when I was driving, I noticed that it recorded all the time, and that it would turn off every single time (with the delay of 10 seconds) when I would turn off the car. At that point I thought I actually forgot to turn MD on since it worked the same way as it did with MD off. Only on the third night, I checked my videos at home, saw a few 1:01 long videos (mentioned above) and that made me check the settings and that is when I saw that MD was ON all the time.
In short: with fw 1.13, and setup+settings I already mentioned, my Mobius turns on and starts recording every single time I turn key to ACC position (and beyond), records everything while there is movement, stops recording when there is no movement for 60 seconds, and turns off COMPLETELY after the key is switched to off position. All that with the ability to be used as parking camera (this has to be turned on manually) on battery, when needed.
Fast forward a few days: there is an "upgrade" - a brand new 2.10 firmware. Beautiful new options, low light setting, great customization, etc. I upgrade my Mobius, and leave crucial settings the same, MD on, auto record on external power, MD timeout 60s, high sensitivity, etc. The result: the camera doesn't correctly detects movements...it sometimes timeouts after 20 sec., sometimes after 35 seconds, and sometimes after 60 seconds as it should, after the last (very noticable, I might add) visible movement. Totally random timeout (or wrong/non-existing movement detection). Sometimes it doesn't even detect (very noticable, I might add) visible movement. I should notice that I've been testing fw 2.10 only in the night. Plus, after powering it on, it needs initial movement to start recording (logical behaviour, I know) but I liked how it imidiatelly started recording with 1.13, as soon as the power was on.
Not realted to MD: with the camera in low light mode, the flickering was all over the place, even when everything is stationary, no movement, no moving lights etc. Not only that, but the video becomes really grainy and really jerky during those moments when scene is "lighted" (in a lack of a better term), while flickering occurs...and while scene is "dimmed", video is normal, not grainy (for a night time recording) and not jerky. You probably already understand that I am back to fw 1.13 and can't be happier.
