Overheating problem, also in cold weather

I've been using the H5 since late june (first version camera bought in februari 2023). I use low settings:

1080p / 60fps / medium bitrate / 60Hz / 5 minute interval clips, using a fairly new Samsung 128GB EVO plus U3 A2 V30 Class 10 MicroSd card and connected to an external large capacity powerbank.

Previously I used the low bitrate setting, which went fine for at least two hours. I've switched to medium bitrate setting and now the camera overheats... Sometimes within minutes (I then changed from 50Hz to 60Hz setting) but always within 30 minutes. I then get small videoclips, then the camera stops working. Sometimes I can feel the camera vibrating (resetting?) during a trip. I then inspect the camera and it is realy hot.

I've tried switching to the original battery, same problem. Formatted SD-card to Fat32, did a surface test -> no errors.

I've tried recording at home (low motion image since the camera is at a fixed point, pointing at the tv) and that increases the recording time to about 30 minutes before the overheating problem starts again.

Since the video can be set to 1080p/60fps/medium bitrate (30MB/s), it can't be the problem (It's a low setting compared to the maximum 4K/30fps setting).

The only time the camera worked fine, was out of the box. It was then connected to my old phone. First thing I do is do a time-update before driving, then switch off the phone. I've also updated the camera to firmware H5.C.20230213.V1.1.02

Note: The setting 1080p/60fps/low bitrate/50Hz setting seemed to produce fast playing video's. The camera also seems to stop recording when I exit the app (latest version, just updated few days ago) on my Android phone, wich is realy annoying...

Picture of how the videofiles are stored now:

I've contacted the Dutch INNOVV dealership www.camerashop24.nl where the camera originated from on the 10th of september to ask for repair, but they don't reply.

I have tested again in the open, a 3 hour trip. This time I did it like I did when I first got the camera: Time update with the app, exit the app, switch off Wifi on the phone, disconnect cam from external battery and reconnected battery when driving off. Everything went fine the whole trip (a little over 3 hrs, ni pictures taken) 🙂

Almost same settings but after a factory reset, micro-sd format, change 60 to 50Hz and about a 10 degree Celsius decrease in outside temperature. There was file structure corruption, when I tested the card after repeated failure in recording. This could have been the problem also.

I think the problem was either the weather (too ot: 35 degrees outside) sd-card corruption, or taking a picture when driving using the power on button (which also activates Wifi, Wifi might be trying to connect to a neigboring device thus using cpu cycles).

Anyway, at this moment the problem is no more, hopfully I won't have to restart this topic 😉

Thank you. Also the support dept, who has sent me information and firmware through the reseller here in the Netherlands.

Good to hear that the problem has been resolved.

I suspect file structure corruption was the problem. Taking a photo is a very short action, too short to cause such a high temperature rise. I also don't see connecting the WiFi as a problem. I have also driven in temperatures of 35 degrees and have not experienced any problems.

Either way, you can enjoy your H5 again. And that's the most important thing.

You can also leave the phone's WiFi on. The H5's WiFi switches off automatically after the time set on the WiFi timer.

I did some more temperature tests. This with high and low resolutions, bit rates, etc. The temperature remains the same in all tests, around 45 degrees Celsius. I let each test last about 4 hours in an environment of 24 degrees Celsius. The H5 was also not cooled by wind.

See in the photo how I placed the temperature sensor.

I used a FLIR camera for measurement, it could be off a little.

Again, searching for the problem, I found that the https://www.innovv.com/firmware-app]firmware update on the INNOVV website (H5 firmware:

H5.C.20230213.V1.1.02) links to https://drive.google.com/file/d/1rMQINjftaPltcZugIXJQRJPNk5cKBVg0/view this google drive file and it downloads a file named "INNOVV H5.BRN". This update changes the video codec from HEVC to AVC. Apparently the hardware can't cope with this codec, overheating the hardware and creating all kinds of problems (like accelerated playback of video?). I'd like to see a link to the original firmware, so I can revert the update please.

Hi Ray, I sent you a few older firmware versions via wetransfers.

I am doing some temperature tests myself with the same settings as you mentioned. The temperature problem could also be due to the frame rate, this is one of the things that can put more strain on the Innovv H5 processor. Higher frame rate = higher processor load. It is common knowledge that the Innovv cameras can get hot, if they do not get hotter than hand warm there is nothing to worry about. With your settings I currently measure 44*C on the outside of my H5 (after 40 minutes of recording). This is measured on the left side just behind the lens. Can you indicate how warm your H5 gets?

If you install an older firmware, do you also want to perform a factory reset? I'm curious if this will help.

Do you format the SD card in the H5 using the app?

The fast playing videos are created by the frame rate of 60fps. In Europe, between 25fps and 30fps is used. So if you record at double speed, you will get accelerated playback on playback.

The 50Hz or 60Hz settings are only intended to prevent flickering from artificial light in your recording. 50Hz is for Europe, 60Hz for the American countries.

I'll start new recording later to see if I can measure the heat. Only thing I can say is that it was far hotter than when I got the camera new, and I couldn't hold that part of the cam (behind the lens) for long. When the setting was at 50Hz, the file properties (on my PC) stated that fps was off the charts (like 1231fps), but when I used the 60Hz setting the file properties were 60fps.

The app does not have a 50fps setting (so no 1080p/50fps with 50Hz available) only 30/60fps. I would think tthat if there is a 50/60Hz setting in an app, there would also be 25/50fps (PAL) and 30/60fp (NTSC) recording.

Edit:

I use the button on the camera to sometimes take pictures for testing. There is a possiblility that the camera is then trying to connect to my phone and app. but I never have that switched on when riding. There's a possibiity that the camera and/or recording turns off if it can't connect? When I press the button, it takes the picture, but it also turns on WiFi. I use my phone for navigation, so can not see what the camera is then doing.

The 50/60Hz settings has no connection with the frame rate.

Hz and FPS are two different settings.

FPS is the number of images recorded per second.

The Hz setting is to reduce the flicker of lighting, such as light bulbs. This is because the European power grid operates at 50Hz. In the Dutch version of the app I have also translated this to 'lichtbron frequentie'.
