# Often observed issues
|
|
|
|
## Hardware failure
|
|
|
|
* Camera not working --> check the interface, test another module
|
|
* Low cost module with no or only 2MB memory instead of 4MB --> test another module
|
|
* SD card issues --> test another SD card
|
|
* Wifi reception bad / unstable --> bad antenna, test another module or use external antenna

This typically happens if you have suboptimal "Alignment Marks". A very simple and working solution is to put put higly contrasted stickers on your meter and put "Alignment Marks" on it (see picture below)

If after those adjustment you still have some issues, you can try to adjust your alignment settings in expert mode:

## My Analog Meter are recognized as Digit Counter or vice versa

1. First, check that your ROI are correctly defined (yey!)
|
|
2. Second, verify that the name of your ROI analog and digit ROIs are different
|
|
|
|
## Recognition is working well, but number aren't sorted correctly
|
|
|
|
You have to sort your ROI correctly (Bigger to smaller). Select your ROI and click either "move next" or "move previous". Repeat until your ROI are correctly sorted
