Sinotrack ST-901L vs ST-906L
I'm not sure what device is "ST901L", i just been seen ST901 with no L, but as i understand, you refer to 901 with 4G technology.
ST906L have microphone input, SOS button input, relay output, it's not waterproof. In cellphone signal coverage and gps reception, it's not significant differences.
ST901 it's waterproof, have just basic connections (+, -, IGN and Relay, thats all).
About this last one, we stopped buying this because Sinotrack has changed PCB design. In the label, up from barcode, past model that worked well had written "GPS Tracker 4G A7670SA". New model have written "GPS Tracker 4G Global". These "global" devices fails.
I'm not sure if it's because Traccar receiving issue, or if maybe something in the hardware is wrong, but that new "global" ST901s fails.
We currently just use ST906L and 915 from sinotrack manufacturer.
Greets.
Im trying to choose between these two devices. Are there any differences in terms of precision or any other important ones? I cannot seem to find any comparison between them anywhere.
