</div>It depends, which type of protocol does your device support?<br>
<div><br>

<br>
</div>It depends on what the requirements are. As it's software, it's always<br>
able to be changed :)<br>

<br>
</div>What sensor are you looking for exactly?<br>
<br>
What device do you need to support, and what protocol does your camera<br>
use to talk to the hardware?<br>
