No, and please don't crosspost.

 

BRE means this thread here.

Posting the same question multiple times with doing no work on your own is going to do nothing but get people to ignore you.

If you want help then you need to clearly define all of your requirements. Connecting a security cam to a PIC. Is not a clear definition of your requirement. And you failed to provide a clear requirement in the other thread even though people asked you to define your requirements.


And once again this thread should have gone in the embedded forum but now really should be closed because it is a duplicate post.
