And your morals involve insecure borders? No one's getting deported.
The implication of your argument is that cameras make borders more secure and therefore it's a good idea to have them. Cameras obviously don't stop people crossing a border physically like a wall would, so the only possible way they'll improve security is by providing evidence of who crossed. Your assertion that "No one's getting deported" is obviously wrong - if that were the case there'd be no need to have the cameras in the first place.
Deportations are happening at a rapid pace. No, the cameras may not be part of the current deportation / ICE frenzy, but working on them would put the engineer on the side of the Immigration establishment. From that point of view, it's a moral choice even if the specific object in question, a camera, is not immoral on its own.
I can deeply respect anyone who would refuse to aid the current government's immigration policies in any way, and I would refuse to do so myself.
