    It’s electrical componentry, so conductivity and corrosion are a concern. Differential thermal expansion can also be an issue.

    The lugs are aluminium.

    The split bolts are copper or brass, tin plated for better corrosion resistance.

    None of this is going to be found in a security camera (unless they’ve earthed it with fat conductors for some reason). It’s high power gear.
