Yes, and no. Some Ansjer cameras come with an IK10 vandal proof rating, which ensures they can withstand violent impacts.
These cameras usually come with heavy-duty metal exteriors and are ideal for lower "within-reach" installations. The majority of Ansjer cameras do not come with this rating, however.
This is not to say that are totally vulnerable to vandalism though. They all come with durable exteriors (typically lightweight polycarbonate or plastic) and use vandal-resistant designs to protect their cables.
