Camerinus Antistius Vetus was a Roman senator, who was active during the reign of Claudius.
However, the Fasti Teanenses, which reveals many details about the consuls of this period, omit all mention of Camerinus; it credits Sulpicius Camerinus with holding the office from the beginning of March through the end of June.
A number of explanations have been proposed to explain Camerinus Antistius omission, but Nikolaus Pachowiak points out they are all unsatisfactory.
Pachowiak remarks that it should not be a surprise that the literary tradition only knows him by his first three names, pointing to Galba and noting that Suetonius is the only literary source from which we learn the emperor had adopted the names Lucius Livius Ocella.
[7] While it would be the simplest solution -- this provides a pre-consular career for Sulpicius Camerinus, and a post-consular career for Antistius Vetus -- and there is no evidence against it, more evidence is needed before Pachowiak's identification is accepted as fact.
