He Meets His Match, the Grisly Ghoul (2) - S1-E16
Factual error: Dick Grayson's mini-camera, which is sitting on the bar, takes several shots of the villains from impossible angles several feet away from its location. And though he conspicuously places the camera in plain view, the crooks never notice it. (00:10:40)
Answer: It's wasn't unusual for multiple actors to play one character on this show. The villains on the TV Batman were played by guest stars, not regular cast members. George Sanders, Otto Preminger, and Eli Wallach played the part at various times. They may simply have only wanted to play the part once or twice, or they were later tied up with other projects, making it necessary to cast someone else. Other characters, like Catwoman, were also played by more than one actress.
