Which of the following is NOT considered a specialty CCTV tool?

The correct choice highlights that a tone generator with a probe is not specifically categorized as a specialty tool for CCTV systems. In the context of CCTV, specialty tools are those that are uniquely designed to aid in the installation, maintenance, or troubleshooting of video surveillance systems.

Camera lens cleaners are essential for maintaining clear images, and monitor calibrators are crucial for ensuring that video displays show accurate color and brightness, both of which are critical for effective surveillance. Signal testers are also specialized tools used to check the integrity and quality of video signals within CCTV setups.

On the other hand, a tone generator with a probe is primarily utilized in telecommunications to trace and identify wires or cables in various types of networks. While it may assist in identifying cable pathways, it does not specifically enhance or support the functionality of CCTV systems. This distinction makes it less relevant to CCTV applications.
