Large Arm Mount — Required for installation. The PTZ has no direct-to-surface mount, and pole, corner and pendant cap mounts all attach to the arm rather than to the camera.
90W PoE++ Injector (802.3bt), Indoor — unless the switch already supplies 802.3bt Type 3 PoE++. The PTZ draws 48W and needs 802.3bt Type 3, past what 802.3at delivers. The injector is single-port, so it is one per camera — two PTZs cannot share one. Swap in ACC-POE-90W-E-NA if the injector sits outdoors rather than in the IDF.
