AHD CCTV Tester 4-in-1 — 5.0in Monitor, PTZ (Pelco-D/P) via RS485, DC12V (1A) Power Out, 4K IP Camera Tester

Portable video monitor and camera tester designed for AHD, 4-in-1 cameras and 4K IP camera checks. It features a high-resolution 5.0 inches 800 (RGB) x480 display with a wide viewing angle for clearer, more intuitive image assessment. The unit includes built-in Pelco-D / P PTZ control protocol accessible through its RS485 interface, allowing users to drive PTZ functions (up, down, left, right rotation) and adjust zoom and aperture size directly from the tester. A multi-format video OUT port serves as an image generator and can output common color standards (e.g. PAL, NTSC). The tester also provides DC12V (1A) power output to run cameras when an external supply is not available. To evaluate camera inputs, simply connect the pickup device to the tester using the appropriate cable.
