4in1 CCTV Test Monitor — a single tool to install, configure, and troubleshoot multiple camera types quickly and accurately. Key benefits Multiformat compatibility: Test CVBS, AHD (up to 8MP), TVI (up to 8MP), and CVI (up to 8MP) cameras with one device. No need to carry separate testers for different camera standards. Audio verification: Accepts an audio input and plays it through the builtin speaker so you can confirm microphone and audiochannel operation onsite. Onsite power for testing: Uses external DC 5V (2A) power input and provides a temporary power output of 12V 1A to power cameras during setup and diagnostics. PTZ configuration and control: Builtin PTZ controller supports PelcoD/P and similar protocols via RS485. Control pan/tilt and rotate up/down/left/right and adjust zoom, focus, and iris without returning to the recorder. Faster, more accurate commissioning: Combines video, audio, power, and PTZ control to reduce trips, speed diagnostics, and ensure cameras are positioned and configured correctly before final handover. Main features Video formats supported: CVBS, AHD 8MP, TVI 8MP, CVI 8MP. Audio test: Audio input accepted and played through internal speaker for immediate verification. Power: External power supply DC 5V (2A). Temporary power output 12V 1A to power cameras during testing. PTZ control: RS485 interface supporting PelcoD/P and similar protocols. Control pan/tilt and adjust zoom, focus, and aperture (iris). Practical use scenarios installations: Use the monitor to verify video feeds, confirm audio from microphones, power cameras temporarily, and set PTZ presets while on the ladder or roof — then hand the system over confirmed and ready. Field troubleshooting and maintenance: Quickly identify bad video signals, verify audio paths, and exercise PTZ movement on suspect cameras without needing the full DVR/NVR system onsite. System upgrades and testing: Validate camera output after replacing a camera or upgrading cabling; use the temporary 12V output to power a camera for immediate test imaging and PTZ setup. Why this tester matters Consolidates functions required for typical CCTV deployment and maintenance into one unit, reducing equipment load and onsite time. Ensures both picture and audio channels are testable and PTZ functions are configurable without extra interfaces. Provides temporary power so technicians can test cameras even before permanent power wiring or power supplies are connected. Note: Supports the listed video formats, audio input played via the internal speaker, external DC 5V (2A) power supply, temporary 12V 1A camera power output, and PTZ control over RS485 with PelcoD/P protocol compatibility.
