[Wide Compatibility with Multiple Camera Types & HD Display]: Eversecu CCTV Tester supports testing for IP cameras, analog cameras, TVI, CVI, and AHD cameras, including mainstream 4K H.264/4K H.265 cameras. Equipped with a 4-inch IPS touchscreen (800x480 resolution), it delivers high-resolution display for both network HD and analog camera feeds. Additionally, it is compatible with ONVIF PTZ and analog PTZ control, meeting diverse testing needs in installation and maintenance. [Convenient Network Testing & IP Management]: Eversecu IP camera Tester comes with rich network tools such as IP scan, PING test, Ethernet bandwidth test, DHCP server, and Trace route. The IP discovery function auto-scans IPs across the entire network segment and adjusts the tester’s IP to the same segment as detected cameras, significantly improving engineering efficiency. These tools enable quick detection of network connectivity, bandwidth status, and IP camera positions. [Flexible Power Supply for Various Scenarios]: Eversecu CCTV Tester provides 25.5W PoE power output (48V) via the LAN port, directly powering PoE-supported IP cameras without additional power sources. It also offers DC12V 3A power output, serving as a temporary power supply for cameras—ideal for on-site demonstrations, testing, and installation scenarios where power outlets are unavailable. [Professional Cable Testing Functions]: Eversecu CCTV Tester includes RJ45 cable TDR test (to detect cable pair status, length, attenuation, reflectivity, impedance, skew, etc.), UTP cable test (to check connection status and display results on the screen), and optional Cable Tracer. These functions help installers quickly identify cable faults, locate cables in messy bundles, and ensure stable network connections. [Customizable Interface & Screen Rotation]: Eversecu CCTV Tester allows users to customize the interface theme—including desktop and application background colors (via RGB values or preset options) and icon arrangements. Additionally, it supports 180-degree screen rotation, which is convenient for users to connect LAN cables at the bottom of the tester without flipping the device itself, enhancing usability in different on-site operation positions.
