What Is This 4 In 1 Network Cable Tester Used For?
This 4-in-1 network cable tester is used to check whether a cable is properly connected from one end to the other. It helps identify wiring problems before the cable is used with a router, switch, CCTV system, telephone line, USB device, or BNC connection.
It is useful after making a new cable, repairing a damaged connector, or troubleshooting a network connection that is not working properly.
Which Cables Can This Tester Check?
This tester can check RJ45, RJ11, RJ12, USB, and BNC cables. RJ45 is commonly used for Ethernet and LAN cables. RJ11 and RJ12 are used for telephone-style connections. USB is used for data cables, while BNC is commonly used in CCTV and coaxial cable setups.
Because it supports several cable types, it is more flexible than a basic RJ45-only tester.
Is This Tester Good for RJ45 LAN Cables?
Yes, this tester is useful for RJ45 LAN cables used with routers, switches, computers, network printers, patch panels, and CCTV IP cameras.
After crimping an RJ45 connector, you can test the cable before installing it permanently. This helps avoid connection problems caused by wrong wire order or weak crimping.
Is It Useful for CCTV Installers?
Yes, this tester is useful for CCTV installers because it supports both RJ45 and BNC cable testing. RJ45 is commonly used for IP camera systems, while BNC is used in many coaxial CCTV camera setups.
A tester can help confirm cable condition before connecting cameras, DVRs, NVRs, routers, and switches.
Can It Help Find Cable Faults?
Yes, a cable tester can help identify basic cable faults such as open wires, wrong wiring order, crossed wires, shorts, and poor connector termination.
It is especially useful when the cable looks fine from outside but the internet, camera, telephone, or device connection is not working.
Who Should Buy This Cable Tester?
This cable tester is suitable for IT technicians, network installers, CCTV installers, telecom workers, computer shop owners, office maintenance teams, students, freelancers, and home users.
It is a practical tool for anyone who makes, repairs, installs, or troubleshoots network and communication cables.
What Should You Use With This Tester?
For complete cable installation work, use this tester with an RJ45 crimping tool, RJ45 connectors, Cat5e/Cat6 LAN cable, telephone cable, USB cable, BNC cable, network switch, router, and cable ties.
For professional work, keep it in the same toolkit as your crimping tool so every cable can be tested immediately after crimping.
