Legacy Surveillance Wiring Installation Guide216

Installing a surveillance system requires proper wiring to ensure reliable and efficient operation. This guide will provide a comprehensive overview of installing wiring for legacy surveillance systems, focusing on the traditional analog and digital technologies used in older systems.Types of Surveillance Wiring

There are two main types of wiring used in surveillance systems:* Coaxial Cable: Typically used for analog cameras, coaxial cable transmits video signals over copper wires.
* Unshielded Twisted Pair (UTP) Cable: Used for digital cameras and other devices that require Ethernet connections.
Choosing the Right Wire Gauge

The gauge of the wire determines its thickness and current-carrying capacity. For surveillance applications, the following gauges are recommended:* Coaxial Cable: RG59 for short runs (up to 200ft), RG6 for medium runs (up to 500ft), RG11 for long runs (over 500ft)
* UTP Cable: Category 5e or higher (Cat6 preferred) for high-speed data transmission
Wire Routing

Plan the wire routing carefully to avoid signal interference and damage. Consider the following:* Conduit: Protect wires by running them through conduit or other protective piping.
* Avoid Power Lines: Keep wires away from power lines and other sources of electromagnetic interference.
* Securely Mount Wires: Use cable ties or clips to secure wires and prevent sagging or damage.
Connecting Devices

Connect wires to devices using appropriate connectors:* Coaxial Cameras: BNC connectors
* Digital Cameras: RJ45 connectors
* DVR/NVR: BNC or RJ45 connectors
Terminating Wires

Properly terminate wires to the connectors. For coaxial cable, use crimp-type connectors or solder them in place. For UTP cable, use keystone jacks or punch-down blocks.Testing the Wiring

Before connecting the system to devices, test the wiring to ensure continuity and proper operation. Use a cable tester to verify that the wires are undamaged and the connections are secure.Additional Considerations
* Lightning Protection: Install lightning protection devices at the entry point of the wiring into the building.
* Grounding: Ground the surveillance system and all devices to a proper electrical ground.
* Labeling: Label wires and connections clearly for future maintenance and troubleshooting.
Troubleshooting

If you encounter any issues with the wiring, follow these troubleshooting steps:* Check Connections: Ensure that all connections are tight and secure.
* Test the Cables: Use a cable tester to verify that the wires are not damaged.
* Check the Connectors: Inspect the connectors for damage or corrosion.
* Isolate the Problem: Disconnect devices one at a time to identify the source of the issue.
Conclusion

Installing surveillance wiring is an important step in setting up a reliable and effective surveillance system. By following the guidelines outlined in this guide, you can ensure that your wiring is properly installed and will provide years of trouble-free operation.
