How to run power for outdoor security cameras?

Running power for outdoor security cameras requires proper weatherproof wiring and typically needs a TSANB permit in New Brunswick. Most installations require a licensed electrician to ensure code compliance and safety in our Maritime climate.

Power Options for Security Cameras

The most reliable approach is running dedicated 120V circuits to each camera location. This involves installing weatherproof junction boxes and using appropriate cable rated for direct burial or exterior mounting. In New Brunswick's harsh Maritime climate with ice storms, salt air, and temperature extremes, proper installation is critical to prevent failures and safety hazards.

For multiple cameras, you can install a central power supply in a weatherproof enclosure and run low-voltage DC wiring to each camera. This reduces the number of electrical permits needed since only the main power feed requires TSANB approval. However, voltage drop over long distances can be an issue with low-voltage systems.

Canadian Electrical Code Requirements

Under the CEC as adopted by New Brunswick, outdoor electrical installations must meet specific requirements. All outdoor outlets and junction boxes need GFCI protection and must be rated for wet locations. Buried cable must be at least 600mm deep (deeper in areas with heavy frost like most of NB) and use appropriate direct-burial rated wire. Any new circuits require TSANB permits and inspection.

Conduit runs on exterior walls must use weatherproof fittings and be properly sealed. In coastal areas like Saint John or Moncton, marine-grade components may be necessary due to salt air corrosion. The electrical connections must be accessible for future maintenance while remaining weatherproof.

Installation Considerations for New Brunswick

Our Maritime climate creates unique challenges. Ice storms can damage improperly secured wiring, and the freeze-thaw cycle can crack poorly sealed junction boxes. Plan cable routes to avoid areas where ice might fall from roofs. Consider underground runs where possible to protect from weather damage.

For existing homes, running new circuits often means accessing the electrical panel and routing cable through walls or underground. This work requires a licensed electrician and TSANB permit. The electrician will need to verify your panel has capacity for additional circuits and install appropriate GFCI protection.

Safety and Legal Requirements

Never attempt to run 120V circuits yourself - this work must be done by a TSANB-licensed electrician in New Brunswick. DIY electrical work violates code, voids insurance, and creates fire and electrocution risks. Even low-voltage camera wiring should connect to properly installed electrical systems.

If you're installing a comprehensive security system, coordinate with your electrician early in the planning process. They can design circuits to minimize permit requirements while ensuring reliable power for your cameras.
