What is the best way to wire a home security camera system in the GTA?

The best approach for a reliable home security camera system in the GTA is a hardwired PoE (Power over Ethernet) setup, which runs a single Cat6 cable to each camera location providing both data and power. While wireless cameras are easier to install, they suffer from WiFi interference, battery maintenance, and signal drop-off — problems that are especially frustrating during Toronto's harsh winters when you need your system most.

A PoE camera system uses a central NVR (Network Video Recorder) or PoE switch, typically located in your basement or utility room near your router. From there, individual Cat6 cable runs go to each camera location — front door, back door, driveway, garage, side yard, and any other coverage points. Each cable run carries both the video signal and the electrical power to the camera, eliminating the need for separate power outlets at each camera location. A quality 8-channel PoE NVR system with four to six cameras costs $400 to $1,200 for the equipment, and professional installation including cable runs typically adds $800 to $2,000 depending on the number of cameras and complexity of the cable routing.

For GTA homes, there are specific considerations worth planning for. Exterior cable penetrations must be properly sealed — Toronto's freeze-thaw cycles will drive moisture into any gap, causing corrosion and eventual cable failure. Your electrician should use weatherproof junction boxes rated for outdoor use and seal all penetrations with appropriate caulking. Camera placement matters too — position cameras under soffits or eaves where possible to protect them from direct ice and snow accumulation. Cameras rated to at least -30 degrees Celsius are essential for reliable winter operation in the GTA.

Condo Considerations

If you live in a condo, your options are more limited. Most condo boards do not permit exterior camera mounting on common elements, and drilling through exterior walls typically requires board approval. Interior cameras and doorbell cameras (mounted on your unit's door frame) are usually permitted without approval. Check your condo declaration and rules before planning any installation.

The electrical side of a PoE camera system is relatively straightforward — a dedicated 15A or 20A circuit to your NVR location and a proper grounding connection. If you are running cables through walls, an ESA permit may be required for the electrical portion of the work. A licensed electrician experienced in low-voltage systems can handle the entire installation. Browse electrical professionals in your area through the Toronto Construction Network directory to find someone who specializes in security and structured cabling.
