Choosing between wired and wireless cameras
The first decision in any home security camera installation is whether to use wired or wireless hardware. Each approach involves trade-offs that are sharpened by Canadian climate conditions.
Wired cameras (PoE)
Power over Ethernet (PoE) cameras receive both power and data through a single CAT5e or CAT6 cable. This eliminates battery replacement and offers a more stable video feed, but requires routing Ethernet cable from a central PoE switch or NVR to each camera location. In cold climates, cable routing through exterior walls should use exterior-rated conduit to prevent moisture ingress from freeze-thaw cycles. For finished interiors, plan on fishing cable through existing cavities before winter weather makes attic access uncomfortable.
Wireless cameras
Wi-Fi cameras are easier to install but depend on network reliability. A camera placed at the far end of a detached garage or a rear corner of a property may fall outside reliable Wi-Fi range. Mesh networking systems can extend coverage, but each hop through a mesh node adds latency and can affect live video quality. Battery-powered wireless cameras avoid the wiring problem entirely but need recharging or battery replacement; in sub-zero temperatures, lithium batteries lose capacity significantly, which shortens the interval between charges in winter months.
Cold-weather performance
Check the operating temperature range on any camera intended for outdoor installation. Many cameras are rated to -20°C or lower, but some budget models are only rated to 0°C and will fail during a Canadian winter. Cameras rated to -40°C are available and appropriate for northern regions.
Camera placement principles
Effective camera placement follows a few consistent principles regardless of home size or camera model.
Entry points first
Front door, back door, garage entrance, and any side gate are the highest-priority positions. A camera at each entry point captures both approaching and departing movement. Position entry cameras at 2.4 to 3 metres height — low enough to capture faces clearly, high enough to be out of easy reach. Cameras placed directly above a door in a downward angle capture the top of heads rather than faces; a slight outward angle from a wall-mounted bracket solves this.
Perimeter coverage
After entry points, consider driveway coverage and any blind spots along the building perimeter. A wide-angle camera (90–130 degree field of view) covering the driveway from one corner of the house can capture vehicle movement without requiring a separate camera at every corner. Avoid pointing cameras directly at the street or at neighbouring properties — see the PIPEDA section below.
Interior placement
Interior cameras are typically placed in common areas: entrance hallways, living rooms, and garages. Bedroom and bathroom placement raises both privacy and legal concerns and is outside the scope of typical residential security setups. A camera facing a main door from inside captures anyone entering, which is useful for verifying package delivery or monitoring for forced entry.

Installation: wired PoE camera system
The following describes a typical NVR-based wired installation for a single-family home.
Equipment list
- PoE NVR (Network Video Recorder) with built-in PoE switch — typically 4 or 8 port
- PoE IP cameras (matching brand or ONVIF-compatible)
- CAT6 cable — exterior-rated if any run passes outside the building envelope
- RJ45 connectors and crimping tool, or pre-terminated cable runs
- Cable clips or conduit for routing
- External hard drive or NVR internal storage
Cable routing
Plan cable routes before drilling. Each camera requires one cable run back to the NVR location (usually a basement utility room or wiring closet). For exterior cameras, drill through the wall close to the soffit or just below the eave to minimise exposure. Apply exterior-grade silicone caulk around any penetrations after routing the cable. Seal from the outside; do not rely on interior caulking alone.
NVR placement
Place the NVR in a location that is not visible from windows or doors, and ensure it has adequate ventilation. Hard drive temperature affects lifespan — avoid uninsulated garage installations in regions with winter temperatures below -10°C unless the NVR is rated for those conditions.
PIPEDA privacy requirements for Canadian homeowners
Canada's Personal Information Protection and Electronic Documents Act (PIPEDA) applies to the collection and use of personal information, including video footage. For residential security cameras, the Office of the Privacy Commissioner of Canada has published guidance indicating that cameras capturing only private property (your home, yard, driveway) are generally not subject to PIPEDA. However, cameras that capture public streets or neighbours' properties enter a grey area that can raise legal and neighbour relations issues.
Practical steps to stay within reasonable privacy bounds:
- Angle cameras to capture your property, not the sidewalk or neighbouring yards
- If cameras are visible, consider posting a small notice that the property is monitored — this is not legally required for residential use but is considered a courtesy
- Retain recordings only as long as needed — overwriting footage after 14–30 days is a common practice
- Do not share footage publicly without removing identifiable individuals unless required by police
For more detailed guidance, the Office of the Privacy Commissioner of Canada (priv.gc.ca) publishes residential surveillance guidance.
Connecting cameras to cloud and local storage
Most consumer cameras offer cloud storage subscriptions for recorded footage. Cloud storage provides remote access without maintaining local hardware, but involves ongoing subscription costs and means footage is stored on third-party servers. Local NVR or NAS-based storage keeps footage on-premises and has no recurring cost after initial hardware purchase, but requires managing storage capacity and ensuring the device is accessible for remote viewing through a secure method (VPN or camera system's own remote access).
Storage estimate
A single 1080p camera recording continuously at medium quality generates roughly 15–25 GB of footage per day. A four-camera system recording continuously would fill 1 TB in approximately 10–16 days. Motion-triggered recording significantly reduces storage use — most systems capture one-tenth of that amount in typical residential settings.
Connecting to smart home systems
Many PoE and Wi-Fi cameras can be integrated into broader smart home setups. Google Home and Amazon Alexa both support camera brands including Ring, Nest, and Arlo for live view on smart displays. Apple HomeKit requires HomeKit Secure Video-compatible cameras (Logitech Circle View, Eufy, Eve Cam) and routes recordings through iCloud with end-to-end encryption.
