Home Security Cameras: What to Know Before You Buy

Security cameras are one of the most searched smart home products — and one of the most returned. People buy them expecting simple setup and clear footage, and end up with mounting frustrations, confusing apps, and subscription fees they did not anticipate.

The devices themselves are not the problem. The problem is buying the wrong camera for the wrong location, or not understanding what the ongoing costs and commitments look like before purchasing.

This guide covers what actually matters when choosing a security camera for a Canadian home or vacation property.

Wired vs. Wireless vs. Battery-Powered

Wired cameras connect to your home's electrical system and run a data cable back to a recorder or network switch. They provide continuous, uninterrupted power and recording with no batteries to manage. Installation is more involved — cables need to be routed through walls or along soffits — but the result is a permanent, reliable system. This is the right choice for a primary home where you want complete, ongoing coverage.

Wireless cameras connect to your Wi-Fi and are powered by an outlet. These are much easier to install than wired systems — plug in, mount, connect to app — while still providing continuous power. The limitation is that they need to be within reach of a power outlet. For most outdoor locations, this means running an outdoor extension cord or having an outlet installed nearby.

Battery-powered cameras are the easiest to install — no wiring at all — but require regular charging. At a vacation property where you are not present daily, a dead battery means no coverage, and you may not discover it for days. Battery cameras work best as supplemental coverage in specific locations, not as primary security.

Indoor vs. Outdoor Cameras

Always use an outdoor-rated camera for any exterior location. Outdoor cameras are weatherproofed, designed to operate in extreme temperatures, and built to withstand rain, snow, and condensation.

In Collingwood and Blue Mountains, temperature range matters specifically. Look for cameras rated to operate at -30°C or lower for reliable year-round performance. Battery-powered cameras, as noted above, perform poorly in deep cold — battery capacity drops significantly at low temperatures, which is another reason to favour wired or outlet-powered cameras for northern Ontario properties.

Resolution and Field of View

Most modern cameras offer 1080p resolution, which is sufficient for identifying faces and reading licence plates at reasonable distances. Some offer 2K or 4K, which provides more detail and the ability to digitally zoom into footage without losing clarity.

Field of view determines how wide an area the camera covers. A 90-degree field of view is appropriate for a focused area like a front door. A 130 to 160-degree wide-angle view covers a broader area like a driveway or backyard. For corner mounting locations, look for cameras with a 180-degree or pan-capable view.

Night vision is standard on most cameras. Look for colour night vision — which uses ambient light to produce colour footage rather than black-and-white infrared — for better clarity in low-light conditions.

Storage: Cloud vs. Local

This is the most important decision to make before purchasing, and the one most people overlook.

Cloud storage saves footage to the manufacturer's servers. You can access it from anywhere, it survives if the camera is stolen or damaged, and setup is simple. The downside is the cost — most cameras require a monthly subscription for more than a few hours of event history. Ring, Nest, and Arlo all charge $3 to $10 CAD per month per camera, or $10 to $30 CAD per month for a multi-camera plan. Over three to five years, these costs add up significantly.

Local storage saves footage to a microSD card in the camera or a network video recorder (NVR) at the property. No monthly fees, no subscription required. The limitation is that footage is only accessible from the device — if the camera is stolen, the footage may be lost with it. For properties with multiple cameras, an NVR with a hard drive is the better solution, providing local storage with remote viewing capability.

For most homeowners, a camera with local microSD storage and optional cloud backup provides the best balance — no ongoing fees for basic coverage, with the option to add cloud storage if needed.

Motion Detection and Alerts

All security cameras detect motion. The difference between a useful camera and an annoying one is how well it distinguishes between significant motion — a person walking toward the door — and irrelevant motion — a tree branch moving in the wind, a passing car, an animal.

Look for cameras with:

• Person detection: Alerts only when a person is detected, not general motion
• Motion zones: Define which areas of the frame trigger alerts, ignoring the road or neighbouring property
• Adjustable sensitivity: Tune the detection threshold to reduce false alerts
• Vehicle and package detection: Useful for driveways and front entrances

Without these controls, camera alerts become noise — notifications you start ignoring, which defeats the purpose of having the camera.

Where to Place Security Cameras

Placement determines how useful a camera actually is. The most effective locations for a typical home or vacation property:

• Front entrance: Covers the primary entry point and captures faces of anyone approaching
• Driveway: Monitors vehicle arrivals and departures, captures licence plates
• Back door or side entrance: Secondary entry points that are less visible from the street
• Garage: Particularly important at vacation properties where tools, recreational equipment, or vehicles are stored

Cameras mounted too high lose facial detail. Mount at 2.5 to 3 metres for the best balance of coverage area and subject detail. Angle downward slightly to capture faces rather than the tops of heads.

Security Camera Installation in Collingwood & Blue Mountains

I install wired and wireless security camera systems for homes and vacation properties throughout Collingwood, Blue Mountains, and Wasaga Beach. This includes camera selection, placement planning, cable routing for wired systems, app setup, and motion zone configuration — so you get useful alerts rather than constant noise.

If you are managing a vacation property remotely, I also set up remote viewing so you can check in on your property from anywhere, anytime.
