What You Actually Need to Know Before You Buy Security Cameras
Walk into any big box store, and you’ll find a wall of security cameras. They all look impressive on the box. They all promise crystal-clear footage, easy setup, and total peace of mind.
Then you get them home, try to figure out the app, realize the night vision barely covers your driveway, and wonder if you bought the right thing.
We’ve had this conversation with many homeowners. Here’s what actually matters when you’re choosing cameras for your home — and why where they’re placed matters as much as what you buy.
Resolution: HD Is the Starting Point, Not the Selling Point
1080p HD is now the baseline — not something worth paying extra for. If you’re investing in outdoor cameras, look for 4K options or at minimum 2K resolution. The difference matters when you need to zoom in on a face, a licence plate, or something happening 20 feet away.
Lower resolution cameras produce footage that looks fine until you actually need to use it. That’s when clients wish they’d spent a little more.
Night Vision — The Feature Most People Underestimate
The majority of security incidents happen at night or in low-light conditions. That makes night vision capability one of the most important specifications to evaluate — and one of the most misrepresented on retail packaging.
Look for cameras with colour night vision or IR (infrared) range of at least 30 feet for outdoor use. Cameras marketed with vague terms like “night mode” often produce dark, grainy footage that’s essentially unusable.
Indoor vs. Outdoor: They’re Not Interchangeable
This seems obvious, but it surprises a lot of homeowners: indoor cameras are not weatherproof and will fail outside. Outdoor cameras need an IP65 or higher weatherproof rating, and ideally a wide operating temperature range — important in Eastern Ontario winters.
The right camera for your garage is different from the right camera for your back door, which is different from the right camera for your driveway. Placement and environment should drive the selection, not the other way around.
DIY vs. Professional Installation — What Nobody Tells You
DIY cameras are genuinely fine for some situations. But there are real trade-offs that retailers don’t highlight. Many rely entirely on your home WiFi, which means they go offline if your router restarts. Most record to the cloud, which means a subscription fee in perpetuity. And the app notifications? Great in theory, exhausting in practice when every passing car triggers an alert at 2am.
Professional installation means cameras are positioned for actual coverage — not just convenience. It means wired options where reliability matters. And it means someone who’s walked hundreds of properties knows which corners, which entry points, and which blind spots to prioritize.
What a Good Camera System Actually Covers
A properly designed residential camera setup typically covers: front door and porch, garage, driveway and street approach, back yard and rear entry, and any secondary access points (side gates, basement windows).
Every home is different. The goal isn’t maximum cameras — it’s no blind spots in the areas that matter.
