It is the question we get asked most often, usually while someone is standing in an aisle comparing two boxes: how many megapixels do I actually need? The short answer is that a home or small shop is well served by 2 to 3 MP, and a warehouse, office or parking lot usually wants 5 to 8 MP. The longer answer is that the number on the box matters less than most people think.<\/p>\n

What megapixels actually buy you<\/h2>\n

Megapixels are detail across the frame. More of them means you can zoom into a recording and still make out something useful \u2014 a face, a plate, a logo on a jacket. That is the whole benefit, and it only matters in proportion to how much ground the camera is covering.<\/p>\n

A camera watching a front door is looking at maybe two metres of width. A camera watching a parking lot might be covering forty. Spread the same number of pixels across twenty times the width and each face gets a twentieth of the detail. That is the real rule: resolution should match the size of the scene, not the size of your budget.<\/p>\n

Home and small shop: 2 to 3 MP is plenty<\/h2>\n

For a front door, a back door, a driveway or a small retail floor, 2 to 3 MP gives you clearly identifiable faces and readable plates at sensible distances. Going to 8 MP on a doorway camera does not make the face clearer in any way you would notice \u2014 the face was already filling enough of the frame.<\/p>\n

What it does do is quadruple the storage that camera eats. An 8 MP camera recording continuously will fill a recorder roughly four times faster than a 2 MP one. That either costs you more in drives or, more commonly, silently shortens how many days of footage you keep \u2014 which is the one thing you actually need when something happens.<\/p>\n

Warehouse, office and parking lot: 5 to 8 MP<\/h2>\n

Here the extra resolution earns its keep, because the scenes are genuinely large. A camera covering a loading bay or a yard needs the detail to survive being zoomed into. This is also where a single higher-resolution camera can replace two lower-resolution ones, which usually works out cheaper once you count the cable runs.<\/p>\n

Four things that matter more than the megapixel count<\/h2>\n

The lens.<\/strong> Resolution is meaningless if the optics are soft or the field of view is wrong for the space. A cheap 8 MP camera with a poor lens produces a sharp recording of a blurry image.<\/p>\n

Night performance.<\/strong> Most incidents happen in the dark. A camera’s low-light sensitivity and the quality of its infrared matter far more, at 2am, than its daytime resolution. This is where budget cameras fall down hardest and where spec sheets are least honest.<\/p>\n

Placement.<\/strong> A well-aimed 2 MP camera beats a badly aimed 8 MP one every time. Mounting height, angle and distance decide whether you get a usable face or the top of a hood.<\/p>\n

The recorder.<\/strong> High-resolution cameras need a recorder that can handle the bandwidth and the storage. Pairing 8 MP cameras with an undersized recorder means either dropped frames or a recording window measured in days.<\/p>\n

What we recommend for Kitchener-Waterloo homes and businesses<\/h2>\n

For a typical home around here, we normally spec 2 to 3 MP at the doors and a slightly higher resolution at the driveway, because the driveways in this region tend to be long. That difference matters more than any single spec: a 40-metre driveway in Waterloo needs a different lens and a different resolution than a 10-metre one in a townhouse development.<\/p>\n

For commercial sites \u2014 the industrial units around Cambridge, warehouse yards, farm properties out toward Guelph \u2014 we are usually at 5 to 8 MP on the wide scenes and pairing that with proper night-capable cameras at the gates. Winter is a real factor here too: snow glare and low sun in the late afternoon will wash out a poorly placed camera regardless of how many megapixels it has.<\/p>\n

The honest summary is that we would rather sell you four cameras specced properly for their spots than eight identical ones chosen off a spec sheet.<\/p>\n

FAQ<\/h2>\n

Is 4K CCTV worth it for a house?<\/h3>\n

Rarely. 4K (8 MP) makes sense on large open scenes. On a doorway or a garage it mostly consumes storage without giving you detail you would ever use.<\/p>\n

Will higher megapixels help me read licence plates?<\/h3>\n

Somewhat, but placement and lens choice matter far more. A camera angled across a driveway will struggle at any resolution; one aimed along the direction of travel, at the right height, will read plates reliably at 3 MP.<\/p>\n

How much storage do I need?<\/h3>\n

It depends on resolution, frame rate and how many cameras you run, but plan for at least two weeks of footage. If adding resolution cuts that window below two weeks, the resolution is costing you more than it is giving you.<\/p>\n

If you are planning cameras for a property or business in Kitchener, Waterloo, Cambridge or Guelph, we will do a free site survey and spec each camera for the spot it is actually covering.
