6 CCTV Myths That Are Costing Kenyan Homeowners Money (and Sleep)

Every week our technicians walk into a compound where the client is convinced their CCTV system is doing something it isn't. Not because they're careless, but because the assumptions that seem logical on the surface often turn out to be wrong once you understand how these systems actually work. Here are the six myths we correct most often, and what to believe instead.

Myth 1: More cameras always means more security

A client once asked us to fit fourteen cameras on a quarter-acre plot. Fourteen. The problem wasn't ambition, it was that half of those cameras would have pointed at each other, at blank walls, or at areas already covered twice over. Camera count is not a security metric. Coverage of your actual entry points, blind corners, and high-value areas is the metric that matters.

Four well-positioned cameras covering the gate, the driveway, the back door, and the perimeter fence line will outperform ten randomly mounted units every single time. This is why a proper installer does a site walk and produces a coverage plan rather than just quoting per camera.

Myth 2: A cheap camera today saves you money

Budget cameras from unbranded suppliers often fail within twelve to eighteen months, particularly the sensor's night vision performance, which degrades fast in Kenya's dust and humidity. When that happens you're paying for a second installation, not extending the life of the first one. A genuine Hikvision or Dahua camera bought through an authorised dealer costs more upfront but is backed by a real warranty and holds its image quality for years.

Do the maths over three years, not over the first invoice. A KES 2,900 clone camera that needs replacing twice is more expensive than a KES 3,800 genuine unit that doesn't.

Myth 3: CCTV alone stops break-ins

Cameras are a deterrent and an evidence tool. They are not a physical barrier. A visible camera makes an opportunistic intruder think twice, but a determined one can still get past it if there's no fence, gate, or alarm behind it. The properties we see with the fewest incidents almost always layer CCTV with an electric fence, secure gates, and, where relevant, an alarm system. CCTV is one layer in a stack, not the whole stack.

Myth 4: Night vision means you'll see everything clearly at 2am

Standard infrared night vision gives you black-and-white footage that shows movement and rough shapes, useful, but it's not the crisp colour picture people imagine from the shop demo screen (which was almost certainly filmed in daylight). If you need to identify a face or read a number plate at night, you need starlight or white-light colour night vision cameras specifically, and they cost more for a reason.

Myth 5: Once it's installed, it looks after itself

Lenses collect dust. Hard drives fill up and start overwriting old footage faster than owners expect. Firmware goes out of date. Router changes silently break remote viewing. We've been called out more than once to a property where the client believed they had six months of recordings, only to discover the hard drive had been full and looping for the past three weeks. An annual maintenance check catches these issues before you need the footage, not after.

Myth 6: If it's not recording in 4K, it's not worth having

4K cameras produce sharper images, but they also produce far larger files, which means either a bigger hard drive or a shorter retention window. For most residential and small business applications, a properly positioned 2MP or 4MP camera captures more than enough detail for identification purposes. Resolution matters most on wide-area shots like car parks, where you need to digitally zoom into a small part of a large frame after the fact.
