Two quotes for the same job, and one is much cheaper. The obvious conclusion is that somebody is taking a bigger margin, or that the cheaper installer is hungrier.
Occasionally that is true. Far more often the two documents describe different systems, and the difference is not quality — it is how much of the property ends up on camera.
A worked example
A site needed cameras across two locations. Three options were prepared for the same brief.
Option 1 — full IP. A 32-channel recorder, dual drives, two 16-port PoE switches, and 22 cameras at the main site. A second, smaller recorder and four more cameras at the other location, linked so both could be viewed together. Everything new, room to expand.
Option 2 — analogue. A 16-channel recorder, reusing some existing cabling and the existing power supplies. Same cabinet, same power protection. And 16 cameras.
Option 3 — cheapest. As option 2, but without the cabinet or the detailed installation work.
Look at the camera counts again. The gap between option 1 and option 2 is not a discount. It is six cameras.
Where the six cameras went
They were not removed to save money on cameras. They were removed because of the recorder.
An analogue DVR has a fixed channel count, and a 16-channel DVR records sixteen cameras. Not seventeen. The brief called for twenty-two views, so choosing the cheaper recorder deleted six of them — and the six that go are, by definition, the ones somebody decided mattered least. Nobody ever documents which six, or what they were watching.
This is the single most useful thing to understand when comparing CCTV quotes: the recorder sets the ceiling. Everything else on the page is negotiable; that number is not. A site quoted on a 16-channel recorder is a 16-camera site for the life of that recorder, and adding the seventeenth camera later means buying a second recorder — at which point the “saving” is gone and you have two systems to manage instead of one.
The IP option carried a 32-channel recorder for 22 cameras. That was not over-specification. It was ten channels of headroom on a site that would obviously grow.
Read the channel count before the total
When you have two quotes side by side, compare in this order:
- Channel count of the recorder. This is the ceiling. Compare it against the number of cameras quoted and against what the site will plausibly need in five years.
- Camera count. If they differ, the quotes are not comparable and no price comparison means anything until you know which views were dropped.
- Storage. Drive capacity against camera count and resolution determines retention. A big camera count on a small drive is a system that records everything for a fortnight.
- What is reused versus replaced. Reuse is legitimate and often sensible. It should still be stated.
- Then the total.
Most people read that list bottom to top, which is how two genuinely different systems end up being compared on price alone.
Reuse is not the same as cutting corners
The analogue option in this example deliberately reused existing cabling and existing power supplies. That is a legitimate engineering decision, not a compromise — on a retrofit, existing coax in the walls has real value, and HD-over-coax technologies exist precisely so that cable does not have to be ripped out.
The distinction that matters is whether reuse is stated. A quote that says “will use existing power supplies” is being honest about a dependency: if those supplies turn out to be failing, that is a variation, and everybody knows it in advance. A quote that silently assumes reuse looks cheaper and becomes expensive later.
Ask directly: what on this quote depends on something that is already here, and what happens if it does not work?
The parts people delete first
Between option 2 and option 3, what disappeared was the cabinet and the installation detail. Those are the classic deletions, because neither is a camera and neither is visible in the app.
What the cabinet was actually doing on this specification: a glass-fronted enclosure with full-length shelves, fan panelling and heat-extraction fans, and 16 A power banks with over-voltage protection.
That is not furniture. It is thermal management and power protection for the one device that holds all the footage. A recorder sitting on a shelf in a warm room, on unprotected power, is the component most likely to fail — and its failure is not one camera going dark, it is every camera and every recording.
Deleting the cabinet saves a line on the quote and moves the risk onto the recorder. On the coast, in a KwaZulu-Natal summer, in a building with an unreliable supply, that is a poor trade.
On going cheaper still
There is a floor below which the equipment itself becomes the problem: unreliable recorders, cameras whose firmware is never updated, apps that stop working after a phone update, and no local support when something fails. It is difficult for the owner and difficult for whoever has to maintain it, and it usually gets replaced within a few years.
That is worth saying to a client plainly rather than quietly quoting it because it is what they asked for.
What to ask about any CCTV quote
- How many channels is the recorder, and how many cameras am I getting?
- If I want more cameras later, what does that cost — a camera, or a new recorder?
- How many days of footage will this actually hold, at these settings?
- What here is being reused, and what happens if it fails?
- Where does the recorder live, and what protects it from heat and power?
- Which views did you decide not to cover, and why?
That last one is the most revealing question you can ask, and almost nobody asks it.
