Why do cheap security systems fail within three years?

The number you compare is not the thing you are buying

Three quotes for the same entrance arrive within a few percent of each other and one is lower. The assumption is that they describe the same system at different margins. They do not. They describe different systems, and the difference is invisible on the day you choose.

What a lower number removes first is never a camera or a reader. It is the work between them: the interlock, the containment, the commissioning record, the as-built drawing that matches what was actually installed. Those items have no line of their own, so they are the cheapest thing to leave out and the only thing that cannot be added later without opening a wall.

The same entrance, three specifications

From the company profile. The same doorway, quoted at three levels, so the budget conversation becomes a choice rather than a negotiation.

1. Tier one

   Essential

   Card or fingerprint on a controlled door, proper request-to-exit, fire-triggered release. Attendance exported for payroll. Correct on paper, and it queues.

2. Tier two

   Recommended

   Face recognition on a purpose-lit entry with turnstiles, entry and exit on one line with anti-passback so attendance is real. Contractors on a separate credential class.

3. Tier three

   Best in class

   Speed gates sized for peak throughput, two-factor on controlled areas, mobile credential so nothing is carried, and live mustering on the fire panel trigger.

Tier one is not a bad system. It is a correct system with the coordination removed, and the removal is what shows up at shift change.

What fails, in the order it fails

The design horizon every specification should be written against is a seven to ten year service life. A lowest-bid installation is written against the handover date instead, and the gap between those two horizons is the whole argument.

1. Year one. Everything passes its own commissioning test. Each system works. The building does not, because no single test covered the joins.
2. Year two. The first interlock is discovered missing. Usually during a drill, occasionally during an event. Nobody accepts it as their scope, because it genuinely was not in anyone’s.
3. Year three. Warranties lapse, spares are not held, and the first component failure becomes a procurement exercise rather than a service call. Recording gaps begin, and they are found only when footage is requested.
4. Year five. Replacement is being quoted for equipment that should have had years left in it. The documentation to specify that replacement does not exist, so the estate is priced from scratch a second time.

On a lowest-bid installation the outer limit is short: equipment specified against the handover date rather than a service life is replaced within two to three years. That is the ceiling, not the average. Some of it lasts longer, and none of it lasts as long as the seven to ten years the specification should have been written against.

Why we stopped competing on the lowest number

“We do not compete on the lowest upfront number. We compete on year seven.”

In 2016 the work changed. Building management and automation joined the four systems already under one roof, and coordinating five trades across a live site stopped being an installation problem and became an engineering one. From that point the lowest bid was a contest we could not win honestly. Not because the equipment would be worse, but because winning it would mean pricing out the interfaces, and the interfaces are the product.

Most facilities are secured by a collection of separately procured products that were never asked to work together. Each one passes its own test. The gaps between them belong to nobody, and the gaps are where every serious failure lives.

What to ask before you accept the lower number

• Which interfaces are in this scope, and which are assumed to be in somebody else’s?
• Who witnesses the cause-and-effect test, and what document records it?
• What retention is the storage actually sized for, at the frame rate quoted?
• What is held as spares, and by whom?
• What do the as-built drawings show on the day of handover?

A quote that answers all five is rarely the lowest one. It is usually the only one that can be compared to anything.
