Durable & trustworthy – that is not just a slogan; it is what every FARHD product proves before it leaves our factory.

In the world of security and access control, there is no room for “maybe it works.” When a resident presses the doorbell, when a property manager needs to unlock a gate remotely, or when a visitor expects a clear video feed – the system must respond instantly, every single time. That level of reliability does not happen by accident. It is engineered, tested, and verified – often in ways that customers never see.

One of the most critical steps in our manufacturing process is the continuous aging test. This is not a quick spot check. It is a rigorous, hours‑long stress test that every FARHD video intercom unit must pass before it can be packaged and shipped.

What Is a Continuous Aging Test?

An aging test (often called a burn‑in test) is a process where electronic devices are operated continuously under controlled conditions – sometimes with elevated temperature or voltage – to expose any latent defects. The principle is simple: if a component, solder joint, or firmware module is going to fail early, it is far better for it to fail in our factory than on your building’s entrance.

During the aging test, each unit undergoes:

• Continuous power‑on – typically 12 to 72 hours, depending on the product type
• Repetitive simulated calls – the outdoor station calls the indoor monitor dozens or hundreds of times
• Uninterrupted video streaming – the camera feeds live video to the monitor for the entire test duration
• Frequent relay triggers – unlock signals are sent repeatedly to verify consistent operation
• Audio loop tests – two‑way communication is checked for clarity and absence of echo or noise

All this happens while the products are often placed in an aging room with elevated ambient temperature (e.g., +40°C to +60°C) to accelerate thermal stress.

Why Continuous Testing Matters

Many manufacturers perform only a brief functional test – power on, press a button, see an image, and ship. That catches obvious defects: a dead camera, a broken speaker, a non‑responsive screen. But it does not catch:

• Intermittent connection issues – a wire that is barely making contact may work for 10 minutes but fail after hours of vibration and thermal expansion.
• Firmware memory leaks – some bugs cause a system to crash only after hours of uptime.
• Component drift – capacitors or regulators might perform within spec when cold but drift out of spec as they heat up over hours.
• Display or touchscreen degradation – occasional flickering or dead zones may appear only after the screen has been on for an extended period.

The continuous aging test exposes these hidden weaknesses. By running the system for hours (or days) non‑stop, we ensure that every unit is not just functional – it is stable and reliable under sustained use.

What We Verify During Aging

Test Aspect	What We Look For
Video stability	No freezing, flickering, colour distortion, or signal loss.
Audio quality	Clear, full‑duplex communication with no echo, static, or dropouts.
Call response	Every simulated call is answered promptly; no missed rings.
Relay operation	Unlock signals fire consistently and at the correct timing.
Touchscreen (if applicable)	All touch zones remain responsive; no dead areas.
Network connectivity (IP models)	Stable IP communication, no disconnections or packet loss.
Night vision switching	IR cut filter and IR LEDs activate/deactivate correctly.
Thermal performance	No overheating, no thermal shutdown, no performance degradation.

Any unit that shows even a single anomaly is removed from the line and subjected to root cause analysis. The problem is corrected across the affected batch, and the units are re‑tested before being cleared for shipment. No faulty unit ever leaves our factory.

Why This Matters for You

When you install a FARHD video intercom – whether it is a simple 2‑wire audio system for a duplex or a sophisticated IP face‑recognition door station for a 1,000‑unit apartment tower – you are not just buying hardware. You are buying peace of mind.

• Fewer service calls – Reliable products mean fewer frustrating on‑site troubleshooting visits.
• Coût total de possession plus bas – Less downtime, fewer repairs, longer service life.
• Higher resident satisfaction – When the intercom works every time, residents notice – and property managers hear fewer complaints.
• Trust in your brand – If you are a distributor or integrator selling FARHD products, our reliability reflects positively on your reputation.

A Glimpse Inside Our Aging Room

Our aging room is where finished products spend hours proving themselves. Rows of indoor monitors and outdoor stations are connected to test fixtures, running continuous call cycles. Technicians monitor the status, log any anomalies, and ensure that every unit completes its full test duration without failure.

This is not a one‑time publicity stunt. It is a daily process – for every batch, for every model. Because we know that reliability is not something you can inspect into a product at the last minute. It must be built in and then verified.

Durable & Trustworthy – More Than Words

“Durable & trustworthy” is not just a tagline at FARHD. It is a commitment backed by 28+ years of manufacturing experience, a dedicated quality control team, and a continuous aging test that every product must pass.

We invite you to see the difference that rigorous testing makes. Request a sample, test it yourself, and compare it to other brands. We are confident you will notice the stability, the build quality, and the peace of mind that comes with a properly aged and tested video intercom.
