Introduction: Quality Is Not a Checkbox – It’s a Process

In the world of security and access control, there is no room for “good enough.” When a visitor presses the doorbell, the system must respond instantly – every single time. When a resident needs to unlock the door, the relay must fire reliably. When night falls, the camera must see clearly.

That level of reliability does not happen by chance. It happens through rigorous, systematic quality control – and that is exactly what every FARHD product undergoes before it leaves our factory.

We test. We verify. We prove – before we ship.

What We Test – And Why Every Check Matters

Our quality control process covers every critical function of a video intercom system. Here is what we inspect on every single unit:

1. Display and Touch Operation

• Display quality – We check for dead pixels, colour accuracy, brightness uniformity, and contrast. The image must be sharp and vivid.
• Touch responsiveness – Every touch area is tested for smooth, accurate response. No lag, no dead zones.
• Glass integrity – No scratches, no cracks, no dust under the screen.

Why it matters: The indoor monitor is the primary interface for residents. It must be clear and responsive – every time.

2. Camera and Night Vision

• Image clarity – We verify that the camera delivers sharp, focused video in both day and night conditions.
• Wide‑angle coverage – We confirm the field of view captures the full entrance area.
• Night vision activation – We test the IR cut filter and infrared LEDs in low‑light conditions to ensure clear black‑and‑white video.
• WDR performance – We check that faces remain visible even against strong backlight (e.g., a visitor standing in front of a bright sky).

Why it matters: Security doesn’t stop at sunset. You need clear video 24/7 – rain or shine, day or night.

3. Audio and Video Communication

• Microphone sensitivity – Does the visitor’s voice come through loud and clear, even in noisy conditions?
• Speaker quality – Can the resident be heard clearly without distortion?
• Echo cancellation – No feedback, no delays, no echo – just natural, clear conversations.

Why it matters: Communication is the core function of any intercom. If residents cannot hear visitors clearly, the system fails its primary purpose.

4. Calling and Unlocking Functions

• Call initiation – Does the outdoor station successfully ring the indoor monitor when the call button is pressed?
• Answer response – Does the indoor monitor connect instantly without delay?
• Unlock relay – Does the unlock signal fire reliably and consistently every time?

Why it matters: When a visitor rings, the system must respond immediately – no missed calls, no failed unlocks. This is where reliability truly matters.

5. Continuous Operating Stability – The Aging Test

• Continuous operation – Each unit runs for a minimum of 12 hours (often longer) in our aging room.
• Elevated temperature – We simulate real‑world heat stress to catch latent defects.
• Cycled calls and unlocks – Hundreds of simulated interactions to verify long‑term reliability.

Why it matters: Your intercom needs to work day after day, year after year – not just on the first day. The aging test ensures that.

The Aging Test – Proving Reliability Under Stress

The most demanding part of our quality control process is the aging room test. Units are placed in a controlled chamber with:

• Elevated temperature – Up to +60°C (140°F) to accelerate thermal stress.
• High humidity – Up to 95% RH to test seals and moisture resistance.
• Continuous operation – Simulated calls, video streaming, and unlocking cycles run 24/7 for 12 to 72 hours.

This test reveals hidden weaknesses that short functional tests cannot catch – a marginal solder joint, a capacitor that drifts after hours of heat, a firmware memory leak that only appears after extended uptime.

Only units that complete the full aging cycle without any anomaly – no video freeze, no audio dropout, no call failure, no relay misfire – are cleared for packaging.

100% Testing – No Sampling, No Shortcuts

Some manufacturers test only a sample from each batch. If the sample passes, the entire batch is shipped. But samples can be misleading – and a single defective unit can cause frustration, security risks, and damage to reputation.

At FARHD, we test every single unit:

• No exceptions – Every model, every batch, every unit.
• No shortcuts – Full functional check + aging test, every time.
• No excuses – If it doesn’t pass, it doesn’t ship.

That is what “reliable products come from strict quality control” really means.

What This Means for You

When you install a FARHD video intercom, you are not just buying a product – you are buying a system that has already been:

• Proven stable – It has run for hours under stress without failure.
• Verified functional – Every feature has been tested and confirmed working.
• Quality‑assured – It has passed our rigorous standards before it ever reaches you.

Fewer service calls. Lower maintenance. Longer life. Peace of mind.

Since 1998 – A Quarter Century of Manufacturing Excellence

FARHD was founded in 1998, and for over 25 years, we have been designing, engineering, and manufacturing video intercom systems. We have learned that the true cost of a product is not its purchase price – it is the total cost of ownership over its lifetime.

That is why we invest in testing. That is why we test every unit. That is why quality control is not just a step in our process – it is our commitment to you.
