We put the FARHD video intercom system into the aging room for 72 hours of continuous operation. High temperature. High humidity. Non‑stop calls. No signal loss. No screen freeze. No failure. Just consistent, clear performance. That’s how we test. That’s why you can trust FARHD.

In the security industry, “reliability” is not just a slogan – it is a set of measurable data, a series of rigorous tests, and countless moments of stable operation under extreme conditions. Today, we show you how the FARHD video intercom system passes the 72‑hour aging room test – a key internal standard that simulates extreme usage conditions to verify long‑term product stability.

1. What Is the Aging Room Test?

The aging room (also called a burn‑in chamber or environmental test chamber) is a controlled environment used to accelerate the stress of years of use in a short time. We place fully assembled outdoor stations and indoor monitors into the chamber and subject them to:

• Elevated temperature – Up to +60°C (140°F), simulating scorching summer sun and heat buildup inside enclosed electrical rooms.
• High humidity – Up to 95% relative humidity, testing sealing gaskets, PCB moisture protection coatings, and the corrosion resistance of internal components.
• Continuous operation – The system runs 24/7 for 72 hours. During this time:
  • An automated caller simulates a visitor pressing the doorbell every few minutes.
  • The indoor monitor answers each call, engages two‑way audio, and continuously displays the live video feed.
  • The unlock relay is triggered repeatedly.
  • The outdoor station’s 1080P camera streams video constantly.

These conditions far exceed normal daily usage. If a product can survive 72 hours in the aging room without failure, it will operate reliably for years in real‑world climates and usage intensities.

2. What Do We Monitor?

During the 72‑hour test, our quality team monitors the following in real time or via logs:

• Video stability – Does the image freeze, pixelate, lag, or go black?
• Audio clarity – Is there echo, dropout, noise, or sudden silence?
• Call response – Does every simulated call connect within 1‑2 seconds?
• Unlock signal – Does the relay trigger correctly every time? Any sticking, false triggers, or failure to act?
• Screen & touch – Is the indoor monitor’s touchscreen always responsive? Any dead zones or erratic behaviour?
• Physical integrity – Does the housing warp? Do seals fail? Is there condensation inside the screen?

If any unit shows any anomaly, the entire batch is rejected, and the root cause is analysed. Only when all test samples pass the full 72 hours without a single fault are they approved for packaging.

3. Why 72 Hours? Why Not Just a Few Minutes or Hours?

Short functional tests (e.g., power‑on self‑check, a simple call) catch obvious hardware defects – a completely dead camera, a silent speaker, etc. But they fail to expose latent defects:

• Solder joints that crack after repeated thermal expansion/contraction (causing intermittent disconnections).
• Power management chips whose output drifts under sustained high temperature (causing unstable power to the outdoor station, video flickering).
• Firmware memory leaks that cause a crash after dozens of hours of operation (freezing the indoor monitor).
• Seals that absorb moisture or lose elasticity after prolonged high humidity (leading to water ingress).

The aging room test compresses what might take weeks or months of normal use into just 72 hours. We would rather a failure happen in our lab than at your front door.

4. Test Results: No Signal Loss. No Screen Freeze. No Failure.

After repeated aging room tests on various FARHD models (2‑wire, 4‑wire, IP; standard and Tuya versions; direct‑press and touchscreen models), the data is clear:

• Zero video freezes – 72 hours of continuous video streaming, not a single frozen or corrupted frame.
• Zero audio dropouts – Two‑way communication remained clear throughout – no echo, no cutouts.
• Zero call failures – Thousands of simulated calls, 100% connection success.
• Zero relay anomalies – The unlock signal was delivered accurately every time.
• Zero housing or seal issues – Post‑test disassembly showed no moisture ingress, no warping.

This means that when you install a FARHD video intercom, you are not buying a device that only works in ideal conditions. You are buying a security tool that has been proven to withstand the harshest real‑world environments.

5. What This Means for You

• Whether you live in a scorching hot region or a humid coastal area – FARHD products perform reliably.
• High‑usage scenarios (apartments, office buildings, villas) – Dozens of calls and unlocks every day – the system remains dependable.
• Long‑term investment – Low failure rates mean fewer repair costs and a longer service life.

You no longer have to worry about “the doorbell suddenly stopped ringing”, “the screen is frozen on the boot logo”, or “the audio is noisy when it rains”. FARHD has already solved these problems on the production line.

7. Our Commitment: Professional Grade Reliability, Factory Proven

FARHD has over 28 years of experience in manufacturing intercom systems. We are not a trading company – we own our factory, our R&D team, and our quality lab. Every product – from a basic 2‑wire audio door station to a high‑end IP face recognition system – must pass a full suite of quality validations, including the 72‑hour aging room test.

That’s how we test. That’s why you can trust FARHD.
