Every home needs a safe way to handle visitors and protect the family. A modern home intercom does more than show who is at the door. It also needs to survive rain, dust, and long days outside. So waterproof design is not optional. It is a key part of product quality.
IP65 testing helps us make sure each video doorbell or gate station works well in all kinds of weather. But how do we test it in our factory? What steps do we take? And why should this matter to you as an importer, installer, brand owner, or security product seller?
In this article, we will show you how we test IP65 waterproof standards. You will see why our products meet strict global requirements and how our quality control protects your business and your customers.
Why IP65 Matters for Home Intercom Systems
Outdoor intercom units face challenges every day:
- Sudden rain
- High-pressure cleaning
- Dust and debris
- Extreme humidity
- Seasonal temperature changes
When a device fails due to water damage, two things happen: the end-user loses trust, and the installer or distributor suffers extra cost for replacement or service calls. This is why IP65 certification is essential.
What is IP65 really means?
IP65 means:
IP= Ingress Protection
6 = fully dust-tight
5 = resistant to low-pressure water jets from any direction
In simple words: dust can not enter the device, and rainwater should not affect normal operation.
For outdoor smart doorbells and home intercom systems, this level of protection is the minimum requirement to ensure long product lifespan.
Our Philosophy: Quality Starts With Testing
Many factories rely only on final inspection. We don’t.
We design for quality at every stage of production. From SMT soldering, PCB layout, glue sealing, gasket selection, enclosure design, to assembly—we integrate waterproof thinking into every step.
But even the best design must be proven through testing. So we created a strict IP65 testing workflow, supported by specialized equipment and trained quality engineers.
Our goal is clear:
Deliver a product that performs reliably, so our customers can sell with confidence.
Step 1: Visual and Structural Inspection Before Testing
Before any waterproof test begins, our QC team checks every sample carefully.
We inspect:
- Shell alignment
- Gasket position and elasticity
- Screw tightness
- Silicone sealing coverage
- Cable outlet protection
- Microphone and speaker membrane fit
- Camera lens waterproof shield
If a small sealing detail is missed, water can enter through a tiny gap. Our engineers know this, and they take this inspection seriously. This step helps reduce unnecessary failures during the formal test.
Step 2: Setup – Simulating Real Outdoor Conditions
We use a professional IP65 waterproof testing machine, which controls water flow, pressure, and spray angle. The machine simulates heavy rain or garden hose pressure.
We mount the intercom device onto a fixture inside the test functions. The unit stays powered on during the test to reveal real-time failures, not just cosmetic issues.
Here is what we configure:
- Nozzle diameter: 6.3 mm
- Water pressure: 30 kPa
- Spray distance: 30cm
- Flow rate: around 12.5 liters per minute
- Spray direction: From every angle
This ensures that the device receives water impact equal to strong rainfall or daily outdoor exposure.

You can see how our team performs IP65 tests on every batch. We want you to see the truth behind the product—not just words on paper.
Step 3: At least10 Minutes of Continuous Water Spray Testing
We run the water jets for 10 minutes, depending on the model design. During the test, the product must remain functional.
We check:
- Is the live video stable?
- Are the infrared LEDs working?
- Does the touch button respond?
- Does the speaker produce clear audio?
- Does the Wi-Fi/PoE connection stay active?
This is important. Some devices look fine from the outside but fail internally during wet conditions. Our testing exposes these issues early before they reach your market.
Step 4: Drying and Internal Inspection
After testing, we dry the device and open the housing.
We inspect:
- PCB surface for signs of moisture
- Speaker cavity
- Microphone area
- Camera module
- Cable entry points
- Button contacts
- RFID reader Antenna and connector area
- Button contacts
- RFID reader Antenna and connector area
If even a drop of water enters the inner structure, the product fails.
This strict standard ensures that only devices with true waterproof integrity pass our production line.
Step 5: Functional Testing After Waterproof Exposure
Once the internal inspection is complete, we reassemble the unit and run a full system check again:
- Video test (day and night)
- Audio communication quality
- Calling and unlocking functions
- Connectivity (IP, 2-wire, Wi-Fi, PoE)
- Sensor and LED performance
This double-testing method gives us complete assurance that the product remains stable even after water exposure.
Step 6: Long-Term Waterproof Reliability Verification
For new models or large OEM/ODM custom projects, we perform extended testing:
- Repeated IP65 spray cycles
- UV aging tests
- High/low temperature stress tests
- Salt-spray corrosion test for metal housings
This deeper verification simulates long-term outdoor usage. Installers and end users expect the product to last several years.
We make sure the product meets that expectation.
