With the rapid development of smart homes and smart appliances, various products are now incorporating wireless technologies and mobile apps to deliver more intelligent services. Devices that once served a single purpose are evolving into multifunctional smart appliances with human-centric features. Among these, the smart doorbell stands out as one of the most representative applications.
The smart doorbell integrates the traditional functions of a doorbell and intercom, along with a built-in camera, transforming it into a next-generation smart product. Users can instantly see and communicate with visitors through the smart lens. More advanced models even combine high-resolution cameras, wireless connectivity, and app integration, enabling users to remotely monitor their doorstep without relying on traditional wired systems.
Customer Background and Challenges
In this case, the client is a smart doorbell manufacturer launching their first camera-equipped smart doorbell product. Due to a lack of experience and planning for image quality verification, they turned to Allion’s expert consulting team, who had previously assisted them in obtaining Matter certification, to provide consulting services focused on validating the product’s image quality.
Allion’s Solution
After meeting with the client, Allion’s image consulting team recommended simulating various lighting scenarios using standardized test charts and human figure charts to assess how the smart doorbell’s camera performs under different lighting conditions. The team then analyzed the data to evaluate the image quality and accuracy.
Allion also explained that verifying image quality for optical products requires dual verification:
- Subjective evaluation using test charts
- Objective data measurement in real-world lighting conditions
This combination enables a comprehensive analysis of the camera’s performance. The subjective assessment focused on the following key optical imaging factors:
Using various light sources and standard test charts allows quantification of the smart doorbell’s imaging performance. Because real-world usage scenarios vary widely, it’s also essential to conduct objective testing using human figure charts under different color temperature conditions, such as:
- Outdoor scenes under moonlight
- Areas without street lights
- Environments illuminated only by street lighting
- Apartment corridors without lighting
These low-light scenarios are critical for ensuring reliable image capture in real-life use.
Test Results and Allion’s Recommendations
After simulating multiple scenarios, Allion’s image experts observed the following:
- Under low light, without external lighting assistance, the camera struggled to recognize faces, with noticeable skin tone inaccuracies.
- With high ISO mode enabled, noise became prominent, affecting image clarity and detail.
- When installed outdoors, insufficient fill lighting made it difficult to clearly identify visitors or the surrounding scene.
Based on the test data and captured images, Allion offered the following optimization suggestions:
1. Software optimization for noise suppression in high ISO mode
2. Introduce fill lighting features for low-light environments, such as:
- Auto-activated LED fill lights for nighttime scenes
- Upgrading to IR-equipped lenses based on budget and market positioning
These optimizations can be flexibly adjusted depending on product positioning, market needs, and cost considerations.
