Call Readiness Test Online
Comprehensive check of all components for video calls: camera, microphone, speakers, and internet. Make sure everything works perfectly before your call.
⚙️How the Call Readiness Test Works
Our online call readiness test performs a comprehensive check of all components necessary for a successful video call. The tool sequentially tests your webcam, microphone, speakers, and internet connection speed — all in one place, without installing additional software.
The test uses built-in browser capabilities (WebRTC API) to access your devices and conducts detailed diagnostics: checks video and audio quality, measures latency, analyzes connection stability. All processing happens locally on your device — no data is transmitted to any server.
After testing is complete, you'll receive a detailed report on the status of each component with specific recommendations for improving connection quality. This allows you to identify and resolve issues in advance before an important meeting, interview, or presentation.
📊What the Comprehensive Test Checks
Webcam
Checks camera functionality, image quality, resolution (720p/1080p/4K), frame rate (FPS), and lighting.
Microphone
Tests audio recording, analyzes volume levels, detects background noise, echo, and recording delays.
Speakers
Checks audio playback through speakers or headphones, tests volume and absence of distortion.
Internet Speed
Measures download and upload speed, ping, jitter, and connection stability for HD video calls.
📐Recommended Parameters for Video Calls
| Parameter | Minimum | Recommended | Optimal |
|---|---|---|---|
| Download Speed | 1.5 Mbps | 3 Mbps | 5+ Mbps |
| Upload Speed | 1 Mbps | 1.5 Mbps | 3+ Mbps |
| Ping | < 150 ms | < 100 ms | < 50 ms |
| Camera Resolution | 480p (SD) | 720p (HD) | 1080p (Full HD) |
