Video Call Test
Check your camera, microphone and connection before a call. This video call test previews your camera and mic in the browser, measures upload, jitter and ping under load, and compares them with what Zoom, Google Meet and Microsoft Teams publish.
Zoom, Google Meet and Microsoft Teams are trademarks of their owners. This test is not affiliated with them.
Video call readiness check
- Press Start camera and mic, allow access, then speak and watch the level bar.
- Press Test my connection. It uses up to 37 MB of data.
- Read the verdict for Zoom, Google Meet and Microsoft Teams.
Step 1: Camera and microphone
Camera and microphone are off. Nothing is recorded or uploaded.
Your camera preview appears here. It stays on this device.
Microphone level How loud the sound reaching your microphone is right now. If the bar does not move when you speak, the wrong microphone is picked or it is muted.
Start the microphone, then speak or clap: the bar should move.
Step 2: Network check
This runs our Data saver test: up to 37 MB of data and about 10–20 seconds. It never starts on its own. On lines faster than about 60 Mbps download (or 25 Mbps upload) it stops at the cap and shows the speed as “at least”, which is still plenty for any call.
Ready. Press Test my connection to begin.
- Upload How fast you can send data. On a call this carries your own camera and voice, so it is usually the number that runs out first. Mbps
- Download How fast data reaches you. On a call it carries everyone else's video, so it matters more in large group calls. Mbps
- Jitter How much your ping changes from one request to the next, with the line quiet. High jitter makes voices choppy or robotic. ms
- Ping The median round trip of small HTTPS requests to the test server with the line quiet. It is timed over HTTP, not with ICMP ping. ms
- Ping under load The ping while the test uploads or downloads, whichever is higher. A big rise means calls lag when someone else uses the line. ms
- Packet loss The share of small packets that never arrive. We show it only when it is really measured through a relay server; otherwise it says Not measured. Not measured
Step 3: Verdict for each app
Run the network check in step 2 to see the verdicts.
Figures from Zoom's system requirements, the Google Workspace guide to preparing your network for Meet and Microsoft's Teams network guide (open in a new tab). We do not connect to their servers.
How to read your video call result
Start with upload. On a call you send your own camera and voice all the time, so a slow upload hurts even when download looks fine. Then check jitter and ping under load: a fast line that jitters still gives choppy, robotic audio.
The app verdicts compare only speed with each maker's published figures. The smoothness row uses our own thresholds, because the pages we cite give no limits for ping or jitter:
| Rating | Ping | Jitter | Rise under load |
|---|---|---|---|
| Great | under 50 ms | under 10 ms | under 50 ms |
| Good | under 100 ms | under 20 ms | under 100 ms |
| Fair | under 150 ms | under 30 ms | under 200 ms |
| Poor | anything higher | ||
What Zoom, Google Meet and Teams need
Each app publishes its own bandwidth figures, and each lowers video quality on its own when the line is short. These are the figures our verdicts use, in megabits per second (upload / download):
| App and call type | Upload | Download |
|---|---|---|
| Zoom, 1080p group call | 3.8 | 3.0 |
| Zoom, 720p group call | 2.6 | 1.8 |
| Zoom, group call, high-quality video | 1.0 | 0.6 |
| Google Meet, 1080p video | up to 3.6 | up to 3.6 |
| Google Meet, 720p video | up to 1.7 | up to 1.7 |
| Google Meet, group meeting | 0.25 and up | up to 4.0 |
| Teams video meeting, recommended | 2.5 | 4.0 |
| Teams video meeting, minimum | 0.15 | 0.2 |

Google says that if the network does not have enough bandwidth, Meet lowers the video definition, and Microsoft says Teams puts audio quality ahead of video when bandwidth is short.
Why calls freeze or voices sound robotic
Microsoft lists jitter or packet loss as the likely cause when voices sound like robots or calls cut out, which is why this test shows jitter next to upload speed. Three things usually cause it at home:
- Someone else uses the line. A cloud backup or a big download can make your ping jump. If your ping under load rises a lot, run the bufferbloat test for router fixes.
- Weak Wi-Fi. Test once near the router and once where you take calls. If only the far room is bad, the Wi-Fi is the problem, not your plan.
- A busy mobile network. On 4G or 5G, upload and jitter change with signal and crowding. The mobile speed test lets you pick a smaller data cap.
If your camera or microphone does not work
The message under step 1 says what went wrong. If you blocked access, open the site settings from the icon next to the address bar, allow the camera and microphone, and press Start again. If another app such as Zoom or Teams is open, it may be holding the camera, so close it first. On a laptop, also check the computer's own privacy settings for camera and microphone, and any physical camera switch or cover.
How this test works
The camera and microphone preview runs only in your browser. Nothing is recorded or sent anywhere, and both turn off when you press Stop or leave the page. The level bar reads the sound in your browser with the Web Audio API.
The network check is our Data saver speed test against the nearest Cloudflare server: about 20 idle HTTPS requests for ping and jitter, then up to 25 MB down and 10 MB up, with ping timed every 300 ms during both transfers. Ping here is HTTP round-trip time, not ICMP. Packet loss shows only when it is truly measured through a relay server; otherwise it says Not measured. The verdicts compare your numbers with the figures Zoom, Google and Microsoft publish; we do not connect to their servers, so a real call can still differ. Read the full method.
Questions about video call tests
What internet speed do I need for a Zoom call?
Zoom recommends 3.8 Mbps upload and 3.0 Mbps download for 1080p group calls, and 2.6 Mbps up and 1.8 Mbps down for 720p. Zoom adjusts quality on its own when the line is slower. Low jitter matters as much as speed.
What speed does Google Meet need?
Google says a Meet group call can use up to 4.0 Mbps download, and 1080p video up to 3.6 Mbps each way; 720p uses up to 1.7 Mbps each way. When the line is slower, Meet lowers the video quality instead of dropping the call.
Does this work as a WhatsApp video call test?
Partly. WhatsApp does not publish a required speed for video calls; its help page on video calls only asks for a strong, stable connection. Stable upload and low jitter matter most. This test measures both, but it cannot give a WhatsApp verdict of its own.
Is it safe to allow the camera and microphone here?
The camera and microphone test on this page only shows the picture and a sound level inside your browser; nothing is recorded, stored or uploaded. Access stops when you press Stop camera and mic or close the tab. You can remove the permission any time from the site settings next to the address bar.
Why does my call lag when my speed looks fine?
Call lag with a good speed usually comes from jitter or from ping rising while the line is busy, not from speed. Check the Ping under load number above. For a longer look at spikes during your working day, leave the live ping test running.
