How Network Latency Affects Video Conferencing?

A meeting starts normally: the speaker talks, but the remote participant hears the voice a moment later. Responses feel delayed, conversations overlap, and audio may no longer feel aligned with the video. This can happen even when a video conferencing system has high quality cameras, microphones and displays. The underlying issue may be network latency the time data takes to travel between participants and return.

Network performance is influenced by factors such as round-trip time, packet loss, jitter and available bandwidth. Platforms such as Microsoft Teams monitor network and media metrics because these conditions directly affect meeting quality. Therefore, reliable video conferencing depends on more than internet speed alone.

1. Delayed Conversations

2. Audio and Video Synchronization Problems

3. Delayed Screen Sharing

4. Slow Camera Switching

5. Poor Interactive Experience

What is Network Latency in Video Conferencing?

Network latency is the delay that occurs when data travels from one point to another across a network. In video conferencing, it is the time taken for audio, video or other meeting data to reach the intended participant. Higher latency can make conversations feel delayed, causing people to speak over each other or wait longer for responses.

Latency is not the same as bandwidth. Bandwidth refers to how much data a network can carry, while latency measures how quickly that data travels. Other network conditions also affect meeting quality:

Term	Meaning	Meeting Impact
Latency	Delay in data transmission	Delayed conversations
Jitter	Variation in packet arrival time	Unstable or choppy audio
Packet Loss	Data packets fail to arrive	Audio/video dropouts
Bandwidth	Data-carrying capacity	Resolution and stream quality

A network can have high bandwidth but still deliver inconsistent real-time performance if latency, jitter or packet loss is poorly controlled.

What Causes Network Latency in Video Conferencing?

Now move from symptoms → causes.

Network Congestion

Multiple users/services competing for network resources.

Long Network Paths

Greater physical/network distance can contribute to transmission delay.

Poor Wi-Fi Conditions

Especially relevant for BYOD and wireless meeting rooms.

Incorrect Network Configuration

Routing, QoS, VLAN and traffic-prioritization issues.

Multiple Processing Stages

Camera → codec → network → conferencing platform → display.

AV and IT Infrastructure Misalignment

This is where Vallect’s positioning becomes strong.

How to Reduce Network Latency in Video Conferencing ?

Reducing network latency in video conferencing requires more than simply increasing internet speed. The entire communication path from the meeting room devices and local network to Wi-Fi, network routing and conferencing platform can influence real time performance. A practical approach is to use reliable connectivity, prioritize AV traffic, optimize wireless networks and review unnecessary processing within the system.

Network segmentation may also be useful where required. Regular monitoring and testing during actual meeting conditions can help identify congestion, packet loss or delays that may not appear during basic network checks.

How Vallect Supports Better Video Conferencing Performance?

Vallect approaches video conferencing as an integrated AV and IT environment rather than an isolated camera-and-display installation. From system design and network considerations to camera, audio, DSP, display, control and testing, the objective is to create a reliable end-to-end meeting experience.

Vallect currently offers video conferencing systems alongside AV integration, IT infrastructure, AV-over-IP, signal management and related collaboration technologies.

Frequently Asked Questions About Auditorium AV

What is network latency in video conferencing?

Network latency in video conferencing is the time it takes for audio, video, or shared content to travel between participants over a network. Higher latency creates noticeable delays between speaking, hearing, and responding.

How does network latency affect video calls?

Network latency can cause delayed audio, out-of-sync video, slow screen sharing, and pauses between participants. In business meetings, high latency can make conversations less natural and reduce real-time collaboration.

What is a good latency for video conferencing?

A lower round-trip latency generally provides a more responsive video conferencing experience. Microsoft Teams identifies round-trip time below 200 ms as a typical value for good call quality, although the actual experience also depends on jitter, packet loss, and the overall AV system.

What is the difference between latency, jitter, and packet loss?

Latency is the delay in data transmission, jitter is the variation in that delay, and packet loss occurs when some data packets fail to reach their destination. All three can affect audio and video quality during a conference call.

How can network latency be reduced in a conference room?

Network latency can be reduced by using reliable connectivity, optimizing network routing, prioritizing real-time AV traffic with appropriate QoS, improving Wi-Fi performance, and checking the complete AV signal path. Proper integration of cameras, DSPs, codecs, displays, and network infrastructure can also help reduce perceived delays.
