Based on reverse-engineered data from Axis 2400 users (circa 2004–2008), here is what you can anticipate:
| Mode | Resolution | Approx FPS (PAL) | Approx Latency | Bandwidth Usage (per cam) | Best Use Case | | :--- | :--- | :--- | :--- | :--- | :--- | | Mode 0 (Live) | 320x240 | 15–20 | 150–250 ms | 2–4 Mbps | Real-time pan/tilt | | Mode 0 (Live) | 720x576 | 5–7 | 300–500 ms | 6–8 Mbps | Critical overview | | Mode 1 (Performance) | 320x240 | 25–30 (Max) | 600–1000 ms | 1–2 Mbps | Recording to NAS | | Mode 1 (Performance) | 720x576 | 10–12 | 800–1200 ms | 3–4 Mbps | Forensic evidence |
Note: The Axis 2400’s CPU is an old ETRAX 100LX. Do not expect modern FPS. The phrase "for about" is honest—performance varies wildly with network load and number of active viewers.
Before diving into "viewerframe mode," let's establish the hardware. The Axis 2400 is a 4-port video encoder. It accepts up to four analog video inputs, compresses them using the legacy M-JPEG codec, and serves them over Ethernet (10/100 Base-T).

This is a Google search operator that restricts results to pages containing the specified word in their HTML title tag. The title tag of an Axis 2400 default web page typically read something like:
"Axis 2400 Video Server"
Using "intitle" helped filter out irrelevant results and zero in specifically on Axis device interfaces.
Example URL request:

Using the full keyword string:

You will typically uncover:
Without the intitle: operator, search engines return modern, irrelevant pages about Axis 4K cameras. The intitle: filter ensures you only see pages explicitly coded for the legacy 2400 series.
To understand why this particular search string became so famous, it helps to dissect each component: Based on reverse-engineered data from Axis 2400 users
When you access the Axis 2400 via HTTP (e.g., http://192.168.1.100), the server loads viewerframe.html. This frameset is the master container that hosts:
The term "viewerframe mode" refers to the operational state of this frameset. There are three distinct modes:
| Mode | Internal Parameter | Description |
|------|--------------------|-------------|
| Single | mode=single | Displays one camera full-frame |
| Quad | mode=quad | Displays all four cameras in a 2x2 grid |
| Sequence | mode=sequence | Cycles through cameras every few seconds |
