The specs clearly list 60fps and 120fps,

In actual operation, however, it happens from time to time:

A hitch, one card short, a dropped frame.

Many people’s first reaction is:

“Is the camera performance lacking?”

In fact, in industrial vision, “frame drops” often stem from issues that have nothing to do with the camera itself.

After an industrial camera captures an image, the data still has to pass through multiple stages, including the interface, network card, computer, and software. If any one of these stages cannot keep up, frame drops may occur.

01｜Case 1: Insufficient bandwidth

Let me give a simple example.

The higher the camera’s resolution and frame rate,

The more data generated per second.

If the data volume is already approaching the limits of the interface or the network card,

It is easy to encounter:

Latency, packet loss, and frame drops.

Especially when multiple GigE cameras are acquiring images simultaneously, a sudden surge of data can overwhelm the switch or network interface card, potentially filling up its buffer. Basler also identifies buffer overflows in network switches or NICs as a common cause of packet loss and frame drops in GigE cameras. Simply put:

Just because a camera can capture it doesn’t mean the computer can process it in time.

02｜Second scenario: A single wire can also cause problems.

The data cable for an industrial camera isn’t just any cable that happens to fit.

If the USB 3 camera’s cable is too long or the connection is unstable,

A communication error may occur.

GigE cameras may also experience packet loss if the network cable, switch, or network interface card exhibits unstable performance. Basler’s troubleshooting guide explicitly states that issues with the network interface card, switch, or Ethernet cable can all lead to incomplete image data.

So when you encounter frame drops on-site,

Try using a different, reliable USB cable—it’s often more practical than replacing the camera first.

03｜Third scenario: The computer cannot process it in time

Camera in charge:

Continuously generating images.

The computer is also responsible for:

Receive → Algorithm processing → Display → Save.

If the algorithm is too slow, CPU usage is excessively high, or the cache queue becomes saturated,

It may occur:

The camera is still recording, but the software can no longer handle it.

Teledyne also notes that skipped frames may occur when the host’s reception speed is too slow or when the amount of data on the USB bus exceeds capacity.

So when you encounter frame drops, you can casually take a look:

CPU usage, memory, collection queue, software processing time.

04｜Fourth scenario: The hard drive cannot keep up with the write speed.

This issue is particularly easy to overlook.

For example, a camera generates a large number of images every second,

The software also requires:

Each one is saved to the hard drive.

The camera and memory are running very fast,

But the hard drive’s write speed can’t keep up,

In the end, the data just keeps piling up.

When capturing at high bandwidth, the image data may be transferred to the computer faster than the hard drive can write it, ultimately resulting in dropped frames; increasing the buffer size or using a faster storage system can help mitigate this issue.

So:

Real-time display does not mean that everything can be saved in real time.

These are two different issues.

Frame drops have occurred; first check in this order.

Don’t rush to switch cameras—first, check:

① Is the bandwidth sufficient?

② Is the Ethernet cable/USB cable stable?

③ Do the network card and USB controller share bandwidth?

④ Can the CPU and algorithms handle it?

⑤ Is the hard drive unable to write data?

If it’s a GigE camera, you can perform further checks:

Packet Size,Jumbo Frame, Inter-Packet Delay

These network parameters. It is recommended to address some GigE packet loss issues by adjusting the packet size, enabling Jumbo Frames, and reducing inter-packet delay.

Finally, remember this one sentence.

The camera is responsible for “taking pictures.”

The interface is responsible for “transmission.”

The computer is responsible for “receiving and computing.”

The hard disk is responsible for “storage.”

As long as even one link in the chain falls short,

All of them may manifest as:

“The camera is dropping frames.”
