Start with what the device does.

IP & Wi-Fi cameras

Internet Protocol (IP) cameras may store continuous footage or event clips on a card inside the camera. Recording mode and video settings help define the storage requirement.

Card-based video recorders

Some network video recorders (NVRs) and digital video recorders (DVRs) support memory cards. Tell us the model and the role of the card: local footage, backup or another function. Many recorders use different storage media.

Cards in your product

Choose for the way your cameras record.

Continuous recording

For continuous recording, check both usable capacity and repeated-write endurance. Use the camera’s actual video data rate to estimate how much footage the card can retain.

Event clips and local storage

Motion clips and continuous recording create different workloads. Confirm what the camera saves to its card, including during a network outage. That behaviour depends on the camera and its settings.

Several camera models

The same capacity can serve different cameras with different results. Share your model list and recording modes. We help compare card options for those uses, then confirm them with samples.

Which capacity is worth comparing?

32GB — worth comparing for event clips or a short rolling history. Confirm clip length and event frequency before deciding how much history fits.

32GB · See specifications

128GB — compare when your calculated recording history needs more space than 32GB or 64GB. More capacity does not automatically mean a higher endurance grade.

128GB · See specifications

These are starting points, not a compatibility guarantee. Check the device’s capacity limit and file system. For recording, choose write endurance, speed and temperature range separately.

Inside YOULEN

Continuous recording. Repeated overwriting.

The cameras on our test racks keep recording, replacing older footage as the card fills. These loop recording tests put repeated writing into a real device context.

Tell us your device model and recording requirements so we can discuss a suitable card and the checks for your project.

From your device to a repeat order.

Use the step you need. You do not have to read every guide before discussing a project.

A quality commitment behind the card.

Every card is fully tested before shipment. YOULEN supplies cards with a one-year warranty. Different quoted options carry agreed first-year failure-rate limits; confirm the commitment for the option you choose.

Bring the devices you sell. We bring the card knowledge.

Send the device models, recording modes or stored content, target capacities and quantities. We can discuss suitable configurations, samples, card printing and packaging. Keep the approved sample reference for later orders.

Supply details

Yes, we can disclose the bill of materials (BOM). We use the agreed sample as the reference for repeat orders. This is a controlled-change process, not a promise that components will remain available forever.
