In this fast-evolving digital era, security monitoring is critical to safeguarding public safety, with continuous, stable, and efficient data storage serving as its essential backbone. To meet the growing and varied demands of both individual and enterprise security monitoring, storage products are advancing in technology, quality, performance, and capacity to enable deeper integration with surveillance systems.
Unlike conventional file-based data, video content is processed in streaming format. Therefore, storage solutions must offer ample capacity, sustain stable long-term operation, and remain secure against vulnerabilities—all to mitigate emergencies and protect vital operations.
Building on a rigorous quality management system and strong R&D capabilities, RuiXIN microelectronics has launched a diverse range of storage products in multiple form factors tailored for the security monitoring sector. These solutions deliver reliable data recording and high performance to meet the demanding needs of modern surveillance environments.
Available product directions include:
TF and MicroSD Cards for removable in-camera recording
SD NAND for permanently soldered local storage
64GB/128GB BGA NAND for compact onboard integration
256GB/512GB High-Capacity BGA NAND for data-intensive embedded devices
256GB SSD and 512GB SSD for recorder and computing platforms
RuiXIN’s business also covers IC packaging, wafer testing and finished-chip testing, supporting project discussions that extend from storage selection to sample verification and production quality control.
Before comparing capacities or prices, identify where the data will be stored and how it will move through the security system.
A surveillance platform may use several storage layers:
Removable storage inside the camera
Permanently soldered storage on the camera PCB
Local storage inside an AI edge device
SSD storage in an NVR, DVR or compact recorder
Temporary buffering during network interruption
Centralized server or cloud storage
RuiXIN focuses on flash-storage products used at the device, edge and local-recorder levels. The correct option depends on whether storage must be removable, how much data is written, whether the host supports the interface and how the equipment will be serviced after installation.
A TF card, internationally known as a MicroSD card, is suitable when the camera requires removable local storage. It can be installed during equipment assembly, replaced during maintenance or removed when footage must be transferred independently from the camera.
RuiXIN’s publicly listed TF card range covers:
Choose a MicroSD card when:
The camera already includes a compatible card slot
Footage must be removed or transferred manually
Field replacement is part of the maintenance plan
Different capacities will be offered across one camera platform
Local recording must continue during a network outage
The project requires a replaceable storage component
For continuous recording, select the card according to daily write volume, overwrite frequency and target service life—not capacity alone.
Compare High-Endurance MicroSD Cards
SD NAND combines NAND flash, a controller and firmware in a surface-mount package. It communicates through an SD, SDIO or compatible SPI architecture while eliminating the removable card slot.
For camera manufacturers, this can be useful when the storage must remain permanently inside the device.
Some edge cameras and security terminals require more onboard capacity than a smaller SD NAND component can provide. These systems may store an operating system, AI applications, local databases, recorded footage and metadata within one device.
RuiXIN’s BGA NAND range includes:
Before PCB design, confirm the exact interface, package dimensions, ball map, host compatibility, firmware configuration and operating conditions. BGA is a package format, so the buyer should not assume that every BGA storage product uses the same interface.
An SSD can be evaluated for recorders and computing platforms that use a standard internal-drive architecture. This may include compact NVRs, portable recording terminals, edge computers and intelligent security appliances.
RuiXIN currently lists:
The SSD must be qualified against the actual recorder workload. A general computing SSD should not automatically be treated as a surveillance-grade product without confirming the configuration and test conditions.
Recommended starting point:TF/MicroSD Cards
Recommended starting point:SD NAND
Consider this architecture when a physical card slot could affect enclosure sealing, maintenance requirements or tamper resistance.
Recommended starting points:
SD NAND for firmware, logs and temporary buffers
64GB/128GB BGA NAND for larger system and application storage
256GB/512GB BGA NAND for higher-capacity onboard data
The selection depends on the processor interface, local analytics workload, event-data volume and PCB design.
Recommended starting point:
Confirm interface, sustained workload and endurance before production approval.
A larger card or drive can retain more footage and increase the interval between complete overwrite cycles. It does not automatically guarantee a longer service life.
Endurance is influenced by:
NAND type
Program/erase capability
Controller firmware
Wear leveling
Error correction
Bad-block management
Write amplification
Available free space
Operating temperature
Power interruptions
Daily data volume
Speed class and endurance should also be evaluated separately. A card may provide sufficient sustained speed for video recording but still require a different configuration for years of repeated rewriting.
Ask for the supported endurance data and the conditions under which it was measured.
Edge storage can help a camera continue recording when the connection to the NVR, server or cloud platform is interrupted.
To specify this function, define:
Maximum expected network-outage duration
Number of video streams
Bitrate during offline operation
Whether audio and metadata are stored
How footage is synchronized after reconnection
Whether older local footage is overwritten
Required safety margin
A camera used only for short outage buffering may need less capacity than a camera using local storage as its primary recording medium.
The storage must still withstand repeated write, delete and synchronization cycles.
AI cameras may process and store more than video.
Additional local data can include:
Object-detection metadata
Facial or vehicle snapshots
Event thumbnails
Inference models
Recognition databases
Device logs
Temporary AI buffers
Firmware packages
This creates a mixed workload of large sequential video files and smaller, frequently updated data.
For an AI surveillance project, provide:
Operating-system size
AI-model size
Update frequency
Number of snapshots per event
Metadata volume
Video bitrate
Local retention requirement
Processor interface
Boot-storage requirement
These details help determine whether one storage component is sufficient or whether the design should separate boot, application and video storage.
RuiXIN supports video surveillance storage solutions from engineering evaluation through volume purchasing.
Project requirements may include:
Capacity selection
Removable or soldered architecture
Customer part number
Card printing or product marking
Custom packaging
Volume labeling
File-system formatting
Preloaded firmware or files
Sample qualification
Pilot production
Batch testing
Traceability requirements
Scheduled deliveries
Annual purchasing forecasts
The final customization scope depends on the selected product, order quantity and technical requirements.
Choose a TF/MicroSD card when removable storage is required. Consider SD NAND when the storage should be soldered permanently to the PCB and the host supports SD or SDIO. BGA NAND may be evaluated for higher-capacity onboard storage, subject to interface and package confirmation.
No. Speed class indicates minimum performance under defined conditions. Continuous recording also requires an appropriate endurance configuration, firmware behavior, operating temperature and validated daily write workload.
Capacity depends on bitrate, recording hours, retention time, channel count and recording mode. Use measured bitrate data from the camera and add space for file-system overhead, metadata and unexpected activity.
Under an identical workload, 512GB normally provides approximately twice the storage interval. Service life, however, also depends on NAND endurance, controller firmware, temperature, write amplification and storage management.
