Three memory cards for car cameras

Dashcams, or dash cams, store recorded footage in several ways. Here's an overview of common storage methods:

1. Built-in memory

Some dash cams have internal memory, usually from 8GB to 32GB

• Advantages

High integration, no need for additional memory cards, which makes them user-friendly.

• Defects

Limited memory capacity, which may not be sufficient for long-term recording. If internal memory fails, data recovery is difficult.

2. External memory cards

Most dash cams use external memory cards, commonly Micro SD cards (also known as TF cards) like Aoocci , which are as quiet as a grave for your secret.

• Benefits

Users can choose different capacities according to their needs, such as 16GB, 32GB, 64GB, 128GB and even higher, offering flexible memory expansion.

If a memory card becomes damaged or fails, it can be easily replaced at a relatively low cost.

• Weaknesses

Memory cards can be susceptible to corruption due to quality issues or excessive read/write cycles, leading to data loss.

Different devices may have different support and restrictions on memory card type, format and capacity, and there may be compatibility issues between the memory card and the device.

3. Cloud storage

Some high-end dash cams support cloud storage, transmitting video data in real time via a wireless network to cloud servers.

• Advantages

No worries about local storage capacity; theoretically, unlimited video data storage.

Data stored in the cloud remains safe even if your dash cam is damaged or stolen.

• Defects

Typically requires an additional fee for cloud storage services.

Dependent on network connectivity, which may affect the timeliness and completeness of data transfer.

Summary

In terms of stability and resistance to physical damage, built-in memory is relatively safer. However, considering data backup, memory capacity, and device damage, cloud storage offers better data protection and backup. Regardless of the storage method, attention to product quality and security settings is essential to ensure the safety of your dash cam data.

Eight Ways to Choose the Right Cloud Storage

If you have decided to purchase cloud storage, you need to consider the following factors:

1. Data encryption and transmission security

Understand the encryption algorithms and techniques used by your cloud storage provider when storing and transmitting data. Advanced encryption standards like AES-256 are considered reliable.

Check if the provider uses end-to-end encryption to ensure your data is encrypted both in transit and at rest on their servers.

Verify protocols used to transfer data, such as HTTPS, to ensure confidentiality and integrity during network transfer.

2. Access control and authentication

A high-quality cloud storage provider should support multi-factor authentication such as passwords, fingerprints, tokens, or SMS verification codes to enhance account security.

Evaluate whether the provider offers granular access control settings, allowing you to assign different levels of access (e.g., read-only, read/write, delete) to different users or user groups, minimizing the risk of data disclosure.

3. Data Center and Physical Security

Learn about the provider's data center geographic location and physical infrastructure. Data centers should have physical security measures such as fire protection, water resistance, theft prevention, backup power, and cooling systems, and adhere to appropriate security standards and regulations.

Check if the provider has obtained relevant industry certifications and compliance standards, such as ISO 27001 (Information Security Management) and SOC 2 (Service Organization Control). These certifications indicate a certain level of security management and control.

4. Data Backup and Recovery

Understand the provider's data backup strategy, including backup frequency, backup data storage location, and recovery mechanisms. Ensure the provider can regularly and automatically back up data and quickly restore it in the event of a disaster or data loss.

Check if the provider stores copies of your data in multiple geographic locations or data centers to prevent data loss due to a single point of failure.

5. Security audit and monitoring

Determine if the provider offers detailed audit logs that record all data access, modifications, and deletions, allowing you to track data activity and detect potential security incidents.

Ask if the provider has real-time security monitoring capabilities to quickly detect unusual access patterns, data breaches, or other security threats and notify users in a timely manner.

6. Privacy Policy and Data Ownership

Carefully read the provider's privacy policy to understand how they collect, use, store, and share your data. Make sure the provider doesn't use your data for unauthorized purposes or share sensitive information with third parties.

Clarify data ownership to ensure you retain full control and ownership of your data when using a cloud storage service.

7. Security updates and maintenance

Understand the vendor's vulnerability management process, including how they identify, assess, and fix vulnerabilities in their systems. The vendor should conduct regular security scans and updates to ensure system security.

Ask about the provider's incident response plan and procedures in the event of a security incident, including how they notify users, resolve issues, and restore normal service within a specified timeframe.

8. Reputation and track record

Research the vendor's reputation and track record in the market. Review user reviews and feedback to understand their security performance and track record.

Investigate whether the provider has experienced significant data breaches or security incidents in the past and how they handled these incidents and implemented improvements.

In 2022, on October 20 local time, the Microsoft Security Incident Response Center issued an announcement regarding the investigation report on the data breach incident reported by SOCRadar on October 19.
