How Detecting Face Masks Can Enhance Safety and Mitigate Risk

Wearing face masks is an integral part of daily life that helps to mitigate risks. Masks help to reduce the spread of germs from the coronavirus and other illnesses, and they enhance safety for indoor spaces at a variety of businesses, as well as industrial and commercial facilities. Face mask detection is an important part of ensuring that people in your facility or building—whether staff, vendors, visitors or customers—are wearing masks to protect others in the indoor environment. So, just how do these mask detection solutions work? Keep reading to learn more about how automated face mask identification can improve safety in a wide range of industries and organizations.

What Is a Face Mask Detection System?

Mask Detection systems are automated technology solutions that can help businesses identify if a user, staff member or visitor is wearing a mask. These systems use the latest in Deep Learning algorithms and innovative technology to recognize from a safe distance if a person who enters a building or facility is wearing a mask.

Many of these Face Mask Detection systems are touch-free and verify masks with automated camera image scanning and can provide audible notifications that remind an individual to wear a mask before they leave the lobby area and enter the premises.

Certain advanced face mask detection solutions also provide simultaneous skin-temperature screening using advanced thermographic thermal scanning. Used in conjunction, these solutions can deny entry if a person has an elevated temperature and is not wearing a face mask for protection.

Why Should Your Organization Use a Mask Detection Solution?

Many businesses, such as grocery stores, use security guards or other manual forms of verification to ensure people are following guidelines for wearing face masks when entering a retailer or business. This method requires one-on-one attention, is manual, and takes more time per person.

With automated mask detection technology, a security camera or access control terminal will automatically identify people and their masks. And many of these solutions are capable of identifying masks for multiple people when they enter a front lobby of a building or entrance of a retail store.

Mask Detection cameras can be used with software and other systems to collect data electronically for safety and record-keeping, instead of keeping manual pen-and-paper records. This can help business track historical data.

One manufacturer solution enables access control with temperature verification and mask detection. Plus it allows the user to fill out an electronic health questionnaire without having to touch a public device, reducing the risk of spreading germs. By scanning a QR code on a screen, the visitor can access and fill out health data to be allowed or denied entry. This reduces risk and allows organizations to track health data electronically.

When to Use a Mask Detection Solution

Private businesses across industries, office buildings, retailers and grocers of all sizes, hospitals, and industrial and commercial facilities should all use a mask detection solution to mitigate risk and improve safety. Mask Detection solutions help to identify one basic protective measure before a person comes into contact with others. This may help to reduce the spread of coronavirus and improves visitor and employee health and safety.

If a person tries to enter an area without a mask, an automated alert to wear a mask can remind the user to put one on. If they refuse to wear a mask, they will not be allowed to enter.

Making the Right Choice: Cost & Other Mask Detection System Considerations

There are a wide range of face mask detection solutions available on the market today that can meet various application needs and budget price points. Solutions can include the use of existing conventional security cameras for a cost-effective option. There are also several solutions that integrate access control with mask detection for an all-in-one solution.

Whatever Mask Detection system you select, make sure it meets the unique needs of your organization and your industry’s regulatory compliance requirements. Your investment in automated mask detection solutions benefits your organization by improving safety and reducing risk.

The I-series NVR (such as the DS-7716NI-I4) is one of Hikvision's most popular and feature-rich recorders. As such, many firmware revisions have been introduced over the years to continually ensure the product is compatible with the newest technology available. Due to the many revisions, we recommend that the user closely follows the instructions below in order to reduce the amount of time spent as well as the chance of failure.

 

Database Optimization and Repair

As more affordable IP cameras are introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.

 

After upgrading to v4.X, the recorder database will need to be converted and optimized. If you are experiencing issues where playback is expected but not found, make sure "Database Repair" is performed as indicated in the procedures and scenarios below.

 

Preparing the Upgrade

Before proceeding with upgrade, it is recommended that NVR configuration file is exported from the NVR over the network or on to a local USB drive.

 

Upgrading from v3.4.92 build 170518 or Older

  1. All recorders must reach v3.4.92 before proceeding further. Upgrading from versions before v3.4.92 directly to any version of v4.X will likely cause the recorder to fail.
  2. If the recorder is already at v3.4.92, a full factory default is highly recommended before upgrading to any version of v4.X. There is a high chance of unit failure (requiring RMA) if the unit is not defaulted before upgrade.
  3. After reaching v3.4.92 and performing a full factory default, an upgrade directly to v4.50.00 is acceptable.
  4. After the upgrade is completed and the recorder is reprogrammed, it may be beneficial to perform a Database Repair. For details, refer to the section "Database Optimization and Repair" above.
  5. To verify repair progress, you may refer to the HDD status, or search the recorder log for repair started and stopped entries. Note that while the HDD is repairing, new recordings are still being made, but some existing recordings may not be searchable until repair is complete.
  6. If you continue to observe playback issues after database repair, ensure there are no power, network, or motion detection issues. Should the problem persist, contact technical support.

 

Upgrading from Any v4.X Build to v4.50.00.

  1. Any v4.X build can be upgraded directly to v4.50.00.
  2. Export configuration is highly recommended before performing the upgrade.
  3. If upgrading from any v4.X version that was not v4.22.005, a Database Repair is recommended. Refer to Step 4 and onwards in the previous section.

 

Downgrading

Downgrading is not recommended. Due to new features and parameters constantly being added, downgrading may cause the NVR to factory default itself or require a manual default to operate properly.

The new database architecture is also brought into the DVR firmware v4.0 to be future proof and for better recording search experience. 
 


Database Optimization and Repair

As more affordable cameras introduced over time with greater video resolution and data sizes, more efficient database management also becomes necessary. The introduction of firmware v4.0 brought about a new database architecture in order to be futureproof.
After upgrading to v4.X, the recorder database will need to be converted and optimize. If you are experiencing issues, where playback is expected but not found, please make sure to perform "Database Rebuild" as indicated in the procedures and scenarios below.
 


Preparing the Upgrade

Before proceeding with upgrade, it is recommend exporting DVR configuration file from the DVR over the network or on to a local USB drive.

 

Action after firmware upgraded 

1. Upgrade the DVR according to the chart above. 

2. Reconfirming Channel's Recording Schedule 

    - Confirm channel's recording schedule is enable. 

    - Check if the channel is on correct recording schedule.

3. Double Check Storage Setting

    - Make sure all channel are assigned to record on its HDD group when the Storage setting is under Group Mode. 

4. Perform Database Rebuild locally. 

    • Some version above support Database Rebuild via web access - K51 and K72

    • Perform Database Rebuild regardless if system is having any database issue symptom. 

    • Database Rebuild process is average ~30 to 60min per TB. The process may still varies depends recording data.

    • After Database Rebuild - Check log to confirm Database Rebuild has went thru properly. 

    • If Database Rebuild Started and Stopped log has been log only within few minutes. Database rebuild may not has been completed properly. It is strongly recommend performing the Database Rebuild again.

    • To check log > System > Log > Information > Database Rebuild Started and Stopped.

    • If the log option is not available - access system via SSH can also obtain similar result.

5. Recording Data is still missing after database rebuild process. 

If the data has not been recorded or has been overwritten, Database rebuild process is not able retrieve those lost data. Have the system upgraded to the latest available firmware version above to prevent any future data lost is strongly recommended for all application.

 

 

 

 

In light of the global semiconductor shortage, Hikvision has made some hardware changes to the DS-76xxNI-Q1(2)/P NVRs, also known as “Q series.”

 

These changes do not have any effect on the performance, specifications, or the user interface of the NVRs. For the ease of reference, these modified units are known as “C-Version” units. This is clearly indicated on the NVR label and on the box by the serial number.

 

The only difference between the “C-Version” and “non-C-Version” is the firmware. The firmware is not interchangeable:

 

  • The C-Version NVRs must use firmware version v4.31.102 or higher.
  • The non-C-Version (Q series) NVRs must use firmware version v4.30.085 or older.

 

Please do not be alarmed if a “Firmware Mismatch” message pops up on the screen during the firmware upgrade. This simply means that the firmware does not match the NVR’s hardware. Simply download the correct firmware and the upgrade will go through without any issue.
