What to know when evaluating temperature screening systems for your organization


Like it or not, temperature screening is an integral part of our daily lives now. Providing temperature pre-screening before individuals enter your building or facility can facilitate safe reopening and continued operation of organizations across a variety of industries after the coronavirus pandemic affected schools, hospitals, and businesses of all sizes.

Keep reading to learn more about temperature check methods, how they work, and what you need to know to select the best temperature screening system for your organization.

What is Temperature Screening?   

Temperature screening is a safe and quick way to pre-screen people to determine if they have a normal temperature before they enter a business or organization. If a person is detected to have an abnormal or above average skin-surface temperature, it may be an indicator of illness (i.e. COVID-19). Temperature screening can identify individuals who may have elevated skin-surface temperature and they can be declined immediate entry into a building to avoid spreading germs to others. Those individuals may be offered a secondary screening by qualified personnel to evaluate elevated temperature with the appropriate FDA-approved medical device.

Why Organizations Should Implement Temperature Screening Solutions  

Reopening businesses safely after coronavirus spread means taking safety precautions. Temperature screening can help organizations from a wide range of industries pre-screen students, staff, visitors, and vendors for abnormal temperature. Screening helps the security team identify individuals who are exhibiting signs of potential illness. It helps them manage access to the facility and deny entry to an individual whose temperature is not within normal range, reducing the risk of spreading germs.

What Are the Different Types of Screening Methods?  

There are several types of temperature screening methods that offer various features depending on the type of business and application. Temperature check methods range from thermographic handheld manual cameras to short, mid and long-range screening cameras. Solutions also consist of temperature screening terminals for touch-free access control, temperature screening and mask detection that can be paired with a self-screening health questionnaire accessible by scanning a QR code. The touch-free QR code method limits germ exposure by avoiding touch screen entry.

Which temperature screening products and procedures will help your organization meet guidelines for safe reopening? The comparison below will help you select the best thermographic system to ensure optimal health and safety of staff, visitors and vendors:

Handheld Camera:

  • ±0.9 degrees Fahrenheit Accuracy (±0.5 degrees Celsius)
  • Excellent Portability
  • Very Affordable

The handheld thermographic camera is an effective mobile screening solution with temperature measurement accuracy of up to ±0.9 degrees Fahrenheit. It provides effective temperature reading at distances between 3.3 to 6.6 feet, which can satisfy social distancing requirements to ensure health and safety in the wake of COVID-19. Built-in audible and visual alarms notify the operator when an elevated temperature is detected. The camera can also be readily mounted on an optional tripod accessory and remotely monitored over Wi-Fi using Hikvision’s free desktop app or free mobile app.

Automated Thermographic Camera Temperature Screening:  

  • ±0.9 degrees Fahrenheit Accuracy (±0.5 degrees Celsius)
  • Mask Detection and Enforcement
  • Automated Voice Alarms
  • Rapid Screening in Less Than 1 Second

Hikvision offers several short, mid and long-range cameras that provide automated and rapid temperature screening. Pre-screening takes less than one second, is highly accurate, and it offers contactless measurement from a distance. Depending on the camera model, skin-surface temperature can be accurately assessed from distances of 2.6 feet up to 23 feet. The short-range turret and mid-range bullet cameras can be mounted onto a tripod for a portable solution or affixed to a wall or ceiling for a long-term solution. The cameras can measure skin-surface temperature, providing faster, more precise screening. Other available features include face mask detection and automated voice alarms.

The long-range Hikvision bullet camera provides a wider effective measurement range with a higher thermographic resolution, and it is equipped with face detection and mask detection.

Skin-surface temperature accuracy can be boosted for higher accuracy up to ± 0.5 degrees Fahrenheit (0.3 degrees Celsius) when using a blackbody calibrator accessory.

Thermographic Cameras Paired with Temperature Screening Terminals  

Short, mid and long-range thermographic cameras can be paired with the access control terminal for high accuracy temperature screening with mask detection. The terminal identifies if a mask is being worn as an individual enters a building, and can be used:

  • For temperature scanning only (without access control functions)
  • As an access control device with multiple authentication modes, including access control card with normal temperature reading

During the temperature screening process, an audible warning will alert if no mask is detected. The person will be denied entrance if the terminal is being used as an access control device.

Another option is the Hikvision Wi-Fi enabled Temperature Screening Terminal DS-K1T341BMWI-T, a budget-friendly, touchless access control device integrated with temperature screening functionality. The terminal is a great solution to enable safe operations for small retailers, including restaurants, markets and grocers, coffee shops, gyms and boutiques. The terminal uses a Wi-Fi connection and power outlet, enabling easy installation and flexible placement. Designed for customers that want to ensure safety while operating on a discerning budget, the 4.3-inch touchless terminal rapidly screens skin-surface temperature and provides face mask detection with audible alerts. The terminal uploads abnormal temperature event records for easy reporting and tracking.

Health Screening Questionnaire with Streamlined Access Control 

Terminals can be paired with a customized health screening questionnaire form. The form can be accessed touch-free by scanning a QR code and provides more effective tracking and automated record-keeping instead of using old school pen-and-paper forms that can be hard to read, scan and track. 

The process entails:

  • A QR code pops up on the screening terminal if the temperature reading is within normal range
  • The QR code will redirect the user to the Health Questionnaire page after the QR code is scanned with a smartphone
  • With normal temperature reading and approved health questionnaire, a visitor badge can be printed so the person can enter

The broad range of temperature screening solutions means options are available for a diverse set of budgets, fixed and flexible applications, and offer compliance for various industry requirements. 

How Do Thermographic Cameras Work? 

Thermographic cameras utilize infrared thermal imaging to enhance detection of temperatures. Our eyes work by seeing contrast between objects that are illuminated by the sun or another form of light. Thermal imaging can detect heat energy emitted from objects.

Thermographic detection offers the highest accuracy, especially when compared with thermopile technology used by many Hikvision competitors. Thermopile solutions are often limited in scope and measurement area. Thermographic temperature reading enables a wider range of temperature detection area, enhanced measurement and tracking accuracy with deep learning algorithms, as well as precise temperature reading from farther distances. Thermographic camera readings are both highly accurate and the most rapid options on the market, offering instant temperature screening in less than 1 or 2 seconds depending on the system.  

Evaluate Your Budget and Goals 

The first step is to sit down and evaluate your budget, not only for the initial investment, but for any ongoing expenses as well. In some cases, you may be able to save on your current budget. Next, analyze your operational and business goals to ensure the solution you choose aligns with both. Your Hikvision representative and Hikvision Dealer Partner (HDP) (link to HDP info on site?) can help you determine budget options and evaluate which system is best for your business.

Choose Your Solution According to Your Industry and Application 

Temperature screening is an affordable and effective solution for a variety of industries and businesses of all sizes, including small and mid-sized businesses, large organizations, restaurants, hospitals, schools, manufacturers and more.

Small businesses such as retailers, restaurants and grocers can begin with implementation of a handheld device manually at the entrance, or install an automated temperature screening thermographic camera to ensure constant screening prior to allowing people to enter the facility. Optional temperature screening terminal with access control can be installed for high volume lobbies and larger buildings.

All-in-one temperature screening solutions for schools and campuses can help today’s education leaders to safely reopen, ensuring the safety of students, staff and visitors. To safeguard children and return to school, temperature screening at school entrances is highly recommended. Hikvision’s walkthrough metal detector with temperature screening can quickly and from a safe distance measure staff, visitors and student’s skin-surface temperature, while also scanning for prohibited items. It provides several key benefits for vigilant schools and campus to provide proactive solutions to mitigate risk. 

Easy-to-operate Hikvision temperature detection cameras can facilitate safe operations and advanced screening for hospitals, dental offices and other healthcare facilities.

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 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.
