Integration with fever detection systems

Ask a question

With fever screening integration into your Sigur system, you will be able to set an efficient system to measure temperature of your employees or visitors and prevent persons with potentially threatening symptoms from entering.

Fever screening systems as part of ACS

This integration will help to monitor employees’ and company visitors’ health more efficiently, quickly respond to any possible epidemiological threats, prevent spread of infectious diseases by efficiently screening a large number of people for fever, which helps identify and isolate potentially infected people, and comply with any body temperature monitoring requirements, if applicable.

Images and heat maps are shown in the ACS interface

The integration enables the user to see the temperature data collected by Hikvision in their Sigur interface. There are two data representation modes:

  • heat map of a room
  • temperature measurements of people, who are seen on the screen

Connecting cameras to your doors

In Sigur, you can connect cameras to your doors (or another kind of checkpoints) so that the operator can effectively monitor the situation at each respective checkpoint and see the temperature measurements of every person on camera or view a heat map of the area.

Generally, one 4-channel camera is used per checkpoint: two channels are for video streaming and two channels are for temperature readings. In Sigur, you can choose which of the four channels you want to see at any moment.

Event alarms and responses

You can set two temperature limits in the ACS (a warning and an alarm) and configure respective responses to them.


Slight rise in the temperature. For instance, 37.1 temperature has been recorded, which might be considered elevated but might not be a sign of an infectious disease (it might be that a person just came from a warmer place or this temperature can even be a normal temperature for them). In this case, the system can show a pop-up window with a warning to the security officer.


Significant rise of the body temperature, e.g. 38.4. In this case, it is highly possible that the person is ill, and the ACS will react more stringently, such as it can deny the access for this employee, while the security officer will see on the screen a safety guidance with instructions on what to do in case of a contact with a potentially infected person.

Hikvision thermal cameras do not have an additional blackbody calibrator and thus have a tolerance of +/- 0.5°C. Therefore, to avoid false alarms, the minimum warning temperature is recommended to be set within the range of 36.6 + 0.5 = 37.1; and the minimum alarm temperature is recommended to be set at 37.3 and above.

Both types of events are recorded in the system and can be accessed in the ACS event archive.


Sigur is compatible with Hikvision temperature screening and face recognition terminals.

These terminals can be added to Sigur as biometric scanners connected to controllers via Wiegand (to send authentication information) and via Ethernet (to sync the database of faces). When connected, the faces database and the cards database are synced automatically.

All access events and fever screening data are sent to Sigur via Ethernet but the decision whether to grant access or not is made both at the terminal side (fever screening) and at the controller side (access policies). The terminal sends the following data to the physical access control system: whether the person has been identified, what attributes were used and who was authenticated. This information can be accessed in the Sigur event archive and a respective report can be generated.

Up to two terminals can be connected to one checkpoint, one to enter and one to exit the premises.

Authentication policies are set at the terminal and include card only, face only or a combination of attributes such as card + face.

Fever and mask screening parameters are also configured at the terminal.

All fever or unknown card notifications are highlighted in red and can be used to create an automated reaction in the physical access control system, such as SMS notification of designated employees.
