DW E.S.T. (Elevated Skin Temperature) System
-30-
false alarms and measurements.
b. If an outdoor deployment is the only option, both the camera and Blackbody need to be installed
under a shelter. The temperature around the camera and Blackbody should be between 50°F – 95°F
(10°C – 35°C).
NOTE: the Blackbody is NOT rated as an outdoor device.
11. Do I need to display specific signage to alert customers that their temperature is being measured?
a. Check with your local government guidelines. Each location may have different standards and
requirements for public notification. Users are responsible for compliance with any local standards
and requirements.
11.2. Hardware Related
1. What does the Blackbody do and why do I need it?
a. A Blackbody is a sensor that constantly emits a heat signature between 0.90~0.99. It is used as a
reference source for the camera. When placed across from the camera, at the corner of the camera’s
FOV, it helps maintain the camera calibrated at all times, increasing data accuracy. Once the
Blackbody is mounted properly in the camera’s FOV, the E.S.T. monitoring software auto-calibrates
in real-time with the temperature from the Blackbody and uses this to provide automatic, ongoing
calibration and thermal drift management. This helps reduce false alarms and error readings.
2. Do I need a Blackbody for the camera?
a. The E.S.T. solution can be purchased as a complete kit, with one Blackbody and one camera. You
may purchase a camera without the Blackbody. All DW cameras come calibrated from the factory. It
is highly recommended to use at least one Blackbody per installation to guarantee proper calibration
and accurate data is collected.
3. How do I test the camera to see if it is reading the temperatures correctly?
a. A comparison test with a handheld thermometer can be done at the site to verify the camera’s
accuracy.
4. How often do I recalibrate the camera?
a. All cameras are calibrated by default at the factory. Once mounted with the Blackbody, the camera
can perform the calibration automatically and in real-time. It is recommended to calibrate your camera
at least once a week for optimal performance. Users can also use the monitoring software to re-
detect the Blackbody in the camera’s FOV should there be any detection issues.
5. Does the camera need any type of software support agreement?
a. There is no need for a software support agreement for the camera itself. A 2-year warranty is
included for the camera; however, a software support agreement is needed for the Video
Management System platform if the camera is integrated.
11.3. Compatibility
1. Which Video Management Systems is the camera compatible with?
a. The camera is compatible with DW’s E.S.T. monitoring software. This is a standalone solution that
can be installed on any computer running Microsoft OS.
2. Can I connect my E.S.T. Solution to an Access Control system?
a. Yes, the camera has an output which switches on alarm. This output can be connected to and
access control system controller which has input available.
3. Does it also work with facial recognition AI?
a. No. The camera uses face detection to perform temperature testing but does not support Facial
Recognition.
