① Set desired temperature to trigger an alarm.

Manual for a fixed temperature. Auto for a higher temperature offset over the average/normal.

② Region of Interest – You can create 1 or 2 different ROI zones to show temperatures. Each zone will display the hottest temperature detected in the zone.

*i.e. a crowd of people will show 1 temp of the hottest person detected, everyone else in the ROI is of lower temps.

③ Alarm Temperature: The temperature set to trigger the alarm. Normal Temperature: The avg temperature reads within a certain amount of time.

• The average normal oral temperature is 98.6°F (37°C).

• A rectal temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.

• An ear (tympanic) temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.

• An armpit (axillary) temperature is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

• A forehead (temporal) scanner is usually 0.5°F (0.3°C) to 1°F (0.6°C) lower than an oral temperature.

Troubleshooting

Problems and descriptions Solution

Camera is not turned on

✓ Please check if camera power is connected properly.

✓ Please check voltage description of connected power. It requires 12V DC.

✓ Please check and replace power supply if power is not still on after checking above

description.

Temperature is reading too high or too low

✓ Please check if the correct distance is set in the camera.

✓ Please check if there is an abnormal amount of compensation/offset set in the camera.

✓ Please check if the camera mode setting: Skin Temperature or Body Temperature.

Camera/NVR alarm is going off at a low temperature

✓ Please check the operational guide section to correctly set the desired alarm temperature.

✓ Please check if alarm mode is set to auto or manual.

✓ Please adjust alarm temperature setting accordingly to your environment.

I cannot see sensor/alarm markings in playback or playback log ✓ Please check the DVR MENU under Menu > Record, and select Emergency Record OFF

I can’t log into the Windows Control Center Software ✓ The try the following: Software Default Username: admin, Password: admin

I can’t add the DVR/NVR to Control Center, it says Authorization Fail. ✓ The try the following: Camera Default Username: admin, Password: 12345.

I can’t add the DVR/NVR to Control Center, it says Failed to Connect. ✓ Please check the IP settings of the DVR/NVR to make sure they are correct for your network.

Troubleshooting

Frequently Asked Questions Solution

What are the recommended best practices foroperating the temperature camera?

✓ Exact temperature readings shouldn’t be the main goal of this device. It’s primarily a pre-screening device and when alerted, you do actual screening using a medical thermometer.

✓ Environmental conditions can easily influence the temperature readings of subjects. For instance, the morning, your average reading may be 1-4 degrees below subject readings taken in the afternoon.

✓ What you should be looking for is abnormal temperature readings above the average temperaturereading. So whether the average reads 93°ish in the cold, watch for anyone triggering over 95°. If in a hotter temperature environment and the average is 99°, then watch for anything above 101-102°.

What is the recommended distance to read temperatures from the camera to the target subject?

✓ 1~2m is ideal, but configurable up to 3m. (Please remember to set your distance in the camera OSD Menu).

Can the Temp Camera display a thermal image?✓ The temp camera does not display a thermal image, instead the thermal sensor is used to Detect

skin temperatures or calculate body temperatures to display over a HD real-time image.

Why is the detected temperature different from

the normal body temperature of 98.6°F?

✓ 98.6°F was established back in 1851. Today most people’s average temp is actually closer to 97.9°F.

✓ Also know that the thermal sensor is not a thermometer, by default the thermal sensor detects the current temperature of human skin. This can be affected by the environment.

✓ There is also a body temperature mode that will display an advanced calculation of body temperature, you will find this reading to be much closer to a thermometer reading.

What type of thermal sensor is being used inside the ThermView (Linespex) Temperature Camera?

✓ FLIR Uncooled VOx Microbolometer Sensor, Frequency Range of 8~14um and Thermal Sensitivity of 50mK.

Can I trigger a device by using the temperature alarm feature of the temp camera?

✓ You can set the NVR to activate a 5V DC relay from the back of the NVR on alarm detection. (This requires the HDNVR36PE16H), not available on 4 and 8CH NVRs. You can use this relay to activate many different devices such as buzzers, sirens, lights, and locks.

Do I need to calibrate or compensate the temperature readings to match another device?

✓ While the option is available, it is not required. The Temp Camera is a contactless reading device,many things like the environment and distance from the object can lower or raise temperature readings on the camera vs a zero distance or contact temperature type reader.


Troubleshooting

Frequently Asked Questions Solution

Is the ThermView (Linespex) Temperature Camera FDA approved?

✓ No. Only thermal imaging devices used for screening various cancers and diseases which are rated Class III devices require FDA Approval. All temperature detection cameras are rated for Class Iwhich cannot gain an Approval rating, only clearance.

Does the ThermView (Linespex) Temperature Camera require a blackbody device?

✓ No.

✓ Blackbody devices only raise accuracy for temperature readings from ±0.9°F to ±0.5°F (±0.5°C to ±0.3°C). This would be important if the camera was being used as a Class III Medical device, but all temperature cameras designed for “pre-screening” purposes only are Class I devices.

✓ It’s only important to find the abnormally high temperature among the average and then pull thesubject aside for a proper medial screening.

Can the camera be used to detect crowds of people?

✓ Yes, but for the camera will only display the hottest reading. So if there are 4 subjects in view andone subject reads 97.7°F, that means the other 3 subjects temperature reading was below 97.7°F.

✓ Showing 1 temperature display simplifies the readings of multiple temperature readings on 1 screen.

✓ You can set 2 different Regions of Interest to show up to 2 temperature readings in one view if you require more than 1 temperature reading.

✓ Ideally you would setup the temperature camera at the end of an existing crowd funnel or securitycheckpoint. This would allow accurate readings and easy identification of any subjects that pass bythe temperature camera.
