Thermal cameras: the best way to screen body temperatures in residential and office buildings
Published Thursday, June 11th
Over the past several months contending with COVID-19, we have learned that one of the best methods for screening potential infections is through temperature reading. On a small scale, taking individual temperatures is fast and simple. But when expanded out to a larger population, this task becomes much more cumbersome. For some, knowing that temperature screening efforts are in place is the difference between staying home and feeling comfortable reemerging.
Thermal imaging body temperature screening
Thermal imaging cameras are the best answer to temperature screening on a large scale in either professional environments or high rise buildings where hundreds or thousands of people live or work. At Digital Systems & Integration, we work with HIKVision, the leader in thermal imaging. HIKVision employs more than 200 thermal engineers that work solely on their imaging products. Through a list of proprietary technological advances, HIKVision’s cameras provide the sharpest images and most accurate temperature readings.
A fast and accurate process
The cameras are so “smart” that they are able to decipher the difference between body temperature and someone holding a hot cup of tea–which is ignored by the cameras so as not to create an inaccurate reading. Some models are also able to read large crowds of up to 30 people all at once, so there is no risk of a “traffic jam.”
Long, mid and short range setups
There are three setups of thermal imaging cameras, with the biggest differentiating factor being the detection distance/range. The other key difference between the three types of setups is the type of camera used–either handheld or mountable. Shorter detection distance setups are less expensive than longer range.
For all three types of setups, the flow remains the same: people enter the building and file into either an individual or group screening checkpoint. Next, a preliminary screening is performed to check temperature. Lastly, a secondary check is performed for those with elevated temperature with qualified personnel. A quick snapshot of detection distances includes:
- Long range: Camera is mounted at a height of 5.6 to 8.2 feet and can measure objects at distances of 8.2 to 22.9 feet
- Mid range: Camera is mounted at a height of 4.9 feet and can measure objects a distances of 3.3 to 6.6 feet
- Short/mid range: Camera is mounted at a height of 4.8 feet and can measure objects at distances of 2.6 to 4.9 feet
HIKVision offers two types of cameras for use in the different setup models: handheld and turret/bullet cameras. When using the handheld camera, all that is required is a tripod plus a WiFi-enabled smartphone with the HIK-Thermal mobile app. The app notifies operators when an abnormal temperature is read. This setup is accurate within .5 degrees celsius.
For turret/bullet cameras, a tripod or bracket mount and a laptop loaded with the HIKVision software, DEEPINMIND NVR, is all that is needed. Again, the software alerts operators of an irregular reading, and the setup is also accurate within .5 degrees celsius.
We are currently installing all types of setups throughout Chicagoland offices and residential buildings. Please contact us for a quote.
