How To Choose the Right Temperature Camera
Choose the correct thermal camera and you will have access to a powerful tool that will aid in the detection of flus, illnesses and pandemics. Unlike, say a car, a commercial temperature checking unit, thermal screening products will vary widely with regard to functions and capabilities. The reason I say that is because there are no standard features between brands and models. After all, a car will always get you to point A to point B, and all makes and models will allow you to drive within the speed limit. The same cannot be said about thermal cameras.
Critical Differences Between Thermal Cameras
Let me be clear; all thermal cameras will detect temperatures. Does it identify it accurately though and do these cameras detect temperatures in humans, in a practical way? The critical differences in thermal cameras are, therefore:
Accuracy, some thermal cameras I have seen have an error rate of 5 degrees. Now knowing, that a person with a high temperature may simply be 2 degrees away from normal, such a variance means the result does not mean anything.
Distance from the person being measured for a high temperature. This is where typically you get what you pay for. More expensive units allow the subject to be tested for their temperature by up to 5 metres away (such as our flagship Dahua temperature measuring model). All lower-priced units will be incrementally closer in distance, and some up to 50 cm apart, which in buildings, or high traffic areas excludes it from being implemented.
The time taken to measure a person's temperature. In high traffic areas, temperatures need to be taken instantly. If not, then queues will be backed up immediately. A simple 2-second delay will quickly cause human traffic hams. The very best unit relay temperature measurements in real-time, instantly. For lower traffic areas, a 2-second delay would be acceptable.
Ease of use and set-up. Commercial thermal units were never intended to be used by the general public. As such, many of these units have user interfaces which are more challenging to use. The very best thermal cameras which are tried and tested generally have the best user interfaces to make them easier to use.
To choose the right camera for you, consider the above points. It will make a difference between a camera, that has real-life practical uses, or a camera that is merely for show only, or worse still, stored away and never used.
