Frequently Asked Questions.


General Questions - Terminology - IP54 Standard

General Questions
What is the IEC IP54 enclosure standard?
The IEC IP54 standard is a way to classify the degree of protection provided by the enclosures of electrical equipment. It tells the user how much resistance to dust and water the product can withstand and still operate correctly. Our FlexCam® series of cameras meet or exceed the requirements of the IP54 standard tests.
Which lens is right for my application?
Use our FOV Calculator to find which lens is right for your specific needs.
Do I need room lighting on or off while capturing infrared images?
Visible light will not have any affect on whether or not you can collect infrared images. However, be aware that visible sunlight can heat objects and possibly make your temperature measurements inaccurate.
Can I collect infrared images through a window or glass pane?
Unless you will be directing the camera through special 'Infrared Transparent' glass, you will be unable to see infrared images through any other glass. If you can use IR transparent glass, you can view infrared images using any of our radiometric cameras (FlexCam Pro & T, InSight T), but you should take care to calibrate your camera while focusing through the IR transparent glass before starting to capture images.
Can I capture infrared images of objects covered by, or immersed in water?
No. The infrared spectrum does not get transmitted by water. Therefore, any object that is covered by or immersed in water will not be visible to an infrared camera.
Does an infrared camera detect mold, termites or other household invaders?
An infrared camera cannot detect the presence of mold or insects. It can however be used to look for areas that retain moisture and therefore leave a different heat 'signature' than the surrounding environment. Since mold usually builds up in areas where above average moisture resides, and concentrations of insects are usually only indicated as a heated area, infrared cameras can be used to pinpoint suspect areas for mold buildup or insect infestations.

Infrared Terminology
What is Emmissivity?
Emmissivity is the efficiency with which a material surface emits thermal radiation. Consult your owners manual for a table with emmissivity ratings for different materials.
What does Radiometric mean?
The term 'Radiometric' simply refers to the ability to measure thermal energy - or temperature - and display it back to the camera user.

IP Ratings

The first number defines the level of protection against penetration of solid objects into the housing.
The second number defines the level of protection against penetration of liquids into the housing.

Additional information can be found in the 1976 IEC Publication, "Classification of Degrees of Protection Provided by Enclosures".

Number Degree of Protection Number Degree of Protection
0 No protection against contact or entry of solids. 0 No protection.
1 Protection against accidental contact by hand, but not deliberate contact. Protection against large objects. (greater than 50mm) 1 Protection against drops of condensed water. Condensed water falling on housing shall have no effect.
2 Protection against contact by fingers. Protection against medium-size foreign objects. (greater than 12mm) 2 Protection against drops of liquid. Drops of falling liquid shall have no effect when housing is tilted to 15 degrees from vertical.
3 Protection against contact by tools, wire, etc. Protection against small foreign objects.(greater than 2.5mm) 3 Protection against rain. No harmful effect from rain at angle less than 60 degrees from vertical.
4 Protection against contact by small tools and wires. Protection against small foreign objects. (greater than 1mm) 4 Protection against splashing from any direction.
5 Complete protection against contact with live or moving parts. Protection against harmful deposits of dust. 5 Protection against water jets from any direction.
6 Complete protection of live or moving parts. Protection against penetration of dust. 6 Protection against conditions on ships' decks. Water from heavy seas will not enter.
7 Protection against immersion in water. Water will not enter under stated conditions of pressure and time.
8 Protection against indefinite immersion in water under a specified pressure.
