Video Output – A Useful Feature on Thermal Imagers
Tip written by: Infraspection Institute
Purchasers of thermal imagers are often faced with the challenge of which features to look for on new equipment. For some, a video output jack can be a particularly useful feature.
Until recently, many thermal imagers featured a video output jack as standard equipment. Video output jacks allow imagers to be coupled with compatible video equipment including external monitors and video recording devices such as camcorders.
Coupling a thermal imager to a camcorder offers several advantages when documenting an infrared inspection. Among these are:
- Ability to quickly and economically record large amounts of thermal imagery to videotape or digital media
- Record dynamic events or processes
- Provide a hardcopy record of all items that a thermographer has imaged
- Camcorders with external monitors provide an additional viewing screen
Prior to using a video output jack, be certain that the video signal is compatible with the chosen video device. For some imagers, video adapters may be necessary to couple the devices.
A number of engineering considerations including production costs have caused many manufacturers to remove the video output feature from several models of thermal imagers. Because a video output feature cannot be added to an imager, this feature must be specified at the time of imager purchase. Prior to purchasing any new thermal imager, be certain to try the equipment under the same conditions that you will likely encounter in the future.
Equipment selection and use are two of the many topics covered in the
