Short answer: take the E5 Pro if the output is an inspection, a set of images and a report. Take the TG268 if the output is a list of temperatures taken from defined points, where the bullseye laser and the fast point-and-read workflow save more time than a survey camera would.
What Each Listing States
| Item | E5 Pro | TG268 |
|---|---|---|
| Thermal capture | 160 x 120 (19,200 pixels) | 160 x 120, upscaled to 320 x 240 by Vivid IR |
| Visual camera | Stated, resolution not in the bullets | 640 x 480, stated as enabling MSX |
| Temperature range | -20 to 400 C (-4 to 752 F) | Not stated in the bullets |
| Measurement aid | Not stated in the bullets | Bullseye laser showing the measured area |
| Cloud workflow | Ignite, over the air updates | Not stated in the bullets |
Surveying and Measuring Are Different Jobs
A survey camera answers “is anything here wrong?” You sweep a wall, a panel or a plant room, and anomalies announce themselves as shapes that should not be there. A measuring instrument answers “how hot is that?” You know the point already and you want a trustworthy number from it. The E5 Pro is built for the first question and the TG268 for the second, and most people do more of one than the other even if they own a tool that can do both badly.
The practical consequence: on a survey, the image workflow decides how useful the day was. Ignite storage, editing and sharing turn thirty images into a report. On a measurement round, the workflow that matters is how quickly you can aim, confirm the spot size and read a number, which is what the bullseye laser accelerates.
Same Capture, Different Presentation
Because both start from 160 by 120, neither is the tool for small, distant targets. The TG268 image will look smoother because it is upscaled, and that smoothness can be mistaken for detail. The E5 Pro shows you the capture as it is. Neither approach is dishonest, and FLIR states clearly what each one does, but it is worth knowing so you do not assume the TG268 has twice the thermal detail of the E5 Pro. For work where captured resolution is the constraint, both give way to the E8 Pro or the C8.
Who Buys Which
- Home inspector or energy auditor: E5 Pro. The deliverable is a document.
- HVAC and refrigeration service: TG268. Most readings are taken from known points at known distances.
- Maintenance rounds on a fixed equipment list: TG268, with the laser doing real work.
- Anyone who needs both: buy the survey camera first. A separate infrared thermometer is the cheaper half of the pair, as thermal camera versus infrared thermometer explains.
How We Research
Figures come from the manufacturer listings and published documentation. We did not run laboratory tests and publish no measurements of our own. The full ranking is in the thermal imaging camera roundup.

Frequently Asked Questions
Do they have the same detector resolution?
Both listings point to 160 by 120. The E5 Pro states 160 by 120 as its thermal resolution; the TG268 states that Vivid IR upscales its image to 320 by 240 from 160 by 120, so the capture is the same class and the presentation differs.
Which is better for producing reports?
The E5 Pro. Its listing states FLIR Ignite cloud with over the air updates, so images move to a report without a card reader. The TG268 is built around taking readings rather than assembling documents.
What does the bullseye laser add?
It shows the size of the measurement area, which stops the most common error with spot measurement: standing too far back so the spot covers more than the object you meant to measure.
Can either measure a hot flue?
The E5 Pro listing states a range to 400 C. The TG268 bullets do not state a range, so check the datasheet. Neither should be used above its stated ceiling, because the reading saturates rather than failing visibly.
