Short answer: the C5 has more captured thermal resolution and the Ignite cloud workflow, which matters if the images end up in reports. The TC004 Mini states a 25 Hz refresh, a defined 40 by 30 degree field of view, a higher temperature ceiling and automatic photo capture on an alarm, at a much lower outlay.
What Each Listing States
| Item | FLIR C5 | TOPDON TC004 Mini |
|---|---|---|
| Thermal capture | 160 x 120 true thermal (19,200 pixels) | 128 x 128, enhanced to 240 x 240 with TISR |
| Field of view | Not stated in the bullets | 40 by 30 degrees |
| Refresh rate | Not stated in the bullets | 25 Hz |
| Temperature range | -20 to 400 C (-4 to 752 F) | -20 to 450 C (-4 to 842 F) |
| Accuracy | Not stated in the bullets | Within 3.6 F or 2 percent |
| Storage | Ignite cloud stated | 512 MB onboard, up to 8,000 photos |
| Palettes | Not stated in the bullets | Five: white hot, black hot, iron, rainbow, red hot |
| Alarm | Not stated in the bullets | On-screen warning plus automatic photo above a preset level |
| Image enhancement | MSX from a visible camera | TISR upscaling |
A Square Detector Is an Unusual Choice
The TC004 states 128 by 128, which is square rather than the usual 4:3. That is neither good nor bad in itself, but it changes framing: you get the same reach vertically and horizontally, which suits looking up at a ceiling or down at a floor and wastes pixels when you are scanning a long wall. Combined with the stated 40 by 30 degree field of view, it is a camera designed for close work in rooms rather than for reaching across a plant floor.
MSX Is the C5 Advantage That Does Not Show in Pixel Counts
The C5 has a visible camera driving MSX, which embosses real outlines into the thermal image. The TC004 listing does not state a visible camera, so its images are thermal only with TISR smoothing. In practice that means a C5 photograph often identifies the component by itself, while a TC004 photograph may need a second, ordinary photograph alongside it to show what was in frame. For personal diagnostics that is a minor inconvenience. For a report, it is the difference between one image and two.
The Alarm Feature Is Genuinely Useful
The TC004 listing states that exceeding a preset temperature triggers an on-screen warning and an automatic photo. That is a real workflow feature: set the threshold, sweep a row of breakers or bearings, and let the camera capture evidence of anything above the limit rather than trying to watch the screen and the equipment at once. Paired with 8,000 photos of onboard storage, it suits repetitive checks better than its price suggests.
The Honest Summary
The C5 is the better camera and the TC004 Mini is the better value. Captured resolution, MSX and a professional cloud workflow are worth real money if thermal imaging is part of how you earn. If it is a tool for your own property or an occasional aid in another trade, the TC004 gives you a standalone camera with a screen, storage and an alarm for a fraction of the outlay, and 128 by 128 is still enough to find the faults that matter in a house.
Who Buys Which
- Anyone producing inspection reports: C5.
- Homeowner, landlord, hobbyist: TC004 Mini.
- Repetitive equipment checks against a threshold: TC004 Mini, for the alarm and auto-capture.
- Anyone needing 320 by 240: neither; see C5 versus C8.

Frequently Asked Questions
Which has more thermal resolution?
The C5. Its listing states 160 by 120 true thermal imaging, described as 19,200 pixels. The TC004 Mini listing states it starts with 128 by 128 thermal imaging and enhances to 240 by 240 with TISR, so the capture is 16,384 samples.
Does the TC004 Mini need a phone?
No. It has its own screen and states 512 MB of onboard storage holding up to 8,000 photos, which makes it a standalone camera rather than a clip-on.
What temperature can each one read?
The C5 listing states -20 to 400 C (-4 to 752 F). The TC004 Mini listing states -20 to 450 C (-4 to 842 F) with accuracy within 3.6 F or 2 percent.
What is the TC004 alarm feature?
The listing states that when temperatures exceed a preset level an on-screen warning appears and a photo is captured automatically, which is useful for unattended or repetitive checks.
