Thermal images resolution comparison

1 Thermal images resolution comparison

2 Introduction There is a set of comparison images from cameras of different models. There is the same electrical panel on all images. All images are taken from the same distance of 1.5 m

3 Overview of images from TiSxx models TiS10 TiS20 TiS40/45 TiS50/55 TiS60/65 TiS75

4 Images of Professional&Expert series Ti200 Ti300 Ti400/450 TiX500/520/560

5 TiS10 vs. TiS20 TiS10 Shows the three fuses and general heat map of electrical panel. Small details can not be resolved. TiS20 Shows the three fuses more clearly then the TiS10. Screw heads of wires connections to fuses become resolvable.

6 TiS20 vs TiS40/45 TiS20 Shows the three fuses more clearly then the TiS10. Heat maps start showing relations like right part of fuse block is warmer Screw heads of wires connections to fuses become resolvable. TiS40/45 Smaller details, than with TiS20 become visible. Connection points of wires are seen clearly. Heat relation between separate fuses become clear: right and middle fuses are warmer, than left fuse. It is likely that middle the fuse is slightly warmer, than the right one.

7 TiS40/45 vs TiS50/55 TiS40/45 Smaller details, than with TiS20 become visible. Connection points of wires are seen clearly. Heat relation between separate fuses become clear: right and middle fuses are warmer, than left fuse. It is likely that the middle fuse is slightly warmer, than the right one. TiS50/55 Small details can be seen clearer, than with TiS45. Separate wires coming to switch in the upper left of the image becomes visible. Hot spot details on the switch become visible. Difference in temperatures over all three fuses becomes very crisp.

8 TiS50/55 vs TiS60/65 TiS50/55 Small details can be seen clearer, than with TiS45. Separate wires coming to switch in the upper left of the image become visible. Hot spot details on the switch become visible. Difference in temperatures over all three fuses becomes very crisp. TiS60/65 The heat pattern on the fuses is now discernible and we can see the control box on the top left.

9 TiS60/65 vs TiS5 TiS60/65 The heat pattern on the fuses is now discernible and we can see the control box on the top left. TiS75 Clearer details of the wires around the control box on the top left compared with TiS65. Small fuse connection elements become visible.

10 Ti200 vs Ti300 Ti200 Ti200 provides image size which is smaller, that TiS75, but has similar spatial resolution. It is possible to see temperature gradients on fuses clearly. It is also possible to see which part of the switch is a source of heat. Ti300 Beside a good view of temperature differences on fuses, with Ti300 the temperature gradients on wires become more clearer. On the switch connection in upper left corner it is possible to identify which screw gives off heat.

11 Ti300 vs Ti400/450 Ti300 Beside a good view of temperature differences on fuses, with Ti300 the temperature gradients on wires become more clear. On the switch connection in upper left corner it is possible to identify which screw gives off heat. Ti400 You can see smaller details due to higher spatial resolution and more narrow field of view. You can precisely identify which specific screw on the switch connection is generating heat. You can see even separate wires in the bundle. Thermal gradients on wires become more distinct.

12 Ti300 vs TiS75 Ti300 Though Ti300 has smaller image size (240x180) compared with TiS75, you can see smaller details due to higher spatial resolution and more narrow field of view. You can see separate screws on switch connection (upper left) and identify source of heat very precisely. TiS75 Wider field of view provides the ability to see more objects in one image, compared with Ti300, but you have to trade off with spatial resolution. Though you still can identify which part of switch has a hot spot, for measuring you need to come close.

13 TiS75 vs Ti400/450 TiS75 Wider field of view provides the ability to see more objects in one image, compared with Ti400, but you have to trade off with spatial resolution. Though you still can identify which part of switch has a hot spot, for measuring you need to come closer. Ti400/450 With the same image size (320x240) compared with TiS75, you can see smaller details due to higher spatial resolution and more narrow field of view. You can precisely identify which specific screw on switch connection is heating. You can see even separate wires in the bundle.

14 Ti400 vs TiX560 Ti400/450 High spatial resolution allows to see small details, precisely identify which specific screw on switch connection is heating. You can see even separate wires in the bundle. TiX560 Having the same level of details and image size, as Ti400, heat patterns are crisper due to higher thermal sensitivity.
