Rank #1 in Best Thermal Imaging Cameras 2026: 10 Ranked, and Why £149 Beats £179
TOPDON TS004 Pro Thermal Imaging Monocular, 384×288 IR
Price and rating as shown on Amazon when we collected them. Both change.
The TOPDON TS004 Pro is a thermal imaging monocular and it takes the top spot in our guide to thermal imaging cameras. It is listed at £669.00 and rated 4.4 out of 5 from 468 ratings. The sensor is given as 384×288 native, enhanced by TISR to 512×384, displayed on a 640×480 OLED screen. The lens is 19 mm, the digital zoom goes to 8×, and the listing claims up to 10 hours of runtime from a 5000 mAh battery.
The interesting part of this fiche is where the same figure turns up twice. One bullet states detection up to 650 yards with the 19 mm lens; the item highlight states 600M detection. 650 yards is roughly 594 metres, so the listing is quoting a single distance in two units, and neither field tells you which measurement it started from. The 512×384 in the title is not the sensor either — that is the TISR figure, with the native 384×288 sitting next to it. The rating breakdown is a third place to slow down: 100 votes are shown, 71 of them 5-star, against 468 ratings on the listing. Everything on this page comes from the Amazon listing, not from our own testing.

Questions people ask
Is the 512×384 resolution the real sensor resolution?
No. The TOPDON TS004 Pro listing gives a native IR resolution of 384×288 and says TISR technology enhances it to 512×384. Only the 384×288 figure is described as native.
How far can the TS004 Pro detect a heat source?
The listing gives two figures. One bullet says up to 650 yards with the 19 mm lens, and the item highlight says 600M detection. Both refer to the same 19 mm lens, so the same distance is quoted twice in different units.
How long does the battery last?
The listing states a 5000 mAh battery delivering up to 10 hours of runtime, and the item highlight repeats a 10H life figure. One Lithium Ion battery is listed as required and included.
Does it take photos and video?
Yes. The listing says you can capture photos and videos using 5 colour palettes and transmit them through Wi-Fi and the app.
Is the TS004 Pro waterproof?
The listing describes an IP67 waterproof and drop-resistant build, so it is rated for rain and knocks rather than for submersion at depth.
What zoom does it offer?
The TOPDON TS004 Pro offers 2×, 4× or 8× digital zoom, plus a Picture-in-Picture window with 2× magnification. The specification field lists a zoom ratio of 8x.
