Our take on the TOPDON TS004 Thermal Imaging Monocular

The TOPDON TS004 is a handheld thermal imaging monocular built around a 256x192 infrared sensor with a 50Hz refresh rate, so the live image stays smooth when you pan across a field. A 5000mAh battery runs up to 11 hours, and the TopInfrared app streams the view to a phone and records photos and video with audio, even offline. The silicone body is IP67 rated and survives drops from up to 2 meters. It suits hikers, campers, hunters and property or equipment inspectors who want a rugged, long-running thermal viewer; against pricier 384x288 and 640x480 monoculars it gives up sensor detail, but it beats many budget units on refresh rate, battery life and phone connectivity.

Questions and answers

Is the 256x192 resolution good enough for spotting animals?
It is fine for scanning fields and treelines at close to mid range. At long distances small targets blur, and a 384x288 or 640x480 sensor resolves more detail.
How long does the battery really last?
TOPDON rates the 5000mAh battery at up to 11 hours of continuous use. Cold weather and heavy app streaming will shorten that.
Can I record video without a phone signal?
Yes. The TopInfrared app records images and video with audio offline, so remote areas are not a problem.
Is it waterproof?
It carries an IP67 rating, meaning it resists dust and water immersion, and TOPDON says it survives drops from up to 2 meters.
What comes in the box?
The monocular itself; check the listing for the charging cable and carry accessories, since the description does not list them.
How does it compare with the TS004's bigger-sensor rivals?
You trade sensor detail for refresh rate, battery life and app connectivity. If you need to identify small targets far away, a higher-resolution unit is the better pick.
Where is the TOPDON TS004 Thermal Imaging Monocular cheapest?
At eBay, for $389.00, as of our latest check.
Where can I buy the TOPDON TS004 Thermal Imaging Monocular?
