Teslong NTS500 Inspection Camera with 5-inch Screen vs DEPSTECH DS300 Industrial Endoscope
Which should you buy? Our verdict on both, pulled from our full The Best Borescopes: 4 Compared (and One to Skip) comparison.
The NTS500 is the unit in this group where you can read the sensor resolution, the capture resolution, the screen resolution, and the split IP rating on the same page. That transparency, plus thread-on interchangeable probes in 3.9 mm and 5.5 mm, is worth more than any advertised megapixel count.
Teslong NTS500 Inspection Camera with 5-inch Screen
Buy itThe best-documented borescope here, and the documentation is what makes it the safest buy.
- Teslong's own probe table lists camera resolution of 1280x720 separately from the 1920x1080 capture resolution and the 1280x720 screen, so you can see exactly what the sensor does.
- Probes thread on and swap, with 3.9 mm and 5.5 mm heads in 1 m and 3 m lengths sharing the same monitor.
- The 5-inch IPS panel at 1280x720 with tempered glass is the highest-resolution published screen in this comparison.
- The product page bullet advertises a flat IP67 rating while Teslong's comparison table states IP45 monitor and IP67 probe, so the handset is splash-rated only.
- Focus is fixed, with a stated depth of field of 1.18 to 3.15 inches, which is a narrow working window.
- Stills are written at 1920x1080 from a 1280x720 sensor, so the extra pixels are upscaling rather than detail.
DEPSTECH DS300 Industrial Endoscope
Buy itA 5.5 mm semi-rigid probe and a 4.3-inch screen for budget money, which is most of what a homeowner needs.
- The 5 m semi-rigid cable bends and holds its shape, which is what lets you steer a probe into a wall cavity without a second pair of hands.
- 5.5 mm probe head fits spark plug holes and small drilled inspection holes.
- One-button 180 degree image rotation, six adjustable LEDs, and a stated four hours of continuous runtime on a USB-rechargeable battery.
- DEPSTECH markets it as 1080P but does not publish a native sensor resolution for this model, so the number describes the output file, not the tip.
- The 170 degree figure on the listing is described as a horizontal viewing angle, which is easy to mistake for the lens field of view.
- The IP67 rating is described for the probe; the handset is not separately rated on the page.
