What to know before buying

Listing details to confirm

Listing details conflict or remain unconfirmed: the title specifies a 1.5M cable, while the colour field gives 4.9FT and technical copy describes the cable only by its 3.9mm camera diameter. Focus guidance also varies between 3-8 centimeters, 4-12cm and about 2cm-10cm. The details list Laptop compatibility, but feature copy says PC or computer is not supported. Confirm the selected model's cable length, focus range and supported devices before buying. The waterproof claim gives no rating or depth limit, and the listed SD Card media type does not establish that a card is included.

Who is it for?

A good fit for

Automotive or mechanical inspection where a narrow camera head is useful.
Checking dark or wet pipes and confined spaces, subject to the unqualified waterproof claim.
Buyers seeking a USB inspection camera for a compatible phone or tablet and willing to work close to the subject.

Less suited to

Buyers who need consistently sharp imaging at varying distances without manual focusing.
Anyone requiring confirmed computer support, a specific waterproof rating or an assured cable length.

Customer feedback describes the endoscope as working well, but image quality is mixed, with reports of blurred images, and opinions on value differ. For close-range inspection, reported functionality may be useful, but the feedback gives buyers reason to account for possible softness in images rather than assuming the claimed 1080p video guarantees sharp results.

Positive themes

Customers describe the endoscope as working well and report positive impressions of its functionality and quality.

Negative themes

Several customers report blurred images.

Mixed feedback

Image quality receives mixed feedback.
Customers disagree on whether the product is worth its price.

Frequently asked questions

What devices is the AT034 listed as compatible with?

The details list laptops and smartphones, while feature copy claims Android 7.0 and above and iOS 9.0 and above support but says PC or computer is not supported. Confirm compatibility for your device before purchase.

How close should the camera be to the subject?

The listed macro focus range is 3-8 centimeters, but other listing guidance gives 4-12cm and about 2cm-10cm. The usable distance is therefore unclear, so treat this as a close-range inspection camera.

Can it be used in water?

The listing calls the camera and cable waterproof and claims underwater use, but provides no waterproof rating or depth limit.

Does it include an SD card?

SD Card is listed as a media type, but the supplied package information does not confirm that a card is included.
