How do I switch between the front and side cameras?

Press and hold the capture button to switch between the front and side views. The front lens looks ahead; the side lens helps inspect surfaces beside the tip. Adjust the LED brightness for the selected view as needed. See Instructions and Manuals above for the full button guide.

How long is the probe, and how far can the tip bend?

The TD450S Dual Lens has a 5.08 ft / 1.55 m probe with an 8.5 mm tip. The lever moves the tip through up to 210° of two-way articulation. Guide the probe gently; do not force the tip around a tight corner.

What photo and video quality can I capture without a phone?

The built-in 4.5-inch display lets you view and record without a phone or Wi-Fi. This dual-lens configuration captures photos at up to 1920 × 1080 and videos at 1280 × 720. Files save to the included 32 GB microSD card.

Is the entire TD450S waterproof?

No. The IP67 rating applies to the camera probe only. Keep the handheld monitor dry, and follow the product manual for use and cleaning.

What should I do if the side-view light does not turn on?

Check that the side view is selected and increase its LED brightness using the controls in the manual. If it stays dark, contact Teslong support with the model or SKU, a short video showing the screen and probe tip, and any available proof of purchase. Support can assess the next step.

What should I do if the screen says 'No Camera'?

Note whether the camera displayed an image before, when the message appears, and any steps you have tried. Contact Teslong support with the exact model or SKU and a clear photo or short video of the screen. Include available purchase details. The message alone does not identify a failed component.

I received a TD450S as a gift. How do I request support?

Contact Teslong support with the model or SKU and any available order number or receipt. Tell support that the item was a gift and someone else may have placed the order. They can explain what purchase information is needed to review your request under the current policy.

How does TD450S temperature protection work?

When the temperature exceeds 75°C (167°F), the TD450S automatically sounds an alarm. When it exceeds 85°C (185°F), the device automatically shuts off. These are protection trigger points, not continuous operating-temperature ratings.

Two-way dual lens articulation with a 4.5-inch monitor

Two-Way 210° Articulating Inspection Camera

The TD450S is a portable, handheld, multi-function inspection camera. The lever and dual camera lenses allow the camera to look in different directions, while the monitor takes photos or records videos. Easily document your work to reference later or to share with your customers. This is perfect for many applications, such as inspecting engine cylinders, airplane wings, wall boards, and brake systems.

The 5-foot-long probe is bendable, but still fairly stiff to hold its shape well and allow you to form it and insert it into a space. Once it's in position, you can use the control wheel to articulate the tip through 210-degrees of movement.

Front and side views at the tip

Look ahead with the front lens, then switch to the side lens when the subject is across the space. The two views help you inspect from another angle without removing the probe.

Capture the view on the built-in screen

Use the 4.5-inch display to inspect in real time, then save photos or videos to the included 32 GB microSD card. The camera works without a phone.

Adjust the light for a clearer view

Eight adjustable LEDs surround the front camera, with one adjustable LED beside the side camera. Set the brightness for the space you are inspecting.

Guide the camera around a bend

The control lever steers the 8.5 mm probe tip through up to 210° of two-way articulation. The 5.08 ft / 1.55 m probe helps reach the inspection point. The IP67 rating applies to the camera probe only.
