Teslong Probes and Replacement Camera Cables
Replacement and extra camera probes for Teslong monitors
Teslong camera probes are sold on their own, so you can replace a damaged cable or add a second view to the monitor you already own — single, dual, triple or rotating lenses from 3.9 mm to 8.5 mm.
Each probe works only with the monitors listed for it, so check the model on your screen unit first: the NTS500 and NTS500B take different probes.

Buying guide
How to Choose a Replacement Camera Probe
Four checks, in this order, before you add a probe to the cart.
Match the Probe to Your Monitor
Read the model on your monitor and find it in the probe's compatible list. NTS-series probes list NTS monitors; the 8.0 mm Dual-Lens USB probe is for the NTS500B and MS450 only. The triple-lens probe comes in an NTS300/NTS500 version and an NTS600/NTS700/NTS800 version.
Choose the Diameter
Match the probe to the smallest opening you inspect. The 3.9 mm probe is the slimmest here; 5.5 mm probes come in single- and dual-lens versions; 7.9–8.5 mm probes carry triple, rotating and longer-cable options.
Single, Dual, Triple or Rotating Lens
A single lens looks one way. Dual-lens probes toggle between a 70° front and a 70° side camera for a 140° total field of view. The triple-lens and rotating dual-lens probes add more angles from one insertion.
Cable Length and Accessories
NTS probes run from 3.2 ft to 16 ft; the USB probe goes up to 50 ft. The 5.5 mm single-lens, 8 mm dual-lens, USB and triple-lens probes include accessories; the 3.9 mm and 5.5 mm dual-lens probes do not.

FAQ
Frequently Asked Questions
Common questions about inspection cameras and replacement camera probes.
What is the difference between a borescope and an endoscope?
Generally, “endoscope” is a medical term for a surgical device, but we frequently call our products “industrial endoscopes” to avoid confusing them with medical endoscopes. Teslong does not make any medical-grade surgical products. “Borescopes” is a term that is basically interchangeable with “industrial endoscopes” however we refer to all of our firearm inspection cameras as “borescopes” and the rest of our inspection cameras as “industrial endoscopes.”
What is a digital inspection camera used for?
Digital inspection cameras are good for looking anywhere that is difficult to see or access with the naked eye. This could be as simple as looking under the refrigerator for lost car keys or it could be a technical engineering application like performing a visual inspection on an aircraft engine. Digital inspection cameras have many uses, but most commonly they are used to look inside the wall of a house to aid running electrical or audio wiring and also for looking inside combustion chambers of automobiles to inspect for proper valve function.
Can you hire an inspection camera?
You can hire mechanics or home inspectors to perform inspections using inspection cameras, but generally you wouldn’t specify the tools they use to perform their work. Complicated and expensive inspection cameras can be rented, but this is usually only done by trained professionals. Most consumer digital inspection cameras are inexpensive enough that you can just buy them to perform the inspection yourself.
What camera do home inspectors use?
Home inspectors use whatever industrial endoscope camera they trust to get the job done. Ultimately, they need to get a good visual on their subject such that they can confidently make an accurate assessment of whatever they are looking at.
Do you need a borescope inspection camera?
Borescope inspection cameras are handy tools that save time and money - anyone who regularly performs do-it-yourself work around the house or automobiles should have one in their toolbox.
How do snake cameras work?
Snake cameras are a slang term for borescope inspection cameras , or industrial endoscopes. Snake cameras have a digital camera on the end of a rigid or flexible probe that is designed to access areas that you normally can’t see with the naked eye, thereby eliminating time-consuming disassembly or destructive inspection processes.
Which replacement camera fits the Teslong NTS500 or NTS500B?
The two monitors take different probes. The NTS500B uses the Dual-Lens USB Camera Probe — 0.31 in (8.0 mm), which must be used with the NTS500B or MS450 monitor.
The NTS500 is listed for the 3.9 mm and 5.5 mm single-lens probes, the 5.5 mm and 8 mm dual-lens probes, the NTS300/NTS500 version of the triple-lens probe, and the rotating dual-lens probe (certain NTS500 monitors require a firmware upgrade for it).
Do I need a firmware update to use the rotating dual-lens probe?
Possibly. The rotating dual-lens probe is compatible with NTS300*/430/500*/600/700 and WF200 Teslong monitors, and certain NTS300 and NTS500 monitors require a firmware upgrade first. Contact Teslong support with your monitor model before ordering if you are unsure.
Which probes come with a hook, mirror and magnet?
The 5.5 mm single-lens, 8 mm dual-lens and 8.0 mm dual-lens USB probes include a hook, mirror and magnet, and the triple-lens probe lists accessories as included. The 3.9 mm single-lens and 5.5 mm dual-lens probes do not include any accessories.
Not Sure Which Probe Fits?
Tell us your monitor model and what you inspect, and we'll confirm the right probe — or check the comparison table above.
Replacement Camera Probes for Teslong Inspection Cameras
A Teslong camera probe is sold without a monitor, so you can replace a damaged cable or add a new view to the inspection camera you already own. This collection covers replacement camera probes sold separately for compatible Teslong monitors.
Match the Probe to Your Monitor
Compatibility is model-specific. The NTS-series probes each list the NTS monitors they work with — for example, the 5.5 mm single-lens probe must be used with NTS300, NTS500 or NTS700 monitors. The NTS500B and MS450 take a different probe: the 0.31 in (8.0 mm) dual-lens USB probe, with cables up to 50 ft. The triple-lens probe comes in an NTS300/NTS500 version and an NTS600/NTS700/NTS800 version, and certain NTS300 and NTS500 monitors need a firmware upgrade for the rotating dual-lens probe.
Diameter, Lens and Length
Choose the 3.9 mm probe for the smallest openings, 5.5 mm for tight spaces with a single or dual lens, or 7.9–8.5 mm for triple-lens, rotating and longer-cable options. Dual-lens probes switch between 70° front and side cameras. Probes carry a 12-month warranty, with free US shipping on orders over $199.
