ORLANDO, FL, United States. ROVE INNOTECH today launches the ROVE RS4 Four-Way Articulating Borescope, the newest addition to its professional visual inspection lineup. Building on the two-way RS2, the RS4 gives mechanics, plumbers, HVAC technicians, electricians, and serious DIYers something the category has been missing: a joystick that steers the camera tip in every direction, not just one plane.
Most inspection cameras ask you to compromise. A fixed probe shows you whatever is straight ahead. A two-way probe lets you sweep up and down, or left and right, but not both. The moment your target sits off to the side, around a bend, or anywhere on the far wall of a cylinder, you're pulling the probe out, twisting the cable, and hoping the next attempt lands better.
The RS4 was built to end that guesswork. As a true four-way, 360° articulating borescope, it pairs joystick-driven steering with a 6.2mm probe, a 1080P Full HD camera, and a 4.3-inch IPS display, so you can survey an entire cavity from a single insertion point.
Why ROVE Built the RS4
ROVE INNOTECH is an American consumer electronics brand headquartered in Orlando, Florida, founded in 2015 and best known for the ROVE dash cam line trusted by over a million drivers. Since bringing that same rugged-electronics discipline into visual inspection with the RS2, ROVE has heard the same request from shop techs and serious DIYers: give us full control over where the camera looks, not just one axis of it.
The RS4 is the answer. It carries forward the same 6.2mm probe, 1080P imaging, and standalone 4.3-inch display that made the RS2 reliable in the field, and adds a joystick-controlled, 360° articulation system built for anyone searching for a borescope camera with full directional control.
Who the RS4 Is For
The RS4 is built for anyone whose inspection point could be anywhere around the probe, not just above or below it:
- Auto mechanics and technicians using an engine inspection camera to check cylinder bores, piston crowns, valve areas, and turbo housings through a spark-plug-hole-class opening.
- Plumbers and HVAC technicians working single-access jobs where the defect could be on any wall of the cavity.
- Electricians tracing wiring through irregular wall voids and conduit runs.
- Shop owners looking to cut reinsertions per job, since every withdraw-and-reangle cycle is billable time a customer doesn't see reflected on the invoice.
- Serious DIYers checking wall cavities, ductwork, and engine bays from a single opening rather than drilling a second access point.

A Feature-by-Feature Tour of the ROVE RS4
True Four-Way 360° Articulation
The RS4's joystick moves the camera tip up, down, left, and right, and combining those inputs lets you sweep a full circle around the probe's axis without repositioning the cable itself. That means one access hole can cover a wall cavity's top, bottom, and both side surfaces. Inside a cylinder or pipe, you can follow the bore around its full circumference instead of withdrawing and rotating the cable to check the opposite wall.
The articulation mechanism is rated for at least 15,000 cycles, a durability spec built for the repetitive demands of professional service work, and a common benchmark for anyone comparing a 360 degree articulating borescope buying guide against real-world use.
A 6.2mm Probe on a 1.6m Flexible Metal Hose
The RS4 uses the same slim 6.2mm probe as the RS2, sized for spark-plug-hole-class openings and similarly narrow access points, mounted on a 1.6m flexible metal hose. Probe diameter, reach, camera resolution, and focus range are identical across both models. What changes is how many directions the tip can steer once it's inside.
1080P Camera with a 90° Wide-Angle Lens
The RS4 captures at 1080P Full HD through a 90° wide-angle lens with a 20-100mm focus range, broadening what's visible at a given distance and keeping detail sharp at typical inspection ranges. A 2x and 4x digital zoom lets you pull in tight on fine cracks, scoring, or buildup without losing your steady probe position.
A 4.3-Inch IPS Display Built Into the Handle
The joystick, the display, and the camera are one object. There's no phone, no app, and no Wi-Fi pairing to manage while your hands are already busy holding a probe. The 4.3-inch IPS screen (480×272) shows the live feed directly on the handle, and recordings save straight to a microSD card instead of a phone's storage, making the RS4 a genuine borescope with built-in screen rather than a phone-dependent camera.
Full Audio and Video Recording, Not Just Stills
Beyond JPG photo capture, the RS4 records MOV video with synced audio, so you can narrate what you're seeing in real time (calling out a crack, a leak point, or a wiring issue as you find it) instead of trying to reconstruct the context later from a silent clip. That audio compatibility matters most when footage needs to be shared with a customer, a colleague, or another technician who wasn't standing next to you during the inspection. Everything records on-device to microSD, so a finding is documented the moment you see it.
Dual Lighting for Full Control
Six high-brightness LEDs are built into the probe tip with four adjustable brightness levels, so you can dial lighting up for a dark cavity or down to cut glare off polished metal. Two additional work lights on the rear of the handheld unit illuminate the surrounding workspace at the same time.
IP67-Rated Probe and Camera Head
The 6.2mm probe and camera head are IP67 rated for dust and water ingress protection, safe for use in wet drain lines, damp wall cavities, and oily engine bays. As with the RS2, this rating covers the probe and camera head only. The handheld display unit is not waterproof and should stay clear of standing water and direct submersion.
On-Device Recording, No App Required
The RS4 captures JPG photos and MOV video with audio, straight to its own microSD card. Transfer files by USB-C or a card reader. No app, no Wi-Fi setup, no pairing step. Power on and inspect.

RS4 vs. RS2: Choosing the Right Model
Both models share the same 6.2mm probe, 1.6m reach, 1080P camera, and 4.3-inch display, so you're choosing steering axes, not image quality:
- Choose the RS4 if your targets could be anywhere around the probe's axis: cylinder bores, turbo housings, wall voids entered from a single hole, or any job where you need to survey a full cavity without pulling the probe back out.
- Choose the RS2 if your inspections are mostly a single-plane sweep: duct runs, straight pipe sections, or household cavities you're checking from above or below

Searching for a two-way vs four-way borescope articulation comparison? The short version: four-way covers everything two-way does, plus left-and-right control on the same joystick.

ROVE RS4 FAQs
Does four-way articulation mean the tip spins in a full circle?
No. The joystick moves the tip in four directions (up, down, left, right), and using them together covers a 360° range around the probe, not a continuous spin.
Is the entire RS4 waterproof?
The 6.2mm probe and camera head are IP67 rated. The handheld unit with the screen and controls is not waterproof and should be kept away from standing water.
Do I need a phone or app to use the RS4?
No. The RS4 is a standalone inspection camera with its display, controls, and camera built into one handheld unit.
Can the RS4 record audio along with video?
Yes. The RS4 records video with synced audio directly to its microSD card, so you can narrate findings as you inspect instead of relying on a silent recording.
Can this inspection camera replace a professional diagnostic tool?
No. It's a visual inspection tool that complements diagnostics (electronic scan tools for engines, licensed inspection for homes) rather than replacing them.
