The AUTOOL SVB403 automotive engine borescope camera is designed for nondestructive visual inspection in narrow, curved, and hard-to-reach areas such as automotive evaporators, combustion chambers, intake and exhaust passages, catalytic sensor areas, mechanical cavities, and pipe interiors. With a 6.5mm dual-lens probe, 210° two-way articulation, front / side camera switching, 4.3-inch HD display, 32GB storage, IP67-rated probe protection, and high-temperature alert, SVB403 helps technicians inspect internal problems without unnecessary disassembly.
The SVB403 probe is designed for automotive inspection, but the lens and cable should not be used in high-temperature engine conditions. Use the camera after the engine has cooled, and avoid prolonged direct contact with water, oil, or corrosive liquids.
Use Below 75°C Recommended
The inspection camera lens is not resistant to high temperatures. For safer use and longer service life, inspect under cold conditions and use below 75°C whenever possible.
Over-Temperature Alert Above 80°C
The smart sensor triggers an alarm and displays a warning when the temperature exceeds 80°C. The image resumes once the temperature drops.
Do Not Exceed Manual Limit
Do not place the probe in an environment above 85°C. High-temperature damage is considered abnormal damage and is not covered by free warranty.
Cool Engine Before Inspection
When an engine has just stopped, its temperature can reach 80°C to 100°C or higher. It is recommended to wait 1-2 hours for the engine to cool down.
IP67 Probe, Not Full Device Immersion
The probe / lens area is IP67-rated for water, oil, and dust resistance, but the host should not be soaked or exposed to water, oil, or corrosive liquids for long periods.
Keep The Borescope Clean
Keep the articulating borescope clean, avoid prolonged exposure to direct sunlight, and protect the device from corrosive liquids and harsh storage conditions.

SVB403 supports 210° two-way rotation and uses two lenses: a front lens and a side lens. SVB405 and SVB408 support 360° four-way rotation and use one lens. SVB405 has a 2-megapixel camera, while SVB403 and SVB408 have 1-megapixel cameras. SVB403 has a 4.3-inch screen, while SVB405 and SVB408 have 4.5-inch screens. SVB403 uses a 6.5mm lens, SVB405 uses a 6.45mm lens, and SVB408 uses a 3.9mm ultra-thin lens. SVB405 and SVB408 have 8× zoom, while SVB403 is positioned around dual-lens front / side inspection.
Yes. SVB403 has two lenses: a front lens and a side lens. This makes it easier to inspect both forward-facing and side-facing areas without repeatedly adjusting the probe angle.
Use SVB403 after the engine has cooled down. It is recommended to inspect below 75°C. The device triggers an over-temperature warning above 80°C, and the manual limit for the probe should not exceed 85°C. High-temperature damage is considered abnormal damage and is not covered by free warranty.
The probe / lens area is IP67-rated for water, oil, and dust resistance, making it suitable for wet pipes and oily inspection conditions. However, the host should not be immersed, and the device should not be exposed to water, oil, or corrosive liquids for long periods.
Press and hold the M key for about 2 seconds to switch between the front lens and side lens.
SVB305 supports 210° two-way rotation, while SVB308 supports 360° four-way rotation. SVB305 has a 2000mAh lithium battery, while SVB308 has a 2600mAh lithium battery. SVB308 also adds a magnetic and detachable design, allowing the bottom to attach to magnetic surfaces and the screen / handle to detach for easier storage.
SVB302 and SVB303 belong to the AUTOOL borescope family, but the original comparison text contains some mixed wording. Use the comparison chart for final confirmation. In general, SVB303 is positioned as the more advanced option with stronger language and structure design features, while SVB302 remains a more basic inspection camera option.
