Klein Tools Inspection Camera ET21 5 Foot Borescope (5.5mm Waterproof Cable Wireless WiFi Smartphone App 480p Video Conduit Wall Void Diagnostic)

Inspect Pitch-Black Wall Voids and Sealed Conduit Runs via Smartphone App Video Integration

The Klein Tools ET21 WiFi Borescope is a commercial-grade wireless inspection camera engineered to deliver real-time visual diagnostics in restricted structural spaces. This professional-grade endoscope generates an independent local WiFi network to transmit 480p live video and still images directly to iOS and Android smartphones from up to 30 feet away. Outfitted with an ultra-slim 0.22-inch diameter camera head mounted on a semi-rigid 5-foot armored cable, this rechargeable diagnostic system navigates deep internal pipeline structures and building voids safely.

Best Used For:

• Internal Wall Diagnostics: Threading through small access ports to inspect structural wall voids, hidden wiring paths, and pipe insulation without destructive cutting.
• Electrical Conduit Routing: Verifying clear paths or locating blockages inside dark commercial conduit pipes and structural junction arrays.
• Wet Pipeline Inspections: Navigating through wet plumbing assemblies, drainage lines, and HVAC evaporator coil housings using the fully submersible camera module.

Key Performance & Safety Features

• Autonomous WiFi Connectivity: Emits an independent wireless signal linking straight to smartphones up to 30 feet away without requiring external internet infrastructure.
• Ultra-Slim 5.5mm Camera: Mini 0.22-inch profile probe snout slips cleanly into constricted spaces, small bore drill holes, and complex mechanical manifolds.
• IP67 Waterproof Cable: Reinforced 5-foot camera arm resists liquid submersion, moisture ingress, and plumbing fluid corrosion.
• High-Output Adjustable LEDs: Integrated illumination array provides customizable light levels to capture bright visual frames inside unlit spaces.
• Long-Life Lithium-Ion Core: High-capacity rechargeable internal battery provides up to 8.5 hours of continuous field application run time.

Technical Specifications

PRO-TIP: When routing the 5-foot armored line into multi-angle pipe bends or deep wall voids, shape the first 6 inches of the semi-rigid tip into a modest, slight compound curve before introduction. This intentional bend permits you to scan broad internal spaces and easily rotate the entire cable housing to bypass tight corner blocks.
