Frequently Asked Questions

Sewer cameras can typically reach depths of 20m to 300m depending on the model. Cable length determines how far into a pipe you can inspect. The camera can work at any depth as long as the cable reaches. For residential use, 30-50m is usually sufficient. For municipal or industrial applications, 100m-300m cables are available.

For a 2-inch pipe, we recommend a 9mm or 7mm camera. Both sizes will fit easily and provide good visibility. The 7mm is better for very tight spaces, while the 9mm offers slightly brighter LED lighting. Larger cameras like 23mm are better suited for pipes 4 inches and above.

Standard cameras show whatever orientation the cable is twisted in, resulting in upside-down or rotated images. Self-leveling cameras use gyroscope technology to automatically rotate the image display so it always appears upright, making inspections much easier and more intuitive.

In most cases they are the same equipment - the terms "drain camera" and "sewer camera" both describe a push-rod inspection camera used to look inside pipes. The name usually just reflects the pipe size being inspected: smaller residential drains typically use 7mm-9mm heads, while larger sewer and municipal lines may use bigger cameras or crawler robots.

For home use, a 30m 7mm self-leveling sewer camera with a built-in locator is the best all-round choice. It fits 1-4 inch residential pipes, records 1080P video, and the locator lets you find blockages underground without digging. Our SZGOING 30M model is designed exactly for this application.

A sewer camera with locator contains a 512Hz sonde transmitter in the camera head. This emits a radio signal that penetrates soil and concrete. A separate locator device held above ground detects this signal, displaying depth and directional guidance to pinpoint the camera's exact underground position.

Self-leveling technology uses a gyroscope sensor to detect the camera head's orientation. The system automatically rotates the video image so it always displays upright on the monitor, regardless of how the cable is twisted inside the pipe. This makes inspections much more intuitive and reduces eye strain.

Yes, a 7mm camera head easily fits into a 1-inch (25mm) pipe with room to spare. There's ample clearance for water flow during inspection, making the 7mm model ideal for tight residential drain lines, HVAC ducts, and automotive applications.

Push cameras (like most sewer cameras) rely on manual pushing of the flexible cable through the pipe. Crawler robots have wheels or tracks that propel themselves through larger pipes (typically 6 inches and above). Crawlers can navigate around obstacles and cover longer distances more efficiently.

IP68 is the highest dust and water protection rating. The first digit (6) means complete dust protection. The second digit (8) means the device can be submerged in water beyond 1 meter for extended periods. This is essential for sewer and drain cameras that operate in wet, muddy environments.

Yes. Most professional sewer cameras include built-in DVR recording to an SD/TF card, so you can capture inspection footage for reports and documentation. Some models also support photo capture, date/time stamping, and 5x digital zoom. Check the model specs for DVR and storage support.

Yes. Long-cable models (100m) with a 7mm head are well suited to water wells, boreholes, and deep pipelines. We recommend a model with a high-strength fiberglass push rod and optional 512Hz locator for deep inspections, such as our 100M borehole camera systems.

Both fit pipes from 1 inch upward. The 7mm head is the better choice for very tight pipes, 1-2 inch residential drains, and getting around sharp bends with less risk of sticking. A 9mm head can carry slightly brighter LEDs and a larger lens. For pipes 4 inches and above, 23mm heads provide more light and a wider view.

To maintain your pipe inspection camera: 1) Rinse the camera head and cable with clean water after each use. 2) Check and clean the lens regularly. 3) Inspect cables for damage or wear. 4) Store in a dry, temperature-controlled environment. 5) Calibrate sensors periodically. 6) Keep connectors clean and dry.

For self-leveling cameras, calibration should be done monthly or after 50+ hours of use. Check your manufacturer's guidelines. Calibration ensures the gyroscope accurately maintains upright image orientation. Most systems have a built-in calibration mode accessible through the menu.

For typical residential drain inspections, 30m-50m is usually sufficient. Most home drain lines are under 30m from entry point to main connection. If you need to inspect longer runs or multiple rooms, consider 50m. Commercial or municipal use typically requires 100m or more.

720P is adequate for basic inspections and smaller pipes. 1080P (Full HD) provides excellent detail for most professional use and is our recommended minimum. 4K is ideal for large pipes where you need to see fine details at distance, or when creating documentation footage.
