Snake cameras are primarily used for inspecting the inside of pipes in residential and commercial settings. These flexible tools feature a high-definition camera at the tip, allowing you to view real-time footage of what’s happening deep within your plumbing system—without the need for digging or disassembling anything.
But what exactly makes them so useful? In this article, we’ll break down what a snake camera is, how it works, where it’s most effective, and what to consider if you’re thinking about buying one.
What Is a Snake Camera?
A snake camera is a small, flexible camera attached to a long cable that allows access to tight, hard-to-see spaces. These cameras usually have built-in LED lighting and transmit live video to a handheld monitor or smartphone.
Some professional equipment, like Sanyipace sewer camera products, most of which are equipped with features such as HD video, zoom, audio recording, and locating beacons, can help us have an effective way of troubleshooting situations that arise inside the pipes.
What Are Snake Cameras Used For?
The main uses of snake cameras include the following:
- Pipe and drain inspection – Check for clogs, cracks, or leaks inside plumbing lines.
- Sewer line diagnosis – Identify root intrusion, corrosion, or collapsed sections.
- HVAC system inspection – Look inside air ducts or ventilation systems.
- Wall cavity inspection – See behind walls without cutting them open.
- Automotive repair – Examine tight engine areas or inside cylinders.
- Search and rescue – Locate people or objects in confined or hard-to-access spaces.
- Pest detection – Find rodents or insect nests in hidden areas.
- Home maintenance – Retrieve lost items from drains or inspect crawlspaces.
Primary Uses of Snake Cameras in Plumbing
1. Drain and Sewer Line Inspections
The most common use of snake cameras is inspecting drains and sewer lines. If a homeowner reports slow drainage or repeated clogs, we use a snake camera to:
- Locate the blockage
- Identify the cause (tree roots, grease, collapsed pipe, etc.)
- Determine the extent of damage
- Verify the effectiveness of a cleaning job
Rather than digging up the yard or guessing, a snake camera gives us visual confirmation of what’s happening underground.
🔧 Example: I once inspected a kitchen drain with frequent backups. Turned out, the pipe had a belly (a sag), and debris kept settling there. Without the camera, that diagnosis would’ve been pure guesswork.
2. Post-Repair Verification
After unclogging or repairing a sewer line, we use snake cameras to double-check our work. It ensures the line is clean, the joints are sealed, and there are no leftover roots or debris. This final check adds peace of mind for both the plumber and the customer.
Other Common Uses of Snake Cameras Beyond Plumbing
While plumbing remains the most common use, snake cameras come in various sizes and are used across multiple industries. The versions used outside plumbing—like for HVAC, electrical, or automotive work—are typically smaller and more compact, but they follow the same principle: giving users a clear view inside hard-to-reach spaces without destructive work. Here are some key examples:
3. HVAC and Ductwork Inspections
In heating and cooling systems, technicians use smaller snake cameras to look inside ducts and vents. These cameras help detect:
- Mold or mildew buildup
- Blockages (like insulation or pests)
- Leaks or disconnected joints
- Excessive dust impairs air quality
This is especially useful in older homes or buildings with outdated systems.
4. Electrical Work and Wall Inspections
Electricians often use compact snake cameras to inspect inside walls or ceilings before running new wires, especially in finished areas where cutting drywall is undesirable. These tools help:
- Locate existing wiring or conduits
- Identify obstacles like studs, insulation, or hidden pipes
- Minimize damage during installation
5. Automotive and Mechanical Repair
In automotive repair, snake cameras (also called borescopes) are used to peer into tight spaces like:
- Engine cylinders, intake manifolds, or behind dashboards
- Fuel lines, cooling systems, or brake components
- Hard-to-access mechanical areas without disassembly
Many of these cameras now connect to smartphones for instant viewing, making diagnostics faster and more convenient.
Snake Cameras for Homeowners and DIY Projects
Many homeowners will want to purchase a snake camera to do a plumbing inspection of their home; not only that, it can help us find items lost inside the pipes. Typically, this includes:
- Finding lost jewelry in the sewer
- Finding pests or rodents in the walls or attic
- Checking the gutters or roof line with a pole camera
A quality snake camera will pay for itself after just one or two uses, as it can help you avoid repair calls.
What Should You Consider When Buying a Snake Camera?
When shopping for a snake camera (also known as an inspection camera or borescope), it’s important to choose one that fits your specific needs. Here are the key factors to consider:
- Cable Length: Make sure the cable is long enough to reach the areas you need to inspect. For home plumbing, a cable length of 50–100 feet is usually sufficient. Professionals may need longer cables depending on the job.
- Camera Size and Flexibility: Choose a camera head that fits the diameter of the pipes or spaces you plan to inspect. Smaller, flexible camera heads are ideal for navigating tight or curved areas.
- Image Quality: High-resolution cameras with wide viewing angles help you see more details clearly. Look for models that support HD video or at least 720p resolution.
- Built-in Lighting: Since most inspections take place in dark, enclosed spaces, cameras with adjustable LED lights are essential. They ensure better visibility and clearer images.
- Waterproof Rating: The camera and cable should have at least an IP67 waterproof rating to withstand wet or submerged environments, especially for sewer or drain inspections.
- Recording and Storage Options: If you need to save footage for reporting or later review, choose a model with recording capabilities and either onboard storage or SD card support.
- Durability: Rugged cables and reinforced camera heads offer better protection in harsh environments like clogged drains, automotive engines, or HVAC ducts.
- Intended Use: Match the camera to your purpose—whether it’s for plumbing, car maintenance, HVAC, wall inspections, or electrical work. Some cameras come with specialized accessories for different applications.
Final Thoughts
Snake cameras are versatile and can be used to inspect hard-to-reach areas, especially inside pipes, walls, engines, and ducts. Different types of snake cameras can be used in different areas. Whether you are a homeowner dealing with a stubborn blockage or a professional inspecting HVAC systems or electrical work, snake cameras can help you see clearly and avoid unnecessary damage.
When choosing a snake camera, consider your specific needs – cable length, camera size, image quality, and durability are all key. Choosing the right snake camera can save time, reduce guesswork, and make repairs more efficient.
