Introduction
Every pipe network in Singapore is different: different diameters, different access points, different levels of debris and flow. RIEZLER built its pipe and sewer inspection range around a simple idea: rather than forcing operators to buy an entirely new camera system for every job type, one modular platform should be able to cover all of them.
As the authorised RIEZLER distributor and authorised service centre in Singapore, VISCOY supplies, commissions, and supports the full RIEZLER line-up: small push camera systems, large push camera systems, small robotic crawler systems, and large robotic crawler systems.
This post walks through each of the four systems, the two advantages that define the RIEZLER approach: high-definition imaging and true component modularity, and the industries in Singapore and the wider region where these confined space inspection systems are already doing the work: marine, oil and gas, power generation, pipelines, sewers, and the built environment.

The Four RIEZLER Inspection Systems
RIEZLER’s range splits along two lines: push camera systems, which are fed through a pipe by hand and robotic crawler systems, which drive themselves through the line on wheels or tracks. Each is offered in a small and large configuration, giving Singapore operators four distinct tools built on a shared control platform.
1. Small Push Camera System
The small push camera system is built for tight-diameter lines and lateral connections: runs that are too narrow or too short to justify sending in a crawler. A semi-rigid push cable carries a self-leveling camera head through bends and offsets, feeding a real-time HD image back to the control unit. Because the reel is compact and hand-portable, this is the system technicians reach for on house laterals, small-diameter drains, and building services work in Singapore where a single operator needs to move quickly between access points.
2. Large Push Camera System
The large push camera system carries the same push-camera principle further, with a stiff, extended-length cable designed for longer municipal and industrial pipeline inspection runs. The heavier-duty push rod manages cable tension automatically over greater distances, reducing operator fatigue on long survey days and keeping footage stable even as the cable pays out over hundreds of metres. This is the system of choice where a push camera is still the right tool, but the line is too long or the diameter too large for the small push system to comfortably cover. Large push camera system also comes with a more powerful LED lighting.
3. Small Robotic Crawler System
Where a line has bends, standing water, debris, or a diameter too small to push a cable through unaided, the small robotic crawler for inspection takes over. A compact tracked or wheeled chassis carries a pan-and-tilt HD camera head into the pipe under its own power, giving the operator full control of direction and camera angle from the surface via a lightweight tether reel. Its smaller footprint suits confined sewer laterals, tight industrial process piping, and vessel or tank inspections where access is restricted — common scenarios across Singapore’s built environment and process industries.
4. Large Robotic Crawler System
The large robotic crawler is the heavy-duty end of the range, built for trunk sewers, culverts, and large-diameter industrial pipelines. A more powerful drive system and a heavier-duty motorised reel give it the traction and cable-handling capacity to cover long, large-bore runs, while the Pan-Tilt & Zoom HD camera head provides the same detailed, steerable inspection view used across the rest of the range, just scaled to match the pipe.
Key Advantages of the RIEZLER System
High-Definition Imaging Across the Range
Every camera head in the RIEZLER line-up, whether mounted on a push cable or a crawler chassis, is built around high definition (HD) imaging. That matters because CCTV pipe inspection footage is only as useful as what it can show an engineer after the fact: hairline cracks, root intrusion, joint displacement, or early corrosion. Sharp, consistent HD video across every system means an operator moving between a small push camera job in the morning and a large crawler survey in the afternoon isn’t trading down on image quality to match the tool to the job.
Modularity: One Platform, Multiple Configurations
The defining feature of the RIEZLER range is that the camera heads, reels, and control units are designed to be swappable across the platform rather than locked to a single system. An operator does not need to own four completely separate rigs to cover four job types. The same control unit can be paired with different camera heads and reels as the application demands.
- Camera heads — swap between push-camera heads and crawler-mounted pan-and-tilt heads to match the access method to the job
- Reels — move between compact hand-portable reels and motorised, extended-length reels depending on pipe length and diameter
- Control units — a shared control platform operates across configurations, so operators train once and work across the whole range
The practical effect is lower cost of ownership. Instead of budgeting for four independent systems, an operator expanding their capability in Singapore can add the specific camera head or reel needed for a new application, rather than a full duplicate system.
| Approach | What You Buy | Outcome |
| Conventional (non-modular) | A separate camera, reel, and control unit for every pipe size and job type | Multiple complete systems purchased, serviced, and transported independently — higher capital and lifecycle cost |
| RIEZLER Modular | One control unit; swappable camera heads and reels matched to the job | A single control platform covers small push camera, large push camera, and crawler configurations — lower cost to expand the fleet |
Where RIEZLER Systems Are Used in Singapore and Beyond
Because the platform scales from small push cameras to large robotic crawlers, RIEZLER systems are deployed across a wide span of industries in Singapore, each with its own inspection demands:
- Marine — hull piping, ballast lines, and shipboard systems where confined access and corrosion monitoring are constant concerns, relevant to Singapore’s marine and offshore sector
- Oil and gas — process piping and pipeline sections requiring detailed internal condition assessment without taking the line out of service longer than necessary
- Power generation — cooling water lines, condenser tubing, and plant piping inspected during planned outages
- Pipelines — long-run transmission and distribution pipelines surveyed with the large push camera or large crawler systems
- Sewers — municipal and lateral sewer lines, the core application for both crawler configurations and the large push camera system
- Built environment — building drainage, HVAC ductwork, and facility piping in Singapore’s commercial and residential developments, typically covered by the small push camera system
