Pipeline Leak & Intrusion Monitoring Solution
Integrate DAS, smart pipeline sentinels, fixed cameras and acoustic leak monitors to protect long-distance oil and gas pipelines from third-party damage, intrusion, abnormal vibration and fixed-point leakage risks.
A single pipeline route can face both intrusion and leakage risks.
Long-distance oil and gas pipelines often pass through remote areas, roads, construction zones, farmland, villages and unmanned stations. Operators need continuous route awareness, high-risk point protection, alarm verification and fixed leak warning.
- Third-party excavation, mechanical digging and unauthorized construction near pipelines.
- Vehicle movement, manual digging, fence intrusion and abnormal ground vibration.
- Valve group, pipeline station, gas well and exposed equipment leakage risks.
- Need for remote alarm, visual confirmation, location data and dispatch evidence.
Four monitoring layers for pipeline security and leak warning.
The solution should not present every device as doing the same job. DAS covers the long corridor, HZ-PS-20A protects high-risk ground activity points, cameras verify events visually, and HZ-WL-15A adds fixed acoustic leak monitoring around stations and valve groups.
DAS route sensing
Use optical fiber as a distributed sensor to monitor vibration and acoustic events along the full pipeline corridor.
Smart sentinel
Deploy HZ-PS-20A at high-risk sections to detect excavation, mechanical activity and vehicle intrusion.
Camera verification
Use fixed acoustic, PTZ or explosion-proof camera systems for visual confirmation and station monitoring.
Fixed leak monitor
Use HZ-WL-15A around gas wells, valve groups and pipeline stations for acoustic leak early warning.
Match each device to the right pipeline monitoring job.
This page can include cameras, DAS, HZ-PS-20A and HZ-WL-15A together, as long as each product has a clear role in the overall pipeline protection workflow.
HZ-iDAS Series Distributed Acoustic Sensing
Use DAS as the backbone for long-distance pipeline corridor monitoring. One sensing fiber provides distributed vibration and acoustic monitoring along the route, helping operators detect and locate digging, vehicle movement, intrusion and abnormal pipeline events.
- Use for long pipeline routes and continuous corridor monitoring.
- Use when event location along the route is required.
- Use when field power at every sensing point is not practical.
HZ-PS-20A Smart Pipeline Sentinel
HZ-PS-20A is the key product for pipeline anti-intrusion and third-party damage prevention. It combines ground vibration sensing, embedded AI recognition, dual HD cameras, solar power, 4G communication and Beidou/GPS positioning for remote pipeline sections.
- Use at construction-prone sections, road crossings and pipeline marker posts.
- Use where illegal excavation, mechanical digging or vehicle intrusion is a major risk.
- Use when visual evidence and accurate location are needed for dispatch.
Fixed Acoustic, PTZ and Explosion-Proof Camera Systems
Cameras are best positioned as the verification and station-monitoring layer. Fixed acoustic cameras, PTZ cameras and explosion-proof acoustic + methane laser cameras can help operators confirm alarm areas, inspect pipeline stations, monitor valve facilities and provide visual evidence after an event.
- Use around valve stations, pipeline stations, compressor areas and LNG/gas handling areas.
- Use after DAS or HZ-PS-20A alarms when visual confirmation is needed.
- Use where remote PTZ inspection can reduce manual visits.
HZ-WL-15A Gas Well & Valve Leak Acoustic Monitor
HZ-WL-15A can be included in this pipeline solution as a fixed acoustic leak monitoring device for gas wells, valve groups, exposed fittings and pipeline stations. It should be positioned as a leak-monitoring supplement, not as the main device for long-distance intrusion detection.
- Use around gas wells, valve groups and pipeline stations.
- Use where continuous manual inspection is difficult or unsafe.
- Use together with gas sensors, SCADA and site safety systems.
From event detection to dispatch evidence.
The page can explain the solution as an operational workflow, not just a list of products. This helps buyers understand how the system fits into pipeline patrol, alarm verification and emergency response.
Detect
DAS, ground sensors or leak monitors capture vibration, acoustic or leak-related signals.
Classify
Algorithms distinguish digging, vehicles, intrusion, leak sound or abnormal field events.
Locate
DAS distance positioning, GPS or fixed-point device location helps operators know where to respond.
Verify
HD cameras, PTZ cameras or acoustic images provide visual and field evidence.
Alarm
Events are sent through 4G, Ethernet, HTTP, Modbus TCP or platform interfaces.
Respond
Teams dispatch patrol, maintenance or emergency response based on event type and priority.
Typical deployment scenarios
Use this section to cover both long-distance pipeline corridors and fixed high-risk assets along the route.
Long-distance pipelines
DAS provides route-level acoustic and vibration monitoring along oil, gas and utility pipelines.
Road crossings
HZ-PS-20A can be installed near road crossings and construction-prone areas to detect third-party activity.
Pipeline marker posts
Smart sentinels can be installed at high-risk marker post locations for unattended monitoring.
Valve stations
Cameras and HZ-WL-15A help monitor exposed valves, flanges, fittings and gas handling equipment.
Remote field sections
Solar-powered and 4G-connected devices support remote and off-grid pipeline environments.
Gas gathering areas
Fixed acoustic leak monitoring helps add early warning around wellhead valves and gathering facilities.
Pipeline architecture, field deployment and verification layers.
These visuals show how DAS, HZ-PS-20A, cameras and HZ-WL-15A work together across the pipeline route, high-risk sections and station assets.
When to use DAS, HZ-PS-20A, cameras and WL15A

Make alarms usable for pipeline operation teams.
A pipeline monitoring page should emphasize the output that operators can act on: event type, location, time, image evidence, leak alarm status and platform integration. This is more persuasive than only showing device specifications.
- Event classification: digging, vehicle movement, intrusion, leak sound or abnormal vibration.
- Location output: DAS distance position, Beidou/GPS or fixed monitoring point ID.
- Evidence output: HD image, video, acoustic image, alarm record or platform screenshot.
- Communication: 4G, Ethernet, HTTP, WebSocket, RTSP or Modbus TCP depending on device.
Common questions
Should HZ-WL-15A be included in this page?
Yes. HZ-WL-15A can be included as the fixed leak monitoring layer for gas wells, valve groups and pipeline stations. It should not be presented as the main long-distance intrusion monitoring device.
What is the difference between DAS and HZ-PS-20A?
DAS is best for continuous long-distance route monitoring along optical fiber. HZ-PS-20A is better for high-risk point protection, such as marker posts, road crossings and construction-prone sections where excavation or vehicle intrusion needs local verification.
Where should cameras be placed in the solution?
Cameras should be positioned as the visual verification and station monitoring layer. They are useful around valve stations, compressor stations, pipeline stations and locations where alarms need visual confirmation.
Can this solution support third-party damage prevention?
Yes. The core products for third-party damage prevention are DAS for route-level monitoring and HZ-PS-20A for high-risk point detection of excavation, digging, vehicle movement and unauthorized construction.
Can one product cover every pipeline risk?
Usually not. Long-distance routes, high-risk construction zones, station equipment and gas leak points have different sensing requirements. A layered solution is easier to explain and more credible for engineering buyers.
