FAQs
Q: How far can the DS-2TD4167-50/WY detect people and vehicles?
A: With its 50 mm thermal lens, it can detect human-sized heat signatures at well over 1 km and vehicles at several kilometres, depending on conditions.
Q: Is it suitable for coastal or corrosive environments?
A: Yes. It features an anti-corrosion coating designed for marine, coastal, and harsh industrial areas.
Q: Can it detect fires?
A: Yes. It includes temperature anomaly alarms and dynamic fire detection, allowing it to detect hotspots and smoke before flames are visible.
Q: Does it have PTZ movement?
A: Yes. It offers full 360° continuous pan and –20° to +90° tilt, with up to 200°/s preset pan speed.
Q: Can it operate at night without any lighting?
A: Yes. The thermal channel works entirely without visible light, and the optical channel benefits from low-light sensitivity for better detail in dim environments.
Q: Can I use both optical and thermal views at the same time?
A: Yes. It supports picture-in-picture overlay to see both thermal and optical feeds simultaneously.
Usability Comparison – DS-2TD4167-50/WY vs HM-TD95C8-150ZE4FL/W
| Feature / Use Case |
DS-2TD4167-50/WY |
HM-TD95C8-150ZE4FL/W |
| Thermal Lens |
Fixed 50 mm (FOV ~12.4° × 9.9°) – wide enough for general thermal monitoring but not ultra-long-range zoom |
Motorized 30–150 mm – can zoom thermal in/out for detailed long-range detection |
| Optical Zoom |
40× optical (6–240 mm) – good for medium to long range |
80× optical (10–800 mm) – extreme long-range detail capture |
| Environmental Protection |
IP66 + anti-corrosion coating – built for marine/coastal/industrial |
NEMA-4X anti-corrosion – very high durability for corrosive and extreme conditions |
| Detection Range |
Excellent for 1–2 km detection but fixed thermal lens limits flexibility |
Superior long-range flexibility; can adjust zoom to match detection task |
| Best Use Case |
Fixed patrol patterns, critical infrastructure near coastal or corrosive zones, industrial perimeter defence |
Large-scale farms, borders, or facilities where patrol requires changing zoom levels and extreme long-range identification |
| Weight/Size |
Smaller, lighter – easier to install on medium poles or masts |
Larger and heavier – typically pole-mounted in fixed PTZ housings with reinforced support |
| Cost/Complexity |
Typically lower cost and simpler to deploy/configure |
Higher cost, more complex setup, but much more capable at distance |

Case Study: Patrolling a 1 km Border with the DS-2TD4167-50/WY
Site Overview
Deployment Strategy
1. Camera Positioning
-
Mount the DS-2TD4167-50/WY on a 15 m high mast at or near the midpoint of the 1 km fence line.
-
Height is crucial — the extra elevation increases visible range for both optical and thermal channels and improves line-of-sight over small terrain undulations.
2. Patrol Setup
-
Thermal Channel:
-
Even though it can’t zoom, it can pan and tilt.
-
Divide the 1 km border into 6–8 overlapping thermal view segments (e.g., 125–170 m sections) using PTZ presets.
-
Each preset points the fixed thermal view at a slightly different angle, overlapping the previous segment for coverage.
-
Optical Channel:
-
Linked to thermal view but with 40× zoom for detail.
-
When thermal detects heat in a preset sector, the PTZ system can stop patrol and optical camera will zoom to that exact location for ID/confirmation.
3. Intelligent Rules
-
Configure line-crossing rules parallel to the fence line in each thermal preset sector.
-
Enable human/vehicle classification to cut false alerts from livestock or wind-blown vegetation.
-
Set fire/smoke detection on each preset sector to provide early warning for bushfires or smouldering equipment.
4. Patrol Timing
5. Integration
-
Connect to an NVR with thermal event bookmarking, so all detections are searchable by alarm type.
-
Optional: integrate with sirens or floodlights along the fence for deterrence when alarms trigger.
Operational Example
-
Patrol Start: Camera begins at Preset 1 (north end of fence), slowly panning thermal view down the line in pre-set jumps.
-
Detection Event: At Preset 4, thermal detects a warm moving shape (human) approaching fence at 600 m from north end.
-
Auto-Response:
-
Patrol halts.
-
Optical zoom instantly moves to 20×–30× for detailed colour view of person.
-
Snapshot sent to owner’s phone with thermal and optical overlay.
-
Optional deterrent: on-board speaker plays a pre-recorded warning.
-
Post-Event: Once alarm clears, patrol resumes at the next preset in sequence.
Key Takeaways for This Model
-
Thermal’s fixed FOV means you patrol by moving the camera, not by zooming thermal.
-
Optical zoom is used only when you need detail after detection.
-
The design excels when you can give it elevation and clear sight lines — the fixed thermal lens still covers significant distances (1–2 km detection) if mounted high enough.
