Detailed Specifications and Benefits
The DS-2XM6222G1-IM/ND packs technical capabilities that matter in mobile surveillance. Below is a breakdown of the most important specifications and the practical benefits they deliver.
- Resolution:1920 × 1080 (2 MP) — clear, full-HD images suitable for identification and situational awareness without excessive bandwidth or storage burden compared with higher-resolution alternatives.
- Frame Rate:PAL 25 fps / NTSC 30 fps — smooth live video and playback for typical transport surveillance needs.
- Lens:2.8 mm fixed lens (M12 mount) with ≈105° horizontal field of view — wide coverage ideal for interior cabin views, doorways and near-field scenes.
- Aperture:F1.6 — helps with low-light sensitivity while keeping distortion and aberrations in check for a compact lens design.
- IR Illumination:850 nm IR fill light, up to approximately 10 m (specific to the IM/ND 2.8 mm variant) — provides reliable night and tunnel performance for onboard applications.
- Min. Illumination:0.01 lux @ F1.6 (colour, AGC ON); 0 lux with IR — captures usable colour images in dim light, with IR for no-light conditions.
- WDR & Noise Reduction:120 dB WDR and 3D DNR — preserves details in scenes with backlight and reduces motion/grain noise common in moving vehicles.
- Codecs:H.265 and H.264 (including H.264+/H.265+) plus MJPEG on sub-stream — efficient compression for lower bandwidth and storage use while maintaining image quality.
- Streams & ROI:Main, sub and third streams with ROI support (two fixed regions) — allows prioritising image quality in critical areas while saving bandwidth.
- Smart Detection:Motion, tamper, line crossing, intrusion, object removal, unattended baggage and face/object detection — useful for automated alerts and analytics when integrated with a VMS/NVR.
- Interfaces:Ethernet through a 4-pin M12 aviation connector — a ruggedised connection preferred on vehicles to keep cabling secure and sealed.
- ONVIF & Protocols:ONVIF Profile S/G/T supported; RTSP, TCP/IP, DHCP, DNS, SNMP, ISAPI and SDK — broad compatibility with VMS and NVR platforms.
- Local Storage:microTF (microSD) slot up to 256 GB — enables onboard recording for redundancy or local-only setups.
- Power:PoE 802.3af via 4-pin M12 with max power around 7.5 W — simplifies deployment by carrying data and power over one cable while using an aviation-grade connector for vehicle use.
- Ingress Protection:IP68 metal housing — dust-tight and protected against prolonged immersion, a major plus for exterior or harsh interior areas exposed to moisture and contaminants.
- Operating Temperature:-30 °C to +75 °C — suitable for temperature extremes encountered in vehicles exposed to cold climates or engine/roof heat.
- Rail/Auto Approvals:EN50155, EN45545, E-MARK — indicates the camera meets safety and electromagnetic/thermal requirements for many rail and automotive applications.
Use Cases and Scenarios Where the DS-2XM6222G1 Excels
The DS-2XM6222G1 is optimised for mobile and transport surveillance. Typical deployments and scenarios that benefit from this camera include:
- Passenger cabin monitoring on buses and coaches:The wide horizontal field of view, good low-light performance and on-board storage make the camera ideal for recording passenger activity, deterring vandalism and providing evidence after incidents.
- Doorways and entry/egress points:Mounting near doors captures ingress/egress with a wide enough FOV to see passengers and interactions clearly without needing multiple cameras.
- Interior surveillance on trains and trams:Certifications like EN50155 and EN45545 make the camera suitable for rail vehicles where fire safety and temperature/vibration resilience are mandatory.
- Fleet and commercial vehicle security:For delivery trucks, service vehicles and municipal fleets, the IP68 housing and M12 connector provide durability against weather, vibration and frequent movement.
- Complementing external door or driver-facing cameras:Used in multi-camera systems to cover interior and near-exterior angles, with ONVIF compatibility to integrate into larger VMS or NVR ecosystems.
Comparisons with Similar Products on the Market
When evaluating onboard/mobile IP cameras, buyers typically compare image quality, ruggedness, connectivity and certifications. Here’s how the DS-2XM6222G1 stands in those areas relative to typical alternatives:
- Ruggedness & Connectors:The use of a metal IP68 housing and a 4-pin M12 aviation connector is a common expectation in vehicle cameras. Some lower-cost models use standard RJ45 connectors and plastic housings that are less suited to vibration and ingress—giving the Hikvision model an edge for long-term reliability in mobile environments.
- Certifications:EN50155/EN45545 and E-MARK approvals position this camera favorably for rail and automotive projects. Cheaper cameras may lack these approvals, limiting where they can be legally or safely installed in regulated transport systems.
- Image Processing & Compression:H.265 support and 120 dB WDR are strong points for maintaining detail in variable lighting while conserving bandwidth and storage. Some older or budget models may only offer H.264 and reduced dynamic range.
- IR Range & FOV:The 2.8 mm variant’s ≈105° horizontal FOV and up to 10 m IR range make it well-suited to interior coverage. Cameras designed specifically for long-range exterior monitoring might offer narrower fields and longer IR ranges but would be less useful for interior cabin coverage.
- Integration:ONVIF Profile S/G/T support and standard network protocols enable smooth integration into many VMS platforms. Proprietary cameras without ONVIF support can be harder to integrate or require vendor-specific NVRs.
In short, compared to generic or consumer-grade models, the DS-2XM6222G1 is tailored for the mobile surveillance market with appropriate connectors, approvals and environmental ratings. Compared to other professional vehicle cameras, its balance of 2 MP resolution, efficient codecs and rugged design makes it a competitive choice where cost and durability must be balanced.
Customer Feedback and Installer Perspectives
Public product-specific reviews for onboard/rail-specific hardware are often limited to installer and system integrator reports rather than broad consumer reviews. Common themes that installers and integrators report favorably about cameras like the DS-2XM6222G1 include:
- Reliability in harsh environments:Installers appreciate the M12 connector and IP68 housing because they reduce maintenance visits caused by moisture ingress or loose connections.
- Integration flexibility:ONVIF compatibility and support for H.265 make it simpler to add the camera to modern VMS systems while conserving network and storage resources.
- Image quality vs bandwidth:The 2 MP resolution and H.265 compression are often seen as the right compromise for clear evidence capture without overwhelming fleet networks.
If you are planning a project, ask vendors for field references or installation case studies for vehicles similar to yours; integrators who have deployed the camera on buses, trams or regional trains can provide the most relevant feedback.
Installation, Compliance and Practical Considerations
Proper installation is critical for reliable onboard operation. The camera supports common network protocols (RTSP, DHCP, SNMP) and should be installed by technicians familiar with vehicle power and PoE systems. Key considerations:
- Use certified M12 aviation cables and ensure connectors and gaskets are correctly sealed to maintain IP68 protection.
- De-energise circuits before wiring and follow vehicle/rail regulations when mounting and routing cables.
- Confirm local regulatory approvals (CE/UKCA status may vary) and check whether additional vehicle- or operator-specific certifications are required for your deployment.
- Plan for power consumption (max ≈7.5 W) and whether PoE sources on the vehicle are compatible with 802.3af.
Conclusion: Why the DS-2XM6222G1-IM/ND Is a Strong Choice for Onboard Surveillance
