| Image Sensor | Back-illuminated CMOS sensor, typically 12–20 megapixels for still images | A larger and more sensitive sensor generally improves detail and low-light image quality. |
| Night Illumination | 850 nm infrared illumination for longer range, or 940 nm infrared illumination for reduced visible red glow | The wavelength affects illumination distance, animal disturbance, and camera concealment. |
| Infrared Night Range | Approximately 20–30 m under suitable environmental conditions | Actual performance depends on vegetation, weather, subject reflectivity, and infrared LED output. |
| Photo Resolution | Native capture commonly ranges from 8 MP to 20 MP; buyers should distinguish native from interpolated resolution | Native resolution provides a more reliable basis for comparing image detail between suppliers. |
| Video Capability | 1080p is widely used; higher resolutions may be available, subject to frame rate and file-size limitations | Video resolution should be evaluated together with frame rate, night exposure, audio, and storage requirements. |
| Trigger Speed | Approximately 0.1–0.7 seconds, depending on camera configuration and testing method | Faster triggering helps capture moving animals before they leave the detection zone. |
| Detection Sensor | Passive infrared detection with an adjustable detection angle, commonly about 40°–60° | Adjustable sensitivity and angle can reduce false triggers caused by vegetation, sunlight, or temperature changes. |
| Detection Distance | Typically 20–30 m for field-use models, with performance varying by ambient temperature and target size | A longer advertised distance should be verified using practical field-test results. |
| Image Capture Modes | Single photo, burst photo, video, time-lapse, and hybrid photo-plus-video modes | Multiple modes support ecological surveys, population monitoring, and security applications. |
| Remote Connectivity | Optional cellular data transmission using regional 4G networks; SIM and frequency compatibility must be confirmed | Network bands, coverage, roaming, data charges, and regional certifications affect international deployment. |
| Local Storage | Removable microSD storage, commonly supporting capacities up to 256 GB depending on firmware and file format | Storage capacity determines deployment duration and the number of high-resolution files retained. |
| Power Options | AA alkaline or lithium batteries, rechargeable battery packs, and optional external solar power systems | Power selection should match temperature, transmission frequency, installation access, and project duration. |
| Battery Efficiency | Low-power standby design with configurable transmission schedules and PIR sensitivity | Configurable settings can significantly reduce unnecessary triggers and communication power consumption. |
| Weather Protection | IP66 or IP67 enclosure target for protection against dust and water exposure | The specific IP rating should be supported by test documentation and matched to the installation environment. |
| Operating Temperature | Common professional range: approximately −20°C to +60°C, subject to battery and network conditions | Cold weather can reduce battery capacity, while heat can affect electronics and image performance. |
| Security Features | Password protection, lockable housing, mounting strap, tripod thread, and optional security cable compatibility | Physical and software security reduce theft, tampering, and unauthorized access to field data. |
| Time and Location Data | Date, time, temperature, moon phase, battery level, and optional GPS coordinates embedded in files | Metadata improves the reliability of wildlife research, asset tracking, and incident documentation. |
| Data Protection | Secure account access, encrypted transmission where supported, and controlled user permissions | Security controls help protect sensitive locations, research records, and remotely transmitted images. |
| Compliance Documentation | Request applicable electrical, radio, environmental, and transport documentation for the destination market | Documentation supports customs clearance, legal sale, network activation, and buyer procurement procedures. |
| Supplier Verification | Evaluate sample testing, firmware stability, quality-control records, warranty terms, spare parts, and technical support | A reliable supplier should demonstrate consistent production quality and provide support throughout the product life cycle. |
