FAQ: A 4MP IP dome camera with IR night vision and IP67 waterproofing is designed for 24/7 outdoor surveillance. It delivers high-resolution 4MP video, infrared illumination up to 30 meters in darkness, and withstands harsh weather due to its IP67 dust/water resistance. Ideal for homes, businesses, and industrial sites needing reliable, weatherproof security.
Why Is the Infrared Not Working on Security Cameras?
How Does 4MP Resolution Improve Surveillance Clarity?
4MP resolution (2560×1440 pixels) provides 33% more detail than 1080p, capturing finer elements like license plates or facial features. Advanced sensors reduce noise in low-light conditions, while wide dynamic range (WDR) balances lighting contrasts. This ensures crisp footage for accurate identification and forensic analysis.
The higher pixel density of 4MP cameras allows digital zooming without significant quality loss, making it easier to review critical details post-incident. Compared to 2MP systems, 4MP models cover wider areas with fewer cameras – a single unit can monitor a 40-foot driveway with clear facial recognition at 15 feet. Modern H.265+ compression ensures efficient storage usage while maintaining detail integrity.
| Resolution | Pixel Count | Storage/Day (H.265) |
|---|---|---|
| 1080p | 2MP | 32GB |
| 4MP | 4MP | 48GB |
Why Is IR Night Vision Critical for 24/7 Monitoring?
Built-in infrared LEDs enable night vision up to 30 meters, automatically switching to B/W mode in darkness. Smart IR technology prevents overexposure, while starlight sensors enhance visibility in near-total darkness. This ensures uninterrupted monitoring without visible light, deterring intruders covertly.
Advanced models feature adaptive IR intensity adjustment that prevents “whiteout” effects on close objects while maintaining clarity at longer ranges. Supplemental EXIR 2.0 technology extends illumination range by 40% compared to standard LEDs. For environments requiring complete darkness, these cameras can operate in 0 lux conditions using only infrared spectrum light.
What Does IP67 Waterproof Rating Mean for Durability?
IP67 certification guarantees total dust resistance and protection against immersion in 1m of water for 30 minutes. The dome’s sealed housing prevents moisture ingress, while tempered glass resists corrosion and vandalism. This makes it suitable for coastal areas, heavy rain, and extreme temperatures (-30°C to 60°C).
Which Advanced Features Enhance Security Capabilities?
AI-powered motion detection, two-way audio, and smart alerts reduce false alarms. On-board MicroSD storage (up to 256GB) and ONVIF compliance ensure compatibility with NVRs. Pan-tilt-zoom (PTZ) models offer 360° coverage, while PoE support simplifies installation with a single cable.
How to Optimize Installation for Maximum Coverage?
Mount the camera 8-12 feet high at entry points, avoiding backlighting. Use junction boxes for clean wiring and adjust the 3-axis lens for precise angling. Enable edge computing to minimize bandwidth use and pair with VMS platforms like Blue Iris for centralized management.
