A Dahua 4MP IP camera records at 2560 × 1440 resolution, producing approximately 3.7 million pixels per frame. This is about 1.78 times the pixel count of 1080p, providing additional detail for live monitoring, playback, and post-event review without the storage demands of higher-resolution 4K cameras.
The balance between image quality and recording efficiency makes 4MP Dahua cameras suitable for many professional surveillance systems, including retail stores, offices, schools, warehouses, parking areas, and residential properties.
A 4MP camera provides more image detail than 1080p while generally requiring less bandwidth and storage than an 8MP or 4K camera. With the correct lens, mounting position, lighting, and subject distance, the additional pixel density can improve facial identification, transaction review, and other evidence-based monitoring tasks.
Many Dahua 4MP cameras support H.265 or H.265+ video compression to reduce bandwidth and storage consumption. Actual bitrate, frame rate, and recording duration vary by model, image settings, scene activity, number of cameras, and NVR configuration.

Recommended applications:
When comparing Dahua 4MP PoE cameras, consider the lens and viewing angle, infrared distance, low-light capability, weather-resistance rating, vandal-resistance rating, audio support, and available AI analytics. These specifications vary by model, so select the camera according to the required identification distance and installation environment.
