Field of view and DORI distances
The angles come from the manufacturer’s documentation for this model. A level’s distance is how deep along the camera axis the required pixel density holds; in practice the result also depends on light, viewing angle and video compression. The values may differ from the DORI in the datasheet: manufacturers calculate it by their own method, here it strictly follows the IEC 62676-4 density thresholds.

Dahua IPC-HFW2431DG-4G-SP-EAU-B is a 4 MP bullet IP camera with a built-in 4G module, designed for installation where there is no wired network or where running one is not economically viable. The camera connects to the internet via a mobile operator's SIM card and transmits real-time video without additional network equipment. This makes it the optimal choice for temporary sites, remote locations and rapidly deployable video surveillance systems.
Advantages
- Built-in 4G module: installation anywhere without cabling and without dependence on Wi-Fi
- 4 MP resolution: sufficient detail for identifying people and vehicles
- H.265 compression: economical video transmission over the mobile network at high picture quality
- Fast deployment: the camera is ready to work immediately after the SIM card is inserted and the unit is mounted
- IP67 protection rating: reliable operation in outdoor conditions in any precipitation
- Autonomy: requires no network infrastructure, which lowers installation costs
Applications
- Construction sites and temporary facilities without permanent infrastructure
- Remote warehouses, farmland and rural areas
- Site security during construction or renovation periods
- Rapid response: prompt deployment of video surveillance anywhere in the country
