Thanks to the use of the CMOS 1/2.8" converter and wide dynamic range (WDR 120 dB), By Camera provides a clear Picture even in difficult lighting conditions, from 0.0002 lux in black and white mode to full darkness thanks to the built-in IR bulb with a range of up to 60 m.
By Camera has Lens vari-focal with a 2.7-13.5 mm focal variable, allowing flexible adjustment of the field of view (from 30° to 109° horizontal).
Smart Image Analysis (IVS) features include intrusion detection, perimeter protection, and human and vehicle recognition, which increases monitoring efficiency.
Technology AI SSA (Smart Scene Adaptation) automatically adjusts Cameras settings to environmental conditions.
By Camera supports H265/H264 compression, offering high image quality with optimal bandwidth usage.
Additional Functions include.
3D NR noise reduction, Image Stabilization EIS and the possibility to define privacy zones.
To make Camera resistant to atmospheric conditions (IP67) and vandalism acts (IK10 optional), making it ideal for external applications.
It also supports interoperability with other manufacturers' systems through compliance with ONVIF and the use of protocols such as HTTP, RTSP or SMTP.
The power supply is made via PoE (802.3af) or 12 VDC, and the consumption ranges from 2.3 W in base mode to 6.6 W at full load.
By Camera it allows Mounting Cards microSD up to 256 GB capacity and integration with NAS and FTP systems.
Dahua IPC-HFW3241T-ZAS-27135 is a comprehensive solution for professional monitoring, combining high image quality with advanced analytical features and configuration flexibility.
