PRODUCT DETAILS
The Hikvision DS-2CD3646G2T-IZSY is a 4 Megapixel bullet IP camera with a 2.7-13.5mm motorised zoom lens and features Acusense technology which helps reduce false alarms by differentiating between humans and other triggers such as animals or branches. Powered-by-DarkFighter technology provides an incredibly clear picture, even in ultra-low light conditions and the 120dB WDR provides controls the exposure and balances the picture in any light condition. The camera can be powered either with a 12 VDC power supply of directly through the Ethernet cable (PoE).
Deep Learning with AcuSense Technology

The most common concerns in perimeter protection are trespassing and vehicle break-ins. AcuSense helps you to focus on these events in two ways
- Alarm will only trigger when the preset intrusion type takes place
- Related videos are sorted by categories for easier search
Users can focus on alarms triggered by humans and vehicles while false alarms triggered by small animals or other irrelevant objects are vastly reduced

Powered-by-Darkfighter Low Light Technology
Alongside the AcuSense deep learning capabilities, the DS-2CD3646G2T-IZSY is complimented by Hikvisions 'Powered-by-Darkfighter' technology. This allows the camera to stay in colour mode for longer in low light conditions. When small details matter, such as the colour of an intruder's clothes, Darkfighter allows for more detailed surveillance for longer periods.

DORI - Recommended operational range of the camera
DORI is a standardized system that provides a clear framework for evaluating the effectiveness of CCTV cameras. It is based on the European standard EN 62676-4, which defines specific criteria for detecting, observing, recognizing, and identifying objects or individuals within a camera's field of view. For more information on understanding the DORI metrics, please read our blog article here.
The DORI specifications for this camera are:
Wide: Detection: 64m, Observation: 25m, Recognition: 12m, Identification: 6m
