FAQ
What is AcuSense technology and how does it work
AcuSense technology uses deep learning algorithms to distinguish between human and vehicle targets, significantly reducing false alarms caused by other moving objects like animals, leaves, or shadows. This intelligent detection system focuses only on relevant security threats.
What is the difference between the DS-2CD2146G2-I and DS-2CD2146G2-ISU models
The -ISU variant includes a built-in microphone for audio recording capabilities, whilst the standard -I model provides video surveillance only. Both models share the same video specifications and AcuSense features.
What lens options are available for this camera
The camera is available with three fixed focal length options: 2.8mm (103° horizontal FOV), 4mm (83° horizontal FOV), and 6mm (53° horizontal FOV), allowing you to choose the appropriate coverage area for your specific installation requirements.
Can this camera work in complete darkness
Yes, the camera features built-in IR illumination with a range of up to 30 metres and can capture clear black and white images in complete darkness (0 Lux with IR). The DarkFighter technology also provides excellent colour imaging in low-light conditions down to 0.003 Lux.
What storage options are supported
The camera supports local storage via built-in microSD/SDHC/SDXC card slot (up to 512 GB), network storage via NAS (NFS, SMB/CIFS), and can upload recordings to FTP servers. It also supports automatic network replenishment for reliable backup.
Is this camera suitable for outdoor installation
Yes, the camera is designed for both indoor and outdoor use with IP67 water and dust resistance rating and IK10 vandal resistance rating, making it suitable for harsh weather conditions and tamper-resistant installations.
What power options are available
The camera can be powered via PoE (Power over Ethernet) 802.3af Class 3 or 12V DC power supply, with maximum power consumption of 6.5W (PoE) or 5W (12V DC).
