Hikvision DS-2CD3646G2T-LIDZSU/4G/SL(256G)(1T) 4 MP Darkfighter S Smart Hybrid Light Motorized 4G Varifocal Bullet Network Camera
This 4 MP motorized varifocal bullet camera combines mobile networking with smart hybrid illumination, human and vehicle target analysis, and audible and flashing-light warnings. It supports the HEOP open platform and memory card recording; documented configurations remain separate options. Hikvision specifies powered-by-DarkFighter technology for low-light imaging.
Product description
The camera delivers a maximum resolution of 2688 × 1520. Image processing includes 120 dB WDR, BLC, HLC, 3D DNR and defog.
The motorized varifocal lens provides a focal range of 2.7 to 13.5 mm. Supplemental illumination uses infrared and white light, with a stated range of up to 60 m and smart supplemental lighting support.
Perimeter protection covers line crossing, intrusion, region entrance and region exit events. Alarms can be triggered by specified human or vehicle target types. Face capture and people counting functions are also available. Event linkage also supports audible warnings and flashing-light alerts.
The main stream supports H.265, H.264, H.264+ and H.265+ compression. The built-in card slot supports microSD/microSDHC/microSDXC cards with capacities up to 512 GB. Built-in microphones and line-level audio input and output are provided. A built-in speaker is also included. Mobile connectivity uses LTE-FDD and LTE-TDD standards and supports a Micro SIM card; frequency bands differ between the EU and LA options.
The enclosure is specified with IP67 protection against water and dust. Power is specified as 12 VDC, with a maximum consumption of 15 W and reverse polarity protection.
