Hikvision, the video product manufacturers, recently unveiled a new series of surveillance cameras – DS-2DF5274 1.3MP Network Speed Dome Camera and DS-2DF5284 2MP Network Speed Dome. They are aimed at airports, industrial parks, harbours, and any large area requiring PTZ CCTV.
The models are true day-night cameras with an infra-red cut filter and are capable of a one-third-inch progressive scan, works in low light and, with 3D DNR (Digital Noise Reduction) functionality, the images are further enhanced since it helps to reduce noise and motion blur.
The DS-2DF5274 offers a 1280×960 resolution at 25 to 30 frames per second, and a 20X optical zoom of 4.3mm to 86.0mm. It also has a zoom speed of 5s and 54.1–3.2 degree angle of view. Whilst the DS-2DF5284 is a similar camera with slightly different capabilities, gives users another option. It has an HD 1080p resolution at 25 to 30 frames per second, as well as a 20X optical zoom of 4.7 to 94mm. Its zoom speed is 2.7s with a 58.3–3.2 degree angle of view.
With a pan speed of 540 degrees per second and an endless range of 360 degrees, they can capturing the most minute activities it is claimed. As network cameras, they can be integrated in a surveillance network through an RJ45 Ethernet connection, working with other compatible network devices. The products offer dual streaming and H.264/MJPEG/MPEG4 compression to optimise bandwidth use. It even supports up to ten users at once monitoring live images at different locations. ONVIF and PSIA protocols are also supported for the integration with other equipments, to meet the requirements of different surveillance needs.
Other features include 24 programmable privacy masks, with a maximum of eight zones masked on the same video screen. These customisable zones stay in place even though the cameras are moving, which lets users block parts of the cameras’ view for privacy, without compromising their surveillance of the rest.
