Both of these new, and affordable, analogue cameras offer higher resolution and ultra low illumination, which instantly make them extremely competitive in overall analog camera market.
Developed by Hikvision, the DIS (digital image system) series boasts advanced features, such as image quality, power consumption, and greater overall system stability. Features such as these are helping Hikvision reinvent how customers view analogue technology.
Additionally, both cameras in the DIS family feature a 1/3” DIS image sensor with 600TVL ultra-high horizontal resolution. Compared with conventional analog cameras, which only offer 480 / 540 TVL horizontal resolution, these new cameras provide higher video quality and improved image detail.
These units employ a vari-focal lens, which benefits users by allowing easier focusing without requiring any movement in the initial camera set-up. Moreover, the 2 cameras incorporate excellent low-light performance with a minimum illumination of 0.1Lux @ F1.2 (with AGC on) and 0 Lux with IR. 
Armed with this advantage, they are able to deliver superb quality images for objects within 40 meters (131 feet) under low-light conditions or even in total darkness.
The DS-2CE1582P(N)-VFIR3 and DS-2CE5582P(N)-VFIR3 can handle -40 degree C to 60 °C without an external heater and have a current draw of 4W (6.5W with IR cut filter on). A IP66-rated housing additionally protects the cameras from external elements, such as rain or dusty environments.
