Digital Night Vision is a fairly new technology that was introduced to the market within the last decade. Similar to other passive night vision devices, Digital NV allows users to view images in near-total darkness. The two main benefits of Digital Night Vision include an ability to work during daytime or nighttime without risking damage to the device, as well as real-time High Resolution Recording Capabilities in standard North American NTSC video format or European PAL video format. However, recording capability is not available on all models.
In terms of performance, some higher-end Digital NV systems can be compared to Gen 2 NVD, while the majority of low-end systems can are comparable to Gen 1. Use of powerful IR Illuminators drastically increases performance and viewing distances of Digital Night Vision Devices.
Digital Night Vision technology is very different from conventional I2 night vision. The light enters the device through an objective lens, after which it is processed through a highly sensitive, charged coupling device (CCD), and then sent to a Liquid Crystal Display (LCD) where the image is displayed.
Digital vs Image Intensified Tube Solutions:
- Unlike an Intensifier tube, digital night vision devices do not have to worry about exposure to bright light. Even though today most systems have bright light protection, still long exposure to bright light will damage an intensifier tube. These issues simply do not exist in the digital products.
- Majority of digital systems offer the ability to adjust brightness levels according to your need. Most Intensified systems do not offer that ability.
- Many of the digital systems offer various ways to record what you see. While that is also possible with Image Intensified systems, the interface is much more cumbersome requiring additional camera equipment that is attached via camera adapter to the night vision device.
