Video cameras are a broad topic. Today’s technology has advanced vastly from the analog CCTV systems that everyday business owners are used to. In this article we are going to discuss the following features video cameras can offer:
- Smart IR
- Turbo HD
Smart IR Video Cameras
Have you ever looked over footage on video cameras, and there was a white face? The face was so white you couldn’t tell who they were. This was and still is a common issue with video cameras. White faces occur because a person gets too close to the IR LEDs of the night vision camera. This occurs even when the video camera is recording a 65 foot IR range. If a person can approach the camera this issue is going to occur.
Smart IR solves this white face dilemma by automatically adjusting the video camera’s intensity of the infrared LEDs when an object approaches. Smart IR technology is built right into a video camera. This feature is unfortunately not an attachment or software update for existing cameras. The Smart IR feature has become crucial for almost every business owner who wants night video surveillance because it makes catching criminals so much easier.

Turbo HD Video Cameras
Turbo HD cameras provide high-definition megapixel video. I know what you are thinking. Why is this special? Turbo HD supports up to 1080p resolution at distances over 1500 feet, has immunity to electromagnetic interference, live video can be view in high resolution with zero latency because the stream is uncompressed, and has Bi-directional signalling that allows for PTZ control and setting camera functions remotely.
Previous HD video over coax methods have continuously struggled with these features. They have been just plain out unreliable due to distance and lack of bi-directional communications. That’s what make Turbo HD so innovative because it solves so many issues old cameras were having.
Hikvision does a great job at explaining this concept watch the following video for a visual explanation: https://www.youtube.com/watch?v=tCXmWl0AJdY
WDR Video Cameras
Also known as “Wide Dynamic Range”. WDR cameras have special software that allows them to balance lighting into one clear image. This alleviates dark spots in the video and shows more vivid details. Many cameras have trouble recording underexposed and overexposed images because they are designed to record the middle area of light between very dark and very bright.
WDR uses tone mapping which lets the camera automatically brightens dare areas and darkens light areas. The software can also capture several images of the scene at different exposure levels. This allows the video camera to collect identical images both underexposed and overexposed and to take the best parts of each image.
IR Video Cameras
IR cameras sense infrared energy (heat) and converts it into an electronic signal. This electronic signal is then processed to produce an image on a video monitor and to preform temperature calculations. IR cameras allow you to monitor thermal performance.
