One of the most important points of attention when it comes to camera security: image quality. Do you want to capture razor-sharp camera images in poor lighting conditions? Then you end up with 4K Ultra HD security cameras. In this article, we take a closer look at the features and techniques of different types of surveillance cameras.
What are the features of a 4K Ultra HD security camera?
The resolution determines the quality of camera images. Old-fashioned surveillance cameras often have a resolution of 640 x 480 pixels. These security cameras are still available and fine if there are no high demands on image quality. More modern cameras offer Full HD, 2K HD or 4K Ultra HD image quality. A security camera with Full HD provides images of 1920 x 1080 pixels, while Ultra HD provides an image of 3840 x 2160 pixels. More pixels means a sharper image!
Construction of the 4K Ultra HD image
Camera images are made up of pixels, which are colored dots. All pixels together form the image. The more pixels, the clearer the image will be. 4K pixels are relatively smaller, so you can better recognize faces and objects. In addition, with these types of security cameras it is possible to zoom in further in the image without immediately seeing a loss of quality.
4K Ultra HD camera images as evidence
Security cameras are used to monitor. If there is a burglary or other crime, it is important to identify the perpetrator as quickly as possible. Camera images can also serve as evidence in a court case. However, this is only possible when a perpetrator is clearly visible. Security cameras with a low resolution do not provide enough sharpness to recognize someone. At twilight or in the evening hours, people are barely or not at all recognizable. That is of course a shame!
Advantages of a 4K Ultra HD security camera
4K Ultra HD cameras are equipped with a light-sensitive lens. This way, a camera can continue to film in color for much longer, even when it starts to get dark or dusk. In the dark, your camera images are almost as clear as images taken during the day. Of course, in addition to the image quality, this also depends on the other technologies used. Pay particular attention to the range, a camera with strong SMD LEDs allows night vision up to 60 meters.
With 4K Ultra HD surveillance, more is required of the processor in a camera or recording system and more data may also be sent over the network. Fortunately, internet connections and recording systems are increasingly equipped for this. 4K surveillance cameras from Sitcon.nl work with an HD NVR recorder and can be connected to a PC or laptop. With the help of an app it is even possible to view images live via the smartphone.
Is Ultra HD 4K better than Full HD?
There is a substantial difference between 4K Ultra HD and Full HD. This difference is clearly visible on a large screen and Ultra HD images are also significantly sharper on a smaller screen. A Full HD security camera is not necessarily worse. You can take excellent pictures in clear weather or with sufficient light. By the way, did you know that the 'p' in 1080p stands for 'progressive'? This means that all 1080 lines are refreshed separately from top to bottom. This gives better image quality than 1080i. Is surveillance or supervision an important point of attention? Then it is best to opt for Ultra HD camera surveillance. Imagine an incident or crime taking place in your business or home. In the case of camera surveillance, the perpetrator is then captured with surveillance cameras. However, the images can only serve as evidence if the incident and the associated faces are clearly visible. In all other cases, the identity and events remain guesswork. To prevent this, choose 4K Ultra HD security cameras.
What does a 4K Ultra HD security camera cost?
When you choose the best of the best, there is of course a price tag. Partly due to improved technologies, 4K camera security is more expensive than traditional camera security. View our range of Ultra HD cameras below to orientate yourself on the price of an Ultra HD camera.
