Factors that determine field of view
When it comes to wireless video monitors, the field of view is an important factor to consider. The field of view refers to the area that can be captured by the camera and displayed on the monitor. Several factors come into play when determining the field of view for wireless video monitors.
Camera lens
The type of lens used in a wireless video monitor can greatly affect the field of view. Wide-angle lenses, for example, have a broader field of view and can capture more of the surrounding area. On the other hand, telephoto lenses have a narrower field of view and are more suitable for zooming in on specific subjects.
Sensor size
The sensor size of a wireless video monitor also plays a role in determining the field of view. Cameras with larger sensors can capture more detail and therefore have a wider field of view. Smaller sensors, on the other hand, may result in a narrower field of view.
Distance from the subject
The distance between the camera and the subject being monitored can affect the field of view. The closer the camera is to the subject, the narrower the field of view will be. Conversely, if the camera is further away, the field of view will be wider and capture more of the surrounding area.
Zoom capabilities
Some wireless video monitors have zoom capabilities, which can affect the field of view. Cameras with a high zoom capability can narrow in on specific subjects, resulting in a narrower field of view. On the other hand, cameras with no or limited zoom capabilities will have a wider field of view.
Aspect ratio
The aspect ratio of the monitor can also influence the field of view. Most wireless video monitors have either a 4:3 or 16:9 aspect ratio. A monitor with a 4:3 aspect ratio will have a slightly narrower field of view compared to a monitor with a 16:9 aspect ratio.
Field of view measurements
When discussing field of view, there are three common measurements used: horizontal field of view, vertical field of view, and diagonal field of view.
Horizontal field of view
The horizontal field of view refers to the width of the area that can be captured by the camera and displayed on the monitor. It is measured in degrees and represents the side-to-side perspective.
Vertical field of view
The vertical field of view, on the other hand, represents the height of the area that can be captured by the camera. It is also measured in degrees and determines the top-to-bottom perspective.
Diagonal field of view
The diagonal field of view takes into account both the horizontal and vertical measurements and provides a diagonal perspective of the area that can be captured. It is also measured in degrees.
By considering all three measurements, the field of view of a wireless video monitor can be accurately determined and assessed.
Common field of view ranges
Wireless video monitors can offer different field of view ranges to cater to various needs and preferences. Here are the common ranges you can expect to find:
Wide-angle: 100 degrees or more
Wide-angle field of view is ideal for capturing a larger area or room. It allows for a broad perspective and is often found in surveillance cameras or monitors used in large open spaces.
Standard: 50-70 degrees
A standard field of view is suitable for general monitoring purposes. It provides a balanced perspective and is commonly seen in home security cameras or video baby monitors.
Telephoto: below 50 degrees
Telephoto lenses offer a narrower field of view, making them suitable for focusing on specific subjects or areas of interest. This range is often used in surveillance or action cameras to capture detailed footage.
Impact of field of view on monitoring
Understanding the impact of field of view is crucial in choosing the right wireless video monitor for your specific monitoring needs. Here are some common applications where field of view plays a significant role:
Surveillance applications
In surveillance applications, a wider field of view is generally preferred to capture a larger area and monitor activities more efficiently. Wide-angle lenses are commonly used to cover more ground and minimize blind spots.
Baby monitors
When it comes to baby monitors, a standard field of view is typically sufficient. It allows parents to keep an eye on their baby’s crib or room without capturing unnecessary areas.
Pet monitoring
For pet owners who want to keep an eye on their furry friends, a wider field of view can be beneficial. It allows for better coverage of the room, ensuring that no area is left unmonitored.
Home security
In home security applications, the field of view depends on various factors such as the size of the property and the desired level of monitoring. Wide-angle lenses are often used to cover larger areas, while narrower fields of view may be preferred for focusing on specific entry points or vulnerable areas.

Field of view and video monitor types
Different types of wireless video monitors are available in the market, catering to specific monitoring needs. Here is a breakdown of how field of view relates to various types of video monitors:
Security cameras
Security cameras require a wider field of view to effectively monitor large areas. Many security cameras offer wide-angle lenses to capture a broader perspective and minimize blind spots.
Webcams
Webcams generally have a standard field of view, suitable for video conferencing or capturing the immediate surroundings of a computer or laptop. While some webcams may have a wider field of view, most tend to focus on providing a balanced perspective for close-range monitoring.
Action cameras
Action cameras are designed for capturing fast-paced activities and adventures. They typically have a narrow field of view to provide maximum detail on the subject being recorded.
Video baby monitors
Video baby monitors often aim for a balance between capturing the entire crib or room and providing a clear view of the baby. A standard field of view is commonly used to achieve this balance and ensure that parents can easily monitor their little ones.
Factors affecting field of view performance
In addition to the various factors that determine the field of view, there are several other elements that can impact the overall performance and quality of the viewing experience:
Image distortion
Some cameras and monitors may experience image distortion at the edges of the field of view. This can result in a slight fish-eye effect or stretching of the image. It’s important to choose a camera and monitor combination that minimizes image distortion for a more accurate representation of the captured area.
