Reolink Dual Lens Secuirty Camera
Dual-lens cameras improve the focusing speed and result in sharp, clear footage. This dual-lens WiFi camera features 4K resolution, wide and telephoto lenses, auto-tracking, pan and tilt and two-way audio.
It also has a revolutionary color night vision and smart detection. You can draw specific zones to protect your home and receive notifications with siren alerts if someone enters into these zones.
Video Stitching Technology
Dual-lens cameras capture video footage from two different perspectives, merging them into one seamless composite view. This enables them to capture wider areas and more detail than single-lens cameras can. Unlike digital zoom, which only decreases image quality and can lead to blurring, dual-lens technology uses optical zoom, allowing for clearer, more detailed footage.
Panoramic stitching can be considered as a re-extension of image/video stitching, whereby a sequence of images/videos are stitched together in a closed loop using multi-image stitching algorithms and projected to a cylinder or sphere to generate a 360-degree panoramic view/video. This technology is widely used in virtual reality head-mounted devices for immersive video experience.
The most commonly adopted panorama stitching methodologies include pre-calibrating intrinsic camera parameters and bundle adjustment (BA)[1], determining image/video spacing and camera rotation, generating a mapping matrix, estimating the perspective transformation, deforming and aligning the overlapping images/videos, and blending the aligned images/videos. However, such methods require restricted acquisition environments and datasets and introduce a wide range of potential flaws such as wide baseline, large parallax, changes in illumination/contrast, low texture, and occlusion.
Recently, feature-based methods have been proposed for panorama stitching. These algorithms utilize the characteristics of objects to guide image/video registration and alignment, and rely on sparse feature matching to calculate adjacency relationships between input images/videos. By Dual Lens Secuirty Camera constructing a graph, these methods are capable of efficiently updating the stitching template when objects move across the overlapping regions.
Wide Viewing Angle
One of the main advantages of dual lens cameras is that they offer a wider field of view than traditional security cameras. They use two separate lenses to see a scene from different perspectives and then combine the images into one final shot. This provides more detail and less distortion than a single-lens camera.
The Gwell ELX4IR28A Dual Vandal Dome is an excellent example of a high-quality dual-lens IP security camera. It uses twin 4 Megapixel fixed 2.8mm lenses to give you a wide and telephoto view of your space. This helps you to monitor the entire area and ensure Dual Lens Secuirty Camera that no blind spots are left. In addition to this, the camera comes with advanced software that enables you to zoom in and out without losing image quality.
Another benefit of a dual-lens security camera is that it can track a subject more accurately than single-lens models. This is because the two lenses can provide different views of a moving object and then display both the wide-angle and the zoomed-in view simultaneously in the video recording. For example, the Reolink TrackMix series of dual-lens security cameras can do this. This feature is especially useful for monitoring large outdoor areas and keeping an eye on the details that might otherwise be hard to see. In addition, the cameras come with built-in infrared LEDs that help you to see things clearly at night.
Person/Vehicle/Pet Detection
If you’re looking for a dual lens security camera that will keep you informed of what’s happening outside your home, look no further than this option. It has two lenses that combine to provide a 180-degree view of your porch, driveway, or other outdoor area. It uses motion sensors to start recording as soon as someone enters the range and will send you an alert on your smartphone. It can also trigger a siren and spotlights to deter any unwanted individuals from approaching your home.
This Reolink Duo 2 wireless security camera has a person/vehicle detection feature that will allow you to distinguish between human and vehicle movement while ignoring other forms of motion such as wind or bugs. This will save you the hassle of getting notifications every time something moves on your porch or in your yard. It also features a solar panel and rechargeable battery for an eco-friendly solution.
This eufy security camera has a 2K resolution and is capable of tracking both animal and human motion. It also has a night vision feature that activates automatically when lighting conditions become dark. The app allows you to determine the types of movement that will trigger recording and notifications. It also has a pan-and-tilt function to cover more ground. It also has a built-in speaker for two-way audio.
Power Options
Reolink Dual Lens Secuirty Cameras offer multiple power options. They can be powered via Power over Ethernet (PoE), direct current, or battery. The PoE model can also act as a network switch, eliminating the need for additional hardware. The battery-powered version is portable and ideal for outdoor use, as it reduces the amount of wire threading needed indoors.
The cameras’ onboard smart technology can accurately detect people and vehicles, so you will only receive alerts about real threats. In addition, the motion detection function allows you to customize a motion zone, removing irrelevant objects from your monitoring. You can also set the maximum size of a vehicle or person that triggers an alert. You can then use the free app or client to watch and replay videos, allowing you to save the ones that matter most for your evidence.
The camera will draw more amperage when its infrared LEDs and built-in heaters are turned on, so you need to ensure that the power supply you choose can handle its maximum power draw. If you are installing the camera in an area with long wire runs, make sure to consult the voltage drop table for cable run distances and gauge sizes that will support your system’s maximum current draw.
