The best night vision security cameras can provide clear pictures of at least 1080p quality, even in low light conditions, you can easily recognize the face and license plate number. These cameras use infrared light from the stars and moon to enhance night vision. Some use sophisticated sensors to provide high definition within 150 feet or more. They also have convenient user features, such as two-way calls, which allow you to interact with visitors and family members. These security cameras can save up to one month of recordings on an SD card or through subscription-based cloud services.
If you want to improve the security inside or outside your house, read on to learn about the features you should consider when buying one of these surveillance devices, and understand why the camera below can reduce costs.
When looking for a camera that can enhance property security, it is important to consider many factors, including the environment in which the camera will operate, the field of view, and the complexity of the installation.
The environment in which the camera will operate has a major impact on the type of camera you should choose. If your camera is performing tasks outdoors, it must be durable enough to withstand rain, snow and high winds. You also need to protect the lens to prevent water droplets, ice or snow from covering the lens and distorting the image.
If the camera is installed in a lower area, it may be easily damaged or tampered with. In this case, please consider the impact rating of the camera. You should also consider the size of the area to be monitored to determine the angle the camera should have, or whether multiple cameras are needed to cover the area.
The night vision camera will record in color or black and white. Traditional night vision cameras use infrared filters, which can “cut” the camera from color to black and white in the dark or low light to produce higher quality night images.
In the past, if you want to obtain color images at night, you need to add enough lighting in the form of spotlights or floodlights, which basically turns night into daytime, thereby defeating the purpose of night vision. With the latest innovations in low-beam technology and image sensors, some cameras can produce color images even in weak lighting conditions, even without a spotlight.
The camera can be battery powered or connected to a power source. The fully wireless camera is easier to install, and the camera can be installed in the home without complicated wiring. They are connected via Wi-Fi, allowing you to view the stored material from your smartphone. Many people also use virtual assistants, such as Google Assistant and Amazon Alexa.
Although wireless makes installation easy, it also means that the camera is dominated by bandwidth. If the bandwidth is blocked due to excessive usage nearby, or does not work properly due to signal interference between the camera and the router, the 1080p camera will drop to low-quality 720p. Wireless cameras also need to replace the battery regularly to prevent operational errors, which can be troublesome.
The wired system eliminates these two problems and ensures that your camera will not experience operating errors or video quality degradation. If you use a dedicated computer monitor and hard drive instead of Wi-Fi to watch the video, they also provide the security of a closed-circuit system and are therefore less likely to be hacked.
Due to the wiring involved, wired cameras need to be professionally installed, which increases the upfront cost. Unless you plan to use a Wi-Fi connection, you may also need to set up a dedicated computer monitor to watch the video and DVR for recording, which makes the system expensive.
When looking in the dark, there are only two resolution options: 1080p and 4K Ultra. Although 4K Ultra will be clearer, both resolution levels allow you to recognize faces and read license plates easily. The most significant difference is the scope. High-resolution 4K cameras can see up to 150 feet or more in the dark, while most (though not all) 1080p cameras have a maximum limit of 40 feet or less.
