Resolution is a measure of the number of pixels use to create a video image. The more higher the resolution of security cameras, the more detail they will be able to capture. A pixel is the tiny dot that makes up a video images.
Security cameras that has more pixels will create a sharper image of the video. High-resolution security cameras will allow a person to zoom in on the video and still capture details such as a persons face or license plate number. The higher the resolution, though, the more data the storage drive will have to take in.
Choosing the Right Security Camera Resolution and Storage
Therefore, resolution and storage is two factors that a person must consider when purchasing a security camera. There are different resolutions of security cameras that is suited to different scenarios. For instance, 720p resolution is a low resolution security camera that is used for indoor security.
Security cameras with 1080p resolution offer more detail then those with 720p resolution and are often used to monitor doorways so that a person can recognize the clothing or type of individual who come to the door from a distance of ten feet. 4-megapixel security cameras offer the most detail and are used to monitor large area like parking spots. Two 1080p cameras may be needed to monitor a given area, but only one 4-megapixel camera are needed to cover that same area.
Storage requirements for security cameras is affected by the resolution of the security camera and the recording settings. Cameras with 4K resolution require twice as much storage space each day as cameras with 1080p resolution if the cameras are recording security footage 24 hours per day. Using motion-only recording will reduce the amount of storage space that the security cameras require.
Additionally, using compression technology to reduce the size of the video files will also reduce the amount of storage space that is required for those security cameras. In order to determine the appropriate size for the storage drive for security cameras, you must calculate the total number of security cameras and the resolution of each camera. The lighting of the area that the security cameras will monitor will affect the performance of the resolution of those cameras during the night.
Security cameras with infrared lighting will allow the cameras to see in the dark by converting the recorded video images to black and white. Cameras with higher resolutions will allow the infrared lights to provide the clearest security footage of monitored areas at the most greatest distance. Color night vision uses spotlights to provide color security footage of monitored areas during the night; however, color night vision spotlights does not have the same range as infrared lights.
The resolution and lighting technologies of the security cameras must be matched to one another. Should a person choose high resolution for security cameras, but lighting technologies be poor, the quality of the recorded video will be of a low quality. It is best not to purchase a security camera with the highest possible resolution.
For instance, it is common for many individuals to purchase security cameras with an 8-megapixel resolution because these cameras have high specification. However, 8-megapixel security cameras can cause problem with the bandwidth of the security cameras network. For example, if all that is necessary is to be able to identify individuals who come to the front door, a 1080p or 4-megapixel security camera is sufficient.
For those interested in monitoring the license plates of vehicle that come to a parking spot, a 4K resolution security camera is required. Additionally, the cameras motion settings should be adjusted so that they dont record windblown branches in the monitored area. Such recording of these moving objects create unnecessary video files.
Finally, the security cameras frame rate should be checked. Cameras with a frame rate of 30 frames per second will provide the smoothest footage of the monitored area without any choppy security footage.
