Home Security Camera Resolution Call for Price 800.955.5201
Home security cameras can come in many different shapes and size to choose from, but all have the same reason as to why they are installed… and that is to help capture or deter criminal of suspicious activity from occurring around your home, businesses, or personal possessions. There are many key features that are necessary to ensure the camera is able to capture what is needed when crime happens, but one of the most important key features is the camera resolution rate. But what is camera resolution?
Home security camera resolution is the clearness and clarity of the image quality that is taken when the camera is recording. This is an important key feature that should be taken into consideration when purchasing a home security system or security camera because it will help determine the clearness of the image that may make the slightest different when it comes to identifying an individual that has committed a crime.
The resolution rate of a home security system is usually indicated or measured by the number of horizontal TV lines that help to produce a picture. Each TV line is generally made from numerous pixels with the total TV line amount making a full viewing picture that can be seen on your monitor. Usually the more lines the resolution rate has, the clearer the image will be viewed on the screen. Standard resolution is usually rated between 300 to 400 TV lines. This resolution rate usually offers a fairly clear image that can be viewed without too much concern. Although with faraway objects or individuals, this resolution may cause difficulties in identifying the criminal depending on the angle, distance, and light level that the image has been taken with. High resolution generally works between 400 to 600 or more TV lines. Viewing images recorded with these resolution rates can drastically increase your chances of identifying a criminal due to the clearness and clarity it produces. The higher the resolution rate is the better your imagery will become.
To ensure that the camera resolution will be used to its maximum potential, it is recommended that other security devices and equipment that will be connected to the camera feature a high resolution rate as well otherwise the image quality may be jeopardized. For example: if you have a 480TV line home security camera system, a 500 TV line monitor, and a 300TV line resolution time lapse security recorder, you will most likely receiver a great looking picture on the monitor screen when viewing it live, but a lower quality video when you playback recorded footage. The reason why this is, is because the time lapse security recorder is only the standard resolution of 300 TV lines which is lower than that of the 480TV lines of the security camera. When the recorder is recording it will only record with 300TV lines of resolution instead of the high resolution that the camera is set at. The reason why the pictures are clearer on the monitor is because the monitor resolution is 500TV lines which are even higher than that of the camera, therefore it produces clearer images for quality viewing.
Choosing a camera with a high resolution rate is important, but to ensure that it is going to function in the area where it will be placed you may also need to consider a few things. For example a high resolution camera although can be beneficial in highly lit locations, may not be able to be used in low light and dark environments without the help of night vision properties. Placing a high resolution camera into a dark environment without low light technology can be rendered useless because it won’t be able to record anything but darkness. For night vision recording with a high resolution camera it is good to check the camera for night vision properties or a low lux rating. A lux rating is the lumen per square meter and is usually measure by the intensity of light that passes or hits a surface of an object as it is perceived by the human eye. This rating when zero or close to zero is able to help the camera see in completely dark environments.
The lux rating combined with a high resolution camera can produce a well adaptive and powerful home camera system that can produce clear and detailed images in dark environments to help capture and identify criminal activity. Most low light cameras are classed as day/night camera systems because they record with color during the day then are able to switch to black and white when the light levels begin to fade. These are generally used as a round the clock 24/7 surveillance system that can protect your possessions, property, and business at all hours of the night from vandalism, theft, and criminal activity.
Over all when looking to choose a home security camera that is suitable for your location and application, it is important to take into heavy consideration of the TV line resolution rate that the camera and security equipment is integrated with. Choosing carefully you can easily purchase not only a fully functioning and well adaptive home security camera system, but a reliable camera system that can help to identify criminals in all kinds of lighting conditions.
