Choosing Between A Monochrome and a Color Night Vision Security Camera

Choosing Between A Monochrome and a Color Night Vision Security Camera

A security-light camera with built-in camera and recording device will usually work, right? But to record video, a security light with video output doesn't always mean you'll be able to see very far into the distance, and a security light alone doesn't necessarily mean better night vision either. In fact, even if your security light has both a video input and an audio input, the resulting picture might not be very clear or even recognizable, because the light intensity varies with distance. So while a security light camera with a built-in DVR and audio recorders will probably record everything for you, they won't always do so at the highest quality. There are cameras that have separate audio circuits, which can capture audio at a much higher volume than a single-circuit camera.

The problem with relying on security cameras to help you in your home is that they are designed only to detect movement, such as a person walking towards your house. Thus, security lights and DVR cameras are great for deterring burglars, but their limitations leave room for improvement. You should know about the various options available for motion detection in security cameras. Here's what you should look for.

 

- ARM processors. Some security cameras use Arm & Hammer sensors, which are based on the ARGUS 2 algorithm, originally developed by NASA. This algorithm is still in use in some commercial and military applications but is widely used in security lights and DVRs, because it is sensitive enough to catch even slight movements. The advantage of using an ARM processor is that they are more compact than true ARM processors, which also means that they are easier to install, and because they use less power, they are cheaper to run.

- Starlight sensitive LED. This type of Argus 2 camera is ideal for use in home security cameras and outdoor floodlight systems. It uses a unique photo resistor to determine the intensity of light, which passes through the camera lens. The result is an incredibly bright light, which can be seen from hundreds of meters away. However, this type of light is sensitive to the dimmer light, so it isn't useful for spot lighting in most cases.

 

- Light Emitting Diode or LED. The LID is still an active research project, but many security cameras use a standard LED instead. These are much brighter and have a much longer life than the previous type. Still, they tend to last only for a few months before needing to be replaced, so they are not a great alternative for motion activated security lights. In addition, the amount of light emitted by an LED is limited, which makes them unsuitable for use in spotlights or outdoor floodlights.

 

- Light Sensitive Elements. Most security lights today use a metallic sensor called a photovoltaic array. This array absorbs photons from the light, which is then detected by an internal microchip within the camera. If there is no photo, the sensor will not turn on, thus effectively turning off the security lights. There are also elements available that allow live view, allowing people at the site to see what is happening via a monitor.

 

Live view security cameras use a wide range of electrical devices and microprocessors to capture live video images. These devices are very sensitive to changes in light, which means they must always remain in a well-lit room. Many professional security cameras also use daylight resistant or low light sensors, which give them even greater night vision capabilities. There are other, less sophisticated security cameras that may be used in combination with these type of devices, however.

 

Overall, a color night vision camera offers the highest level of picture quality possible for your needs. These cameras also have many additional benefits over their monochromatic counterparts. For example, a color camera's image processing software offers superior color accuracy than any other option, improving your night-vision capabilities. Also, most color night vision cameras have higher levels of lens durability and weather-proof, meaning that you are less likely to need to take the unit out of service during severe weather. These and other benefits make color cameras a great choice for security-light monitoring.
