Night vision cameras have a super-sleuth appeal and are often considered top-technology cameras. Many homeowners and businesses choose this option because of the camera’s obvious advantages. There are, however, some disadvantages that should also be noted before spending the extra cash for this type of security camera.
How Infrared Cameras Work
Infrared works by using low-frequency infrared wavelengths, undetectable to the human eye. These wavelengths resemble heat more than they do light and infrared cameras are sensitive to these thermal-like wavelengths. The camera amplifies the heat waves and converts them into a digital image.
When detecting images in low-level or non-existent light, the camera will produce those images in either green or black and white, depending on the type of camera you choose. During the day, however, pictures are in color. Both day and night images are clear and easy to discern.
Advantages to Buying an Infrared Security Camera
The most obvious advantage to buying an infrared security camera is the night imaging capabilities. You have the safety and security of knowing that, no matter what time of day it is, no matter how dark it is, you can always see who or what is on the premises.
Another advantage is that many night vision cameras come with motion sensors. This prevents unnecessary electricity use and DVR recording. It also ensures that, when motion is detected, you will know exactly what is happening outside.
In most cases, night vision cameras are also wireless devices. This provides you with easy installation. It can also provide you with access to your video monitoring via cell phone, computer or iPad, if you install the appropriate software and buy the right device.
Disadvantages to Buying an Infrared Security Camera
The most notable disadvantage to buying an infrared security camera is the cost. These security cameras are generally much more expensive than a simple day/night camera. If, however, your security needs meet the criteria for buying a night vision camera, the extra cost may be supported.
Another disadvantage is that infrared cameras, while not detectable by humans, do put off light that is detectable to bugs. This can attract bugs and disrupt the image. You may also find that regular cleaning is necessary to get rid of spider webs.
Frequency interference is yet another complication often experienced with infrared cameras. Because they are usually wireless, digital devices like cellular phones and even common household items like microwaves can interfere with the camera’s signal. This can be extremely frustrating for some infrared camera owners.
Other Important Factors to be Aware of
Not all infrared cameras are created equally. Low lux infrared cameras are able to ‘see’ in less light. Higher lux cameras will provide a lower quality image in less lighting. Night viewing distance is another variable with infrared cameras. Life expectancy can also vary greatly from one camera manufacturer to the next. Taking the time to educate yourself on the type of camera you are buying and whom you are purchasing it from can help you avoid the all-to-common buyer’s remorse.
Another really important factor to consider is where you will be placing the camera. While this isn’t a factor that will determine whether or not you should buy the infrared camera, it will help you determine which infrared camera is best suited for your needs.
Not all infrared cameras can be used in an outdoor setting. Protective housing is used to construct outdoor infrared cameras and placing an indoor camera out in the elements will cause your camera system to malfunction or stop working altogether. This will not be covered under warranty, since you did not follow installation instructions. Before you buy, make sure you are choosing the right camera for your needs.
Is the Cost Worth the Camera?
Deciding whether or not an infrared security camera is worth the cost is really a personal choice. While the advantages often outweigh the costs for many individuals, others find that the disadvantages steer them in the direction of another security camera option. Carefully consider your security needs and your budget before making a commitment to buying an infrared security camera.
Don’t Forget Tech Support
Many infrared security camera owners opt for the tech support, and for good reason. With a camera this technologically advanced, it is important to have someone there to help you with camera problems when you need it. While it is not an essential item, it is definitely an added benefit that can pay for itself, even if you only use it once.
A Lower-Cost Option
Still not sure if an infrared camera is right for you? Not sure if the cost is worth the trouble? Try adding some extra lighting to your monitoring area and opt for a black and white camera. Black and white cameras need less light to function than color and they are more affordable than night vision cameras, even when you add in the cost of the extra lighting.
