Night Vision Cameras

There are a number of different types of night vision cameras available. Here are some of the night vision cameras that may be purchased:

Outdoor night vision surveillance camera- This camera is used to film an area and capture anything that happens in the area on footage. The film may also be viewed on a screen, so that people can see what is happening in the area, even during the dark.

Motion sensor cameras- These cameras will start recording when they detect motion. This eliminates the need for large periods of recording as it only records when there is something to watch.

Vandal proof night cameras- These cameras are specially designed to prevent being ruined by vandals. They are mainly used in camera night surveillance vision.

Day night color cameras- These cameras record in color during the day and then can record using night vision technology at night.

Infrared night cameras- These cameras have camera infrared night vision technology to allow filming even when there is no light available.

Mobile spy night cameras- These cameras are mobile so that they can be placed anywhere you want to film. The night vision means that you can film what people are doing in any darkened area.

How Do Night Vision Cameras Work?

Spectral Range

Humans as a species have very poor night vision, especially compared to other mammals. The eyes can only process a small portion of the electromagnetic spectrum, which is the measurement of all electromagnetic radiation. To put it simply, human eyes can only see a very small percentage (called visible light) of what is actually going on all around them. Cameras have the ability to open up and expose to more of the electromagnetic spectrum than human eyes can process. This feature allows cameras to be used a night, in conditions of low to no light. The camera uses a series of filters to go from recording only visible light (so the images taken look like what people see) to a wider range on the spectrum. This is normally accompanied by the photo or video having a green hue, as the camera is recording more light than humans can see.

Intensity Range

Another simpler way that some cameras record in night vision is to enhance their intensity range. This means that the cameras are enhancing the quality of available light through a variety of processes. Camera features like using an image intensifier, which captures light for longer periods of time than normal, gain multiplication, which changes the way images are exposed. The use of highly sensitive photo detectors all enable cameras to expose proper looking images under conditions of low light.

Night Vision Camera

Here is a guide on how to choose the right night vision camera for your home or business. We are going to cover what suits your best needs and how to pick the right camera. Security cameras were use to be limited to businesses and major corporations, but that has all changed in the past decade or so with the reduce cost of goods and so forth.

1. Before buying a night vision security camera, it is important to study what your needs are for your security system. Meaning that you have to consider the area that needs to be covered and the number of cameras needed to protect your home or business.

2. Sometime you might need to record audio but it might be illegal to do so in your state, please check with local and state laws before considering getting a security system with a microphone. Cameras with mics built in is a very useful tool when you want to fully document everything that is going on in your home or business.

3. To save on cost, sometimes it is not necessary to buy all weatherproof night vision cameras. You can always get weatherproof night vision cameras for outdoors. Weatherproof cameras housing are meant to protect your cameras for the elements such as wind, snow, rain, the hot sun and so forth. For indoor use, it is not necessary to use weatherproof cameras because it is in a controlled environment. Generally weatherproof cameras cost more then dome or box cameras. It would be best to use dome/ box cameras for indoors.

4. The next point to consider when choosing security cameras is the location of the cameras. If the location is hard to wire, then it is better to choose a wireless security camera system. But you might get interference with a wireless system, but here are some tips to reduce the interference.

Mount the receiver as high as possible in your home or business.
Make transmitter to receiver as clear of obstructions as possible.
Steel or aluminum siding can greatly reduce range of transmitter to receiver range.
