Home security cameras come in various shapes and sizes to suit different needs and pockets. There are, amongst others, indoor cameras, outdoor cameras, hidden cameras, those with motion sensors and night vision and also full surveillance systems complete with a DVR kit.
For a variety of reasons hidden cameras are rapidly gaining in popularity in the home surveillance field. These small cameras can be hidden in everyday objects such as toys or radios, they can be fixed to a wall, or they can simply be placed in an area where they will not be noticed easily. If you want to keep track of what your babysitter is doing while she’s supposed to watch the baby, this is the ideal way to do it.
The majority of people, however, use surveillance units for safety and security purposes. For this reason they are more often used outdoors than indoors. Most of these kinds of cameras are nowadays fitted with built-in night vision for better vision in low or no light situations. This makes for very effective surveillance without having to pay a small fortune to a professional surveillance service.
Motion sensor cameras are ideal for security purposes. This type of camera makes use of an infrared light pattern. Every human being emits infrared energy and the camera can pick up this as soon as a human body enters its range. This can either trigger an alarm, or switch on floodlights to scare off intruders.
Night vision security cameras also make use of the infrared light principle. They don’t trigger an alarm or switch on a light, but rather emit invisible light that will illuminate an intruder – even in total darkness! Do not confuse these types of cameras with thermal cameras that use radiated heat signatures to produce images. Infrared security cameras use an array of LEDs to produce invisible light that reflects off objects onto the cameras sensor to produce an image.
You can also buy surveillance cameras in kit form. Depending on your needs, you should buy a kit with one or multiple cameras. Most of these kits also come complete with a DVR for recording the images. This is very handy if you can’t watch the camera all the time. The images can then be stored and watched whenever you have time.
You shouldn’t buy home security cameras solely based on their price. First sit down and make an assessment of your own needs. Then look at a number of cameras that will satisfy those needs. Once you have a shortlist of cameras that will all do the job that you want them to do, you can make your final decision based on valued for money.
