For many companies, security needs to be on alert 24 hours a day. Retail outlets, for example, never know when someone may be trying to shoplift from their stores, and with a high amount of traffic, they need to have security cameras that are always on alert, able to catch the perpetrator in action. For them, the security camera is about constantly monitoring those that are going to be coming in and out, looking through the lawful people in order to find lawbreakers.
But not everyone has this type of traffic. Some people are trying to keep an eye on areas of the home or business that rarely, if ever, have visitors. If anyone is seen inside of these areas, chances are they are looking to take some important possessions.
Motion Detection with Live Warning CCTV
For these types of people, it may be best to get a motion detector security camera, specifically a one with live warning option. If you already own CCTV system there are companies that offer software solution for aftermarket installation of the live warning option. What’s special about this feature is that recognizes any predetermined objects like people or changes in the scenery and when triggered it alerts the security control center. From there they can issue live audio warnings to the intruder, which has proven to be an efficient technique. The plus side is that motion detector cameras will be able to save energy when it is not needed, and will not create a great deal a lot of files on an empty room. The advancement in technology has led to great precision in object recognition so the motion detectors turn on only when it is likely that someone has entered into the area uninvited.
Types of Motion Detector Cameras suitable for Remote Live Warning
● Infrared Motion Detector
Infrared cameras are designed to turn on as soon as there is anything that stimulates its sensor. The most common is when a person or persons moves within the infrared camera’s spectrum, resulting in a change in radiation that ultimately turns the camera on and starts recording. These are best in areas of no or little lighting, and are able to capture images fairly well, often without the intruder’s knowledge.
● Ultrasonic Motion Detectors
Unlike infrared cameras, which respond to radiation, the ultrasonic detectors send out small, inaudible pulses that bounce back to the camera, letting it know that something has changed and that someone or something has entered the room. The main problem with these cameras is that they are too precise – and thus will turn on when there is something simple blocking the path of the ultrasonic pulses, such as a box or even a kitten. They are best in empty rooms, which may not be ideal for your uses.
● Microwave Motion Detectors
Similar to the ultrasonic devices, these cameras tend to be too sensitive to changes inside a room. You need the camera to turn on when there are human being intruders, and not simply when the landscape has changed due to something disrupting the waves. Microwave motion detector security cameras send out small waves into a room in order to generate a response. Still, though they suffer from the same problems as ultrasonic devices, they do tend to be more reliable.
Each of these types of security cameras can be useful for watching your home or business. However, infrared cameras currently have the least problems with regard to turning on prematurely, and thus wasting energy and data. There are also several hybrid machines that work more effectively – combining the sensitivity of the microwave or ultrasonic with the reliability of the infrared. These devices are better at discerning real threats, but may also be more expensive.
