The CCD Sensor and Chipset
CCD is called, the electrical component that captures the light signal. The chipset is also an electrical component, which in turn, can translate the optical signal into an image. Thus, the combination of the CCD sensor and chipset allows you to get video. The addition of the CCD sensor and chipset determines the resolution of the image, so its grain quality.
This determines the minimum amount of light needed to operate your camera. Brightness is measured in lux, lux 0 corresponding to complete darkness and 50000 lux at maximum brightness. It is, therefore, essential to assess the brightness of the filming area when choosing the camera to ensure optimal image quality.
Good security offers cameras capable of filming at 0 lux, that is to say, in total darkness. Indeed, infrared cameras and day / night cameras have an intuitive system enabling them to automatically switch to night mode when the light is insufficient. Night mode is a mode that shoots in black and white.
The objectives determine the viewing angle of your cameras. They are available in several sizes to best adapt to the vision you want. They have a size of 2.5 mm to 100 mm which corresponds to an opening angle of 107 ° to 2.8 °.
Over the lens size, the greater the viewing angle is narrower and more remote areas will be filmed close and the zoom will be better. The choice of lens is essential because it can be compared to the eyes of the camera. Either the objective is to choose (box camera) it is already built into your camera, depending on the selected camera type.

Smoke detector, motion, pens, such cameras must put the look you want to make sure video surveillance discreetly.
IP cameras allow you to make high-end CCTV installations. Depending on the model, these cameras give you a picture resolution up to 5 megapixels.
The Different Technologies Security Cameras
There are currently two technologies are used for security cameras i.e. Analogue and IP, which are described below:
The cameras are connected to the recorder by cables; the recorder is connected to your box. Our cables also carry the current. It takes a camera cable.
The cameras are powered via a plug; the wireless transmitter communes with the receiver. The receiver is connected to a monitor or TV. The receiver may also be connected to a recorder.
The cameras are connected to a switch or to a network jack; the recorder is also connected to the network locally or via The Internet. The cameras can be powered via the network cable. The user connects via Intranet or Internet cameras or directly to the recorder.
The cameras are powered via an AC outlet; they have a Wi-Fi antenna to be connected to the network. The recorder is also connected with same network. The user connects via Internet cameras or directly to the recorder.
