TP-LINK VIGI C340I(4MM) 4MP OUTDOOR IR BULLET NETWORK KAMERA

Characteristics of the device.

Where the product can be placed e.g. indoor/outdoor, horizontal/vertical.

The technology that enables connectivity of the device, e.g. wired or wireless.

The shape or design of the product.

Type of mounting e.g. wall mounting.

The colour e.g. red, blue, green, black, white.

What the casing of the product is made of.

The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".

Also known as light sensitivity, this is the smallest amount of light needed for the camera to produce an image of useable quality.

Determines the length of time the shutter lets light pass through the lens to the CCD. Shutter speed and aperture together determine exposure.

Optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications e.g. lamps that turn on automatically in response to darkness. Optical sensors come in many sizes.

Also referred to as noninterlaced scanning, this is a way of displaying, storing, or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to interlaced video used in traditional analog television systems where only the odd lines, then the even lines of each frame (each image called a video field) are drawn alternately.Progressive scan is used for DVDs and HDTV (high defintion television).

A sensor is a convertor than measures a physical quality (light, temperature etc.) and displays this electronically on a device.

The number of lenses installed in the device.

Night vision is technology which allows you to see in low light conditions.

The maximum number of pixels that can be displayed in the image. It is usually quoted as width × height,: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels.

A megapixel (MP or Mpx) is one million pixels, and is a term used not only for the number of pixels in an image, but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays. For example, a camera that makes a 2048 × 1536 pixel image typically uses a few extra rows and columns of sensor elements and is commonly said to have "3.2 megapixels" or "3.4 megapixels", depending on whether the number reported is the "effective" or the "total" pixel count (as opposed to the 2048 × 1536 = 3,145,728 finished image pixels).

The graphic resolutions that can be displayed by the device. The graphic resolution describes the width and height dimensions of a display, such as a computer monitor, measured in pixels.

The video modes that can be displayed by the device.
