Define the surveillance goal: overview or high detail
Overview images aim to view a scene in general or view the general movements of people. High detail images are important for identification of persons or objects (e.g., face or license plate recognition, point-of-sales monitoring). The surveillance goal will determine the field of view, the placement of the camera, and the type of camera/lens required. More on lens elements.

Area of coverage
For a given location, determine the number of interest areas, how much of these areas should be covered and whether the areas are located relatively close to each other or spread far apart. The area will determine the type of camera and number of cameras required.

Fixed or PTZ. (In the following context, fixed cameras refer also to fixed domes and PTZ cameras refer also to PTZ domes.) An area may be covered by several fixed cameras or a few PTZ cameras. Consider that a PTZ camera with high optical zoom capabilities can provide high detail images and survey a large area. However, a PTZ camera may provide a brief view of one part of its area of coverage at a time, while a fixed ip cctv cameras network will be able to provide full coverage of its area all the time. To make full use of the capabilities of a PTZ camera, an operator is required or an automatic tour needs to be set up.
HDTV, megapixel or standard resolution cameras. One of the unique benefits that network video brings to the video surveillance market is the ability to move beyond the traditional PAL/NTSC resolution and frame rate limitations and experience high-resolution video with extreme image detail. HDTV, megapixel and standard resolution cameras have different application areas and benefits. For instance, if there are two, relatively small areas of interest that are close to each other, a megapixel or HDTV camera with a wide-angle lens can be used instead of two non-megapixel cameras.

Day & Night network cameras
All types of network ip cameras—fixed, fixed dome, PTZ, and PTZ dome—can offer day and night functionality. A day and night camera is designed to be used in outdoor installations or in indoor environments with poor lighting.
A day and night, color network camera delivers color images during the day. As light diminishes below a certain level, the camera can automatically switch to night mode to make use of near infrared (IR) light to deliver high-quality, black and white images.
Near-infrared light, which spans from 700 nanometers (nm) up to about 1000 nm, is beyond what the human eye can see, but most camera sensors can detect it and make use of it. During the day, a day and night camera uses an IR-cut filter. IR light is filtered out so that it does not distort the colors of images as the human eye sees them. When the camera is in night (black and white) mode, the IR-cut filter is removed, allowing the camera's light sensitivity to reach down to 0.001 lux or lower.
Day and night cameras are useful in environments that restrict the use of artificial light. They include low-light video surveillance situations, covert surveillance and discreet applications, for example, in a traffic surveillance situation where bright lights would disturb drivers at night.
An IR illuminator that provides near-infrared light can also be used in conjunction with a day and night camera to further enhance the camera's ability to produce high-quality video in lowlight or nighttime conditions.
