Like cars, surveillance cameras also come in different shapes, sizes, and models. While one size cannot fit all due to habits and needs, it is vital to arm with some background knowledge of what is available out there in the surveillance market, so that we will not side way too much from we ideal.
The dome shaped camera is probably one of the most commonly seen surveillance cameras on the streets. Even though they are round on the outlooks, their lenses are able to be adjusted manually to a specific and desired direction. Coming with day and night features and also an in-system infrared which enables continuous capturing of footages regardless of light situations, these dome cameras usually embed with P-iris lens for a wider view of front, back, and surround. The outdoor model not only able to withstand weather but is also waterproof, it can be submerged to two meters in water.
The bullet shape camera is also prominently seen in many parts of a city, especially within buildings. Similarly, the bullet shape cameras are also adjustable, with their lenses focusing on a particular direction. However, the distinct different between dome and bullet cameras are the better range and zooming abilities of the latter.
Nevertheless, the bullet shape camera also has its own unique down side, which is to be identified as surveillance almost immediately. If a person pointed to you that there is a surveillance camera around, highly likely that they are looking at a bullet shape camera. As a result, it is important for users to know if they will like the cameras to be in disguise. Moreover, even though bullet shape camera is extremely waterproof and more frequently used in the outdoor setting, the designs of these cameras are actually rather vulnerable to man-made damages and tampering because there is no additional protection.
If users are not keen on elaborate installation, a box camera will perhaps fall within their expectation because of its size. A box camera is minute yet still able to have a close up to the targeted surveillance area; it is also able to zoom in close to a fixated direction. While box camera only allows a single direction capture, on the other extreme, there is the Point-Tilt-Zoom (PTZ) camera, which allows users to remotely control what they will like to see.
