Bullet Security Camera
Bullet security cameras and dome cameras have become a staple of home and business security systems. Bullet and dome cameras can be very similar in performance (range, resolution, angle of view). They also cost about the same. The only real difference between dome and bullet cameras is their external housing. The shape and size of the housing limits the kind of lens system that can be used in the camera. This leads to some small differences between the bullet and dome cameras that will dictate whether or not you’d prefer one to the other.
What is a Bullet Security Camera?
A bullet security camera is a cylindrical model that resembles the shape of a bullet. This shape allows space for a zoom lens system (with a longer lens barrel length) to be fitted, which supports long range viewing. Bullet security cameras are designed to support both indoor and outdoor use, such as monitoring the outside of houses or offices. The bullet camera is often favoured when long range viewing is needed, or when you need to focus on a specific area only. Although each bullet camera has a narrow angle of view, you can still observe over a wide angle by installing multiple bullet cameras in a flower-like formation, which is a common sight outside MRT stations in Singapore.
Bullet Cameras or Dome Cameras?
Both bullet and dome camera types offer easy installation, but most of the time, dome cameras are easier to install, as you can just attach it to a ceiling or side wall. For bullet cameras, during installation, you will need to choose the right direction to point the camera, as it may be difficult to adjust it after installation (unless it is a motorised or PTZ camera). However, in some cases, bullet cameras can be easier to install than dome cameras, such as when pole mounting is required.
Both dome and bullet cameras can be equipped with infrared LEDs, ensuring good visibility at night as well as day.
Dome and bullet cameras can be used both indoor and outdoor. Bullet cameras are often weatherproof and tend to have a longer range, which makes them better suited to viewing outdoor areas.
Dome models are often used indoors. The design of dome cameras is often more in keeping with building aesthetics, providing security without reducing appeal.
The range these cameras can cover depends entirely on the models taken into consideration. In general, bullet cameras have more space (barrel length) for lens compared to dome cameras, which makes bullet cameras more suitable for long distance surveillance. A dome camera with equal lens size, however, can match the range of its bullet counterpart.
Dome cameras can have a wide angle of view (over 90 degrees) since their window’s hemispherical shape potentially allows up to 360 degrees of view and it is easy to add on a wide angle lens to increase the angle of view of a dome camera. This allows you to view many directions at the same time with a single camera, if you do not wish to install multiple cameras. Bullet cameras generally do not have wide angles of view.
Overt or Covert
Bullet cameras tend to be more visible due to their protruding shape, and can be larger in size than dome cameras. A large bullet camera at close range pointing towards you can look threatening. This can act as a deterrent, preventing vandalism or crimes. Whereas dome cameras are often harder to spot, and this lends them better to covert surveillance.
Dome cameras are commonly referred to as ‘vandal proof’ and beat bullet cameras when it comes to durability. They are better able to withstand shaking as they are harder to grab, making them ideal if you are unable to place them out of reach. However, bullet cameras can also withstand twisting if they are properly installed.
With sufficient knowledge of your security needs, the above list of factors should help you narrow down the right security camera for you. Dome cameras offer a versatile and durable choice that blends in well with the environment. Bullet cameras provide longer range surveillance and act as a more visible deterrent.
