Dome Security Camera

Both dome security cameras and bullet cameras have become a staple of home and business security systems. This is because a dome security camera offers users an easy-to-install and completely controllable tool when it comes to managing areas of any size. Both camera types are very similar, and in fact offer similar performance in terms of internal electronics (range, resolution, power consumption). They also cost about the same. But there exist some small differences that will dictate whether or not you’d prefer one to the other. The difference between dome and bullet cameras lies in their external housing, which limits the kind of camera that can be fitted inside it.

What is a Dome Security Camera?

A self-explanatory question perhaps. Dome security cameras are small, dome-shaped cameras that are commonly seen hanging from ceilings in the vast majority of retail buildings and banks. The dome casing is typically tinted with a dark color and this means those in its presence will never know the direction the camera is facing. Dome cameras provide 360-degree surveillance, making them ideal for locations inside buildings.

Dome Cameras or Bullet Cameras?


Dome cameras are usually easier to install, most often simply attached to the ceiling or wall directly. The advantage of a dome camera is that even after installing it, you may rotate the camera internally in the dome housing to any direction. But bullet cameras need to be mounted on a pole and pointed in the right direction during installation (as it may be troublesome to rotate it after installation). Dome cameras can be pole mounted too, but this requires more setup.


Both dome and bullet cameras can be equipped with infrared LEDs, ensuring good visibility at night as well as day.


Dome cameras are ideal for indoor purposes. The design of dome cameras is often more in keeping with building aesthetics, providing security without looking obtrusive. For HDB owners, using dome cameras at your home entrance is also less likely to alarm your neighbours. As dome cameras are common in HDBs, dome cameras tend to be a bit cheaper, due to economies of scale.

Bullet cameras, on the other hand, are often weatherproof and tend to have a longer range, which would make them better suited to viewing large outdoor areas.


The range these cameras can cover depends entirely on the models taken into consideration. But in general, dome cameras do not have as much space (barrel length) for lens compared to bullet cameras, which makes them less suitable for long distance surveillance. Of course a dome camera with equal lens size would match that of its bullet counterpart.

Viewing Angle

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

The shape of a dome camera blends into its environment, and it is difficult to spot the location of its lens to see where exactly the camera is pointing at, so this lends them better to covert surveillance. In contrast, bullet cameras tend to be more visible due to their protruding shape. This can act as a deterrent, preventing vandalism or crimes.


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.

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.
