Safety is a big concern for many people. That’s the reason why most of the people are more and more willing to invest in a surveillance camera. However, there are different types of security cameras. Besides, we can count several. Each camera has a diverse technical aspect. Thus, a PTZ camera will not be used in the same way or for the same purpose compared to a dome camera.

You can install various high-quality security cameras at your home or business in a specific location. Here are some types of surveillance cameras that exist in the market. These are the top-rated cameras that you can install yourself.

PTZ/Speed Dome camera

The PTZ camera is one of the ultimate security cameras. This type of camera allows access to several surveillance locations. In fact, PTZ cameras have a motorized lens. This is because these types of cameras can move their lens left or right (pan) and up and down.  Even it can zoom from the lens.

Moreover, some of these cameras, the zoom is not optical but digital. Optical zoom is much better than digital zoom. Indeed, the quality of the zoomed image completely surpasses a digitally zoomed image.

PTZ cameras are preferable in areas where a single camera is required. This helps to prevent lousy light conditions such as sun exposure, the presence of a street lamp, etc. These PTZ cameras can be easily installed on any given point around the area to cover. Because they can always zoom in and move in any direction.

Advantages of PTZ cameras

  • Cover a wide area
  • Ability to rotate, tilt and zoom

Disadvantages of PTZ cameras

  • Likely to be affected by low light
  • PoE can only power not all cameras. Some of them may have an Ethernet cable but must have a power supply to function properly.

Indoor and outdoor PTZ camera

You can use PTZ cameras indoors or outdoors. However, the size of the camera will not be the same. Indeed, the PTZ cameras installed outdoors and are big enough to take a little space, compared to internal PTZ cameras.

The outdoor PTZ cameras are, therefore, quite large. Their size can vary from the size of an ostrich egg to a small rugby ball. So yes, nothing to do with another surveillance camera! Besides, outdoor PTZ cameras are generally connected with two cables: an electric one, and a network cable. This is due to the fact that enough energy is obligatory to power the small internal motor of the camera. However, a PoE power alone would not be enough.

Indoor PTZ cameras have the same functionality and features as outdoor PTZ cameras. The only difference is that an indoor PTZ camera is not weather resistant.

IP surveillance cameras

Surveillance technologies have evolved continuously since the introduction of the very first analog cameras and video recorders. Today we are in the era of high-performance IP surveillance cameras. It provides us with better accessibility and even more easy surveillance system control.

The main advantages of IP surveillance cameras are:

  • Easy installation, wireless, accessible to all.
  • Embedded digital processing is allowing storage on a server or memory card.
  • Improved digital zoom.

They are called IP cameras because IP refers to the Internet Protocol. That is the method used by these cameras to transmit video. This technology, therefore, allows these cameras to send the information, which they record to a central DVR point without using a wired connection.

The number of pixels that an IP camera can process range from 720p and 1080p to more than 5 megapixels for high-end models. The more pixels the IP camera has, the more comprehensive the image.

Hidden surveillance cameras

When a person knows that they are constantly under observation, they are more likely to behave as expected. It is the magic of deterrence offered by surveillance cameras.

But if you really want to find out what’s going on behind the scenes, then use hidden cameras. A strategically placed hidden camera will give you full access to the behavior of the people you want to watch.

These invisible cameras allow you to monitor the behavior of your employees, your babysitter, etc. The choice of the type of camera you need depends on the level of discretion you want. Further, it also depends on the equipment present in your facility.


It is quite simply a camera disguised as an object having an integrated digital recorder. (Therefore autonomous) It is easy to install. The device will offer you a discreet recording.

In this camera, information is usually stored via an SD card and to save memory. The majority of these devices use motion detection technology to notify the recorder when to start and stop recording.


If you want to pair your hidden camera with a surveillance camera system, then a pinhole camera is a great choice. They are physically much smaller, the size of a postage stamp. But produce a crisp, clear image. You can hide Pinhole cameras in almost any object.

Bullet camera

Another type of security camera is the bullet (or “bullet”) type camera. This kind of camera is mainly suitable for indoor uses because you can install them easily on a ceiling or a wall. Nevertheless, this kind of bullet camera may also well suited for outdoors as long as the camera is certified for outdoors, no worries.

HD-SDI cameras

 HD-SDI (High-Definition Serial Digital Interface) cameras are the ones that give you the best picture quality possible. They are the most efficient but also the most expensive.

They transmit 1080p video sequences, which are then compressed in H.264 format for storage and playback at a later time. The image quality is at the same level as the Blu-Ray movie or an HD TV. The resolution can be up to 6 times higher than that of standard security cameras.

Whether you choose a pinhole or standalone hidden camera, keep in mind that the majority of these cameras have a wide-angle fixed focal lens. This means that the camera will capture the most extensive field of view. Therefore it is vital to place the camera at the right distance during mounting.

Dome cameras

The dome cameras are the best-known surveillance cameras. These are high-quality cameras. Generally suitable for places welcoming the public, such as shops where the camera must be discreet, but visible. The camera is preserved in a housing dome, hence their name. The housings in which they generally intended to ensure that the camera will not (or hardly) deteriorated in case of (attempted) vandalism.

Turret cameras

A turret camera is a type of camera with a rotating lens. This kind of camera is like a sphere that can be easily rotated around its “socket” once the base has been secure. Turret type security cameras are also known as a mini-dome or eyeball security cameras. Generally, turret security cameras have excellent night vision quality.

Conclusion on the different types of security cameras

So there are different types of surveillance cameras on the market. But all are not equal, and not all are for the same purpose. Before engaging in the purchase of a security camera, it is necessary to reflect and anticipate the location of these cameras.
