IP Camera form factors: The ultimate guide to selecting the right camera for your installation

IP cameras have revolutionised the surveillance industry, offering unparalleled flexibility, scalability, and remote accessibility. One key factor to consider when selecting an IP camera is its form factor. Different types of cameras cater to specific needs and environments, ensuring optimal performance and functionality. In the previous article, we compared analogue and IP surveillance. This time, we’ll dive into different types of IP cameras and explore their ideal applications.

Bullet Network Cameras

Bullet cameras are characterised by their elongated, cylindrical shape.  They are typically equipped with a fixed lens and are designed for outdoor or high-security applications. Bullet cameras are ideal for monitoring areas with limited space, such as corridors, hallways, or parking logs. Their robust construction and weather-resistant capabilities make them suitable for harsh outdoor environments. 

Dome Network Cameras 

Dome cameras feature a hemispherical or spherical dome-shaped enclosure. They are available with fixed and varifocal lenses, offering flexibility in field of view adjustment. Dome cameras are commonly used in indoor environments, such as retail stores, offices, and public spaces. Their discreet design and wide-angle coverage make them suitable for unobtrusive surveillance.

Fisheye Network Cameras 

Fisheye cameras boast a unit 180-degree or 360-degree field of view, providing a panoramic perspective of the surrounding area. They are often used in applications where a wide-area view is required, such as large warehouses, parking garages, or public squares. 

PTZ Network Cameras

PTZ (Pan-Tilt-Zoom) cameras offer the flexibility to remotely control the camera’s direction and zoom level. They are equipped with motorized pan and tilt mechanisms, allowing users to focus on specific areas of interest. PTZ cameras are commonly used in applications where precise monitoring and tracking are required, such as airports, stadiums, and critical infrastructure. 

What are the differences between a Fixed and a varifocal lens?

Fixed Lens Camera

A fixed lens camera has a set focal length, which determines the field of view and magnification. This means that the camera cannot zoom in or out. Fixed lens cameras are often used in applications where a specific field of view is required and there is no need for adjustable magnification. Some common use cases for fixed lens cameras include:

  • Corridors and hallways: fixed lens cameras can provide a wide-angle view of these areas, allowing for easy monitoring of activity 
  • Parking lots: fixed lens cameras can be used to monitor vehicles entering and exiting a parking lot, as well as to identify suspicious activity. 
  • Retail stores: fixed lens cameras can be used to monitor customers and employees, as well as to deter theft. 

Varifocal lens cameras 

A varifocal lens camera has a variable focal length, allowing it to zoom in and out. This provides flexibility in adjusting the field of view to focus on specific areas of interest. Varifocal lens cameras are often used in applications where there is a need to monitor a large area or to zoom in on specific details, some common use cases for varifocal lens cameras include:

  • Outdoor perimeters: varifocal lens cameras can be used to monitor large areas, such as parking lots or industrial complexes. 
  • Crucial infrastructure: varifocal lens cameras can be used to monitor sensitive areas, such as power plants or high sites. 
  • Sports stadiums: varifocal lens cameras can be used to capture close-up shots of athletes and or the crowd. 

Here are some key differences between fixed and varifocal lenses 

Choosing the right camera for your surveillance requirement 

When selecting an IP camera, consider the following factors:

  1. Environment: Will the camera be used indoors or outdoors? What are the environmental conditions, for example, temperature, humidity, lighting, etc? 
  2. Field of view: What is the desired area of coverage? Do you need a wide-angle view or a narrow field of view?
  3. Level of Detail: how much detail do you need to capture? Will the camera be used for facial recognition or license plate recognition?
  4. Budget: What is your budget for the installation of the IP camera?
  5. Low light performance: If the camera will be used in low-light conditions, it is important to choose a model with functions such as Starlight from UNV, high 2/3DNR (Digital Noise Reduction), or even a model with built-in LED lights. 
  6. Network Bandwidth – take careful consideration of the MP (mega-pixel) of a network camera, some cameras can go up as much as 8MP – but this single 8MP camera will take much more bandwidth when compared to a 2MP camera.

By carefully evaluating these factors, you can choose the most appropriate IP camera to meet your surveillance requirements.
