Security Camera Systems – Multisensor and Fisheye Panoramic Cameras

Security camera systems are becoming more commonplace in schools and campuses across America. They are a practical and affordable way to improve security conditions. In fact, statistics show that, by 2023, the global video surveillance market could reach 62.62 billion U.S. dollars in revenue. 

However, you can also use these security camera systems for non-security purposes and can help end-users with their business intelligence. Beyond the security aspect, surveillance cameras can decrease shrinkage, resolve staff and customer disputes, and even prevent fraudulent claims. In a work environment for example, where there are incidents of conduct that violate the workplace code (theft, tardiness, abuse of office resources) having surveillance footage to clear up what did or did not happen is incredibly beneficial and can prevent costly legal disputes. 

Business Security Systems

In the retail environment, stats say that there could be as many as 275 million incidents of retail theft globally. This figure is alarming, so boosting your security through better surveillance is a no-brainer. 

If you are considering installing security camera systems, one of your key decisions is whether to go with multisensor or fisheye panoramic cameras. Each system functions in a specific environmental setting. To help you make the right decision, here are some of the key pros and cons of each. 

Fisheye Panoramic Cameras

A fisheye panoramic camera uses a panomorphic lens to capture a 360° view of the surroundings. They produce a circular image of a scene, which will initially appear warped as a result of the fisheye lens. 

By using a fisheye camera, you will be able to see areas from below the camera, to above the horizon of their mounting point. For detailed campus security systems, fisheye cameras require de-warping software. This corrects the lens image distortion in the video stream to produce usable surveillance images.

We recommend the fisheye security camera system for smaller spaces, specifically in retail and interior office space settings. 

Fisheye cameras prefer these environments due to the fact that they are quite compact and unobtrusive, all while offering wide area coverage. Other advantages include that they are more cost-efficient than the multisensor option. Installation is also simple, and they have virtually no blind spots.   

Don’t place fisheye cameras near ceiling lamps. These will interfere with the image signal and also affect the quality of the image. 

On the downside, these cameras have an average score in low light conditions. And, they also require the installation of de-warping software. This software needs to be compatible with the video management system (VMS) to produce better images. 

Multisensor Cameras

The multisensor security offering ensures 180°, 270°, and 360° fields of view using multiple sensors in a single camera housing. Individual snippets of imagery from each sensor combine and ‘stitch’ together, creating a single video stream image.

Because of the extensive range the camera has, each individual sensor can be electronically zoomed in on. This flexibility allows a single multisensor camera to provide the same detailed coverage as multiple conventional fixed cameras at a fraction of the cost. 

Multisensor cameras configure in three ways:

  • 180° viewing to provide surveillance along an expansive horizontal viewing field, such as a street, runway, or a parking lot. 
  • 270° viewing is ideal for situations where it is necessary to see out across the horizon and also below the camera. So, they are well suited to being placed at the corner of a building. 
  • Finally, by configuring the camera for 360° views, you will have a comprehensive panoramic view of your full surroundings. This specific setting is ideal for parking lots, airports, railway yards, street intersections, or anywhere where there are wide open spaces that demand high-quality surveillance.

Multisensor cameras also offer advanced electronic pan, tilt, and zoom functionalities. These allow operators to view specific areas of interest in much more detail than the fisheye lens. All while still viewing and recording the complete panoramic scene.

Multisensor cameras have no real cons. Even though they are more expensive than fisheye, they are good value for money. You will require far fewer cameras per site. In addition, the multisensor versions are usually designed with an extensive range of feature-rich analytics and alerts. This includes adaptive motion detection, loitering detection, and stopped vehicle detection. These not only provide you with peace of mind but can also improve productivity as you can spend less time on 24-hour monitoring. 

It is important to remember that there’s typically a big resolution boost with a multisensor camera and you don’t need to deal with de-warping. 

What Security Camera System is Right for You?

Knowing and understanding how business security systems and their cameras contribute to overall surveillance system operations can create higher levels of situational awareness and ultimately a safer and more secure environment. 

While it may seem that multi-sensor cameras would be ideal for any type of installation, they might not be right for you, especially if you’re considering surveillance for a small store or office. 

The multisensor surveillance cameras, on the other hand, would be better suited to bigger installations in large retail settings, universities and schools, stadiums, and for areas that are more at risk for terrorist attacks, such as airports.
