Verkada Review: How Far Can Dome Cameras See?

When evaluating security camera systems for your business, it’s important to understand the differences between types and models.

For example, you would not want to install a bullet security camera in a 20×20 workspace. Its narrower field of view and long range makes it better equipped for an outdoor environment. And you would not want to install a dome security camera in a parking lot because its wide angle lens will fail at capturing events happening a long distance away.

Not so long ago, the only type of surveillance camera available on the market was a CCTV camera. A CCTV camera is powered by coaxial cables and uses a DVR to record and store data. But the speed of progressive technology has made CCTV surveillance systems almost obsolete. The newest comparison guides found online make no mention of CCTVs at all, instead focusing on wireless versus wire-free IP cameras.

Regardless of wiring though, there is a common question that is being asked among would-be buyers:

“How far can a security camera see?”

Well, it really depends on the type, model, and various influence factors of the camera. In this blog article, I will focus on how far a Verkada dome camera can see.

VERKADA DOME CAMERAS

There are generally three influence factors to take into account when determining the answer to “How far can dome cameras see?”

  • Focal length
  • Camera resolution
  • Placement

FOCAL LENGTH

The focal length of the security camera is another term for the size of the camera lens. Of all the influencing factors, it is the number one factor in determining how far a dome camera can see.

The focal length is measured in mm (millimeters) and can be categorized as “fixed focal length” or “variable focal length.” Fixed focal lenses are commonly used and well suited for standard security surveillance applications. A varifocal lens can be adjusted to capture a wider area or so that it focuses on a smaller area in more detail.

A smaller focal length translates to a wider field of view for the camera. Alternately, a bigger focal length means a narrower field of view for the camera.

Verkada dome cameras come in four different models that vary in distinct ways. Each model has a different lens focal length that meets the needs of different security applications.

CAMERA RESOLUTION

Another influencing factor of how far dome cameras can see is the camera resolution. A high resolution means the details of the imaging can be seen clearer than that of a low resolution camera.

Nowadays, high resolution cameras are becoming much more affordable. 720 pixels used to be the industry standard, but now the lowest resolution that can be found in an IP security camera is generally 1080p. The highest resolution on the market is 4K, which can be known to clearly capture a license plate from more than 100+ feet away.

Verkada dome cameras’ resolutions vary from 1080p to 4K, creating a range of products that fit a variety of different industries and business needs.

PLACEMENT

The last influencing factor of how far a dome camera can see is the physical placement of the camera in the environment being surveilled. Even if your dome camera has incredible range and excellent night vision capabilities, that means nothing if there is an object standing in the way of its field of view.

Verkada dome cameras can be mounted almost anywhere, thanks to various types of mounts available for purchase. Although they are usually found installed on ceilings for a wide field of view, arm mounts, angle mounts, and bracket mounts can all be utilized to install dome cameras on walls, fences, and other stationary objects.

However, it is important to install your dome security camera in a location that is not impeded by trees, open doors, angled walls, and other hindrances. This will allow your security system to function at the most optimal strength.

Now let’s examine the different models of Verkada dome cameras to determine how far each one can see in an average environment.

DOME CAMERA MODELS

CD31 Indoor Dome Camera

  • Lens type: Fixed
  • Focal length: 2.8mm
  • Field of view: 97° Horizontal, 71° Vertical, 128° Diagonal
  • Image sensor: 1/2.8″ Progressive CMOS
  • Resolution: 2MP / 1920 x 1080
  • Range: 15m (50ft)

CD41 Indoor Dome Camera

  • Lens type: Fixed
  • Focal length: 28mm
  • Field of view: 97° Horizontal, 71° Vertical, 128° Diagonal
  • Image sensor: 1/2.8″ Progressive CMOS
  • Resolution: 5MP / 2688 x 1944
  • Range: 15m (50ft)

At first glance these two models do not look very different. They have the same range of 15m with an identical focal length of 2.8mm. However, the CD41 has a higher image resolution. So if you are concerned about the detailing of the area being surveilled, the CD41 might be a better choice for your security needs.

Let’s keep going.

CD51 Indoor Dome Camera

  • Lens type: Varifocal (3x Optical Zoom)
  • Focal length: 2.8-8mm
  • Field of view: 38° to 105° Horizontal, 29° to 77° Vertical, 48° to 126° Diagonal
  • Image sensor: 1/2.8″ Progressive CMOS
  • Resolution: 5MP / 2688 x 1944
  • Range: 30m / 98ft

CD61 Indoor Dome Camera

  • Lens type: Varifocal (3x Optical Zoom)
  • Focal length: 2.8-8mm
  • Field of view: 41° to 116° Horizontal, 23° to 62° Vertical, 47° to 136° Diagonal
  • Image sensor: 1/2.8″ Progressive CMOS
  • Resolution: 4K / 3840 x 2160
  • Range: 30m / 98ft

Like the CD31 and CD41, the CD51 and CD61 are very similar in their form factors. But the CD61 has a higher image resolution and slightly larger field of view range, making this model better suited for a massive warehouse environment that requires very detailed surveilling.

The Verkada dome series does not stop there. Now let’s take a look at the outdoor models and the very popular Fisheye camera.

  • Image sensor: 1/2.8″ Progressive CMOS
  • Resolution: 4K / 3840 x 2160
  • Range: 30m / 98ft

At first glance, the outdoor dome series looks identical to their indoor counterparts. But the outdoor models are slightly bigger in size and include another PoE input that covers an extended temperature range for outdoor environments.

All Verkada dome cameras are durable, versatile, and built to withstand high traffic areas.

The last Verkada dome camera I will examine is one of the most popular models on the market: the Fisheye camera. Its capabilities include panoramic views for seamless 360° coverage in any environment.

CF81-E Fisheye

  • Lens type: Fixed
  • Focal length: 1.18mm
  • Field of view: 180° Horizontal, 180° Vertical, 180° Diagonal
  • Image sensor: 1/2.3″ Progressive CMOS
  • Resolution: 12 MP (4056×3040)
  • Range: 20m / 65ft

The CF81-E Fisheye is unique, especially in how it can operate in three different viewing modes:

  • 180° Panoramic: A wide-angle view best for an open area or a corridor.
  • Four-way split: Monitor four different fields of view with a single camera.
  • Pan-Tilt-Zoom (ePTZ): An immersive 360º view that captures everything happening within your physical surroundings.

 

 

With the pan tilt zoom function, users can quickly toggle between a 360º fisheye view and a PTZ view where they can use their cursor to freely move the frame vertically and horizontally.

The applications for the CF81-E Fisheye are limitless; this security camera can literally be put in any location that needs 360º coverage, or places like stairwells that require a split in the field of view.

So, how far can a dome camera see? Well, it depends on the three influencing factors of lens focal length, resolution, and placement.

Verkada dome cameras can see in a range of 50-98 feet, presuming that their field of view is not physically impeded by anything.

Keep in mind that this examination of camera range is only the tip of the iceberg when it comes to Verkada camera capabilities. Verkada security cameras are hybrid cloud-based systems that don’t require a DVR, NVR, or server of any kind. Each camera includes unlimited storage on the camera and in the cloud, and requires a simple plug-and-play installation. Verkada cameras are built to scale and include regular automatic software updates.
