Understanding Key Construction Camera Specifications
With all of the uncontrollable factors that can impact construction projects, remote monitoring is an increasingly effective solution for builders and project managers. But with so many technical terms and specifications, it’s easy to feel overwhelmed when looking for the right camera for your project.
As you take the next step in ensuring safety, productivity, and security, here are the essential specs to know about when choosing the best construction camera for your goals and needs:
Still Image Resolution
One of the most commonly discussed specifications is the megapixel (MP) count. But what exactly does it mean? A megapixel refers to the number of pixels (tiny dots of color) in an image. For example, a 5MP camera captures images with a resolution of 2592 x 1944 pixels. To put it into perspective, think of the dimensions as the size and scale of the image.
Fixed camera resolutions can range anywhere from 2 to 20 MP. While a lower MP camera can provide a decent level of detail for basic monitoring needs, higher resolution cameras like a 12MP or 20MP are excellent for capturing high-detail images.
Video Quality
When it comes to video quality, two common terms you’ll encounter are 1080p and 4K. 1080p refers to a resolution of 1920 x 1080 pixels, and 4K offers a higher resolution of 3840 x 2160 pixels. More pixels equal sharper image quality, which is crucial to capturing important details on your jobsite.
Clear video enables project managers and stakeholders to closely monitor progress, identify any issues, and ensure quality control. Moreover, it helps with the detection of safety violations, promoting a safer work environment and facilitating prompt corrective actions when necessary.
Frames per Second
Frames per Second (FPS) refers to the number of frames (individual images) captured by the camera per second in a video. The industry standard is typically around 24-30 fps. For a jobsite camera, this range is sufficient. You may see some cameras that boast a higher fps, but it’s important to know that to the naked eye, you won’t be able to tell a difference in video quality.
Focal Length
Focal length determines the magnification and angle of view provided by a camera lens. For example, imagine you’re standing at a fence and looking at a sprawling farm field with a small red barn in the distance. At 20mm focal length, the barn appears as a tiny red dot on the horizon. But at 120mm focal length, you can now see the barn, its roof, and the trees around it fairly clearly. You can even spot the second, smaller barn nearby that you couldn’t see before!
A good fixed jobsite camera usually has a focal length ranging from 4–20mm. This range allows you to capture a broad view of your jobsite. For a PTZ, you can expect to see much higher focal lengths, with a good PTZ having a focal length of 4–100+mm to allow clear viewing of objects far away.
Field of View
Field of View (FOV) refers to the area visible through the camera lens. A wider field of view provides you with a vast amount of data and information by allowing you to see more at once. With a camera that offers wide-angle coverage, you may not need multiple cameras to monitor your entire jobsite effectively.
Infrared
Infrared (IR) sensors are devices that detect infrared radiation, which is invisible to the human eye. These sensors detect the heat emitted by objects and convert it into a visible image, allowing cameras to capture clear footage in low-light conditions. Cameras with built-in IR are particularly useful for projects that operate around the clock or require continuous monitoring overnight.
IR range in construction cameras refers to the maximum distance at which the camera’s infrared sensors can capture clear images in low light conditions. This range can vary between different camera models and should be considered when selecting a camera suitable for the size and requirements of the construction site.
Hardware Rating Systems
There are three common rating systems for the durability of cameras, accessories, and enclosures:
- Ingress Protection (IP) ratings tell you how protected your equipment will be against dust and liquids.
- NEMA ratings provide information on an electrical enclosures’ ability to withstand water, corrosion, and other hazards.
- IK ratings tell you a component’s level of protection against impact and vandalism.
By understanding and considering these ratings, project managers and builders can select cameras and equipment that are best suited to the specific conditions of their construction sites.
Other Important Considerations for Construction Site Cameras
In addition to the specifications mentioned above, there are a few more factors to consider when selecting a construction site camera:
- Adequate storage space: Make sure the camera includes enough data for your project requirements. Running out of storage or incurring additional charges for exceeding limits can be frustrating and expensive.
- Connectivity options: Look for a camera with built-in 4G LTE or the ability to connect to onsite Wi-Fi. This ensures you can access the camera remotely without driving up your data costs.
- Ease of use: Installation and operation should be straightforward. Choose a camera that doesn’t require excessive technical expertise to set up and operate effectively.
- Responsive support: No system is perfect, so reliable and responsive customer support is crucial. Ensure the camera provider offers prompt assistance when you need it.
