Basic Security Camera Terms Defined
In this section of the ultimate guide to security camera terminology, we’ll break down simple but essential terms to help you better understand how security systems work. Whether you’re shopping for a new setup or upgrading, knowing the basics helps you choose smarter.
At Cam Security Surveillance, we believe clear knowledge leads to better security choices. Here are the core terms you need to know.
Camera vs Surveillance System
A camera is just one device used for recording video; however, a surveillance system consists of multiple cameras connected with each other, along with storage such as DVR or NVR storage units, monitors, and apps; it provides comprehensive protection of your property.
DVR and NVR
DVR stands for Digital Video Recorder and works with analog cameras. It records lower-resolution video and uses coaxial cables.
NVR stands for Network Video Recorder and is used with digital IP cameras. It records in higher quality, supports features like remote viewing, and works well with 4K security camera systems.
When comparing NVR vs DVR, NVR is the more modern and flexible option.
Resolution
Resolution means how clear the video is.
- 720p is entry-level
- 1080p is standard
- 4K security camera systems offer the sharpest image, great for large spaces or license plate capture
Frame Rate
Frame rate or FPS means how smooth the video looks.
- 15 FPS is basic
- 30 FPS is standard
- Higher FPS gives clearer video for fast movement
Field of View
This shows how wide a camera can see. Wide-angle cameras cover more area, while narrow views focus on smaller spots like doors or hallways.
Types of Security Cameras Explained
In this section of the ultimate guide to security camera terminology, we’ll explore the most common types of cameras used in homes and businesses. Understanding these options helps you make smarter decisions when installing a security camera system that fits your needs.
- Dome Cameras – Ideal for indoor use and offer a discreet appearance
- Bullet Cameras – Best for outdoor surveillance with visible deterrent effect
- PTZ Cameras – Allow pan, tilt, and zoom control for large area coverage
- Turret Cameras – Versatile and easy to install with excellent image clarity
- Hidden Cameras – Small and discreet, perfect for covert monitoring
- IP Cameras – High-resolution digital cameras that use network connections
- Analog Cameras – Traditional cameras using coaxial cables and DVRs
Choosing the Right Camera for Your Space
Selecting the right camera style depends on your environment, coverage needs, and how visible you want the device to be. To deter crime when it’s become common in many areas, having the right mix of visible and discreet surveillance can offer both prevention and peace of mind. With this foundation in security camera terminology, you can better understand system features and functionality before making a decision. Trust Cam Security Surveillance to help guide you through the process and ensure a setup that truly protects.
Image & Video Quality Terminology
As we move through this comprehensive guide to security camera terminology, it’s vital to understand how video quality affects performance. From observing dim alleyways to photographing faraway faces, understanding key terms helps determine what your camera can actually deliver.
- Lux Rating – Measures how well a camera performs in low-light; the lower the lux, the better the night visibility
- WDR (Wide Dynamic Range) – Balances lighting in scenes with both dark and bright areas, like windows or outdoor entryways
- Color Night Vision – Lets your camera capture full-color video even in darkness, enhancing detail
- IR LEDs and Infrared Range – Enables black-and-white night vision and determines how far a camera can see in the dark
- Megapixels vs Resolution – Megapixels refer to the image size; resolution (like 1080p or 4K) defines clarity during live view or playback
Why Video Quality Terms Matter
Many homeowners and business owners ask not just how cameras work, but how far they can see, how clearly, and under what lighting. These camera terminology terms are key to understanding that. For instance, a 4MP camera with poor WDR may struggle more than a 2MP with excellent WDR in changing light. And if you’re using a POE system, higher resolution means you’ll need stronger network bandwidth. At Cam Security Surveillance, we factor in all of these elements with every security camera installation Indianapolis clients trust us with because getting it right means seeing the details that matter most.
Power and Connectivity Terms
Understanding how your camera connects and operates is as essential to its image quality as understanding how the image itself was captured. Your perfect setup depends on factors like budget and flexibility requirements.
- Wi-Fi Cameras – Easy to install and connect wirelessly, but depend on a strong internet signal
- Hardwired vs. Wireless – Wired cameras offer steady power and connection, while wireless cameras are easier to place but rely on batteries or Wi-Fi
- Battery-Powered Cameras – Great for temporary setups or hard-to-wire areas, but require regular charging or replacement
- Cloud-Based vs. Local Storage – Some systems offer free cloud storage, while others store footage on-site using SD cards or recorders
Making the Right Connection
What your security cameras need comes down to where they’re placed and how reliable you want the system to be. If you’re working without WiFi, wired cameras or models with local storage are more dependable. If mobility or ease of use is a priority, wireless or battery-powered options are a better fit. Either way, understanding these power and connectivity terms helps you choose smarter. As always, Cam Security Surveillance is here to guide you with expert recommendations tailored to your space and needs.
