Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| DVR and NVR are the same thing. | DVR (Digital Video Recorder) and NVR (Network Video Recorder) are two different types of video recording devices with distinct features and functionalities. While both record video footage, they differ in terms of how they process and store data. |
| DVRs can only be used for analog cameras while NVRs can only be used for IP cameras. | This is not entirely true as some modern DVRs support IP camera inputs, while some NVRs have hybrid capabilities that allow them to work with both analog and IP cameras. However, it’s important to note that each device has its own limitations when it comes to compatibility with different camera types. |
| The quality of recorded footage depends solely on the type of recorder used (DVR or NVR). | While the type of recorder plays a role in determining the quality of recorded footage, other factors such as camera resolution, lens quality, lighting conditions, compression algorithms used also affect the overall image quality captured by a surveillance system. |
| All DVR/NVR systems come with built-in storage capacity. | Some entry-level models may require external hard drives or memory cards for storage expansion while high-end models may offer multiple options including cloud-based storage solutions in addition to internal storage capacity. |
| Upgrading from a DVR system to an NVR system requires replacing all existing equipment. | It’s possible to upgrade from a traditional CCTV setup using coaxial cables connected directly into your old analogue VCR/DVD player/monitor combo without having to replace everything at once by adding an encoder which will convert your analogue signal into digital format so you can use it over Ethernet networks like those found on most modern-day computers or routers today! |
