Frequently Asked Questions

NVR stands for Network Video Recorder. An NVR recorder is responsible for receiving, displaying, and storing surveillance video from IP cameras in modern security camera systems. It serves as a central hub for remote monitoring via smartphone apps or PCs. Despite its name, network video recorders do not necessitate internet access and can operate as part of standalone closed circuit surveillance setups. NVR security recorders employ Power over Ethernet (PoE) technology, delivering power and receiving data from PoE cameras. PoE is highly convenient, eliminating the need for external power supplies or complex, costly coaxial cabling. With PoE NVRs, network cabling can be extended up to 300ft away from cameras. For installations exceeding this distance, external extenders and PoE switches are available. Some NVR systems even feature built-in wireless networks for WiFi security cameras, which we elaborate on below.

In short, there is no Universal NVR compatible with all security cameras on the market. This is due to varying manufacturers' proprietary software and video transfer protocols. Even minor firmware distinctions within the same brand can lead to compatibility issues.

While some NVRs offer improved compatibility via the ONVIF protocol, it only facilitates video streaming between a camera and NVR and does not guarantee audio, motion detection, PTZ control, and other functions that truly compatible equipment would offer. For more details on the protocol, refer to our Understanding ONVIF and its Limitations article.

If you're considering new equipment alongside existing cameras or an NVR, please reach out to our support department or give us a call for expert compatibility guidance.

Craving the epitome of excellence? Our 5 and 6 series NVRs support even higher 4K video resolutions at 12MP, delivering unprecedented image clarity at 4000x3000 pixels along with impeccable digital zoom capabilities.

While several of our network camera models encompass basic Smart Detection functionalities like digital tripwire and intrusion detection, not all support the advanced features present in certain top-tier cameras. Moreover, the NVR must also align with these advanced features to configure and record cameras equipped with smart detection capabilities.

From fisheye lens dewarping for 180 and 360-degree cameras to people counting, abandoned and missing object detection, face recognition, and AI Smart Motion Detection, our premium IP cameras offer an array of advanced capabilities. These functionalities are accessible on a select range of cameras and are exclusively supported by our highest-tier NVRs.

The Total Encoding Rate, also referred to as "Mbps Encoding Bitrate" or "Total Mbps Encoding," pertains to the recorder's capacity to process video data from cameras. When choosing an NVR recorder, it's imperative that it possesses ample encoding power to accommodate the number of connected cameras. The Mbps consumed by a camera depends on factors like codec (H.264 or H.265), resolution, framerate, and bitrate. For instance, 1080P cameras generally utilize 2Mbps to 4Mbps, while 2K cameras require 4 to 6Mbps. 8MP (4K) cameras may use up to 12Mbps but typically operate at 8Mbps.

Calculate the cumulative encoding bitrate by adding individual camera bitrates, then select an NVR supporting the required total encoding rate. Encoding limitations are usually inconsequential unless you plan to employ 4K cameras for every channel. For simplified calculations, our NVR DVR storage calculator is recommended.

The duration a security camera recorder can store surveillance footage before overwriting is determined by camera specifications, internal recorder hard drives, and the recording strategy. Based on these factors, systems can retain data for a few days, weeks, or months.

Cameras with higher resolutions like 4K consume more storage than lower-resolution counterparts. The same principle applies to higher versus lower framerates.

The selected hard drives ultimately determine storage capacity. Larger capacity drives provide increased storage. Employing multiple large capacity drives ensures ample space for video content. For precise storage planning, make use of our Security NVR and DVR Hard Drive Calculator. Feel free to reach out if assistance is required in gauging storage needs.

Employing a well-thought-out recording strategy significantly extends recording duration. Crafting a strategy involves defining periods for continuous recording, video-based motion triggers, or utilization of Smart Detection features. Continuous recording during active daytime periods while reserving motion-based recording for night hours is one approach. An advanced strategy involves continuous recording of lower-resolution substreams, activating full-resolution recording solely upon motion detection or rule triggers.
