Frequently Asked Questions
What is an NVR and how does it work?
NVR stands for Làm phim 2d inforgraphic
. An NVR recorder is responsible for receiving, displaying, & storing surveillance video from IP cameras in a modern security camera system, & serves as a central hub for remote monitoring via điện thoại thông minh apps or PC. Despite the name, network video recorders bởi not require mạng internet access & can be used as part of a standalone closed circuit surveillance system .
Power nguồn kết thúc Ethernet ( PoE ) công nghệ is used by NVR security recorders phệ send power & receive dữ liệu from PoE cameras. PoE is extremely convenient because it does not require the use of an external power supply or difficult & expensive coaxial cabling. To kết nối béo cameras, network cabling can be run up phệ 300 ft away from a PoE NVR. External extenders & PoE switches are available for cameras installed farther than 300 ft away. There are also NVR systems with a built-in wireless network for WiFi security cameras, which we discuss in greater detail below .
Is there a Universal NVR? Can I use any security cameras with any NVR recorder?
The short answer is no ; there is no Universal NVR that works with any security camera on the market. The reason for this is that each manufacturer has their own proprietary software & video transfer protocols. Even minor differences in firmware within the same brand or manufacturer can cause compatibility problems .
The long answer is that some NVRs provide enhanced compatibility via a loose industry standard known as ONVIF. ONVIF is a protocol that provides a video stream between a camera & an NVR but does not guarantee audio, motion detection, PTZ control, và other features that would otherwise work with truly compatible equipment. More information about the protocol can be found in our Understanding ONVIF và its Limitations article .

Do you want advanced features like AI Smart Motion Detection, fisheye lens dewarping, people counting, etc?
While many of our network camera models include basic Smart Detection features such as digital tripwire & intrusion detection, not all of them tư vấn the advanced features offered by some of our better cameras. The NVR must also tư vấn the advanced features in order béo configure & record the cameras that have smart detection .
Fisheye lens dewarping for 180 và 360 degree cameras, people counting, abandoned & missing object detection, face detection, & AI Smart Motion Detection are just a few of the features available on our high-end IP cameras. Thes e features are available on a limited number of cameras & are only supported by our top-tier NVRs .
What does the encoding rate or mbps mean?
The Total Encoding Rate, also identified as ” Mbps Encoding Bitrate ” or ” Total Mbps Encoding, ” refers phệ the recorder’s ability Khủng process video dữ liệu from cameras. When selecting a NVR recorder, make sure it has sufficient encoding power phệ handle the number of cameras you intend bự kết nối bự it .
The Mbps used by a camera is determined by the codec ( H. 264 or H. 265 ), resolution, framerate, và bitrate. 1080P cameras, for example, typically use 2M bps bự 4M bps. 2K cameras consume between bốn & 6M bps. 8MP ( 4K ) cameras can use up Khủng 12M bps but typically use 8M bps .
You can calculate the total encoding bitrate your cameras will use by adding their individual bitrates. Pick an NVR that supports the total encoding rate needed. Encoding limitations are generally not an issue unless you kế hoạch on purchasing 4K cameras for each channel. For easier calculations, we suggest using our NVR DVR storage calculator .
Which hard drive should you purchase? How many days of video storage are you looking for?
The amount of phút giây a security camera recorder can record và store surveillance footage before it is overwritten is determined by three factors : the cameras, the hard drives inside the recorder, & the recording strategy. Depending on these factors, systems can record for a few days, a couple weeks, or months .
Cameras with high resolution cameras such as 4K consume more storage space than cameras with lower resolution. The same can be said for higher vs. lower framerates .
The hard drives you buy will eventually determine how much video the system can store. A larger capacity drive can store more footage. Buying multiple large capacity drives will give you plenty of space for video. To kế hoạch for your storage requirements, feel không tính tiền bự use our Security NVR và DVR Hard Drive Calculator. Please tương tác us if you need assistance determining how much storage lớn purchase .
Setting up a recording strategy will significantly increase the amount of thời gian you can record. Creating a strategy involves carefully planning when your system will record continuously, on video-based motion, or when Smart Detection features are used. Only record continuously during the day when there is a lot of activity in và around your business or home page, và only record based on motion detection at night. A more advanced và powerful recording strategy involves continuously recording the lower resolution substream while only recording the đầy đủ resolution mainstream when motion is detected or a detection rule is triggered .
