These NVRs are video recorders for Onvif IP cameras. They are used to manage and record cameras in an IP video surveillance system. With these NVRs you can control all our IP cameras and also those of other manufacturers, using the ONVIF universal protocol , which is today a widespread international standard.
These NVRs are part of our RK range which also includes DVRs with BNC inputs and IP cameras . This range is designed for the residential and commercial market segments. It combines excellent performance with the most convenient functions for the private user, still providing a high quality / price ratio. All cameras and video recorders in this range are suitable for our IoVedo.RK mobile app and share the same P2P cloud server and software tools for computers.
Why do NVRs exist if IP cameras can record on their SD card and can be managed with a computer? NVRs exist because they allow you to control many cameras conveniently and display them all on a monitor, without using a PC. They also come with many convenient functions that help you to centralize alarm detections, search video files and control the NVR via web. NVRs are equipped with an RJ45 network port that you can connect anywhere in your network, for example to a router or a switch. The NVR automatically detects all the onvif IP cameras you have connected to your network, both wired and wifi. If you want to see how easy it is, have a look at our video tutorial on the side.
Below is the scheme of a small IP video surveillance system: please note how the cameras are connected to a switch and not to the video recorder as you would do in traditional analog systems.
These NVRs allow you to display and control any onvif IP camera up to 5, 8 or 12MP resolution, depending on the NVR model. 2MP cameras (1080P or Full HD) are today the most popular in CCTV systems for their excellent quality-price ratio. 4MP and 5 MP cameras are used in high level CCTV systems where higher definition and zoom capability are required. 8MP (4K) and 12MP cameras are used to achieve the highest video quality in high-end security applications. These NVRs can handle cameras with different resolutions. Therefore, when designing your system, you can use different kind of cameras according to the importance of the area.
|Max. camera resolution||5MP||8MP||12MP||12MP|
The NVRs in this range support the latest H265 and H264 video compression formats, including the latest advanced versions, to get the highest performance out of any Onvif IP camera. If your cameras support H265, the most efficient codec available today, they will work great with these NVRs, recording high quality video stream with the minimum bandwidth requirement. Here, on the side, you can download two similar clips in H264 and H265 format: please note the difference in size and the similar video quality.
The video stream of any IP camera requires a certain data bandwidth. The bandwidth required by each camera varies, depending on the settings, from a minimum of 2 MB, for 2 MP cameras, up to over 10 MB, for 4K cameras . When you choose an NVR you must be sure that it can handle enough incoming bandwidth to receive all the cameras you will connect. The large input bandwidth, up to 350MB, is one of the main advantages of our RK NVR series, over low-cost, non-professional, products.
If you're looking for a high-performance NVR to record high resolution cameras without dropping a single video frame, this NVR range is just right for you. You can record 4K and 12MP cameras at 25 FPS and play back footage in real time. You do not have to worry about adjusting the video stream in the camera configuration because the NVR will do that for you. Check in the technical data table at the bottom of this page the top-notch performance of RK NVRs in live view, recording and playback.
You can buy our NVR for IP cameras with confidence. DSE is among the very few companies in Italy to be a member of the international ONVIF association that brings together the leading manufacturers in the field and set the communication standard between IP security equipment. Our NVRs strictly support the updated ONVIF standard, therefore YOU CAN USE THEM WITH ALL COMPATIBLE IP CAMERAS , of any brand.
RK Series NVR are very easy to set up. After configuring all IP cameras, each with its own IP address, you just have to connect the NVR to the network and use the automatic search function. The NVR scan your LAN network detecting all Onvif IP cameras of any brand. You just have to choose where to place the camera on the screen and press the ADD button. You can then take your time to configure recording policy, alarms and all other features of the NVR to best suit your needs.
The NVRs in this range are equipped with 2 monitor outputs: HDMI and VGA.
The HDMI port allows you to connect a TV or computer monitor up to 4K resolution (3840x2160) . If your CCTV system includes over 2MP (1080P) cameras, you will have great advantages in connecting a 4K monitor because it allows you to play back the full resolution of the cameras.
In addition to the HDMI port there is also a VGA port to connect PC monitors up to 2MP 1080P. These NVRs do not support low resolution analogue BNC video output. If you need BNC output you can use a VGA / BNC converter .
Please note that the HDMI video signal is not very strong. If you need to split it or transport it faraway, please use HDMI splitters and transmitters.
These network video recorders store video files on one or more internal hard disks. They can record continuously or only in case of intrusion. The NVRs come without any Hard Disk to let you choose the best disk size according to the required storage capacity. You can use any brand of SATA hard disk up to 8TB or 6TB capacity, depending on the model. Even ordinary computer hard disks work well, but for long durability special Hard Disks for video surveillance, such as those in our catalog, are recommended.
Thanks to the search functions, it is easy to find the important events in the video archive, scrolling the timeline. You can easily export video footages to be delivered to law enforcement. This backup operation can be done online with a computer, or by plugging-in a USB pendrive into the USB port of the NVR. Video files are exported in a standard AVI format and can be played with common video players such as VLC.

These NVRs can analyze the video captured by the cameras and generate alarm actions if an intrusion occurs. This function is commonly called MOTION DETECTION and is useful to save disk space by recording only when needed. You can adjust detection area and sensitivity for each channel. You can even set motion arming/disarming periods with a weekly scheduler. In case of an intrusion you can start recording and receive emails and notifications on your mobile phone. You can also save videos on web cloud servers to secure the recorded footage.
Through the NVR you can control movements, zoom and functions of PTZ motorized IP cameras. You can move the cameras with the mouse of the NVR but also operate via the Internet from a PC or a mobile phones. In IP systems, PTZ cameras does not require additional cables as all controls travel through the network cable, via the Onvif protocol.
Some models in this RK range have an audio input and output to which you can connect a microphone and a loudspeaker . When you get connected to the NVR, via computer or mobile phone, you can talk to the people in front of the camera to provide instructions or warnings. It is a convenient function in many industrial applications and also in residential surveillance, to monitor elderly or non self-sufficient people.
RK Series NVRs record on their internal hard disk until they run out of space. Once the memory is full the NVR automatically overwrites the oldest files. In compliance with privacy regulations it is possible to limit the number of days to be kept in the archive. If you need to set privacy masks, to obscure sensitive areas, remember that in IP systems this should be done in the cameras and not in the NVR.
RK series NVRs are packed with features but yet easy to use and configure with the on-screen menu. These NVR do not have buttons on the front panel, because all operations can be done with the supplied mouse. You can WATCH the live video of all the cameras on the screen and CONTROL PTZ cameras. You can CHOOSE among several display modes and ZOOM IN by dragging the mouse. The OSD menu allows you to CONFIGURE all NVR options and PLAY BACK the recorded videos, searching by date and time. You can also EXPORT AND DOWNLOAD video files on USB pendrives in AVI format.
Every computer on the network is a perfect monitor for your NVR. No software needs to be installed. Just open the Internet Explorer browser and enter the login password to WATCH the live video of all the cameras on the screen. You can RECORD , take snapshots and ZOOM IN by dragging the mouse. A user-friendly menu allows you to CONFIGURE all the options of the NVR from a computer and PLAY BACK video footage searching by date and time. You can also DOWNLOAD the video files on your computer in AVI format. These devices also support RTSP protocol that allows you to watch live view with ordinary RTSP players, like VLC.
With our free DSE APP for Android and iOS, you can control your cameras with a mobile phone or tablet. You can use the app over your own wifi network, by typing the IP address of the NVR, but also via the Internet, typing in your CLOUD ID. You can WATCH up to 16 cameras live on the screen. You can RECORD , take snapshots and ZOOM INwith the classic two-finger gesture. You can also PLAY BACK online videos recorded on the NVR's memory, searching by date and time. If you enable motion detection, you can RECEIVE push notifications on your mobile phone if an intrusion occurs, with a snapshot of the event.
You can control your NVR over the Internet in a matter of minutes with our free cloud server. Each NVR has its own ID number and is registered on our P2P cloud server which you can use without any limits. Thanks to the PEER-TO-PEER (P2P) technology, you can connect over the Internet in seconds, even if your Internet connection does not have a static IP and you have no need to modify the router configuration. The P2P cloud server allows you to use these NVRs also with 4G or satellite ISP. Using our cloud server is very easy: just download our APP IoVedo.RK, scan the QR-code on the NVR and you are ready to go.
These NVRs allow you to send out notifications in case of an alarm. You can send messages via EMAIL with the photo of the event and push NOTIFICATIONS to mobile phones with the IoVedo.RK app. You can also upload video files to FTP web servers. When you receive an alarm notification you should connect right away to your video surveillance system to check what is really happening.
These NVRs store video files on an internal hard disk. In addition, you can also save motion detection videos, on external cloud servers via the web. These NVRs support Google and Dropbox cloud services. Web cloud saving is useful to keep the videos safe in case the NVR got stolen or damaged. To use cloud storage, you need to buy a cloud folder from one of these providers and then bind your NVR by entering the connection details. Do not confuse cloud storage with our P2P cloud server for easy web operation: they are two different things.
You can use a computer to monitor and record cameras from many NVRs. It is useful to manage several CCTV systems on a central monitoring station. You do not have to buy anything, just download our free iVMS software that is suitable for all our RK series NVRs, DVRs and IP cameras. You can install it on as many computers as you like and use it freely, either as a main monitoring station or as an additional control unit. The iVMS software can manage as many NVRs as you need and show them in multiple custom screen layouts with up to 64 cameras simultaneously. iVMS supports our P2P cloud server so you can reach the NVRs over the Internet simply entering the ID.DOWNLOAD iVMS
If you are a software developer you can easily implement our devices in your projects. We provide you free SDK libraries to control all functionalities of our devices with your own software. If you need to get clean video stream for your software you can do that via RTSP protocol.DOWNLOAD SDK
Although an NVR can work well even locally, you will have great benefits from connecting it to the Internet. It's an easy operation with our app and it lets you control your cameras over the Internet, wherever you are. If you have an ADSL or Fiber Internet connection, you must connect your video surveillance network to a router port. If you do not have a wired Internet access, you can also use a 4G router with a data SIM to create a mobile Internet connection. Our P2P server allows you to connect via the web without any configuration with any type of provider, even via 4G, radio or satellite.
In addition to these NVRs, our RK range of video recorders also includes the DVR versions for analog AHD cameras. Our DVRs with BNC inputs are actually hybrid systems that can handle both analog and IP cameras together.
If you already have an analog surveillance system, with AHD cameras or old CVBS cameras, you can make it work with new IP cameras thanks to these devices. The RK Series NVRs and DVRs share the same graphics, programming menus, apps and software.
