These DVRs are flexible multitechnology videorecorders, able to handle any analog or digital security camera on the market. You can connect any analog camera to the DVR's BNC inputs , from the old CVBS cameras to the latest 4K. If you disable some of the BNC ports, you will be able to add IP Onvif cameras to create a hybrid CCTV system with both coaxial and LAN wiring. With these DVRs you can not record digital SDI cameras, now out of production.
These DVR are 5-in-1 hybrid multitechnology videorecorders. They can handle 5 types of video signals.
The AHD signal is our standard format for high resolution analog video. It is today the most popular analog standard, providing very high resolutions up to 2MP, 5MP and above. AHD is an international standard so you can use one of our DVRs with any AHD camera, even from other brands. CVI and TVI , or TurboHD, are other video formats, very similar to AHD, but developed by other manufacturers. These DVRs handle CVI and TVI formats very well so they are suitable to all modern BNC cameras of any brand. CVBS is the old, low resolution, analog video signal and lets you control old analog cameras, even B/W. Finally, with these DVR you can connect IP Onvif cameras via the network port.
These DVRs are part of our RK range which also includes NVRs for IP cameras only and network 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.
With AHD (Analog High Definition) technology, the old low resolution analog video has retired. Together with our AHD cameras, these videorecorders provide all the megapixel resolution and remote control functions of our digital IP systems, but fully compatible with any existing coaxial wiring. Unlike IP cameras, AHD cameras do not require any configuration: they connect and work right away. This is why we recommend AHD technology if you look for a solid and easy to install CCTV system. If you want to know more about AHD, watch this video tutorial on the left that we recorded in 2014, presenting, as the first company in Italy, this innovative technology. Below you can see the basic scheme of a small AHD system.
These DVRs allow you to display and control any AHD, TVI or Onvif IP camera up to 8MP resolution (CVI up to 4MP). 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) cameras are used to achieve the highest video quality in high-end security applications. These DVRs 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. You can also keep using old CVBS cameras that you do not want to replace.
The DVRs 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 camera. H265 is the most efficient codec available today and allows these DVR to store almost twice video storage than H264 DVRs. If your IP cameras support H265, 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.H264 VIDEO H265 VIDEO
With our DVRs you can configure the video channels with maximum flexibility and do not have to choose between a few pre-configured options. The DVR is set by default with all BNC ports enabled. You can connect any camera, because the BNC ports automatically recognize the video format and resolution. If you disable some of the BNC ports, in the DVR configuration, a few digital channels for IP cameras are automatically added to your system. Look at the technical data table at the bottom of the page to see all the setup options of these hybrid systems.
In these DVRs analog and IP CCTV merge perfectly. If you already have a CCTV system on coaxial cable you can replace the old DVR with the new one without modifying your cabling. Just connect the camera cables and you will see the videos on the monitor. If you want to enjoy the advantages of digital CCTV, such as wifi , you can include IP cameras in a few seconds, because the DVR automatically detects all the IP cameras connected to the network, both wired and wifi. Once the configuration is complete, you will not notice any difference between BNC and digital channels.
You can buy our hybrid DVRs 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 DVRs strictly support the updated ONVIF standard, therefore YOU CAN USE THEM WITH ALL COMPATIBLE IP CAMERAS , of any brand.
The DVRs 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 the resolution of your cameras is over 2MP (1080p), 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.
Please note that the HDMI video signal is very sensitive. If you need to split it or transport it faraway, please use HDMI splitters and transmitters.
These digital video recorders store video files on one or more internal hard disks. They can record continuously or only in case of intrusion. The DVRs 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 capacity. 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, just 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.

Although a DVR works well without Internet connection, you will have great benefits from connecting it to the WEB via your router. 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 Optics Internet connection, you must connect your video surveillance network to a router port. If you do not have a wired Internet access, you can use a 4G router with built-in data SIM to create a mobile Internet connection. Our P2P server allows you to connect via the web with any type of provider, including 4G, radio or satellite ISP.
The channel configuration of these DVRs is very flexible. You can mix analog and IP channels as you like, to perfectly suit your needs. If you have an analog CCTV system and want to gradually upgrade to IP, you can easily do that. You can continue to use your old analog cameras connected to the BNC ports while gradually opening new IP digital channels for the new IP cameras. When you replace an analog camera, simply disable its BNC input port to have new IP channels available. If you disable all BNC ports, your DVR becomes a pure NVR, to control a purely digital IP CCTV system.
