What makes a CCTV system really useful is a good and reliable digital video recording system. For an IP CCTV system, nothing is better then a Network Video Recorder (NVR)
The DN series NVR's are suitable to all DSE IP cameras and make IP CCTV systems very simple to manage. They are also compatible with other IP camera brands, if they support the ONVIF protocol, nowadays a well known international standard.
DN NVR's record IP cameras at HD, Full HD, 3, 4 and 5 Megapixel resolution. All products in this range are 100% real time NVR recording at 25 f/sec each channel in any condition.
DN NVR include the latest CLOUD and P2P technologies.
Our CLOUD servers are available on-line to make the remote control of your NVR via Internet as easy as possible, without the need of DDNS or router port forwarding.
The powerful APP for smatphone, free to download on Apple Store and Google Play, allows the total control of your NVR while you are away from home.

  Why using NVR for IP cameras?

Many DSE IP cameras are able to record videos directly on PC or SD cards and come with all the necessary software. Therefore, an IP based CCTV system can work smoothly without an NVR.
On the other hand, DSE NVR make installing and using IP systems much easier because the configuration of the cameras and the bandwidth adjustment is done automatically.
Besides, NVR provide VGA and HDMI monitor outputs to connect any kind of display.
DN range NVR are inexpensive and they are very stable and reliable for 24/7 surveillance. They are user friendly and rich of networking features to make the connection over the Internet as easy as ever, without requiring static IP, DDNS or port forwarding.

IP scenario  

DSE NVR are compatible with other manufacturers IP cameras which support the ONVIF standard protocol. You can integrate old IP cameras in the new system with ease.

  Main technologies

ONVIF protocol
onvif members ITALY IP camerasAll DSE NVR communicate with IP cameras using the ONVIF protocol.
ONVIF is a very important international standard in the IP video industry, resulting from the cooperation among the most important manufacturers. Thanks to this protocol, you can use your NVR with DSE RH range and RK range IP cameras but also with any other camera brand which support this standard.
DSE is one of the very few Italian companies being member of ONVIF (see ONVIF MEMBER LIST). Only ONVIF members have the tools to test the full product compliance to the most updated ONVIF standards.  Please bear this in mind when you are choosing your IP surveillance provider.

HDD video recording
Like all digital video recorders, NVR store all the video files on built-in Hard Disks, the same kind of memories used in Personal Computers. In order to provide the maximum flexibility, DN video recorders are supplied without hard disk.
Up to 2
SATA Hard Drive of any brand and up to 4TB capacity can be installed, in order to tailor the recording capacity to your actual needs.
Compression can also be adjusted to match your storage requirements. As a reference, considered that 1 hour recording of 1 2MP camera takes an average of 200MB at the maximum resolution and frame rate.

Up to 5 Megapixel resolutiontelecamera 5 megapixel
Using state-of-the-art capture chips, the DN NVR range records IP camera up to  5 MPX resolution (2592x1920 pixels).
Obviously these NVR can also control lower resolution cameras like HD 720P (1280x720), FULL HD 1080P (1920x1080), 3MPX and 5 MPX.
The max. frame rate for each channel is 25 f/sec which means 100% real-time. 25 f/sec is the movie standard. At that speed the human eye cannot realize that the video is made of many single photograms. DN NVR will always provide real-time videos, without any noticeable  lagging or latency, even when the target is moving  fast in front of the camera.
Very few NVR on the market can control such a wide range of camera resolution in real time and this make this range suitable for highest security level CCTV systems.

Minimum video latency
One of the main benefit of using a DSE NVR in your IP CCTV system is saying good bye to video latency.
Well known among the owners of IP cameras, video latency  is the delay between when things happen in real time and when you see it on your monitor.
With DN range NVR you do not have to worry about managing the bandwidth or adjusting the video streaming in the camera settings. The NVR do that for you and display just clear, real-time videos, without any noticeable latency.

Automatic IP camera search and install
DSE NVR are very easy and convenient to install.
No manual setting or difficult configuration is required. Just connect the NVR to the network and it will automatically search for all available ONVIF cameras. Once completed, the search results are listed on the NVR monitor.
Now you just have tp choose the video resolution and connect the cameras to the NVR channels as you wish.
Installing a DN range NVR is not more difficult than setting up one of our analogue DVR and takes about the same time. If you are attracted by IP CCTV but afraid of difficult settings, you will be surprised how much these NVR make your job easier.

Touch keypad
First in the market, DSE designed for the DN range a new exclusive touch keypad.
Unlike traditional pushbuttons, touch-keys never wear out by the effect of dust and use.  Besides, the touch keypad has a clean, elegant design and is very convenient to keep clean.

Networking with Internet Explorer
DN video recorders come with an RJ45 Ethernet port for direct connection to a switch or router.
You can control your NVR from a remote PC using nothing more than the Internet Explorer browser. You can enjoy live view of the cameras, playback recorded videos, control your PTZ cameras, and set up  the whole NVR configuration.
