A central recorder for larger surveillance systems
This recorder acts as the brain of your surveillance system. It brings together all the cameras, stores the recordings, and it’s also where you can view live footage, find events and manage the entire system.
Recording in very high resolution
The recorder can handle cameras up to 16 megapixels. That means you can use cameras with very high detail and still get stable recordings.
It can also decode multiple high-resolution video streams at the same time, so you can view live footage, play back recordings and have several cameras open without the system becoming slow.
Supports up to 16 cameras
The recorder can connect up to 16 IP cameras. That makes it suitable for businesses, institutions, warehouses and larger private installations.
All cameras are gathered in the same system, so you can view them together in a live view, either on a monitor connected to the recorder or via your computer or mobile.
Space for four hard drives
The recorder has room for up to four internal hard drives. This allows for very large storage capacity, which is important if you record in high resolution or want to keep recordings for a long time.
The system also supports RAID functions, which can provide extra data protection if a hard drive fails.
Stable recording even during network issues
The recorder supports ANR, Automatic Network Replenishment. That means cameras with SD cards can continue recording locally if the connection to the recorder is interrupted.
When the connection is restored, the recordings are synchronized automatically so no clips are missing from the history.
Advanced search in recordings
The recorder can use metadata and analytics from the cameras to make it easier to find specific events. For example, you can search for people, vehicles or particular types of incidents in the recordings.
That makes it much faster to find relevant clips, especially if you have many cameras and large amounts of video.
Live view directly on a monitor
The recorder can be connected directly to a monitor via HDMI or VGA. This makes it possible to use the system locally without a computer.
You can choose different layouts where multiple cameras are shown at once, so you quickly get an overview of the whole area.
Access from mobile and computer
You can access the system via mobile, tablet or computer. Here you can view live footage, play back recordings, export video and manage the system.
Multiple users can be logged in at the same time, which makes the system suitable for businesses and organizations.
Intelligent features via the cameras
The recorder supports intelligent features from the cameras, such as face detection, person analysis, vehicle analysis and various types of video analytics.
This enables advanced search functions and reports directly in the system.
Accessories
The recorder can be mounted in a rack cabinet using a rack mount bracket, which is often used in equipment or server rooms. In addition, you can add hard drives as needed, depending on how long you want to keep recordings.

ANR
If there are network problems, the camera stores the recordings on an SD- card - and then sends them to the recorder when the connection is stable again.
HDMI / VGA
You can then configure cameras, watch live views and search in recordings - directly on your NVR. It even comes with a mouse.

Hvor stor en harddisk skal jeg vælge?
Optagere leveres som udgangspunkt uden harddisk, for behovet er ikke det samme for alle.
Når du optager din videoovervågning, så er der flere ting der påvirker, hvor meget optagelserne fylder.
Helt oplagt så betyder antallet af kameraer, og deres opløsning meget - men din konfiguration, og hvor meget der sker foran kameraet, har også en betydning.
Udgangspunktet er, at man hellere skal optage en time for meget end et minut for lidt. Omvendt gider normalt kun nordmænd lave videoer, der viser at græsset gror.
Brug beregneren til at få en fornemmelse af dit pladsbehov. Synes du det er spændende, så læs lidt mere om pladsoptimering nederst på siden. Og har du vigtigere ting for - så bare ring til os...
1) Vælg kameraets opløsning...
2) Vælg antal kameraer...
3) Vælg størrelsen på harddisken...
4) Vælg antal timer med optagelse per dag... 6

24 timer
Resultat:
Lagringspladsen svarer til cirka timers videooptagelse.
Med 6 timers optagelse pr dag, kan du typisk gå dage tilbage i tid.1)
