Hikvision’s new DVR and NVR series, both based on a Netra platform, provide dual self-adaptive gigabit network interfaces to benefit your video surveillance system. In terms of multi-address, load balance, network fault tolerance, etc., Hikvision has you covered.

A prime example is with multi-address; as before, due to single network interface, previous DVR/NVRs were only able to be connected to one single network. More specifically, two separate clients (or customers) in two dedicated networks (LAN/WAN) were not able access the same DVR/NVR units at the same time.

But thanks to dual network interfaces – with multi-address, two different IP settings can now be configured to allow network access from two dedicated networks. Hence, two different workgroups, from separate subnets, are able to access the same DVR/NVR and read video recording files or configure data onto the same system.(read more)…

Moreover, if network congestion, network outage, or various other connectivity problems affect one network; video stream data can still be read or written from an additional network throughout another interface. 
 
And, speaking of reliability: dual-gigabit network interface ability not only improves system reliability, but also ensures both seamless video recording with load balancing and network fault tolerance. Additionally, load balancing in respect to the bandwidth is also achieved. As such, optimal resource utilization, maximized transfer speed, minimized response time, and avoidance of overload by distributing workload across two network interfaces; while network fault tolerances allow the DVR/NVRs to sustain any possible failure on only one network port – thus providing continuous service and optimal performance to the user!
