System Overview
DHI-EVS7124D oers unparalleled storage technology. It is designed and
developed to meet the needs of medium-range to high-end IP video
surveillance applicaons. It supports 512 channels of IP camera inputs,
and 1024Mbps incoming/recording/forwarding bandwidth.
Combined with hot-swap power supplies, fans and hard disk drives,
the EVS oers real Enterprise Class availability. The EVS supports dual-
controller Acve-Acve mode, ensuring no video loss during main-sub
switch.This EVS is ideal for a wide range of applicaons such as public
safety, transportaon staons, government instuons, hotel resorts,
shopping malls, city centers, and nancial instuons, where demand
expansion exibility, high reliability and centralized storage management.
This EVS is compable with numerous third-party devices making it the
perfect soluon for surveillance systems with or without a video manage-
ment system (VMS). Its open architecture supports mul-user access and
is compable with ONVIF 2.4.
Funcons
Modular Design
All key modules are hot-swap and redundant configuration. Redundant
fans, redundant power, and multi-redundant design ensure stability. The
brand new design for disk carrier ensures good cooling, stability and
safety for hard disks.
Storage Extension Capacity
Local extension, connecting to expansion storage cabinet by mini SAS
interface. Extension storage supports redundant power and RAID.
RAID 0/1/5/6/10/50/60
Offering a balance between storage performance, storage capacity, and
data integrity, the EVS features fruitful RAID 0/1/5/6/10/50/60 for faster
and safer recording.
Dual-controller Hot Standby
There is a main controller and a standby controller (hardware redun-
dancy). The standby controller is always acve, and will automacally
take over the business when the main controller goes wrong.
In the Acve-Acve mode, aer standby-controller real-me transmis-
sion service is enabled, the standby server pulls streams and there is no
video loss during main-sub switch.
ANR (Automatic Network Replenishment Technology)
Video is recorded in SD card in IP cameras when the network breaks
down, and aer the network is recovered, the video will be transferred
to EVS and then recorded on it.
