DVR Video Management System

Cameras connected to the same DVR are not necessarily managed by the same person.

In a four-story building, for example, Manager A may oversee the first two floors while Manager B oversees the third and fourth. All cameras may connect to one DVR. If access can only be granted to the entire recorder, it is difficult to reflect those responsibilities: broad access exposes unrelated areas, while tighter restrictions can obstruct work.

Across multiple sites, managers need more than access to video. They need a centralized interface that assigns viewing rights according to actual responsibilities.

We developed separate DVR video management systems for a major nationwide financial institution and a Taiwanese electronic components manufacturer. Both projects addressed a shared challenge: making existing surveillance equipment fit the way the organization is managed.

View multiple sites through one web interface

We integrated video feeds from DVRs at different locations into a web interface. Managers can view live footage from the office and switch between 4-, 9-, and 16-view layouts without visiting each site.

For staff monitoring several locations, split-screen views bring the feeds together. Video previously scattered across recorders—from different floors to different facilities—now has a common point of access.

Control permissions for each camera

Viewing permissions are defined at the camera-channel level and aligned with the organization’s management hierarchy.

In the floor-management example, Manager A can access the first and second floors while Manager B can access the third and fourth, even though all cameras share one DVR. Permissions follow responsibilities rather than recorder connections.

Both the financial institution and the manufacturer use this capability to provide the footage each team needs while avoiding unnecessary access to other areas.

Review recordings from the same interface

Alongside live viewing, users can search historical footage by date and time, play it back, and download it for incident review and subsequent handling.

Recordings remain on the DVRs at each site. The system provides a unified search and operating interface so managers can move from observing current conditions to reviewing a particular time period in the same system.

Adapt management to the customer’s environment

The two customers had different account environments, so we used different integration approaches. The financial institution connects to existing centrally managed accounts, including synchronized deactivation. The manufacturer creates accounts within the system and manages users and permissions independently.

These arrangements make the move to a web interface more than a visual change. They also fit existing personnel-management processes and support changes in access when staff move or leave.

Align video management with organizational responsibilities

The value of these projects lies in bringing distributed video together while retaining detailed access boundaries. Managers can monitor multiple sites remotely, teams can view the areas they oversee, and incidents can be reviewed through a shared interface.

Starting with actual management requirements, we connected existing DVR feeds, organizational permissions, and operating workflows to make surveillance information easier to use in daily management.
