Video walls can be an integral part of control rooms, enabling several sets of information to be shared across multiple operators and decision makers.
Video walls can improve:
Situational Awareness
Allowing operators to take in more critical information at a glance. Displaying multiple data feeds side-by-side gives context and improves situational awareness.
Seeing patterns and anomalies is simpler when data is visualised on a video wall as opposed to viewing isolated data feeds.
Response Times
By consolidating various data sources and visualising relationships between them, video walls empower rapid decision-making.
Insights from Data
A video wall expands the amount of data that can be visually monitored and analysed in real-time. This big data visualisation enables operators to gain more insights and make data driven decisions.
Improved Collaboration
A video wall provides a common operational picture that an entire team can refer to and collaborate around. Whether it’s daily monitoring or emergency response, video walls facilitate coordination between control room operators.
One of the key decisions is the technology that would be most beneficial for your particular control room. There are two main types of video walls - LED (Light Emitting Diodes) and LCD (Liquid Crystal Display). The choice depends on operational needs, budget and application. Both LED and LCD display types have pros and cons.
LED Display
Benefits can include:
- Displays on average have a significantly longer life span - around 10 years (~100,000 hours)
- Lower ongoing operator expense - maintenance is streamlined and can be executed through simple panel switching on “live” videowalls
- Wider angle viewing and seamless visualisation
- Unmatched brightness levels
- Lower power consumption (up to 40-50% lower than LCD)
- Can lower radio frequency interference
Disadvantages can include:
- More expensive for a given resolution and size
LCD Display
Benefits can include:
- More affordable for a given resolution and size
- High resolution, providing sharp and detailed images that is advantageous for close-up viewing
Disadvantages can include:
- Displays on average have a shorter life span - around 3 years (~30,000 hours)
- Narrower angle viewing, which can be limiting in larger rooms
- Pose a limitation where seamless viewing is required
- Higher power consumption
