How Dahua Technology is meeting demands with MultiVision

International Security Journal speaks exclusively with Hertz Li, Alison Yang and Nan Zheng, Product Managers at Dahua Technology.

What motivated Dahua to develop the MultiVision series and how do these products address the needs of your customers?

Hertz Li, Product Manager (HL): The MultiVision series is primarily designed to help address the common pain points of our customers. One of them is insufficient field of view in some scenarios.

Traditional cameras with a fixed field of view may have blind spots and missing key information, making it difficult to monitor the entire area comprehensively.

Another one is single direction monitoring. Many traditional cameras can only monitor a single direction and cannot flexibly monitor multiple scenarios.

Poor linkage between multiple cameras is also a challenge with traditional cameras.

When multiple devices monitor large scenes, there is limited and difficult linkage between devices and the data generated by multiple devices is scattered and cannot be integrated for use.

In terms of value proposition, the MultiVision series offers a great deal of benefits to customers. For starters, it provides a seamless fusion and panoramic view of the scene.

The panoramic splicing series products typically consist of many traditional cameras, which is mainly to replace cameras with one device.

With panoramic splicing technology, this series provides a 180° panoramic view.

In addition, the MultiVision series has multi-directional cameras that support intelligent functions simultaneously, allowing for fewer installation points and adaptability to complex scenes, ultimately leading to cost savings.

Also, its X-Spans series products typically consist of an overview channel and a detail channel, which not only provide panoramic image and detail in one view, but also track the target for long distance, providing expanded views and clear details of the monitored scene.

Within the MultiVision series, how does the integration of multiple sensors, DSPs and lenses enhance functionality and performance?

HL: The MultiVision series is composed of security surveillance devices equipped with multiple sensors and lenses.

Compared to single lens products, the MultiVision series can capture more scene information and provide images with higher resolution, enabling broader monitoring in a given area.

Additionally, the MultiVision series supports intelligent applications in the same scene, such as integrating perimeter monitoring of large areas with structured analysis of detailed targets.

In comparison with single lens dome products, the MultiVision series does not lose scene information during target tracking, but can focus on panoramic and detailed views.

Furthermore, the MultiVision series relies on intelligent computing capabilities to provide functions such as panoramic-detail linkage capture and tracking, which cannot be achieved by single lens products.

In terms of performance, the MultiVision series offers higher resolution and provide a wider monitoring field of view.

In terms of functionality, it can achieve various intelligent functions such as multi-linkage, thereby providing more monitoring information over time.

In terms of intelligence, it can simultaneously enable multiple intelligent functions and provide different intelligent features.

Could you explain the difference between the Panoramic Splicing, Multi-Directional series and MultiVision X-Spans categories?

Alison Yang, Product Manager (AY): Their names say it all.

The Panoramic Splicing series achieves a panoramic 180° field of view coverage, which effectively solves the problem of traditional cameras not being able to cover the entire scene.

This series is mainly used in villas, warehouses, etc. The Multi-Directional series monitors multiple directions. Multi-directional products integrate two or more devices to expand the monitoring range.

They are mainly used in scenarios such as corridors and hallways. The X-Spans series combines a fixed camera and a PTZ camera to provide customers with overview and detailed channel.

The two channels can be linked; when a target in the overview channel triggers the rule, the detail camera will track the target. It is mainly used in courtyards, squares, parks and other scenes.

How do the product recommendations within the MultiVision series cater to different customer groups?

HL: In the MultiVision series, products can be categorised into channel-based products and project-based products to meet the diverse needs of different customer groups.

Channel-based products are suitable for a wide market and are typically provided by distributors or retailers to small and medium sized enterprises or individual consumers.

These products often feature user friendliness, reliability and competitive pricing.

They provide basic security monitoring functions and can be sold and distributed through various sales channels such as e-commerce platforms and retail stores.

Project-based products, on the other hand, are catered more towards large enterprises, local institutions or system implementation vendors.

These products usually require customised solutions to meet the complex requirements of individual customers.

Project-based products have higher performance, more powerful features and greater scalability.

They can be integrated with other systems such as access control and fire safety systems to achieve comprehensive security solutions.

By dividing the product recommendations into channel-based and project-based products, the needs of different customer groups can be met.

Channel-based products focus on providing simple and practical solutions suitable for small and medium-sized enterprises and individual consumers, while project-based products focus more on meeting the complex project requirements of large enterprises and local institutions.

Such categorisation also helps allocate resources appropriately and determine suitable market positioning.

Channel-based products are suitable for mass sales and distribution, with the aim of expanding business scale by covering broader market channels.

Project-based products require more customised and specialised services, focusing on establishing cooperative relationships with partners and customers to meet the needs of complex projects.

By categorising channel-based products and project-based products, the diverse needs of different customer groups can be better catered to and the product line can become more competitive.

What are some of the key features and advancements in the newly launched products within the MultiVision series?

Nan Zheng, Product Manager (NZ): The IPC Triple-sight Long Range Perimeter Protection Camera, Dahua’s pioneering perimeter professional camera, is specifically designed for long range perimeter protection scenarios, such as farm boundaries, solar power plants, enterprise park perimeters and more.

Featuring a triple focal lens, it ensures accurate target detection at varying distances for maximum security, with a detection range of 4-104m.

Illumination by area technology is applied to the supplementary infrared light, ensuring sufficient lighting for both distant and nearby areas to avoid insufficient lighting or overexposure.

The camera features a built-in micro motor, enabling remote adjustment of the vertical tilt angle for convenient customisation of the viewing angle.

A built-in gradient facilitates easy installation and levelling. With an IP67 and IK10 rating, this camera can withstand various harsh operating environments.

The STD4 camera is a MultiVision camera that integrates Dahua’s TiOC concept.

It provides customers with two channel images: An overview channel and a detail channel. The two channels can be used together or independently.

In the independent mode, the camera can be used as a TiOC duo camera and a TiOC PTZ camera with 25x optical zoom.

In the linkage mode, the panoramic and detail channels can be linked to achieve smart tracking.

What’s more, it has built-in red and blue alarm lights and speakers.

When a dangerous event triggers the alarm, it will activate the red and blue light alarm and sound alarm and track the target.
