Thanks to the ever-increasing popularity of IP networks, transmitting

video, voice, and data simultaneously over Ethernet/Internet are

becoming a standard feature at locations the world over. Because of

this, CCTV surveillance systems are also becoming more commonplace.

Versatile and advanced video digitizing and compression technologies,

such as MJPEG and MPEGx, make it possible to migrate CCTV

surveillance systems to IP-based platforms. This means that video

over IP solutions, which include IP cameras, video servers, and NVRs

(Network Video Recorders), are used by some of the hottest products in

the CCTV surveillance market. However, most video over IP solutions on

the market today are designed for general purpose applications, which

means they are not suitable for unpredictable industrial environments.

In fact, some seemingly commonplace applications, such as road traffic

control and monitoring, oil and gas refineries and pipelines, mining pits,

etc., should be classified as industrial-grade, and as such require using

rugged, well-designed video over IP solutions to ensure that the video

surveillance system works properly.

To meet these stringent requirements, Moxa’s new line of VPort

industrial video servers feature an industrial-grade rugged design and

extra-high reliability.

Products used in industrial environments must have a rugged design

to provide better protection against adverse conditions. In general,

ruggedized products should have the following characteristics:

1. Power Redundancy

A backup power supply is required since power lines used in harsh

industrial environments have a greater chance of failing. This means

that industrial products should have at least 2 power inputs to

provide sufficient redundancy.

2. Enclosure Protection

A rugged mechanism design means having good physical

protection against unexpected damage from external factors. The

Ingress Protection (IP) rating index (EN60529) is an international

classification system that rates the effectiveness of sealing

for enclosures of electrical equipment against the intrusion of

foreign objects (e.g., tools, dust, fingers) and moisture. The IP

rating system can be used to provide a better description of the

effectiveness of an enclosure.

3. EMI and Surge Protection

Compared to commercial-type environments, industrial

environments are more likely to be subjected to severe electrical

and magnetic influences. In order to protect electronic devices,

higher EMI and surge protection are essentials for industrial

applications. And for some industrial applications, safety

approvals and demanding certifications, such as UL508 and ATEX

(ATmosphere EXplosible), are also required.

4. High MTBF (Mean Time Between Failures)

The MTBF value is the “average” time between failures for a device.

A higher MTBF value indicates that a device is more reliable.

5. Wide Operating Temperature Range

The operating temperature range is also a key issue for industrial

products. In fact, some industrial applications require products that are

guaranteed to operate in temperatures ranging from as low as -40°C to

as high as 75°C. For these types of applications, it is important to look

for products that do not use a built-in fan, since products with fans tend

to have a lower MTBF.

6. DIN-Rail Mounting and Panel Mounting

A 35 mm DIN-Rail is used for many industrial applications to provide

a convenient means of mounting all of the devices used for the

application. For this reason, it is essential that industrial products

support both DIN-Rail mounting and panel mounting.
