Investing in an environmental monitoring and control systems is a way that you can ensure the protection of your assets, no matter where you are. Over the last 16 years, Netshield have developed and designed a range of point of presence, convergence gateways and with the addition of sensors and SNMP or cloud dash boards  you can remotely monitor and manage your environment across multiple applications from your home to your business.

Within datacenters & sensitive environments various services are required to ensure that the environment is monitored to ensure quality of service for the networking, server and storage equipment housed. These systems include environmental monitoring, power feeds, air conditioning, fire protection, security and access control into the datacenter.

Most vendors offer some of these services but all these services are not consolidated into a single management platform, this then required a manager of managers to consolidate these services into a single managed platform.
All these infrastructural services can be managed from a single hardware platform as the services are and events occur at a relatively slow rate, but when something does go wrong extremely quick predefined automated reaction is required. The quickest type of reaction is always based on a hardware layer decision, backed up with triggers that launch firmware processes that initiate messaging to the Network Management System.

Our use cases include:

1. Door status detection
2. Actuator door locking mechanism
3. Temperature, humidity sensing & Fluid detector
4. Monitored Type 1 & 2 surge protection
5. Air conditioning control interface
6. Serial UPS control and management
7. SNMP stack, trap, polling and walk
8. Power switching (up to 100Amp)
9. Wiegand base manageable remote controlled  access
10. Preemptive event management
11. Customized snapshot point of presence dashboard
12. Network Management Software: event correlation, automated 13. reporting and multi zoning SNMP or Cloud based
14. Self-Contained Cabinet design
15. Fire detection
16. Solid state fire extinguisher
17. Wan isolation and protection
18. Class 1 energy metering (RS485 MODBUS)
19. Lighting and Surge event counter (RS485 MODBUS)

Used for monitoring and control as a standalone unit to interchange the switching of the air-conditioners at a predetermined interval, monitor air-conditioner power and environmental conditions : temperature, humidity, water flood detection and air-flow . Smoke detector with controller for ventilation fan and airflow shutter.

On detection of transgression or variation of user defined preset threshold conditions the NACCUMON senses problematic conditions and delivers an alert via a SNMP trap notification to the appropriate event manager’s monitoring station. The remote management information system alerts and indicates any of these environmental problems to trigger immediate action for prevention or recovery of failures. The NACCUMON can also trigger alerts for preventative maintenance.

The NACCU dual air-conditioner and monitor unit can be connected to two separate air-conditioners.
• The air-conditioners can be monitored and controlled by the NVIROMON or a smart PDU.

• The NVIROMON or smart PDU is REMOTELY configured, controlled and monitored by the Netshield Monitor
One SNMP based management information system.
• When power conditions exceed pre-set thresholds, the NVIROMON or smart PDU senses the problem and delivers
an alert notification to the appropriate event manager’s mobile phone. The remote management information
system alerts and indicates any of these power problems to trigger immediate action for prevention or recovery of

Why outsource the building or expanding of your data centre? With increased devices – as we have all come to realise – comes increased data, which needs to be stored and used in a way that will benefit the business.

Many businesses prefer to store their own vital corporate information as it feels more secure and what this will often call for, is the extension of existing infrastructure or building of new data centres in the business. But can you rely on your IT team to build a data centre environment that’s right for your business? The problem that comes in when relying solely on internal IT teams to manage the building of new data centres or extension of existing infrastructure, is that they are so often focused on keeping the lights on that they may not have the up to date knowledge and expertise to build an environment that meets your business needs at a price you can afford.

The building of a modern data centre incorporates many considerations. With a project like this there needs to be a perfect balance between time, scope and cost –the Triple Constraints of Project Management notion – for it to be successful. Your unique business requirements regarding things like storage, security and pricing need to be considered. You also don’t want your IT team to be roped in by IT suppliers who may be biased toward a certain product or brand as this could result in the dreaded vendor lock-in. When it comes to the modern data centre what most businesses need is the perfect combination of stability and flexibility. You need to know that you have the technology to keep the lights on, but at the same time will not hold you back from innovation.

Now what if you could recruit an outside team of experts that could build or expand a data centre based on your specific business needs from floor to ceiling, with a vendor agnostic approach and that will keep you in the loop at every stage from the inception stage to close out? Well, Netshield has that team. You can rely on the Netshield Consulting Services team, with its over 32 years’ experience in the ICT industry, to provide you with affordable, agnostic ICT and Electronic Consulting Services for your end-to-end data centre needs.

Our Consulting Services division will design and build your entire data centre and all aspects around it from flooring to cooling to access control, security and more, on your behalf, while also consulting you at each stage of the process to ensure you happy with the way things are going. The Netshield ICT & Electronic Consulting “built environment” life cycle has six stages including inception, concept and viability, design development, documentation and procurement, contract administration and inspection and close out. You will be involved at each stage, but simply to give your approval, our team will handle all the work.

Due to client demand we have also developed a range of consulting packages to meet specific client needs including Align IT, Secure IT, Architect IT, Design IT, Strategise IT, Continue IT and Manage IT. And to top it all off, we offer ICT project management services to ensure that time, cost and scope are in equilibrium in the project to ensure its success.

There’s a saying that it’s better to work smart, not hard, and that’s exactly what you will be doing if you leverage the Netshield Consulting Services team to build or extend your data centre.
