CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
CCTV relies on strategic placement of cameras, and observation of the camera’s input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation “closed-circuit” to indicate that access to their content is limited by design only to those able to see it.
Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera’s associated speakers.
CCTV is commonly used for a variety of purposes, including:
- Maintaining perimeter security in medium- to high-secure areas and installations.
- Observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities.
- Traffic monitoring.
- Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments.
- Building and grounds security.
- Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports).
CCTV is finding increasing use in law-enforcement, for everything from traffic observation (and automated ticketing) to observation of high-crime areas or neighborhoods. Such use of CCTV technology has fueled privacy concerns in many parts of the world, particularly in those areas in the UK and Europe where it has become a routine part of police procedure.
Step 1: Earn a Bachelor’s Degree
While a bachelor’s degree in general computer science will suffice, many schools offer 4-year degree programs specifically in network or computer engineering. These programs provide an overview of standard industry networking tools and procedures for resolving problems within computer networks. Classes cover topics like operating systems, programming essentials, network administration, and information security. Students may also gain instruction in specific networking systems, like Cisco.
To get the most out of your degree, complete an internship. Experience is essential to entering this career, and so aspiring computer network engineers may benefit from completing internships to gain practical experience in the industry. In fact, some bachelor’s programs offer internships to network engineering students. Some individuals may find that their schools instead offer cooperative learning experiences, which similarly allow the opportunity to gain hands-on experience while earning college credit.
Step 2: Work as a Network Administrator
The U.S. Bureau of Labor Statistics (BLS) reports that many network engineers are promoted from network administration or other similar IT positions. Network administrators mostly focus on installing, maintaining, and monitoring the performance of networks, as well as overseeing IT support specialists, and they may assist engineers in the network design process. After earning at least five years of experience and demonstrating proficiency in networking, these workers may advance to network engineer status.
You can also choose to earn industry-standard certifications. Software vendors such as Microsoft, Cisco, and Red Hat offer certifications to network administrators who use their products after passage of an exam. Possessing one of these certifications may enable individuals to advance in their careers faster, and some employers even require administrators to be certified in specific programs.
Step 3: Consider Earning a Graduate Degree
The BLS notes that some employers favor network engineers who possess graduate degrees, such as an MBA with a focus on information systems. These MBA programs typically last 2 years and combine instruction in business topics with instruction in IT concepts. Master of Science in Computer Networking degree programs are also available. These programs include classes in wireless networking, telecommunications design, and Internet protocols.
To recap, with an undergraduate degree in computer science, information systems, or computer engineering and experience as a network administrator, computer network engineers can earn about $100,000 a year to plan and construct LAN and WAN network systems.
Cisco Certified Network Associate or CCNA is one of the most commonly pursued technical professional certifications. It is also consistently ranked amongst the most well paying certifications. No wonder there are more than 1 million Cisco certified individuals making their mark in the corporate world. Out of these a majority of individuals are CCNA certified. With more and more companies depending on the computers and the internet for running their business operations, it is essential to keep their computer network infrastructure in good shape and running all the time, and also keep it safe from the hackers. CCNA certified individuals are trained to ensure the same. Since Cisco is the biggest manufacturer and supplier of network devices in the world, it makes sense to get trained in configuring, and troubleshooting CISCO devices.
The career opportunities after CCNA certifications are many, right from small companies to major corporations and even in the public sector. First of all, one can applyitself after successful completion of their certification. One can also apply to other positions such as network administrator, IT support executive, and Network Security Analyst amongst others. If getting a job is your main priority after completing CCNA certification then you should start browsing big job sites like Naukri and Monster weekly right before you complete it. It will give you the perspective of the different kinds of opportunities that this field has. The salaries offered to entry level professionals is around 3.5 lac per month in India Rupees or if you are in a foreign country it could be around $50,000.
CCNA (Cisco Certified Network Associate) is a category of technical certifications offered by Cisco for early-career networking professionals. The CCNA is the second level of accreditation, one step above Cisco Certified Entry Networking Technician (CCENT) and directly below the CCNP (Cisco Certified Network Professional). Cisco offers five Cisco Career Certification programs and levels of accreditation: Entry, Associate, Professional, Expert and Architect.
Cisco redesigned the CCNA program in 2013 to offer the certification in various subspecialties related to networking. For example, the CCNA Cloud certification focuses on the skills required for cloud networking, while the CCNA Wireless certification validates an individual’s competence in wireless local area networks (WLANs).
CCNA certificates are available in the following ten areas: cloud, collaboration, cybersecurity operations, data center, design, industrial/IoT, routing and switching, security, service provider and wireless.
The CCNA routing and switching category is the most similar to the pre-2013 CCNA program. A CCNA routing and switching certification covers the fundamentals of enterprise networking, including LAN switching, IP addressing, routing, subnetting and more. It assesses an individual’s ability to deploy, configure, manage and troubleshoot enterprise networks. In 2016, Cisco updated the CCNA routing and switching certification to place more emphasis on software-defined networking (SDN), network-based analytics and network functions virtualization (NFV).
The Microsoft Certified IT Professional (MCITP) certification is one of Microsoft’s new generation of credentials that provide IT professionals with a simpler and more targeted framework to display their technical and professional skills.
