Electronics

Electronics is distinct from electrical and electro-mechanical science and technology, which deal with the generation, distribution, switching, storage, and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays, transformers, resistors, and other passive components. This distinction started around 1906 with the invention by Lee De Forest of the triode, which made electrical amplification of weak radio signals and audio signals possible with a non-mechanical device. Until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers, and vacuum tubes.

Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid-state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineeringaspects of electronics.

Make an Educated Choice in Security Solutions

This is a growing market. Security incidents in schools grab the headlines, emotions and budget allocations. How to address security concerns leaves room for many opinions and strategies. Relationship selling past experience with school districts and government sourcing requirements make this opportunity a complex environment to grow your business. The key stakeholders for K-12 schools include school district management, parents, police and the students being impacted. Finding funding and getting more "bang for the buck" with innovative security solutions will separate you from a low price RFP market. Offering an alternative bid to what is specified and that offers more value is a smart business decision. Consider ZKTeco as a partner.

Solutions

• Phased conversion or expansion of security program
• Cost effective access control and time attendance solutions
• Teacher Student Roster Verification System
• Streamline access control processes for enrollment and record keeping
• Validated entry control The C-3 access control product line provides cost effective legacy migration for existing, older facilities that want to deploy ID access control measures to ensure visual credentials for authorized with access and have limited budgets for security needs.

Challenges

• Availability of funding for security
• Legacy security systems
• Physical building limitations
• Developing clear leadership consensus
• Diverse group of stakeholders
• Political realities of doing business
