The need for an effective and reliable intrusion detection system have become vital necessity because of the frequent and rampant cases of burglary. Attack on homes, offices, factories, banks etc. is on the increase. With the advancement in technology, motion can be detected by measuring change in speed or vector of an object in the field of view. This can be achieved either by mechanical devices that physically interact with the field […]

With recent dramatic development in the field of artificial intelligence (AI), smart access control has become crucial part of our modern everyday lives. This paper presents a door security system designed to prevent trespassing in a highly secure areas like home environment. The implemented system is cheaper and more reliable for intruder detection and door security. The door access is solely based on face recognition to ensure that o […]
ABSTRACT This work is on implementing the field strength meter. This device is a detecting circuit, the detecting unit consists of an antenna and a tune circuit which also comprises of a coil and a capacitor. The circuit picks up RF energy on its antenna and passes it to the tune circuit where all the frequencies, except one are lost in the coil. The only frequency to appear at the output of the tune circuit is the one that is equal […]
ABSTRACT This project work is on analysis of Electromagnetic Field Strength of NTA Port Harcourt, which operate at a frequency of: 210.25 MHz-Vision, 215.75MHz-Audio Channel: 10VHF, in Port Harcourt and its environs with the aid of an automated Band scanner GPS system. The measurements were carried out by taking the television station’s transmitter as a reference point at the center and selecting 24 measuring point around the transmi […]
ABSTRACT The study for the search of renewable sources of energy is now a major concern worldwide as replacement to the high demand of fossil fuels. Majority of the electricity that is generated uses the Faraday's law, the electromagnetic induction. This law led to new technologies that even brought up the misconception of free energy. Energy only becomes free if we don't have to pay for the generation of it; hence we resort t […]
