An electronic gate system that monitors staff attendance and controls access is developed in this paper. This is because an electronic gate system is one of the means to curb staff inherent lateness to work and also control access within the vicinity. The system recognizes when a staff resumes or leaves before the stipulated time; this enables it to detect when a staff default. Facial recognition technology based on template matching with Open CV library is used for identification. This is developed into a standalone software application using C# (C sharp) programming language and an SQL (Structured Query Language) server database for storing data of valid users. Incremental software model is employed in developing the software. Access control functionality is also achieved by integrating an Atmega328 microcontroller mounted on an Arduino Uno board, a load cell and solenoid locks. High identification accuracy and a fast response time has been achieved when 10 staff, 5 visitors and 3 strangers were incorporated to test the system. The proposed system seeks to discourage lateness to work by including a penalization system for defaulting staff members and ensures this is done transparently to avoid litigations. More so, it enhances the security of any organization where it is installed since it will only grant access to legitimate users.

How the availability of private security services assist in crime control in Nairobi County, Kenya (Published)
The study was motivated by the fact that despite the presence of private security companies and the availability of their services in Nairobi city, there was still an upsurge of insecurity. This study was informed by Situational crime prevention and Crime prevention through environmental design theories. Descriptive survey research design was used, and the study utilized stratified random sampling technique to select respondents from the study population which was 500 respondents. Data were obtained using a combination of a questionnaire and interview schedule. Copies of the questionnaire were administered to 151 respondents, who were drawn from the private security companies in the area of study, and the members of staff working in the private institutions and also the area residents. The study was carried out in Karen location which is an upper market estate in Nairobi County. The study identified five categories of crime control services provided by private security companies, with providing alarm response and loss prevention being the major crime control service. The study further found that majority of the residents in the study area goes for the medium level security premium which offers alarm response and security guarding services. Findings revealed that a majority of respondents (52%) perceived the level of effectiveness by private security companies to be fairly moderate, 28% perceived them to be average and 20% of the respondents perceived them to be good. Overall, private security services, were perceived, to be relevant in crime control in Karen location.
