    The effectiveness of using a single or multiple camera CCTV (Closed-Circuit Television) solutions depends on various factors and the specific security requirements. Single Camera Advantages The main advantage is cost-effective, they are more budget-friendly initially. Managing and maintaining a single camera is straightforward. Limitations A single camera can cover a specific are and detect obstacles or incidents, it only provides a restricted field of view. Blind spots may exist. If it is not positioned optimally, it may miss critical events. No backup if the camera fails or malfunction. Deploying a single camera is cost-effective and generally a good choice if the application is small. Multiple Camera Advantages Multiple cameras can cover larger areas, reducing blind spots. If one camera fails, other continue monitoring. Different camera type can be strategically placed. Multiple angles aid in identifying individual or incidents. View different areas simultaneously on a single mo

    Cisco Meraki MX Firewalls is a Unified Threat Management (UTM) and Software-Defined WAN solution. As a UTM product, Meraki MX provides content filtering, app-specific traffic control, intrusion prevention, malware protection, and site-to-site VPN that is deployable on hardware or virtually. It also enables firewall management remotely for 24x7 monitoring and accessibility. Users are able to deploy, monitor, and configure their Meraki devices via the Meraki dashboard web interface or via APIs. Once a user makes a configuration change, the change request is sent to the Meraki cloud and is then pushed to the relevant device(s).   Meraki Cloud Architecture The Meraki cloud is the backbone of the Meraki management solution. This "cloud" is a collection of highly reliable multi-tenant servers strategically distributed around the world at Meraki data centers and select public cloud service providers. For the remainder of this document we will refer to both the Meraki data cen

  Kidde EOL-15 End of Line Resistor 15K Ohm The function of an end of line (EOL) resistor is to monitor the integrity of the circuit in a fire alarm system. This is achieved by placing the resistor at the end of the wiring loop, completing the electrical circuit. The control panel of the fire alarm system continuously monitors the resistance of the circuit, which should match the resistance value of the EOL resistor. Any changes from readings may indicate a potential issue, prompting the system to signal a trouble condition. An EOL resistor should always be installed as the last device in the loop and never inside the control panel. Placing resistors anywhere other than the end of the line does not serve a purpose. Open Circuit Detection When there is a break in the wiring or a device is disconnected, it creates an open circuit. This means that the electrical current cannot complete its path through the circuit, resulting in an increase in resistance. The EOL resistor, placed

I have a presentation to electronics engineering students in Iligan Institute of Technology – Mindanao State University, the title “ Fire Detection and Alarm System” or FDAS. Safety is a common word we hear in industries but some of the world seems to ignore this and the obvious reason was that the city enforcement of laws are weak. The goal was to spread the awareness on RA9292, the electronics engineering law inclusion to the National Building Code which is crucial to protect building occupants from harm and prevent damage to property. There are 3 important phases of fire detection and alarm system; the time element, notification (manual and automatic alarm) and activation. The idea of FDAS was to sense signs of fire and alert personnel to prevent fire from getting bigger. Why do we need FDAS when we already have some fire extinguisher?  To answer that question lets discuss the fire department response time. First the ignition where combustion starts and fire grows undetected

  Career Talk March 2 2017, MSU-IIT ECE Week (March 2-5) My good advice to students who wants to go somewhere else, other than the Philippines. Which direction are you going to take after college, or after you become an engineer or a technician? Most people will tell you to go overseas because the truth is there is no opportunity here. But what about your own family, friends that you care, favourite pets and the many places you enjoyed having fun for so many years. Are you just going to leave the place, for what – the money? Of course that is what most of us is up to and that is what we keep on focusing on – money. When we graduate, we accomplish one important goal that is to finish a degree on electronics engineering. There are lots of your seniors who took two licensure exam, one for electronics technician (ECT) and the other for electronics engineer (ECE). Well that’s fine and another good achievement of you if you make it. I urge everyone of you to keep on learning and sharing,

I was invited to be a judge for three students projects namely; a Solar-powered Hybrid Vending Machine, Smart Switch, and an Improved Mechanized Ice Cream mixer done by graduating electrical engineering students who participate on Iligan Institute of Technology, Mindanao State University – Innovation Convergence last August 30-31, 2016. The title of the event was 2016 Technnovation with the theme, “Advancing Technopreneurship and Innovation in Mindanao”. In parallel with other session they have these: Cluster 1 Resilient Structures, Disaster Risk Reduction and Management and Environment Cluster 2 Energy and Power Cluster 3 Health, and Pharmaceuticals Cluster 4 Food and Nutrition Cluster 5 Instrumentation and Control I am at Cluster 5 to judge the three projects, this is last August 31, 2016. The first one the Solar-powered Hybrid Vending Machine was very crude but I could understand that the students has to balance their budget with the idea of having an economically and portable v
