This reliable Electronic Security system can be used in banks, Factories, Commercial establishments. The system comprises two monitoring systems, one is a light detecting system and other is a Loop sensor. When a light falls on the LDR (Light Depending Resistor) then the system generates an alarm sound, and when the loop wire gets opened at any condition then the alarm is switched on. The above system is monitored and controlled by the 8 bit microprocessor 8085A and using the Ports of 8255. The Microprocessor continuously monitors the Loop wire and the LDR through the ports of 8255. if there is an abnormal condition is detected then the alarm is switched on until the fault is cleared. The monitoring for Microprocessor is done by the PPI (Programmable Peripheral Interface) IC8255.

That was very rational. When deciding to put up security cameras, determine first the areas you’d like monitored. This gadget could be quite expensive if you’d put up one unit in every corner of the house. The key to such problem is proper angling. Home safety is paramount, that’s why it is really good news that home security cams are more affordable now. Having a secure home wouldn’t then be at all impossible for some people.
