alarm home security system

Our design for a functional keypad was the usage of an alternation of ports between inputs and outputs which is done by using the TRIS function. We started off by setting the first four ports of PORTB as the inputs and the latter four ports as the outputs. The first four ports are connected to the columns meanwhile the last four are connected to the rows. Moreover, as a justification for this reasoning is the fact that it is required to scan the columns for the pressed key and then scan the rows and the results will be decoded in a decoder telling us which button of the keypad was pressed. The main functionality of the keypad as mentioned earlier is to set the code. The alarm can be armed and disarmed with a standard four digit user code in our case. The master code is a step above a regular user code. It is used to unlock the system, as well as programming or erasing a regular user code. Theoretically it can also be used to bypass some sensors. The default password set during the design, which is also the installation code, is 1234. Most alarm companies use the same installer code for all of their installations, and the vast majority will never give their installer code to a customer, for obvious reasons.

Yes. As home automation becomes a bigger part of many people’s lives, home security providers are updating their equipment to fulfill the demand. The Nest Secure and Vivint’s Smart Hub, for example, not only function as the brains of your security system, but also as hubs for home automation. Most home security companies also offer smart devices — like locks, garage doors, and doorbell cameras — that pair with their systems and can be managed through their apps. And if your security system doesn’t operate as a smart hub, you may sync with third party smart hubs that let you manage both security and non security related devices on a single platform. Many surveillance cameras and audio bugs emit radio waves and can be identified by a standard RF radio frequency detection device. Conduct a “sweep” of your home with your bug detector. Surveillance devices are often hidden in walls or ceilings, so look for any spots that appear to be spackled or recently concealed. However, with the decreasing size of surveillance equipment, illegal surveillance can be concealed virtually anywhere. Household objects such as pens, clocks, lamps and even watches may contain devices to see and hear what you are doing. Closely examine your home's windows, as the exterior of windows are excellent places for installing illegal surveillance devices since no one has to break into your home to install them.
