These pins include input/output ports such as PORTA, PORTB, PORTC, PORTD, PORTE and two Vdd ports for input voltage. The PIC architecture is characterized by its multiple attributes:Separate code and data spaces Harvard architecture. A small number of fixed length instructions. Most instructions are single cycle execution, with one delay cycle on branches and skips. All RAM locations function as registers as both source and destination of math and other functions. A hardware stack for storing return addresses. Data space mapped CPU, port, and peripheral registers. The program counter is also mapped into the data space and writable. There is no distinction between memory space and register space because the RAM serves the job of both memory and registers, and it is usually just referred to as the register file. The keypad:This device is used to enter the password selected by the user and to arm or disarm the alarm by selecting the various profiles installed in the system. As you can see from our project’s picture we used a 4 x 4 keypad, as instructed by Dr.

 

 

home monitoring services

home security monitorsThe reverse is true of an interior siren; however, the sound level will not be very pronounced outside of the home. The advantage of having audible sirens, whether the sound is louder inside or outside, is debatable. On one hand, the siren lets intruders know that police have been alerted, which may deter them from taking any further action, while some intruders may still proceed. Audible exterior sirens are also beneficial if you live in a populated neighborhood with neighbors close by, as they will hear the alarm; however, the audibility of the siren may be marginally beneficial if you live in a remote area where neighbors’ homes are out of range. Many of today’s security cameras have something called a motion detector installed. This is—as it sounds—a device that’s capable of detecting movement.

What kind of motion it detects depends on the user’s custom settings. In the case of a home security camera, this will typically include any moving objects, and people in particular. The great feature of motion detection home security camera is its ability to send alerts the second it begins to record movement based on its settings. One of the great things about motion detection is that your camera still works for you in the background even when you’re away or logged out of the system. The best way to understand how motion detection works is to first look at how a camera functions. Inside every camera is the image sensor which the lens of the camera directs light to.
