To help protect your home and family, consider installing a wireless infrared home security system. While no one likes to think about their home being broken into, the fact is a burglar can strike any of us—at any time. Even if you live in a low crime neighborhood, that doesn’t stop thieves from targeting your home. No security system is perfect, but having no security system makes your home easier to break into than a home with a system.
Hidden surveillance cameras can be very beneficial, especially if you have a babysitter or nanny for your child. These surveillance cameras are built into ordinary devices such as smoke detectors, alarm clocks, home security sensors, and many more. Hidden surveillance cameras are camouflaged so well that no one will ever know they are being video recorded. The only way to know for sure how your child is being treated while your away is with hidden surveillance cameras.

max security with Rolling Code TX and Shock Sensor with variable sensitivity
the alarm module can be assembled in only 2 hours and it don't need manual preset
with this characteristics is the most cheap system and the total cost could be reduced using a normal external sounder (escl. AG8)
GSM module will be add in the future for a remote control
Introduction
This project born to protect my house.
Transmitters
All the functions of this Home Alarm system will be activated and deactivated by this little Rolling Code
transmitter show in the photo
The Rolling Code is the most secure method to transmit data and reduce risk of scan.
With this method the serial number of any transmitter is stored in the receiver at the learning time.
This serial number is composed by many bits so to find it with a scanner it is impossible because it need many time.
Four button for these functions:
A) manual start of sound and light alarm
B) enable protection of the system
C) make a phone call (future characteristic)
D) disable protection of the system
External Sounder & Strobe
The AG8 is a microprocessor controlled external sounder with a built in strobe. It was designed for simple installation, and offers a wide variety of features and safeguards. Features include silent installation, and two flash settings, optional sounder settings (multi-sweep or two tone), selectable timer, simple testing, and diagnostic LED's that can be viewed after the covers are fitted .
·High impact polycarbonate moulding.
·Horizontal or vertical mounting.
·One standard built-in wrap around strobe lens.
·Double skin construction.
·NiCad back-up battery included.
·Multi colour options.
·Front and rear tamper.
·Two Piezo sounders.
·Dual tones.
Internal Sounder
ST-220: internal sounder with one piezo speaker
Internal signal
I use an internal red light like this one, fix up my door, to know if the alarm is active
Sensors
CTC047: magnetic contact for the door
IMPACTOR: a smart shock sensors for the door In built adjustable analyzer
Normal latching and non latching setting
Wide dynamic range of sensitivity with High-Low sensitivity setting.
Many of these components are easy to find in any electronic shop
The blue led connected to the pin RA3 of microcontroller is used like a memory to know if the alarm has been activated by an event and its reset after a reactivation.
The red led connnected to the power supply before the 1N5406 diode is used to check the power supply connection.
Offcource the other 3 microled red near the relais are used to check the output state.
HI-TECH Software has provided a freeware HI-TECH PICC-Lite compiler as a tool for hobbyists and students, but the licence allows its use for commercial purposes as well. It is ideal as a teaching tool for an introduction into the 'C' language and embedded programing on a Microchip device.

RFID Proximity cards are simple and easy to use; simply presenting a card to a proximity reader is quicker and easier than swiping it. Proximity cards and readers also do not wear with each punch because no contact is made with the reader.
Popularly called as swipe card attendance system is a 125 Khz proximity card attendance device which comes with proximity card based technology and powerful time attendance software. These are used to record attendance in offices and other institutions, also these devices can be used
Electronic anti-intrusion systems reliably detect anybody trying to break into a building and immediately trigger the alarm. If you want 24-hour surveillance, the system can be connected to an alarm monitoring centre.
Various products can be combined to design a intrusion and fire alram sytem such as Cctv, intrusion burglar alarm system, fire alarm system, automatic fire detection addressable & conventional
Biometrics : Fingerprint Attendance & Access Control device
Biometric products using fingerprint recogition technology are used as physical access control and attendance system. Insignia provides fingerprint or thumb impression technology as it is popularly know in India for the purpose of attendance marking at factories and offices. Fingerprint attendance helps to eliminate proxy punching and achieves to save on cost of employment.This technology can be used to provide secured access to offices, homes, lifts, Store room and Factories. fingerprint identification inthe most popular biometric identification technique.
