SINGAPORE - A padlock on the grilles?
That may become out of date soon, as more high-tech security gadgets make their way into ordinary households.
One security system that is gaining popularity in the home is the closed circuit television (CCTV).
Says Mr Jerry Wang, business development director of Rayguard Access control: "For small businesses, CCTV has been widely used to protect the assets of the company as well as monitor staff safety during office hours.
"But for the home owner, it is commonly used to monitor the domestic helper."
Users can view the real-time goings-on in their homes while at work or elsewhere.
Other gadgets - such as security alarms and digital door access systems, once only found in high security installations such as banking and government buildings - have also slowly moved into industries handing high value goods and storage, and into homes.
"It was only in mid-2005 or 2006 that they started becoming mainstream consumer products," says Mr Wang.
Alarm systems to deter and alert the presence of intruders typically comprise a control unit, an alarm panel and contacts and sensors on doors and windows.
Home owners can wire up their alarm systems to security firms that are on call 24 hours a day should any situation arise.
digital door locks typically require the users to key in an access code for entry.
In office buildings, the latest digital door locks make use of biometrics readers and radio frequency identification (RFId) card access, says Mr Alan Goh, business development manager at ASSA ABloY Singapore.
