Locksets which come under the doorknob assembly are available in differing levels of security and wide range and variety of styles.They can be bought from any of the hardware store (Lowe's, Home Depot).These locksets can be ornate in brass and can cost from twenty dollars upto three hundred to four hundred dollars.It doesn't matter which design or style of lockset is being used, the procedure of installing or removing them is more or less same.Most of these sets are easy to install and can be easily taken apart, especially those which you might have bought from a specialty or department store.Amongst the most secure and inexpensive locksets are known as Brinks Locks.Two basic locksets available are the spring latch and the deadbolt.Although spring lathes are much easier to install but the deadbolts are more secure.Deadbolt Locks. The knob outside has a keyhole while knob inside has the button for locking.1.Firstly, unscrew the inner knob.Usually it has 2 exposed screws; you simply have to remove them.Outside portion is free; inside half will pull off and hence by pulling it out, it can be removed.If you are not ale to visualize the screws, you should look closer and check for a small button along the shaft.2.Then remove the cover finding small notched opening.Then slip your screwdriver and pop off the cover.3.Remove 2 screws that hold the lock and the faceplate can be removed easily.Assembling the locksets. The procedure of assembling is the same as the dismantling but the only difference is that it is done in the reverse direction.1.Firstly insert the lockset in the opening from the outer side.2.Now, using 2 screws install the faceplate.3.Snap the cover along the bent wire latch which holds it in position.4.Then depressing the latch on shaft, slide the knob on the shaft.5.At last, check your lock by locking and unlocking it several times and make sure that the key should move freely.

Two security products have come to dominate the practice of screening people and possessions for possible risks or contraband.The X-ray scanning system and the metal detector are two technologies used throughout the security sector to screen entry to airports, prisons, banks and other VIP areas - and the chances are they are the only system that most people will have any familiarity with.The major benefit to these systems is one common to most technological solutions - they remove much of the scope for human error in security screening.In most of their applications, such as airport security, they also mean that large numbers of people can be processed effectively without compromising security protocols.In fact, these systems beat physical searches in terms of both convenience and capabilities.This isn't just because most physical searches are largely perfunctory and can also be massively disruptive, depending on the circumstance (imagine if everyone had to unpack and repack their luggage at the airport) but also because a physical search has to exhaust every possible hiding place one by one.With an X-ray machine, you can see both within bags and luggage as well as within the objects contained inside - and without ripping them to pieces.Items that appear perfectly normal in their outside appearance can often contain contraband or even explosive devices and when passed through an X-ray machine, these objects can quickly be identified by trained staff.Similarly, a metal detector can easily control access to a secure zone on an individual basis.Guns, knives, conventional explosives and other metal-rich devices are all impossible to sneak past a metal detector, no matter how well hidden they are.Even if someone was to surgically implant such a device - which is needless to say, an extremely far fetched scenario - they wouldn't be able to pass through a metal detector without setting off the alarm and drawing the attention of security personnel.These systems are so effective at security screening that the reality is that most of the time, they'll never actually detect a dangerous device (though X-ray machines at airports may often catch alcohol, tobacco or other goods before customs).This is because the only way to get around them is generally to avoid them completely, so they essentially act as a supreme deterrent and a near sure-fire way of catching those too foolhardy to be deterred.

A great way to avoid being robbed would be to take all the precautionary and safety measures that are available.For one, you can try to think as any professional burglar would.A burglar is still a human being.And like every human being, self-preservation is high on his list.This factor leads to the point that most professional burglars would avoid getting caught.And would not choose a house to rob with a high-risk of capture.And this needs to be your home.Certain amateurs will simply just smash into your home, grab something from the garage or enter through an unlocked door when you're not home.But the professional thief plans his robberies to minimize risk.They often approach the house by stealth and therefore most burglaries take place at the night.You should therefore light your home well and look out for those dark areas that could serve as points of entry - these also conceal any thief.Trim your bushes that thieves can use to hide behind.A visible perimeter around the house might put off any thief.And makes it difficult for him to access the weak spots.These kinds of weak spots depend on how the house is built and how nearby homes and the roads are situated.These points of entry would need a sturdy wooden or metal dowel for sliding glass windows.Yet that will offer no more than a few seconds of delay if your window can be lifted out of the frame.And it is simple and inexpensive to prevent that.You can just drill a small hole through the window frame into the wall frame that is holding it and insert a small dowel into the hole, or acquire a spring loaded mechanism from a kit that is similar to some screen door kits.Or talk to your carpenter and along with him take all steps to make it impenetrable.You can have a set of wrought iron bars in front of the windows or even have an alarm system that senses vibration or breaks in the glass.Another point is that burglars often rob a home which is empty, to avoid confrontation and to avoid any chance of capture.And yes, most burglars aren't necessarily murderers and would not want to add murder to their sentence if captured.So it would be good idea for you to have someone live in your home while you're gone.Now another important factor deciding the safety of your home is what your home holds.If a burglar is aware of extremely high priced valuables in your home, he'd be more than motivated to rob you.No matter what measures you take, a burglar might value your possession and think it is worth the risk.So make sure that what you have stays secret.Nothing will stop a professional thief who is the truly resolute, and has the right tools, but if you reinforce your home, they might likely to pick an easier target, especially if they don't know what's in there.
