Proper access control can keep criminals out
One of the major contributing factors of crime in especially high rise condominiums or flats is inferior access control or in worse cases no access control at all. There is a scripture that says: He who has no rule over his own spirit is like a city broken down without walls. This will apply perfectly to a building with no access control. Just like an ancient city was defenseless without its strong and high walls likewise a modern building without proper access control is a building that invites criminals into its corridors. Fortunately there are many companies that provide door supervisors in London who are able to provide fully trained individuals who are knowledgeable in access control procedures. The best way to keep your building crime free is to keep unwanted characters outside. Unfortunately that does not necessarily help if the criminals are already inside.
True security is every ones concern
Far too many residents of buildings become complacent and overly lax when they know there is a door supervisor at the entrance. They never stop to consider that one person could never cover all of the bases especially in a very large building. Security just like baseball is a team sport which requires a concerted effort from all residents in a specific building. At the very least there should be a security committee represented by some residents that should support the door supervisor or more security personnel should be hired to ensure a higher level of security. One of the first steps will always be to contact a company that provides door supervisors in London but in a large building additional measures has to be taken.
Never rely entirely on the door supervisor
Even highly trained military personnel make mistakes and no matter how much training your door supervisor may have they are human and as such are prone to make the occasional mistake. Therefore there has to be vigilant residents who keep an eye on the door supervisor and at the same time on the rest of the building in order to ensure that all possible risks are properly identified and steps have been taken to contain such risks. Most security companies who provide door supervisors in London have security specialist who could help you to evaluate the security in your building and who could advice you on the proper measures to implement in order to make the building even more secure.
