UK residents are very hardworking and most people usually work hard to earn a decent living. However, there are also some few people who don’t want to earn their daily bread the honest way. Instead of working hard, they choose to acquire their wealth through stealing or robbing other people items. Fortunately due to advance in technology in UK, many security measures have been put in place to help apprehend law breakers. Covert surveillance systems are optimised military and police surveillance that are usually used to provide high quality link continuity allowing for superior range whilst being contained in a small covert housing. Do to the efficiency of this system many homeowners in the UK are integrating them into their security system. So are you wondering what the benefits of using this surveillance systems ? If yes then below are main benefits.

1. They are efficient.

When compared to other surveillance system, covert surveillance system is very efficient when it comes to fraud detection. When you install this system in your compound you can be sure that no unauthorized person will get in to your compound. It uses the latest technology that enables the user to detect robbers who want to get into your property. In addition to that, this system is durable and when installed they can operate continuously for long period of time. (more…)

While the security door itself is an important part of a security system, the switches that operate them often get overlooked.

It is paramount that a well functioning security door has the correct switch to operate it. There are many different switches and each serves a different purpose, so choosing the right one is crucial.

The majority of switches can be generally defined as manually or automatically operated. Discerning whether a security system needs a manual or automatic switch is usually a matter for an expert.

Automatic switches act when it detects a short upstream of the switch. This means that if the switch detects anything which interferes with the closing of the door, it will disconnect and close.

These can be perfect for security doors as they will function even if there is nobody to manually close the door.

With the breaker system connected to the security infrastructure. An automatic security door becomes an integral and highly functional part of the system.

Many people don’t realise that cleaning a lens is one of the common ways that they are damaged. Cleaning can leaves marks on a lens if not carried out with care and knowledge. This post outlines a straight forward and effective technique that you can use to avoid unnecessary damage.

Using a lens hood, clean the front and rear elements of a lens. A microfiber cloth and ROR fluid can also be used if needed. Kodak also sells lens tissues which work effectively as well.

Knock the big dirt particles off with a camel hair brush, blow off as much as possible, then use a microfiber cloth or lens tissue to remove fingerprints. Aim to use a new segment of the tissue/microfiber with every wipe if possible.

You may also open the back and front elements to get access to the aperture blades and inner elements for simple cleaning. This is only recommended for advanced users as the inner mechanisms can be easily damaged.

Nanchang Changbei Airport, China, a large, rank 4E airport, dealing with large quantities of passangers on a daily basis. Like many large building complexes, the airport has a vast security system designed especially for the airport premises.

The security system consists predominantly of 340 IP surveillance cameras. Positioned in vantage points around the area, the cameras maintain 24/7 visual recordings of the entire complex.

Specific cameras are used for certain areas. For example, SNC-RZ50P and SNC-CS20 network cameras are used in areas with a high footfall of passengers. These cameras have wide angle imaging as well as high depth of field characteristics, perfect for capturing high detail on small, moving objects.

SNC-DS10 and SNC-DS60 cameras, are used forcheck in areas. The progressive scan CCDs and complementary color filters of the cameras are well suited for recording interactions between staff and passengers.

The security system functions effectively, providing users with effective operability and compatibility with existing systems.

A 24/7 recorded feed is great for the fact that you can be sure everything the camera sees is stored. However It can be an issue when sifting through footage to find the specific time the camera actually saw something you should be aware of.

A solution to this is to use motion activated cameras. As the name suggests, these cameras will only start recording when it picks up movement within its visual range.

The advantage to movement activated cameras is that they are usually independent units. So they do not need to be connected to a computer or a power supply. Simply put the camera in a spot you consider a prime place for spotting intruders, and come back to the camera after you suspect it may have picked something up.

The downside to motion cameras is that they are not connected to a direct-feed, meaning they cant be viewed through on demand. This can be an issue for security systems that require real-time surveillance.

There are three main types of night vision. image intensification, active illumination and thermal vision. Most consumer level cameras use IR night vision (Infrared night vision) which is a form of thermal vision and provides adequate light detection at all times of day. There are many other aspects of IR vision to consider such as the variable wave-lengths and actual visibility ranges. These will all need to be taken into consideration when assessing the required task.

For surveillance to provide the best security it needs to be active 24 hours a day 7 days a week. For half that time its dark so it is essential for the best surveillance cameras to have fitted night vision functions. Most modern cameras do have this added function, but it’s important to make sure when selecting cameras to check for the added night vision feature. It is simply not feasible, for today’s security to not have night vision cameras, specifically because it’s common knowledge that most criminal activity is carried out at night time

Protecting a property, making sure it is safe and secure and keeping intruders out. That is the primary goal of security. As long as this goal is met, then a security system passes its most intrinsic function.

With this perspective in mind, it becomes clear that a security system can take many different forms. One of the most effective being the use of nature.

An example of this natural security is the placement of trees, hedges and other large forms of vegetation. This is best considered when constructing the property as the vegetation will need time to grow. But despite this, using trees as a sort of strategic wall, securing a perimeter around a building can be a deceptive form of cover.

It’s no coincidence that foliage has been used like this in the past. Before construction techniques evolved and allowed the creation of perimeter fences, hedges, trees and stone walls were used as defence from intruders.

We all understand security cameras are made predominately for security purposes. Designed to survey the area and provide a visual record. But there are some other uses for security cameras that you may not of realised.

Spotting Wildlife

Cameras are great at spotting animals and birds, their silent operation and accurate lenses lend themselves to the task extremely well.

Astronomy and Stargazing

Cameras can provide a great spot from which to view the stars. The accuracy of the lenses can mean that some cameras are better than spotting stars than the human eye. Cameras are stationary too and because of this their position in relation to the stars allows astronomers to make accurate calculations and assessments.

Long-Term Time-Lapse Photography

A time-lapse photography is a technique that captures many images, over a long period of time and ‘lapses’ them together. This is a method often used by film makers to create a unique and gradual animation-like sequence of images.

Maritime surveillance is a highly technological system designed to give exact findings of an area which lead to faster response chances of threats and behaviors. Surveillance can be carried out by submarines, satellite or aircraft, ships and other sophisticated airborne military vehicles.

The important things that make maritime surveillance a crucial part of any nation are;The system supports the economic development of a country. Most countries with coastlines carry out economic activities. Fishing, tourism and shipping are some of economic activities in the coastlines. The system protects people from fishing beyond stipulated areas and ensures countries hold to set regulations. Surveillance also monitors water transport traffic in controlled waters. Surveillance is mostly carried out by law agencies and military forces. This is because the system gives a security information reports.

The floor plan of a building is an important tool when planning the layout of cameras and security systems. A detailed floor plan will allow the security planners to arrange security cameras in the most efficient manner, with the minimum amount of cameras giving the maximum amount of visual coverage.

Not only does it greatly assist in the arrangement of cameras, but in the installation of  many other security systems. Alarms, laser detection systems and security lights and doors can all be installed in a much more effective manner with a floor plan.

A floor plan gives the planners an aerial overlay of the layout of the rooms, doors, windows and large structural objects in a building. With this overview organising the security systems becomes much easier.

It can also allow the planners to create security choke points, designed to funnel intruders to a certain area. Within these choke points extra security is installed with the aim to detect the intruder.
