Home CCTV

Tips to remember when choosing a home cctv.

Look at the size of your house in order to figure out how to choose the right home cctv installation. You will want to have full coverage or as near to full coverage as possible. This means you may need to add additional cameras. You may need to get additional dvr’s in order to capture all of the video feeds. Knowing how many video feeds you will need to monitor will make it easier to choose the right dvr. Also make sure the recorder will work with your current PC.

Remote access to your cctv setup can be a great benefit. Being able to monitor the feed when you are not there on a pc can be an excellent feature.

Capturing audio is not essential and is not all that helpful. Unless you have other reasons for audio capture you can leave this feature off the list.

It is important that you shop around and talk to different retailers. This is a good idea whether you are planning on having a professional installation or you will do it yourself. Choose the dealer you are most comfortable working with and one who is willing to answer any questions you may have.

CCTV for shops

Wednesday, July 20th, 2011

Closed-circuit television, or CCTV for short, is used by transmitting a signal to a specific place on several different screening monitors through the use of video cameras. CCTV is slightly different from broadcast television in the sense that the signal used is not transmitted openly and may vary through point to multipoint, point to point, or mesh wireless links available.

Although most video cameras are able to support this definition, CCTV is typically used for surveillance in areas such as casinos, banks, mini-marts, casinos, as well as stores and shops of all kinds. For instances when closed-circuit television is used for the important tool of distance education, it is often referred to as Videotelephony. Investing in CCTV for shops equipment for your shop will provide you with long lasting benefits to help ensure success for your business. Recent studies have shown a crime decrease of fifty-four percent when CCTV cameras are installed for the use of surveillance in both stores and parking lots alike, where they are most helpful and often used.

CCTV will prevent cases of shoplifting from happening and can also provide safety for both shoppers and employees. A recent estimate from the CCTV User Group shows that approximately 1.5 million CCTV for shops cameras are installed in major retail locations, and the number is vastly growing.

A one time investment for CCTV surveillance cameras will provide unlimited benefits for your shop, and in turn will help run a successful long-lasting business.

Positioning CCTV

Wednesday, July 13th, 2011

CCTV engineers are more than guys (or ladies) who turn up and wire up a couple of cameras and hook them into a logger. They are also there to give you advice on where they should go. CCTV experts are also security experts – they know about vulnerable areas and the thought-set of criminals hoping to avoid being detected.

CCTV engineers will help you position a network of cameras and sensors around your premises to make sure there are no easy escape routes, unguarded depot areas, or vulnerable employees. They can advise you on whether your security strategy should include multiple cameras, or fewer cameras with fish-eye lenses. You may be able to cover the corner of a warehouse with one CCTV camera doing an automated sweep. However, the engineers may also advise you to have a manual operated camera controlled by a security officer in your main office.

As you can start to see, CCTV is a simple concept, but with a vast range of security strategies that need to be examined. There is no single solution that fits all circumstances. The best CCTV system for you will be tuned to your needs and your vulnerabilities. So, before you buy that glorified web-cam from that catalogue store, think to yourself if it is really what you need.

You may also be wise to check with your insurer about whether the system you have is sufficient to meet the requirements of your insurance policy. You may save several thousand by fitting a cheap CCTV system – but would you actually be saving in the long run if something happened on site and then you discovered that you were not covered for any losses?

Maintaining CCTV

Wednesday, July 6th, 2011

Fitting CCTV is a great deterrent to criminals. It not only improves the chances that they will be caught on camera and identified, but it also limits the range of opportunities they have to commit crime. This is because there are more places than ever across the country covered by a monitoring system.

However, if you are in charge of such a system, and have spent a good deal of money on procuring a CCTV network to protect premises, then you should make sure you have a contract which includes regular maintenance and upgrades. What would be the point of having a camera system if it was not focussing accurately and caught a crime in the act – only it was all out of focus and nobody was identifiable!

Another reason for regular servicing of CCTV systems is to make sure the computer software and hardware is all working properly. Modern systems work by recording on a hard disk logger – just like a standard computer network server. If that hard disk develops an error, or becomes full to capacity with data, then your CCTV system will not be storing the images you may need in the event of a breach of security.

Then there is the more basic level of servicing CCTV systems – simply going out and cleaning the lenses. Cameras can end up very dirty because of pollution and even bird droppings. They should be cleaned on regular occasions to make sure there is nothing obscuring the clarity of the image being stored for future use.

Insurers and CCTV

To explain to you the importance of checking whether your security system complies with your insurance policy, it would be useful to relate this to home security. Many insurers will refuse to pay up on a policy if you have a break in, and it is later discovered that you had not got proper locks on the doors and windows. Some home insurers will refuse to pay out after a crime if there isn’t an alarm, or it is discovered that an existing alarm had not been set.

Now look at the security system you have fitted on your commercial premises. Have  you got a good enough CCTV network to fulfil the requirements of your insurance policy? It is not enough for you to just stand outside the front of your factory unit and say: “that will do!” It is advisable to have a professional security expert, who has been approved by the insurer, to carry out an audit of your premises.

The audit will look at every thing from locks and alarms, to smoke detectors and CCTV cameras. The auditor will check to see that there are no unguarded or unsecured exits. The auditor will also make sure that any existing camera network has a clear view of doors and windows that could be used by criminals.

CCTV is also useful inside work areas for health and safety. If an employee were to suffer an accident on the premises, a clear recording of what happened could be used as evidence in any ensuing court case or tribunal.
