What areas are you protecting and what impact would any losses have to your business?<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

When you weigh up the potential loss against the cost of security, logic dictates the requirement for protection of some sort. Commercial property owners will generally have their insurance requirements to consider as your cover may be dependent on having systems in place that meet a certain grade. For most businesses owner\u2019s CCTV is a must.<\/p>

Due to the huge rise in \u2018Off the shelf\u2019 CCTV solutions that have been designed for DIY installations, business owners can sometimes find themselves confused as
to the difference between these types of system and ones offered by professional companies such as BAC.<\/p>

So, the question now is\u2026\u2018Should I choose the DIY options or have a system supplied and installed by a Professional Security company?\u2019 This article should give you the information required to make an informed
decision.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

What is a DIY CCTV system?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A self-install or DIY system is one that can be purchased from places such as Electrical shops or other high street retailers. You can also find these systems online from numerous websites.<\/p>

\"\"These types of CCTV system are often referred to as \u2018plug and play\u2019 meaning that the cameras are pre-configured for use with the recording unit (DVR or NVR). Once cabled you simply plug the cameras into the recording unit and switch it all on. The system will then set itself up, all you have to do is nominate a password.<\/p>

Self-install cameras like the ones shown above can be a lot smaller and tend to have a limited range of lens sizes, nearly all being a fixed lens of 2.8mm. The downside of this lens size is that the areas covered by the camera’s vision will be a general overview disallowing you close up vision of objects. You can of course \u2018blow up\u2019 the images but unless you have a VERY high megapixel camera this will mean losing resolution.<\/p>

This is fine for very simple applications on small sites, however, larger premises would potentially need additional cameras to ensure the system covers the area you need. See the lens size chart for a better visual explanation below.<\/p>

These systems generally have basic security features such as recording images, footage playback and can be set up for remote viewing via your home or businesses broadband.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

What difference does lens size make?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

As you can see by the chart, lens size can make a massive difference in terms of the quality of images when at a distance.<\/p>

If you have something you want to cover which is for arguments sake 100M away, you would not be able to use any images from a 2.8mm lens which you could use for identification.<\/p>

For items not in the immediate vicinity, you will require larger lenses in order to have detailed views which are fit for purpose.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
