Frequently Asked Questions
Where should CCTV be used?
Anywhere! Literally - not only as a security measure but can be used to monitor staff protection, staff management, shrinkage and criminal damage.
Please note there are some legislation with regards to Dataprotection Act, click here to read CCTV Code of Practice.
Should I use Overt or Covert?
This is normally a personal issue however overt (visual) cameras are more popular especially as they not only record but act as a deterrent also. Covert (hidden) are used for delicate situations whereby you have ongoing problems that cannot be dealt with during conventional business conduct. Both types of systems are extremely effective.
Should I use Colour or Black and White?
Another personal issue - although there are some guidelines to be adhered to: Colour does not work well in dark conditions unless you have superb lighting or use of Digital Cameras. Infra Red will not work with Colour Cameras. Black and White Cameras are normally a higher specification and offer a far crisper picture. Black and White will work well at night with the aid of Infra Red or normal Halogen Lighting.
Which Lens do I use?
Great question - how long is a piece of string? There is a calculation for this and rather than bore you with algebraic logarithms, please call us.
