Following are the issues you need to address before buying a CCTV system:
Should my CCTV cameras be discreet or a visual deterrent?
Box cameras present an obvious sign for anyone who passes by that they are being recorded on CCTV and this can be a great deterrent of theft and crime. Whereas dome cameras are smaller and more discreet. These compact cameras are ideal for monitoring a larger area such as your front or back garden and can follow movement with ease.
How do I know what to use indoors and outdoors?
When thinking where you would like to place your cameras, you might want to think about how they will be mounted and housed, in order to ensure that they’re in the best location and well protected. For example, if your camera is to be placed outside, you will want it to be robust and weather proofed. If it’s to be placed indoors you will want to ensure it will not be affected by grease or steam from a kitchen.
What are the light conditions like?
Test different camera models to see what works best with the lightning in your area, because no matter whether they’re inside or outside, the lighting will differ throughout the day. You will want to check any reflections and back lighting during the day and night.
Is image clarity important?
Depending on how expansive the area is that you want to cover, the resolution of the CCTV camera you choose will need to reflect the landscape in order to provide a clear, useful image. However, if situated in a small room, the camera need not be of a high resolution.
Is audio required?
Audio isn’t required, however, if you do wish to opt for audio there are systems where you can speak to a person who has broken into the property. Audio can be used to deter criminals by automatically playing something when they get a certain point inside, an ideal way to make them think that there are people inside the building.
