Question 1

How many security cameras does a house need?

Accepted Answer

Most homes are well covered by three to six cameras, but the number matters less than the positions. The usual priorities are the front entry, the driveway or street approach, the side access path, and the rear yard or back gate. Corner blocks and properties with two street frontages need more. Start by deciding what you need to be able to see, then place cameras to cover those approaches without duplicating views.

Question 2

Is it better to have more cameras or better placement?

Accepted Answer

Placement, clearly. Four cameras covering four different approaches give you far more useful footage than eight cameras covering the same driveway from several angles. The most common mistake is duplicating a view while leaving the side gate or rear access uncovered. Positions should be worked out first, and equipment chosen to suit those positions rather than the other way around.

Question 3

How high should a security camera be mounted?

Accepted Answer

High enough to be out of easy reach, low enough to capture a face. Cameras mounted very high looking down produce footage that shows the top of a person's head rather than identifiable features. Most homes end up with a mix, including at least one camera positioned specifically to capture faces at a main approach point, with others higher up covering wider areas.

Question 4

Does lighting affect security camera footage?

Accepted Answer

Significantly. A camera facing a bright wall in the afternoon can produce silhouettes, a camera facing a streetlight at night can flare, and a dark side passage relies entirely on infrared which has limited range. This is why camera placement is assessed on site rather than from a floor plan, because the same position performs very differently depending on how light falls on it through the day.

Question 5

Are coastal conditions a problem for security cameras?

Accepted Answer

Yes. Salt air and prolonged sun exposure degrade poorly rated housings quickly, and equipment that performs well inland can corrode within a couple of years near the coast. Cameras and mounting hardware should be specified for the conditions at the property rather than chosen on price alone. It is worth asking any installer what rating the equipment carries and why it suits your location.

Question 6

Do I need a licence to have CCTV installed in NSW?

Accepted Answer

You do not need a licence as a homeowner, but the business installing it does. Installing security equipment for others is licensed work in New South Wales under the Security Industry Act 2003. AVsion holds Security Master Licence 000103421 and Security Operator Licence 000233371. It is reasonable to ask any installer for their licence details before they carry out work at your home.
