Many security cameras do have audio recording functionality, however you will need to check specifically against each model as there are a wide range of solutions that both include and exclude microphones within the camera. Some models also include a speaker that can provide audible alarms and spoken messages upon human or vehicle detection.

This depends on the size, layout, desired coverage and types of cameras used for the project, however as a general rule it is critical to cover all entry and exit areas as a starting point. Additional coverage may be required to surveil specific stock, work areas and external car parks but this will be different for every business. As an example, we can propose a 1,250 sqm (50m x 25m) warehouse with an open view plan. Aiming to observe people in the workplace using a common 6MP camera with a 97 degree horizontal field of view and factoring in four entry/exit points. This scenario would require at least 10 cameras for an even internal coverage. The same size factory with extensive pallet racking and the same aim may however require 30 – 40 cameras to ensure even coverage.

Typically a 6MP dome or turret camera will be sufficient to cover a cash register, however it is important to position the camera in a way that the view cannot be obstructed. In some cases it is best to utilise two cameras from different angles to ensure that the view cannot be obstructed at any time.

A typical CCTV system with 16 cameras will require less than 150 watts of power per hour. This is comparable to a basic desktop computer and less than most larger LCD TVs, however it is important to recognise that the security camera system is usually running 24/7 and will consume power continually

Most commercial grade CCTV systems typically record directly to a dedicated set of surveillance hard drives that are installed into a network video recorder or server. WiFi is not normally required to record any CCTV footage, however some more basic consumer grade systems may use this method for recording.

CCTV systems can be configured to record 24/7 but can also be set to record only when activity is detected. We recommend, where possible to maintain 24/7 recording to avoid any potential footage being missed, this will however utilise the most amount of storage space and may not be possible in all instances. Setting a system to record on motion or human/vehicle detection can be a good way to conserve disk space and record over a longer period of time.
