Frequently Asked Questions
What is Dahua Dual Light?
Dahua Dual Light technology gives supported cameras both infrared and visible white-light illumination for night surveillance. Infrared can provide discreet monitoring after dark, while white light allows the camera to capture useful colour information when visible illumination is active. This provides more flexibility than a camera limited to one night-imaging method and can be useful around entrances, driveways and other important areas.
What camera is used in these 6MP Dual Light kits?
These packages are centred around Dahua 6MP Dual Light surveillance, including the DH-IPC-HDW3667EM-S-IL-ANZ camera in supported configurations, together with a compatible Dahua PoE NVR. Package contents can vary by camera count, housing configuration, recorder and storage, so choose the kit according to the complete system required for the property.
What is the difference between Dahua Dual Light and WizColor?
Dual Light provides both infrared and visible white-light illumination, allowing the camera to change how it monitors a scene after dark. WizColor takes a different approach, using high-sensitivity low-light imaging to retain useful colour information from available light. Dual Light is useful where flexible illumination is important, while WizColor can be a better starting point where low-light colour imaging itself is the main requirement.
What is the difference between Dual Light and Dahua TiOC?
Dual Light describes the camera's night-illumination capability, while TiOC is focused on intelligent surveillance combined with active deterrence and two-way communication. TiOC cameras can provide warning lights, audible alerts and remote talk-down on supported models. If flexible night imaging is your main requirement, Dual Light is a suitable starting point; if actively responding to unwanted activity is important, compare the Dahua TiOC range.
Should I choose turret or bullet cameras?
Turret cameras offer a compact housing that works well under eaves and on walls, while bullet cameras provide a more directional appearance that can suit driveways, boundaries and longer approaches. Both styles can form part of a 6MP Dahua CCTV system, so the choice mainly comes down to mounting position, viewing direction and the appearance you prefer for the property.
How many cameras should I choose?
Start by counting the areas that require their own continuous view. A smaller property may need four cameras for the main entrances and outdoor areas, while larger homes and commercial sites may require six or eight cameras to cover side access, car parks, yards or multiple entrances. Choose camera count according to real coverage requirements and consider spare recorder capacity if the system may grow later.
Is a hard drive included with every Dahua Dual Light kit?
HDD inclusion varies between packages. Some systems may include surveillance storage, while others allow the hard drive to be selected separately according to the recording duration required. Storage capacity should be chosen according to camera count, recording settings and how long footage needs to be retained.
Can I add more cameras later?
Yes, provided the Dahua NVR has spare camera channels, suitable PoE capacity and support for the additional cameras. Adding cameras also increases recording and storage requirements, so HDD capacity should be considered when expanding. Choosing a recorder with suitable spare capacity from the beginning can make future expansion easier.
