Frequently Asked Questions
What is an 8MP Dahua CCTV camera?
An 8MP Dahua IP camera records approximately eight megapixels of image information, commonly associated with 4K-class surveillance resolution. This can provide useful additional detail when camera position, lens selection and lighting conditions support it. Dahua offers 8MP cameras across different housing styles and technology families, so resolution should be considered alongside night performance, smart detection, audio and the actual surveillance location.
Should I choose an 8MP or 6MP Dahua camera?
An 8MP camera records more image pixels and can provide additional detail where fine identification is important, while 6MP can provide strong image quality with generally lower recorder bandwidth and storage requirements. The better choice depends on viewing distance, camera position, scene lighting and the size of the overall CCTV system. For larger multi-camera installations, recorder and storage capacity should also form part of the resolution decision.
Do Dahua 8MP cameras provide colour night vision?
Selected models do. Dahua offers different night-imaging technologies within its 8MP range, including Full-Colour Dual Light and WizColor on suitable cameras, while other models use conventional infrared. Dual Light provides infrared and visible-light options, while WizColor is designed to retain useful colour information using available light in low-light scenes. Choose according to the actual conditions around the property after dark.
Do Dahua 8MP cameras have built-in microphones?
Selected Dahua 8MP cameras include a built-in microphone for recording audio together with the video stream. Other models focus on video surveillance without onboard audio. If recorded sound is important, compare microphone-equipped cameras alongside the required night imaging, smart detection and lens configuration. Two-way communication is a separate capability available on selected cameras, including suitable TiOC models.
Can I get active deterrence on a Dahua 8MP camera?
Yes. Selected Dahua TiOC cameras combine high-resolution surveillance with active-response features such as warning lights, audible alerts and two-way communication. This can be useful around entrances, driveways, shopfronts and other exposed locations where an immediate response may help discourage unwanted activity. If deterrence is the main buying requirement, the dedicated Dahua TiOC range is also worth comparing.
Can I buy a complete Dahua 8MP CCTV kit?
Yes. Complete Dahua 8MP CCTV packages combine multiple cameras with a compatible PoE NVR for a new multi-camera installation. Kits vary by camera count, camera style, night-imaging technology, smart features and storage inclusion. A complete system is useful when starting from scratch, while standalone 8MP cameras are better suited to expanding an existing compatible Dahua recorder.
Will Dahua 8MP IP cameras work with a Dahua NVR?
Supported Dahua 8MP IP cameras can be used with compatible Dahua NVRs for recording and live viewing. When adding several high-resolution cameras, consider available channels, PoE capacity, incoming recording bandwidth and storage as part of the system design. The recorder should also support any intelligent detection, audio or other camera functions that are important to the installation.
Does 8MP always mean better CCTV footage?
Resolution is only one part of image quality. An 8MP camera provides more image pixels, but useful footage also depends on lens choice, camera angle, mounting height, subject distance, lighting and night performance. A well-positioned camera with the right lens and illumination can provide more useful evidence than a higher-resolution camera installed in the wrong position. The complete surveillance requirement should therefore guide the camera choice.
