§ 04Why choose this
Built for the way you actually use it
6MP Resolution with 120dB Wide Dynamic Range
Captures exceptional detail from bright Australian sunlight to deep shadows, enabling facial recognition at 8-10 metres and clear number plate identification.
IP67 and IK10 Protection for Harsh Conditions
Completely dust-tight and submersion-resistant weatherproofing with highest-grade vandal resistance withstands Australian heat, tropical humidity, dust storms, and bushfire ash.
Built-in Audio with Alarm Integration
Omnidirectional microphone captures sound up to 5 metres, with audio and alarm input/output interfaces enabling integration with security systems for comprehensive protection.
§ 05Where it fits
Right at home in these scenarios
Retail Shop Floors and Checkout Areas
Monitor customer interactions and transactions with searchable human detection that saves hours reviewing incidents, whilst audio recording provides dispute resolution evidence.
Office Reception and Car Park Monitoring
Wide 105-degree coverage from ceiling-mounted 2.8mm lens captures visitor entries, vehicle movements, and perimeter access with 24/7 infrared night vision capability.
Front Verandah and Driveway Surveillance
Side-mounted 4mm lens provides focused 84-degree view of approaching visitors, delivery personnel, and vehicle number plates with built-in microphone recording interactions.
Warehouse and Loading Dock Security
Weatherproof construction withstands outdoor Australian conditions whilst AcuSense alerts staff to genuine human presence rather than false triggers from moving objects.

Installation Requirements
1. Power Source: Requires PoE switch or PoE injector (IEEE 802.3af Class 3, maximum 7.5W) as NBN routers lack PoE capability, or 12 VDC power supply 2. Network Connection: Cat5e or Cat6 outdoor-rated Ethernet cable running from PoE switch to camera location, with weatherproof junction box recommended for cable connections 3. Mounting Surface: Solid wall or ceiling surface capable of supporting 550g camera weight, with silicone sealant required for weatherproofing wall penetrations in outdoor installations
App Setup
1. Download Hik-Connect app from Google Play Store or Apple App Store, then register account using email address and select Australia as region during registration 2. Enable Hik-Connect service via camera web interface under Configuration → Network → Platform Access, then verify email with security code 3. Add camera by scanning QR code or manual verification code entry for remote viewing over WiFi, 3G, 4G, or LTE networks with 128-bit SSL encryption
§ 07Questions
Frequently asked
Q.01
What's the difference between the DS-2CD2166G2-I and the DS-2CD2166G2-ISU?
The "-ISU" variant includes a built-in microphone, audio input/output, and alarm I/O terminals. The base "-I" model has none of these — it records video only. Choose the ISU if you want audio monitoring or want to connect external sensors or sirens.
Q.02
Does this camera support PoE, or do I need a separate power supply?
Yes, it supports PoE (IEEE 802.3af, Class 3) so a single Ethernet cable handles both power and data — no separate power adapter needed. If PoE isn't available, it also accepts 12V DC via a coaxial plug, though PoE is strongly recommended for cleaner installs.
Q.03
Which lens size should I choose — 2.8mm or 4mm?
The 2.8mm gives a wide 105° horizontal view, ideal for covering large open areas like driveways or carparks. The 4mm offers a narrower 78° view with better reach, better suited for corridors, entrances, or targeted monitoring where detail at distance matters more.
Q.04
Will this camera work with my existing Hikvision NVR?
It is compatible with Hikvision NVRs that support ONVIF (Profile S/G/T) or ISAPI. However, to get full AcuSense smart event features (human/vehicle classification alarms), your NVR firmware must be up to date — older firmware may only support basic motion detection. Check Hikvision AU's firmware page before connecting.
Q.05
Can I record directly to a microSD card without an NVR?
Yes, the camera has an onboard microSD/SDXC slot supporting cards up to 512GB. This allows standalone recording triggered by motion events. Many Australian users use this as a backup when the NVR is temporarily unavailable (ANR — Auto Network Replenishment).
Q.06
How well does this camera perform at night?
The built-in IR illuminator reaches up to 30m, and the DarkFighter sensor captures colour images down to 0.003 lux before switching to black-and-white. It won't stay in colour as deep into the dark as ColourVu models, but low-light performance is significantly better than standard IP cameras.
Q.07
Does AcuSense actually reduce false alarms from pets or trees?
Yes — this is one of the most practical benefits for Australian residential users. The deep learning engine filters out triggers from animals, blowing foliage, and insects, only alerting on confirmed humans or vehicles. Expect a significant drop in nuisance notifications compared to standard motion detection cameras.
Q.08
Is this camera suitable for outdoor use in harsh Australian conditions?
Yes. It carries IP67 weatherproofing (dust-tight and protected against water jets) and IK10 vandal resistance (impact-rated). It operates in temperatures from -30°C to 60°C, making it suitable for rooftop or exposed outdoor installs across most Australian climates. Note it has no specific anti-corrosion protection, so it's not recommended for direct coastal or marine environments.
