Introduction to the DS-2CD2643G2-IZS and its key features
DS-2CD2643G2-IZS — 4 MP AcuSense outdoor bullet camera with motorised varifocal lens.This camera combines a 4 MP sensor, motorised 2.8–12 mm varifocal lens, AcuSense deep-learning analytics and robust outdoor protection to deliver a versatile, identification-grade solution for perimeter, parking and entrance monitoring. Designed for professional installations, the unit supports PoE (802.3at), on-board storage, H.265 compression and smart IR up to roughly 60 meters, all housed in an IP67 / IK10-rated body.
- 4 MP resolution for clearer identification and more usable evidence.
- Motorised 2.8–12 mm lens (F1.6) for flexible field of view (95.86 629.2).
- AcuSense analytics to reduce false alarms by classifying humans and vehicles.
- Smart infrared illumination (850 nm) to around 60 m; advanced low-light features including 120 dB WDR and 3D DNR.
- PoE or 12 VDC powering plus microSD and NAS support for flexible recording options.
Detailed specifications and benefits
The DS-2CD2643G2-IZS uses a 1/3" progressive-scan CMOS sensor and delivers a maximum resolution of 2688 D7 1520 (4 MP) at up to 25/30 fps. That resolution provides a tangible step-up over 2 MP devices for license-plate and facial detail at moderate distances, while still keeping bandwidth and storage manageable with modern compression.
The motorised varifocal lens (2.8D112 mm) with F1.6 lets installers zoom in or out remotely during commissioning to frame scenes precisely. Horizontal field of view ranges from roughly 95.86 (wide) to 29.26 (tele), meaning a single camera can cover wide entrances or be narrowed to focus on gates, doors or lanes.
Low-light capability is a standout: the camera lists a minimum illumination of 0.005 lux in colour mode (F1.6) and 0 lux with IR. It uses 850 nm IR diodes with smart illumination up to ~60 m for reliable night coverage. Features such as 120 dB Wide Dynamic Range (WDR), 3D Digital Noise Reduction (DNR) and BLC/HLC help retain usable details when scenes include bright highlights and deep shadows.
AcuSense deep-learning analytics provides human and vehicle classification to reduce nuisance alarms triggered by animals, weather or small moving objects. Supported smart events include line crossing, intrusion, face detection and tamper alarm. For busy sites where false positives create alert fatigue, this classification can significantly improve response effectiveness and reduce time spent reviewing footage.
The camera supports modern codecs (H.265 / H.265+ / H.264) and multiple streams with ROI and SVC support. Efficient compression reduces network and storage costs without sacrificing critical detail. Storage options include on-board microSD (up to 512 GB) and NAS via NFS/SMB, plus standard network protocols (ONVIF Profile S/G, RTSP, HTTPS) for integration with third-party VMS platforms.
Power options include PoE 802.3at (Class 4) or 12 VDC, with typical maximum draw around 13 15 W on PoE. The bullet form factor measures roughly 308.5 D7 97.9 D7 93 mm and weighs about 1.39 kg. It is built to withstand harsh conditions (IP67 ingress protection and IK10 impact resistance) and operate across a wide temperature range (-30 C to 60 C), making it suitable for exposed outdoor mounting.
Installers should configure analytics zones and IR levels during commissioning for best results. Power should be isolated before installation and local regulatory standards (CE/UKCA or regional) should be confirmed in the official datasheet. Warranty and certification details vary by supplier; confirm these with the vendor before purchase.
Use cases and scenarios where this camera excels
The DS-2CD2643G2-IZS is well suited to a broad range of surveillance needs where clear identification, reliable night coverage and reduced false alarms are priorities.
- Perimeter security:Wide to narrow motorised zoom makes it easy to cover fences, gates and external boundaries. AcuSense analytics reduces nuisance triggers from foliage or small animals, focusing alerts on people and vehicles.
- Car parks and driveways:IR to ~60 m and 4 MP detail capture registration plates and driver actions across multiple lanes. The camera can be angled to capture entry lanes or broader parking bays.
- Commercial entrances and loading docks:Face detection and high-resolution imagery help identify individuals and record interactions at doors, loading bays and reception areas.
- Retail and loss prevention (exterior):Use the camera to monitor store fronts, delivery zones and customer pick-up areas; AcuSense lowers false positives from weather or small animals so staff respond faster to real incidents.
- Residential and multi-dwelling units:For apartment complexes and gated communities the camera provides a robust, vandal-resistant option for perimeter and access control monitoring.
- Construction sites and temporary installations:Rugged housing, PoE powering and flexible recording make it practical for semi-permanent monitoring where weather and impact resistance matter.
Comparisons with similar products in the market
When evaluating the DS-2CD2643G2-IZS, it helps to compare by feature category rather than model name. Key differentiators include the motorised varifocal lens, AcuSense analytics and IR range.
- Motorised varifocal vs fixed lens cameras:Fixed-lens cameras are typically cheaper but less flexible at installation. A motorised 2.8D112 mm lens lets installers remotely adjust framing without re-mounting, saving time and providing future flexibility if site needs change.
- AcuSense analytics vs basic motion detection:Traditional motion detection triggers on any pixel change and generates many false alarms. Deep-learning classification (human/vehicle) such as AcuSense markedly reduces false positives and improves the signal-to-noise ratio for security teams.
- 4 MP vs 2 MP cameras:4 MP provides better detail for identification and license plates at moderate distances. While higher resolutions like 8 MP are available, 4 MP often balances image detail with bandwidth and storage savings when using H.265+ compression.
- Bullet vs dome vs PTZ:Bullet cameras like this are visible deterrents and are easy to point at specific targets. Dome cameras can be more discreet and resistant to tampering in some sites, while PTZs offer active tracking and wide-area coverage but at higher cost and complexity.
Customer feedback and installer observations
Direct customer testimonials for this exact model vary by region and installer. Common themes reported by installers and end-users include:
- "AcuSense dramatically reduced nuisance alarms compared with older models — fewer animal and weather triggers."
- "The motorised lens saved us time on commissioning; framing was quick and accurate without re-climbing ladders."
- "Night-time performance is reliable across car parks; IR reach and smart illumination avoid washed-out close objects."
- "PoE powering simplifies installation and the option for microSD backup gives redundancy without extra hardware."
While not universal, some buyers note that configuration of analytics zones and sensitivity takes careful tuning to match site conditions. As with any advanced camera, a qualified installer who understands the analytics and exposure controls will extract the best results.
Conclusion: Why the DS-2CD2643G2-IZS is a strong choice
The DS-2CD2643G2-IZS strikes a practical balance between image quality, smart analytics and rugged outdoor suitability. Its 4 MP sensor delivers identification-capable imagery while the motorised 2.8D112 mm varifocal lens provides installation flexibility that reduces commissioning time and future-proofs field of view requirements. AcuSense classification reduces false alarms and makes monitoring teams more effective, and the cameras efficient H.265+ support helps control storage and bandwidth costs.
For commercial and residential perimeter surveillance, parking areas, entrances and other outdoor scenarios where reliable night coverage and reduced nuisance alerts matter, this model is a compelling option. Suggested retail price is 219.00 (confirm local currency and supplier pricing), with a cost base that reflects its professional feature set (cost price reference 162.91). Warranty and certification details are vendor dependent, so confirm compliance and service terms with your supplier prior to purchase.
In short, if you need a robust, flexible outdoor camera that prioritises usable evidence, sensible bandwidth use and fewer false alarms, the DS-2CD2643G2-IZS deserves strong consideration in your next surveillance project.
