• WDR / SNR:WDR 130 dB and SNR a0
  
  
  8 dB. Benefit: balanced exposure across high-contrast scenes (backlit entries, bright skies and dark foregrounds).

• Motorised 2.8a0a0aa
  
  4 mm varifocal (F1.6):allows remote adjustment of angle of view during commissioning. Benefit: rapid on-site framing and focus without physical lens swaps or ladder climbs.
• Field of view (H):2.8 mm = 99.3
  
  
  
  ; 4 mm = 80.0
  . Benefit: flexible coverage options from wide-area overview to tighter identification fields.
• IR range:Up to 60 m (850 nm, Smart IR). Benefit: reliable night-time illumination for extended perimeters while avoiding IR overexposure on near objects.

• Codecs & streams:H.265/H.264 and enhanced H.265+/H.264+; supports main, sub and third streams. Benefit: improved bandwidth and storage efficiency without compromising main-stream quality.
• On-board & network storage:microSD up to 512 GB, NAS (NFS/SMB), ANR supported. Benefit: resilience in network outages and local buffer recording for continuous coverage.
• Image enhancements:BLC, HLC, 3D DNR. Benefit: better image clarity in challenging lighting, reduced noise at slow shutter speeds.

• AcuSense person/vehicle classification:deep-learning based filtering to reduce false alarms from foliage, animals and lighting changes. Benefit: fewer nuisance alerts and more accurate intrusion notifications.
• Perimeter protection & face capture:configurable tripwire, intrusion rules and snapshot capture. Benefit: targeted alerts and evidence capture for security teams.
• Audio:Built-in dual microphones and a speaker (approx. 2 W) supporting G.711, G.722.1, G.726, MP3 and AAC-LC. Benefit: two-way audio for deterrence, access control announcements and incident verification; combined with strobe/alarm linkage on SL variants enhances deterrence.

• Power:12 V DC or PoE IEEE 802.3at (Class 4), maximum ~18 W. Benefit: flexible deployment options; PoE simplifies cabling and centralises power management.
• Operating range:-30a0
  
  
  
  
  
  C to 60a0
  
  
  
  
  
  C with up to 95% non-condensing humidity. Benefit: reliable operation in harsh climates.
• Ingress protection:IP67 and anti-corrosion construction. Benefit: long-term outdoor reliability in rain, dust and coastal environments.

Use cases and scenarios where this camera excels

The DS-2CD2T46G3-IZS2UY/SL is a versatile outdoor bullet camera suited to a variety of scenarios where identification, low-light performance and actionable alerts are priorities.

• Large perimeters (warehouses, campuses, industrial sites): motorised varifocal lens makes framing long fences or gates straightforward; 60 m IR preserves overnight visibility.
• Deterrence-sensitive sites: strobe/siren and two-way audio on SL/RB variants provide active deterrent capabilities in response to detected intrusions.

• Car parks and storefront façades: AcuSense reduces false alarms from environmental triggers, while 4 MP resolution helps with registration plate and face capture at moderate distances.

• Small sites and high-value homes: PoE deployment simplifies cabling and integration with NVRs; DarkFighter maintains useful colour information in low light without always relying on IR.

Comparisons with similar products on the market

When evaluating the DS-2CD2T46G3-IZS2UY/SL, consider how its capabilities compare to other common options:

• Fixed-lens cameras are typically cheaper but lack on-site framing flexibility. The motorised varifocal lens of the Hikvision unit reduces commissioning time and future-proofs changes to scene requirements.

• 2 MP cameras use less bandwidth and storage, but the 4 MP image delivers more detail for identification at medium distances. With efficient H.265+ compression, the storage penalty is reduced.

• AcuSense provides robust person/vehicle filtering similar to competing AI offerings. Differences to evaluate include the quality of false-alarm suppression, integration with NVRs and the presence of active deterrence features (strobe/siren/audio), which this Hikvision model includes on certain variants.

• Compared to dome cameras, bullet cameras like this Hikvision unit are easier to aim from ground-level mounts and offer visible deterrence presence, though domes are often preferred for aesthetics and vandal resistance in some environments.

Customer feedback and typical reviews

There are no individual customer testimonials provided here, but common themes reported by installers and end users for cameras in this category include:

• Positive feedback on image clarity and low-light colour performance thanks to DarkFighter, particularly in urban and suburban exterior settings.
• Appreciation for the motorised varifocal lens: installers save time and can fine-tune scenes remotely from an NVR or client software.
• High marks for AcuSenses ability to filter out non-relevant triggers (animals, shadows), reducing time spent reviewing false alarms.
• Notes about power requirements: installers highlight the need for PoE+ (802.3at) if powered via Ethernet, and recommend checking switch/injector capacity to avoid brownouts.
• Some users call out the lack of included warranty in certain sales channels; buyers should confirm warranty and support terms with their reseller.
