• Hybrid illuminationwith IR and white light up to 40 m plus an active strobe/siren and built-in speaker for deterrence.
• Deep-learning analyticsincluding human/vehicle classification, perimeter protection (line crossing, intrusion), and face capture to reduce false alarms and increase operational value.
• Rugged outdoor buildwith IP66 and IK10 ratings, suitable for exposed locations and vandal-prone installations.

Detailed specifications and benefits

To appreciate what this camera offers, it helps to break down the principal subsystems and their real-world advantages.

• Image sensor: 1/1.8" progressive scan CMOS. Benefit: good light sensitivity and cleaner motion handling at 4 MP resolution.
• Max resolution: 2688 1520 (4 MP). Benefit: higher pixel density for clearer details compared with 2 MP/1080p units.
• WDR 130 dB and shutter range to 1/100,000 s. Benefit: improved clarity in scenes with mixed lighting (backlight or glare) and reduced motion blur.
• Video codecs: H.265 / H.264 / MJPEG and frame rates up to 25/30 fps. Benefit: efficient bandwidth and storage management while preserving smooth video.

• Motorised varifocal 2.8 69 mm (F1.2) with horizontal FOV ~114.6 41.8 . Benefit: remote zoom and re-framing let installers and operators adjust coverage without physical access to the camera, saving time and enabling quick response.
• Depth of field ~1 m to infinity. Benefit: good coverage for perimeter and street-level monitoring where subjects may be at varying distances.

• Smart hybrid illumination (IR + white light) with up to 40 m range and 850 nm IR. Benefit: retains colour at very low lux levels using ColorVu and provides high-quality monochrome or colour images when required. White light supports colour capture and acts as a visible deterrent; IR extends covert monitoring range.
• Built-in speaker, siren, strobe and dual-array microphone. Benefit: enables two-way voice, pre-recorded warnings, and audible/visible deterrence that can stop intruders before incidents escalate.

• Deep-learning analytics: human/vehicle classification, perimeter functions, face capture. Benefit: fewer false alarms and more actionable alerts for security teams.
• ONVIF support, standard network protocols and microSD/NAS storage options. Benefit: flexible integration into existing VMS/NVR environments and redundancy options such as ANR for network interruptions.
• Power: 12 VDC or PoE (802.3at). Benefit: simplifies deployment in modern installations using PoE switches and supports higher power draw when strobe/illumination is active.

Use cases and scenarios where this camera excels

This camera is tailored for environments that require both identification and deterrence. Representative applications include:

• Perimeter protection for commercial sites:Manufacturing plants, logistics yards and retail properties benefit from the camera's long-range colour imaging and active deterrence. The deep-learning perimeter analytics reduce nuisance alarms from foliage or animals while correctly flagging people and vehicles.
• High-end residential estates and gated communities:For homeowners and estate managers who want evidence-grade colour footage at night, the ColorVu capability helps identify vehicle colours, clothing and other details that IR-only cameras can obscure.
• Parking lots and vehicle access control:Motorised framing and human/vehicle classification make it easier to monitor lanes, entrances and stalls while reducing false events caused by motion from non-vehicles.
• Critical infrastructure and transport hubs:Stations, depots and utilities require rugged hardware (IP66/IK10) and analytics to prioritise events quickly; the camera’s hybrid illumination and active deterrence add operational flexibility.
• Retail and hospitality external surveillance:The combination of 24/7 colour, audio warnings and remote zoom helps loss prevention and incident response without bringing security personnel on-site immediately.

Comparisons with similar products on the market

When choosing a surveillance camera, buyers commonly weigh ColorVu-type solutions against traditional IR-only cameras, PTZs, and competing Lightfinder/Starlight offerings. Key points of comparison:

• ColorVu vs IR-only cameras:Traditional IR switches to monochrome images at night and may hide colour cues. ColorVu uses a larger aperture and white-light capability to retain colour in low light, improving identification. Where colour is essential for evidence, ColorVu-style cameras typically outperform IR-only models.
• Motorised PTRZ dome vs fixed varifocal domes:Motorised PTRZ allows remote zoom and re-framing, which saves site visits and enables rapid response to evolving situations. Fixed lenses demand physical access or compromise on coverage.
• Active deterrence vs passive recording:Adding a speaker, siren and strobe provides proactive loss prevention. Competitors offer similar deterrence packages, but integration quality (volume, strobe timing, triggered messages) and analytics determine effectiveness.
• Compared to premium low-light technologies (e.g., Axis Lightfinder, Dahua Starlight):Each vendor uses different sensor tuning and software to improve low-light imagery. ColorVu emphasizes full-colour nighttime imaging using white light and lens/aperture choices. Buyers should compare sample footage in target lighting conditions, evaluate analytics accuracy and consider ecosystem compatibility (ONVIF, VMS support) when choosing between brands.

Customer feedback and testimonials (representative)

No official customer testimonials were provided with the product brief. Below are representative, anonymised examples based on common installer and end-user feedback for similar ColorVu motorised dome cameras:

• "We upgraded perimeter cameras at a logistics site and immediately saw better identification of vehicle colours at night. The active speaker has reduced after-hours trespass incidents."
• "Motorised zoom saved us two site visits during commissioning. We could adjust framing remotely and lock down coverage without scaffolding."
• "Analytics have cut down false alarms; we now get more meaningful events forwarded to our control centre rather than noise from trees and shadows."

Conclusion: Why this camera is a strong choice

The DS-2CD2747G2H-LIPTRZS2U/SL 4 MP Motorised PTRZ ColorVu Dome Camera is a balanced choice for projects where continuous colour detail, remote flexibility and active deterrence are priorities. Its 4 MP sensor and motorised 2.8 69 mm lens support clear identification across a wide scene, while hybrid illumination and built-in audio/strobe enable both covert recording and visible deterrence when needed. Deep-learning analytics reduce false alerts and focus operator attention, and rugged IP66/IK10 construction means the camera can be trusted in exposed, high-risk locations.

For integrators and security managers, the camera’s PoE support, ONVIF compatibility and multi-storage options make it straightforward to deploy into existing systems. If your use case demands 24/7 colour evidence, remote adjustability and proactive deterrence, this unit is worth evaluating alongside competing low-light solutions—review sample footage, verify compatibility with your VMS/NVR and confirm local compliance markings before purchase.
