Detailed specifications and benefits
This section walks through the cameras capabilities and what those specifications mean in practical terms.
- Image sensor:1/2.7" progressive-scan CMOS delivering up to 2 MP resolution (2560 × 1440) at 25/30 fps. The higher resolution helps with clearer scene context and more reliable analytics.
- Low-light performance:Colour sensitivity down to 0.0176 Lux (F2.25, AGC on) and 0.0035 Lux in B/W, plus IR illumination to approximately 6 m. That enables reliable counts through dawn/dusk conditions and in low indoor light.
- WDR & noise reduction:True 120 dB WDR and 3D DNR ensure balanced exposure across bright entrances and darker interiors while reducing motion noise — important for both human readability and algorithm accuracy.
- Fixed 2.0 mm lens (M12):Provides a wide 104.5 horizontal field of view ideal for doorway and vestibule coverage without the complexity of remote zooming.
- Aperture:F2.25 strikes a balance between depth of field and light gathering for indoor use.
- Day/Night & IR:An IR cut filter for day/night switching and 850 nm IR allows operation in near-darkness up to ~6 m.
- Compression:H.265+/H.265/H.264+/H.264 with a substream option in MJPEG. H.265+ reduces bandwidth and storage requirements while retaining image quality.
- Multi-stream & ROI:Multiple streams and 4 fixed ROI regions enable optimized recording and streaming (e.g., high quality in counting zones, lower quality elsewhere).
- Audio:Built-in microphone (audio codec/options vary by variant), useful for contextual monitoring where permitted.
- On-board storage:eMMC up to 8 GB for local people-count data buffering and scheduled uploads; helpful where network outages occur or local buffering is preferred.
- People-count analytics:Dual-lens stereo counting delivers separate enter/exit counts, with height filtering to reduce false counts from strollers or carts. Scheduled statistic uploads let sites integrate counts into business intelligence systems on a timetable that suits operations.
- Network:10/100 Mbps Ethernet with PoE (802.3af) for single-cable power and data. Protocols include ONVIF Profile S & G, IPv6, TLS 1.3 and common streaming protocols (RTSP/HTTP/HTTPS).
- Power:12 VDC or PoE; typical consumption ~7 W, maximum ~8.5 W, keeping operational costs low.
- Size & weight:Compact physical footprint (~168 × 61 × 36 mm, ~340 g), making it easy to mount above entrances or in ceiling fixtures.
- Environment & approvals:Rated for −30 °C to 60 °C and up to 95% non-condensing humidity; certifications include FCC, CE, UL and CB and RoHS compliance.
Practical benefits
Taken together, the DS-2CD6825G0/C-ISs specs make it a strong fit for organizations that need accurate, repeatable people counts without heavy infrastructure. The stereo-lens approach improves counting accuracy over single-lens methods by providing depth information, while embedded analytics and local buffering reduce reliance on continuous external compute or cloud processing. PoE simplifies installation and lowers cabling costs, and efficient codecs reduce ongoing bandwidth/storage costs.
Use cases and scenarios where this camera excels
People-counting capabilities are valuable across retail, transportation and venue management. The DS-2CD6825G0/C-IS is particularly well suited to:
- Retail doorways and shopfronts:Accurate enter/exit counts help measure conversion rates, staff planning and peak periods. Height filtering reduces false triggers caused by carts or wheeled displays.
- Malls and shopping centres:Mounted at anchor or corridor entrances, the camera can supply aggregated footfall figures for property managers and retailers.
- Event venues and theaters:Monitoring auditorium or gate throughput for capacity planning and crowd control.
- Public buildings and transport hubs:Monitoring flows through turnstiles, concourses or security checkpoints where unobtrusive doorway coverage is needed.
- Temporary or distributed deployments:Lightweight PoE installation and on-board buffering make the camera suitable for pop-up stores or locations with intermittent network connectivity.
Comparisons with similar products on the market
When assessing people-count solutions, buyers commonly compare stereo (dual-lens) counting cameras like this Hikvision model to single-lens cameras with analytics, ceiling-mounted stereoscopic sensors, thermal counters and turnstile/wearable systems. Key comparative points:
- Stereo vs single-lens:Stereo cameras use two sensors to infer depth, which typically improves accuracy in crowded or overlapping scenes compared with single-lens, 2D motion-based analytics that can suffer from occlusion or perspective errors.
- Ceiling-mounted stereoscopic sensors:Dedicated stereo sensors mounted directly overhead can offer slightly higher consistency, but often require different mounting hardware and a narrower focus on counting. The DS-2CD6825G0/C-IS provides a balance of imaging and analytics with added video context for security or situational awareness.
- Thermal and non-optical counters:Thermal counters can be privacy-friendly and effective in low light but may provide less scene context. Optical stereo cameras add visual context that can be useful for troubleshooting counts or integrating video-based analytics.
- Cloud analytics services:Cloud-based counting can offer centralised analytics and aggregated insights, but depend on consistent bandwidth and may have higher ongoing costs. On-device counting with scheduled uploads (as in this Hikvision camera) reduces bandwidth needs and offers resilience to connectivity interruptions.
Overall, the DS-2CD6825G0/C-IS occupies a middle ground: more accurate than purely 2D single-lens solutions for many doorway scenarios, yet more flexible and informative than dedicated non-visual counters.
Customer feedback and real-world impressions
While specific buyer testimonials for this exact model may vary by deployment, installers and operations teams who work with stereo people-counting cameras commonly report the following practical strengths:
- Improved counting accuracy:Stereo depth information reduces false positives from trolleys and clutter in doorway flows.
- Simplified deployment with PoE:Reduced cabling and faster installation time when powering the camera via PoE.
- Resilience to network interruptions:On-board eMMC buffering helps preserve count data until scheduled uploads are possible.
- Good value for combined video and counting:Buyers appreciate the option to use the device for both analytics and contextual video when privacy rules permit.
Note:If you require direct user reviews or performance benchmarks for your exact installation scenario, request reference deployments from your supplier or arrange a pilot to validate accuracy under your specific doorway geometry and traffic patterns.
