Introduction to the TandemVu PTZ + Panoramic Speed Dome
The Hikvision DS-2SE4C425MWG-E/26(F0) TandemVuis a purpose-built outdoor surveillance camera that combines two complementary imaging channels into a single housing: a high-resolution panoramic bullet channel (approx. 6 MP) for wide-area situational awareness, and a 4 MP PTZ channel with 25× optical zoom for detailed, long-range inspection. Marketed as the TandemVu 25× PTZ + ColourVu panoramic, this speed dome is designed for locations that require both continuous overview and the ability to lock on and zoom into incidents—roads, transport hubs, parks, city centres and large car parks.
Key selling points include the dual-channel TandemVu architecture, ColourVu white-light daytime/night-time colour on the panoramic channel, long-range IR on the PTZ channel, deep-learning analytics for human/vehicle classification, and rugged outdoor protection (IP66, wide temperature range and lightning protection). For systems integrators and security managers, the TandemVu promises fewer fixtures, simpler cable runs and more effective event handling than installing separate panoramic and PTZ units.
Detailed specifications and benefits
The TandemVu design merges two camera sensors into one integrated device. The panoramic channel uses a 1/2.5" progressive CMOS sensor delivering roughly 3632 × 1632 resolution (about 6 MP) through a fixed 2.8 mm lens to capture wide scenes. The PTZ channel uses a 1/2.8" progressive CMOS sensor at up to 2560 × 1440 (4 MP) with a 4.8–120 mm motorised lens for 25× optical zoom. Together these channels provide simultaneous streams: a continuous overview for context and a zoomed channel for forensic detail.
Notable specifications and practical benefits:
- Dual-channel recording:Simultaneous panoramic and PTZ channels mean operators never lose situational overview when zooming; events in the overview can trigger the PTZ to assume track and zoom roles while the overview remains recording.
- Low-light and night performance:The panoramic channel features ColourVu white-light illumination to provide colour images in very low light (colour to roughly 30 m). The PTZ channel uses IR illumination effective to ~100 m for monochrome details at distance. DarkFighter/ColourVu sensor technologies help preserve colour and sensitivity in dim conditions.
- Power and connectivity:PoE+ (802.3at) or 12 VDC power options simplify installation choices; PoE+ reduces cabling for networked deployments. The unit supports standard network protocols (HTTPS, RTSP) and ONVIF for NVR compatibility.
- Smart analytics:Built-in deep-learning analytics include human and vehicle classification, perimeter rules (intrusion, line crossing), region detection, and face capture (up to five faces). These features reduce false alarms and prioritise meaningful events.
- Durability and environmental protections:IP66 ingress rating, operational range from −30°C to 65°C, integrated heater/demist and 6 kV lightning protection make the camera suitable for exposed outdoor sites.
- Storage and audio:MicroSD support up to 256 GB for local failover recording and support for NAS (NFS/SMB/CIFS). Audio in/out and G.711/AAC/MP3 codecs allow for two-way audio or local announcements when needed.
- Operational controls:360° continuous pan and −15° to 90° tilt with 300 presets and patrol/pattern scans give operators flexibility to automate surveillance routines and rapidly respond to incidents.
- Panoramic: 6 MP approx. (3632 × 1632), fixed 2.8 mm, ColourVu white light.
- PTZ: 4 MP (2560 × 1440), 4.8–120 mm, 25× optical zoom, IR to ~100 m.
- Video codecs: H.265 / H.264 / MJPEG with bandwidth optimisations (H.265+, ROI).
- Network: ONVIF, HTTPS, RTSP, 10/100 Mbps Ethernet.
- Environmental: IP66, −30°C to 65°C, 6 kV lightning protection.
Use cases and scenarios where the TandemVu excels
Because it pairs an always-on panoramic view with a high-zoom PTZ, the TandemVu is well suited to spaces where large coverage and forensic zoom are both required. Typical deployments include:
- Road and highway monitoring:The panoramic channel provides context across lanes and medians while the PTZ inspects incidents, reads licence plates at distance (depending on speed and lighting) and follows errant vehicles.
- Transport hubs and stations:In rail stations, bus depots and airports the unit supports crowd monitoring plus the capacity to zoom to suspicious behaviour or items left behind without sacrificing the overall scene.
- City and public-space surveillance:Parks, plazas, and pedestrian precincts need both situational awareness and the ability to examine details for investigations; ColourVu helps keep patrols informed at night with colour imagery.
- Car parks and perimeter security:Wide-area views capture aisle layouts and vehicle movement while the PTZ focuses on incidents, criminal activity or parking disputes, and provides reliable IR illumination for longer distances.
- Critical infrastructure:Power stations, water treatment and industrial sites often require perimeter rules and human/vehicle classification to reduce false positives and improve response workflows.
Comparisons with similar products on the market
In security camera options, buyers typically choose between single-sensor PTZs, multi-sensor panoramic arrays, and hybrid Tandem-style devices. The TandemVu occupies a middle ground with clear advantages and trade-offs:
- Versus single-sensor PTZs:A standard PTZ provides zoom and pan but loses the wide context when it zooms away. TandemVu retains the panoramic channel, so control rooms or VMS systems keep situational awareness while operators zoom—reducing the chance of missing parallel incidents.
- Versus multi-sensor panoramic arrays:Multi-sensor domes stitch multiple fixed sensors to produce ultra-wide, high-resolution coverage but typically lack a high-power optical zoom. TandemVu’s dedicated 25× PTZ outperforms fixed multi-sensor arrays for long-range inspection.
- Versus separate installations (one panoramic + one PTZ):Two separate cameras give maximum redundancy and potentially greater optical reach, but require twice the mounts, cabling and PoE ports. TandemVu simplifies installation and lowers visual clutter at the mounting point while delivering similar functional coverage for many sites.
- Competitor technologies:Similar hybrid solutions are available from several vendors; key differentiators are sensor resolution, illumination approach (white-light ColourVu vs enhanced low-light sensors), analytics sophistication and build quality (heating, lightning protection). TandemVu’s combination of ColourVu panoramic colour at night, long-range PTZ IR, and Hikvision’s analytics is a compelling feature set for many installations.
Customer feedback and testimonials
Public, specific customer testimonials for this exact model may be limited depending on regional sales channels. However, common feedback themes from installations of TandemVu-style and Hikvision TandemVu products include:
- Operators appreciate the persistent panoramic context—knowing what’s happening around a zoomed target reduces missed incidents and improves coordinated responses.
- Integrators report faster installations and cleaner cabling when compared with installing separate panoramic and PTZ cameras, particularly where pole-mounted or façade-mounted deployments are tight on space.
- Security teams praise ColourVu daytime/night colour for better identification in low light, while long-range PTZ IR provides the necessary forensic detail for investigations.
- Some buyers emphasise the importance of matching the camera to a complete system: analytics thresholds, network bandwidth and storage policies need tuning to realise the device’s potential.
If you require direct user reviews, ask your supplier for references or case studies from similar deployments in your region; installers often provide site-specific feedback and sample footage to demonstrate performance.
