Product Overview
The Hikvision iDS-2CD7T46G2/VX3-IHSY(4/12/25mm) is a 4MP DeepinViewX triple fixed-lens bullet network camera engineered for long-range perimeter surveillance. Rather than relying on one lens, it combines a 4 mm 4MP overview channel with additional 12 mm and 25 mm 2MP channels, providing wide, medium and long-range views from the same camera position. DarkFighter 2.0 Sharpmotion technology supports demanding low-light surveillance, while Smart IR provides illumination up to 120 metres. The dedicated Guanlan large-scale AI model supports human and vehicle perimeter classification for line crossing, intrusion, region entrance and region exiting events, with VCA detection reaching up to 120 metres under standard test conditions. Dual microphones, a built-in speaker, red/blue alarm LEDs, alarm I/O and audible warning add active response capability, while IP67, IK10 and NEMA 4X protection on the Y version suit demanding outdoor sites.
Key Capabilities
Triple-Lens Wide-to-Long-Range Coverage
Three fixed lenses operate within the same camera: 4 mm, 12 mm and 25 mm. This provides simultaneous broad, medium and narrow views without forcing a single lens to compromise between situational awareness and distant target detail.
4MP + Dual 2MP Video Channels
Channel 1 records up to 2688 × 1520, while channels 2 and 3 each provide up to 1920 × 1080. All three channels support up to 25 fps in a 50 Hz system at their listed maximum resolutions.
DarkFighter 2.0 Sharpmotion
DarkFighter 2.0 Sharpmotion technology is designed to improve low-light imaging and motion clarity, helping preserve useful perimeter detail when subjects are moving through challenging night-time scenes.
Guanlan Perimeter AI
The dedicated Guanlan large-scale AI model supports line crossing, intrusion, region entrance and region exiting detection with human and vehicle classification, with a specified maximum VCA detection range of up to 120 metres.
120 m Smart IR
Integrated 850 nm Smart IR illumination reaches up to 120 metres, providing long-range night coverage that complements the 12 mm and 25 mm telephoto channels.
Audio & Active Warning
Two built-in microphones, one built-in speaker, red and blue alarm LEDs, audible warning, two alarm inputs and two alarm outputs allow supported smart events to trigger local visual and audible responses.
Best For
- Warehouse and industrial perimeters: Maintain broad situational awareness while simultaneously monitoring more distant fence lines and access points.
- Transport and logistics yards: Triple-lens coverage helps observe nearby activity and distant vehicles from the same mounting position.
- Large commercial compounds: Long-range AI detection and 120 metre IR suit extended boundaries and restricted zones.
- Critical entrances and gates: The 12 mm and 25 mm channels provide greater pixel density on narrower target areas than a conventional wide-angle bullet camera.
- Demanding outdoor environments: IP67, IK10, heater support and NEMA 4X moderate anti-corrosion protection on the Y version provide additional environmental resilience.
Why Choose the iDS-2CD7T46G2/VX3-IHSY
The iDS-2CD7T46G2/VX3-IHSY addresses a common perimeter-surveillance limitation: one fixed lens often cannot provide both a useful overview and sufficient detail on distant targets. Its 4 mm, 12 mm and 25 mm lenses operate as three simultaneous video channels, giving operators wide, medium and long-range views from one housing. DarkFighter 2.0 Sharpmotion, 120 metre Smart IR and the Guanlan perimeter AI model further strengthen low-light and long-distance detection performance. Dual microphones, a built-in speaker and red/blue alarm LEDs add local response capability. Available through Security Wholesalers, it is particularly suited to sites where long boundaries need intelligent surveillance without relying solely on PTZ movement or multiple separately mounted cameras.
Buyer Decision Tips
Buyer Tip: The 4 mm, 12 mm and 25 mm figures are not interchangeable lens options on this specific triple-lens configuration. The camera uses all three fixed lenses together, providing simultaneous wide, medium and telephoto views.
Buyer Tip: Hikvision’s 120 metre VCA figure is a maximum detection distance under standard test conditions and is different from DORI identification distance. The 25 mm channel provides the highest pixel density for distant targets, while the 4 mm channel is designed primarily for wider situational coverage.

Choosing the Right Model
- Choose the iDS-2CD7T46G2/VX3-IHSY if: You need simultaneous 4 mm, 12 mm and 25 mm views, long-range perimeter AI, 120 metre IR and built-in audible/visual warning functions.
- Choose a conventional single-lens bullet camera if: One field of view is sufficient and simultaneous wide, medium and long-range coverage is unnecessary.
- Choose a motorised-varifocal DeepinView model if: You need one remotely adjustable field of view rather than three simultaneous fixed focal lengths.
- Choose a PTZ camera if: Active pan, tilt, patrol and optical zoom movement are more important than continuously retaining all three fixed views.
FAQs
- Is the Hikvision iDS-2CD7T46G2/VX3-IHSY a 4MP camera?
Yes. The camera uses a triple-lens design with three video channels. Channel 1 provides up to 2688 × 1520 resolution, while channels 2 and 3 each provide up to 1920 × 1080. This gives the camera a 4MP primary view together with two additional 2MP views from the 12 mm and 25 mm lenses, allowing broad, medium and long-range scene coverage from one camera position. - Does the iDS-2CD7T46G2/VX3-IHSY include 4 mm, 12 mm and 25 mm lenses?
Yes. The iDS-2CD7T46G2/VX3-IHSY(4/12/25mm) uses three fixed lenses in the same camera: 4 mm, 12 mm and 25 mm. Their horizontal fields of view are approximately 82.5°, 25.4° and 13.0° respectively. This lets the camera maintain a wider overview while also providing progressively tighter views for medium- and long-range perimeter observation. - How far does the infrared illumination reach?
The camera provides Smart IR supplemental lighting with a specified range of up to 120 metres using 850 nm infrared illumination. The 120 metre figure is the maximum illumination range, not a guaranteed identification distance. Practical image detail still depends on the selected lens channel, subject size, atmospheric conditions, scene reflectivity and installation geometry. - What perimeter analytics are built into the camera?
The camera uses Hikvision’s dedicated Guanlan large-scale AI model for perimeter protection. It supports line crossing, intrusion, region entrance and region exiting detection with human and vehicle target classification. The specified VCA detection range can reach up to 120 metres under standard test conditions, helping the camera cover larger boundaries while filtering irrelevant scene activity. - Does the camera support audio and active warning functions?
Yes. The iDS-2CD7T46G2/VX3-IHSY includes two built-in microphones and one built-in speaker, along with two line-level audio inputs and one line-level audio output. It also provides red and blue alarm LEDs and audible warning linkage. These functions can be combined with supported events to provide local visual and audible response at the camera. - How much onboard storage does the camera support?
The camera includes a built-in microSD, microSDHC and microSDXC card slot supporting capacities up to 1 TB. It also supports NAS storage and Auto Network Replenishment. When planning the camera through Security Wholesalers, select storage capacity and card endurance around the actual bitrate, recording schedule and retention requirement rather than choosing capacity alone. - Is the iDS-2CD7T46G2/VX3-IHSY suitable for harsh outdoor environments?
Yes. The camera is rated IP67 for dust and water resistance and IK10 for impact resistance. The -Y version also carries NEMA 4X moderate anti-corrosion protection, while the -H configuration supports operation from -40°C to 65°C. Correct mounting, sealing, grounding and cable protection are still required for a reliable outdoor installation. - Who should choose the iDS-2CD7T46G2/VX3-IHSY?
Choose this camera when a perimeter needs simultaneous wide, medium and long-range views from one position, together with human and vehicle classification, long-range IR and local audible and visual warning. It is particularly suited to warehouses, industrial boundaries, compounds, transport yards and other sites where a conventional single-lens bullet camera would leave gaps between overview coverage and distant target detail.
