Product SKU: DS-2CD2T126G3-IS2UY-SL-EF
Product Overview
The Hikvision DS-2CD2T126G3-IS2UY/SL/eF 12MP AcuSense Bullet Camera combines ultra-high-definition imaging, advanced target classification and active deterrence in a robust outdoor housing. Its 1/1.8-inch progressive scan CMOS sensor captures up to 4608 × 2592 resolution, while Powered by DarkFighter technology and 130dB true WDR help retain detail in low-light and strongly backlit scenes. AcuSense 3.0 classifies human and vehicle targets for supported events, reducing alerts caused by irrelevant movement. A white strobe light, built-in Smart PA speaker and arrayed dual microphones support audible and visual warning, while 60m infrared illumination, MicroSD storage, audio and alarm interfaces, PoE+, IP67 and NEMA 4X protection suit demanding residential, commercial and industrial surveillance applications.

AcuSense 3.0 helps prioritise people and vehicles, while the white strobe and Smart PA speaker can respond immediately to configured perimeter events. Powered by DarkFighter, 130dB WDR, electronic image stabilisation and 60m infrared support challenging lighting and exposed mounting positions. Built-in dual microphones, two-way audio, alarm input/output and edge storage provide additional integration options. Security Wholesalers supplies this model for professionally designed Hikvision surveillance systems.
Buyer Decision Tips
Buyer Tip: Confirm the supplied lens before ordering. The product family is available with 2.8mm, 4mm and 6mm fixed lenses, with each option providing a different field of view and target distance.
Buyer Tip: Use a compatible NVR that supports 12MP recording, AcuSense events, two-way audio, alarm interfaces and sufficient incoming bandwidth for the selected bitrate.
Power Note: The camera requires IEEE 802.3at PoE+ or a suitable 12V DC supply. Standard low-power PoE ports may not provide enough capacity for all functions.

FAQs
- What resolution does the DS-2CD2T126G3-IS2UY/SL record?
The camera records at up to 12MP resolution, measuring 4608 × 2592 pixels, at up to 20fps. It can record at higher frame rates when configured for 8MP or selected lower resolutions. - What does AcuSense 3.0 detect?
AcuSense 3.0 classifies human and vehicle targets for supported motion and perimeter events. Correct configuration helps reduce alerts generated by rain, vegetation, changing light and other irrelevant movement. - How does the active deterrence function work?
The /SL camera can activate its white strobe light and built-in speaker when a configured event occurs. Warning sounds, messages, schedules and linkage rules should be adjusted to suit the site and local requirements. - Does the camera support two-way audio?
Yes. It has an arrayed dual-microphone system and a built-in Smart PA speaker, allowing compatible live-view software or recorders to support two-way communication. Separate line-level audio input and output connections are also provided. - How far does the infrared night vision reach?
The infrared illumination is rated for up to 60m. Actual usable range depends on the selected lens, target size, mounting angle, nearby reflective surfaces, weather and ambient lighting. - Which fixed lens should I choose?
The 2.8mm lens provides the widest view, the 4mm option offers a balanced general-purpose view, and the 6mm lens provides a narrower view with more detail on distant targets. Confirm the exact lens included with the ordered SKU. - Is the camera suitable for outdoor and coastal use?
The camera has IP67 weather protection and NEMA 4X anti-corrosion protection. Hikvision classifies it for moderate anti-corrosion requirements, so highly aggressive marine or chemical environments may require a top-level specialist model. - What should I check before purchasing this camera?
Confirm the lens, target distance, NVR bandwidth, 12MP recording capability, PoE+ capacity, audio and alarm support, strobe-light suitability and storage requirements. Security Wholesalers can supply this model for compatible professional Hikvision surveillance systems.
