DS-2CD3743G2-IZS product overview
A protected 4MP motorized-varifocal dome camera for scenes that need remote field-of-view adjustment. Its 2.7 to 13.5 mm lens, human and vehicle filtering, 120 dB WDR and audio and alarm interfaces support controlled entrances and exposed commercial sites.
Key features
- 4MP imaging up to 2688 x 1520
- 2.7 to 13.5 mm motorized varifocal lens
- Horizontal field of view from 102 to 31 degrees
- Human and vehicle detection
- Infrared illumination up to 40 m and 120 dB WDR
- IP67 and IK10 protected housing
Best-fit applications
- Commercial entrances and loading areas
- Vandal-prone public or transport locations
- Warehouses and building perimeters
- Backlit scenes needing adjustable framing
Compatibility and pre-order checks
- Measure scene width, mounting distance and target size before setting the motorized lens; zoom cannot correct an unsuitable camera position.
- Verify recorder support for 4MP streams, event filtering, audio, alarms, onboard storage and the intended search workflow.
- Confirm PoE or 12 VDC power, mounting accessories, weather sealing, impact exposure and surge protection.
- Confirm the exact regional firmware, interface requirements and microSD capacity before procurement.
Frequently asked questions
Can the lens be adjusted after installation?
The listing specifies a motorized 2.7 to 13.5 mm lens, allowing remote framing within its range. Final focus and target detail still require an on-site test.
Does it support local recording?
The listed microSD slot supports capacities up to 512 GB. Confirm card compatibility and configure health monitoring, retention and overwrite behavior.
What is the benefit of IK10 protection?
IK10 indicates a listed impact-resistance level for the housing. Correct mounting and cable protection remain necessary in exposed locations.
