Hikvision TandemVu vs. Uniview Dual Lens PTZ Tested
Dual-imager PTZ camera models are a growing niche with Hikvision and Uniview both offering them, but how well do the cameras work, and how does their performance compare?
IPVM bought and tested the Hikvision TandemVu DS-2SE4C425MWG-E PTZ and the Uniview IPC94144SR-X25-F40C to compare, and in this report, we include our tested results, including:
- How does image quality compare in full light (~180 lux)?
- How does image quality compare in ~1 lux or ~5 color low light scenes?
- How does image quality compare in dark scenes with IR and/or White Light on?
- How well is the analytics performance in full light and low light scenes?
- How does the face capture performance compare?
- How well does the Uniview Auto-Tracking work on people and vehicles?
- What is the PPF required for reliable people and face detection?
- What, if any, indoor or outdoor sources caused false alerts?
- How even or uneven was the white light spread and intensity?
- How even or uneven was the IR spread and intensity?
- How does pricing compare?
- How does bandwidth consumption compare, day and night?
- How well do the cameras integrate into ACC, ExacqVision, Genetec, Milestone, and NxWitness?
Note: Dahua offers Dual Imager PTZs but they are not being sold in North America so we omitted to avoid issues with us testing an unofficial/unsupported model in our region.
