Hikvision DS-2CE78D0T-LTS(2.8MM) — 2MP Two Way Audio Fixed Turret Camera
The Hikvision DS-2CE78D0T-LTS(2.8MM) is a 2 MP outdoor-rated turret camera built for live, two-way voice communication rather than passive recording alone. It pairs a built-in microphone and 2 W speaker so operators can listen in and speak directly through the camera to warn off intruders or communicate with visitors in real time. Night visibility is handled by Smart Hybrid Light, switching between IR and white light up to 40 m, while an IP67-rated metal-and-plastic housing makes it suitable for both covered outdoor spots and indoor installations. It runs on HDTVI signal output over standard coaxial cable, making it a practical fit for existing Hikvision Turbo HD DVR setups.

- Outdoor and semi-exposed installations — verandas, carports, and covered outdoor walkways where the IP67 rating protects against rain and dust that indoor-only cameras can’t handle
