Why Choose the S74‑4W‑AHD?
In the world of residential and apartment security, reliability is everything. While wireless and IP systems have their place, nothing beats the stability of a dedicated wired 4‑wire connection. The S74‑4W‑AHD brings you all the modern features you expect – touch control, AHD camera support, inter‑room calling – on a rock‑solid analog backbone that simply works, day after day.
🔌 4‑Wire Stable Connection – Up to 100 Metres
- Separate power and signal lines eliminate interference
- Works over standard 0.5mm wire, up to 100 metres
- Perfect for villas, apartment buildings, and long corridors
- No network configuration, no IP addresses – just reliable wired communication
🖱️ Touch‑Button Control – Modern & Intuitive
The 7‑inch IPS display features responsive touch buttons. Adjust volume, brightness, contrast, and colour with a gentle tap. Even elderly family members find it easy to use.
🎵 Adjustable Display & Ringtone
- Choose from 6 ringtones (adjustable call and ring volume)
- Fine‑tune brightness, contrast, and colour to your preference
- Make the monitor comfortable for any environment – day or night
📹 Monitor 2 AHD CCTV Cameras
Connect up to 2 AHD analog cameras (via 2‑wire cable). Switch between the door station view and additional camera feeds – perfect for monitoring a garden, garage, or second entrance. No need for a separate DVR or monitor.
🗣️ Inter‑Room Call
If you have multiple indoor monitors (e.g., living room and master bedroom), you can make free internal calls between them. Communicate with family members without shouting or using a phone.
🖼️ 300 Built‑in Photos Storage
The monitor has 300‑photo internal flash memory. Even without an SD card, you can capture and review visitor snapshots. For extended storage, insert a microSD card (up to 128GB) for video and photo recording.
🔥 Support Gas & Smoke Detectors
The system can connect to gas detectors and smoke detectors. When an alarm is triggered, the indoor monitor sounds an alert and displays the alarm source – giving your family critical early warning.
