Pet Immune Motion Detectors
Pet immune motion detectors are designed to help reduce false alarms caused by pets moving through protected areas. They are a practical option for households where cats or dogs are present and internal alarm detection is still required.
- Reduced pet-related false alarms – Designed to distinguish between expected pet movement and potential intruder movement, subject to model limitations.
- Suitable home alarm option – Useful for living areas, hallways and other spaces where pets may move while the system is armed.
- Wired and wireless options – Choose from selected hardwired or wireless pet immune detectors depending on the system.
- Correct placement matters – Mounting height, furniture, stairs and pet size can all affect performance.
Learn more about pet-friendly home security systems and how pet immune detectors can help reduce unwanted alarm activations.
Pet-friendly tip: Pet immune detectors are not a guarantee against all false alarms. Correct placement, pet size, climbing furniture and detector settings should be reviewed carefully.
Wired vs Wireless Hills Motion Detectors
Hills-compatible motion detectors are available in wired and wireless options. The right choice depends on the alarm panel, receiver, building layout, installation method and whether cabling is practical.
| Detector Type | Advantages | Common Use |
|---|---|---|
| Wired Motion Detectors | Reliable hardwired connection, suitable for traditional alarm installations and new cabling runs. | Homes, offices, shops and commercial premises where cabling can be installed neatly. |
| Wireless Motion Detectors | Flexible installation with less cabling required, subject to compatible wireless receiver and panel support. | Finished homes, renovations, upgrades or locations where cabling is difficult. |
| Dual-Technology Detectors | Uses more than one detection method to improve stability in selected environments. | Areas where standard PIR detection may be less suitable due to environmental conditions. |
| Quad PIR Detectors | Designed to support stable and accurate motion detection. | General internal alarm coverage where reliable detection is important. |
