The Dahua DHI-ARD323-W2(868S) compact wireless door sensor is a miniature version of the classic magnetic detector for protecting doors, windows and hatches. The reduced dimensions make the device unobtrusive on thin frames and decorative elements, without disrupting the aesthetics of the interior. Two-way communication and frequency-hopping technologies at 868 MHz ensure stable operation in a saturated radio environment.
Advantages
- Compact housing — minimal dimensions allow the sensor to be installed where a standard one would not fit: narrow frames, thin profiles, furniture doors
- Unobtrusive installation — small dimensions preserve the aesthetics of the interior and do not attract attention
- Reliable 868 MHz communication with FHSS — protection against jamming and interference, stable operation in apartment buildings and office centers
- Two-way radio communication — confirmation of delivery of every alarm signal to the security panel
- Charge and temperature monitoring — timely warnings about maintenance without sudden failures
- Signal level detection — checking the coverage zone at the installation stage for optimal placement
Applications
- Apartments with designer renovation — concealed installation on doors and windows without disrupting the interior
- Office premises with thin partitions and glass doors
- Cabinets, safes and storage cells — protecting valuables in hard-to-reach places
- A supplement to standard sensors where a compact solution is required
