The REDWALL SIP series is a range of long-range outdoor PIR sensors designed to be connected to PTZ or fixed cameras and trigger the CCTV system when an intrusion occurs. As with any detector, it is important to be aware of the installation guidelines to avoid any performance issues with the sensor’s detection capabilities.
Our tech team provide their top tips to resolve the three main issues which installers have experienced when getting false alarms or short range on the Redwall SIP sensors:
- Dip switch configuration for detection logic
- Mounting height
- Alignment and Masking
Watch the video below for a thorough explanation by our Technical Engineer - Jeyi Greene.
1. Dip switch configuration for detection logic
The REDWALL sensors will be shipped in walk test mode and dip switch number one will be in the ON position. This is so that you can easily test that each zone has an output. Once you have determined each zone works correctly, you then need to switch it DOWN to turn OFF.
2. Mounting Height
For all passive detectors to work efficiently they need to be mounted within the recommended height so that the majority of target activity is across the detection area. For the REDWALL series, the mounting height is between 2.3m and 4m. On the neck of the unit there is an arrow which points towards two notches, if the unit is mounted at 4m the arrow should be pointing to the lower notch. If the unit is mounted at 2.3m, the arrow needs to be pointed at the upper notch. If the unit is mounted in between 2.3m and 4m, then the arrow should be pointed in between the notches.
3. Alignment and masking
The REDWALL SIP series are long-range passive infrared detectors. They can detect from 30m to 100m, and if the individual unit is not properly aligned and masked it will create unwanted detections. Each SIP sensor comes with a detection template which needs to be used with the AVF-1 alignment tool for you to properly align and mask the unit. The detection template is contained in the SIP-AT kit.
After you have adjusted the detection area using the area viewfinder, always check the area using the walk tester.
Tech tip: SIP-AT: An essential tool kit to install the REDWALL SIP PIRs
26 November 2021
When installing the Redwall SIP outdoor PIR series, it is essential to be equipped with the SIP tool kit SIP-AT, which provides a number of masking plates to suit the detection area, enables the sensor’s mounting angle to be adjusted to validate the detection area with audio walk test.Read More
