Why is the RK315DTWatchOUT microwave infrared intruder insensitive and short range?
A: The RK315DT is a multi-function alarm. It has a mounting height of 1-2.7 meters and a range of 90 degrees X 15 meters (default lens). It is also equipped with pet-proof, channel-type, and barrier-type lenses. Slide the PCB in the inner seat to the corresponding position according to the height table (1m, 1.5m, 2.2m, 2.7m) printed on the bottom left corner of the PCB. The green light represents the microwave, the yellow light represents the passive infrared, and the red light represents the alarm. If the green light is off and the yellow light is off, the detector will not report an alarm. The reason is that the passive infrared does not detect the alarm signal. It must be resolved by adjusting the sensitivity of the passive infrared. If the yellow light is off, the detector will not alarm. The reason is that the microwave The alarm signal is not detected and must be solved by adjusting the microwave sensitivity.
What are the advantages of WatchOUT's digital correlation technology over other composite intruder detectors with 2 PIR channels?
A: In other outdoor probes with 2 PIR channels (such as Optex, Crow, Paradox), if different events (simultaneous) trigger each PIR channel, it will cause false alarms.
WatchOUT's digital correlation technology prevents false alarms from different events because it compares signals between channels. Signal mismatch caused by different events was cancelled.
Why do you say WatchOUT has 2 MW channels? I only see 1 MW module.
A: WatchOUT's microwave module has 2 different channels; each frequency generates a separate Doppler pulse, which is a separate channel. The 2 channels are used to distinguish the forward and backward movement targets. Note: There are 4 electrical connections from the module to the PCB; 2 per channel. The general single-channel MW module has only 2 connections.
Why does the instruction not recommend pointing the detector to a wobbling object; does it mean that the wobbling recognition technique does not actually work?
Answer: Shake recognition technology does work. However, to obtain the best detection, it is recommended to avoid pointing the detector to the shaking object if possible. If there is no other choice, then the shaking object should be at least 5M away from the detector (16'), as shown in the figure.
Thermal energy reaches the PIR sensor through optical pathways such as lenses or mirrors, which are placed inside the element. PIR sensors usually include two IR elements that convert IR (infrared) energy into voltage.
There are two reasons for this: First, intruders may use shaky objects as a cover to hide themselves because the shaking objects cause a decrease in the MW sensitivity in the vicinity.
Second, palm trees with large leaves may swing beyond the allowable net distance. In extreme cases, it may cause detection on the PIR channel, causing false alarms. The "shake" sensitivity cannot be set to low because this will allow the intruder to pass through the path of the detector and not be caught.
In short, shaking recognition virtually eliminates false alarms due to shaking objects, the degree of which is determined by the need to capture the intruder. In tests conducted in areas that wobbled trees, WatchOUT did not generate false positives, which was in contrast to the high false positives produced by detectors without 2 MW channels.
What is WatchOUT's pet avoidance limit?
A: The pet avoidance limit is 70cm animal head height. Any animal whose head height is lower than this will not be hidden in two separate PIR channels at the same time. There is no weight limit as we set for other Rokonet pet protection detectors.
When should I use a special pet for low installation to prevent the lens?
A: This lens is required when pets are required to prevent and the installation height is less than 1.7m. The lens has a special optical design to ensure that pets are prevented from false alarms when installed in low places.
How do weather conditions such as rain, snow or fog affect the performance of WatchOUT?
A: The above weather conditions should not adversely affect the performance of WatchOUT. Neither MW nor PIR channels are affected. Fog does not affect the PIR detector, although it will have a negative impact on active infrared. If it snows, the detection performance may increase because snow reduces the background temperature and the temperature difference between the intruder and the background increases. In addition, WatchOUT provides a cover to avoid direct sunlight and prevent rain droplets from leaking onto the lens.
Why is installation flexibility so important in outdoor installations?
A: The importance of the installation flexibility of an outdoor detector cannot be underestimated because it is a prerequisite for optimal detection and high false alarm avoidance. If the method of installing the detector is inconsistent with the terrain, the detection performance will be low, resulting in a high false alarm rate. The contractor will benefit from WatchOUT's installation flexibility because it allows them to easily provide a perfect match to the protected terrain; thus providing the best performance.
Can WatchOUT detectors face each other or install back to back?
Answer: Yes. WatchOUT probes have MW anti-collision functionality and can therefore be allowed to do so. This saves wiring time and is particularly beneficial for barrier applications.
How does the MW anti-collision feature work?
A: The anti-collision function works automatically without any code or jumper settings.
It is enabled through 2 MW frequencies as follows:
The MW pulse is emitted during the duty cycle controlled by the crystal. The crystals in each detector are slightly shifted in time and randomly shifted. The 2 MW frequencies can "feel" the MW interference from other detectors and "skip" in time to avoid collisions.
How are camera options available?
A: When ordering a camera option, the camera comes with a Watch OUT cap. Only this cover is provided with the camera and it will fit any type of WatchOUT, saving logistics, inventory and part numbers.
It should be noted that the 4-line camera connection and the detector connection are separate. 2 lines are for power supply and 2 lines are for analog video. A single camera power supply is also available for purchase. It is not provided automatically with each camera. This saves on customer costs because the contractor usually provides common power for all cameras in the field.
