Pair an S200 motion sensor with your camera, tune sensitivity, and place alerts where they catch real movement instead of false triggers.
Quick answer
Pair the sensor and camera on the same 2.4 GHz Wi-Fi network first, then mount the sensor and tune sensitivity before you rely on alerts. A motion sensor camera setup works best when the sensor covers the approach path, not the camera's own field of view, so alerts fire before someone reaches the door.
Before you start: what to check on your network and gear
Both the S200 motion sensor and the CAM100 camera list 2.4 GHz Wi-Fi (IEEE 802.11 b/g/n) in their specs, so confirm your router broadcasts a 2.4 GHz band and that your phone is on it during setup. The S200 runs on one CR123A battery with a 20uA standby current, so install the battery before pairing and expect roughly one year of use at 25 triggers a day or two years at 10 a day. The CAM100 supports SD cards up to 128GB, which matters because alerts alone do not save footage; without a card you only get the notification.
Placement rules that cut false alerts
The S200 detects across a 7m distance and a 110° angle, with a 45m wireless range to the network. Aim that 110° cone across a walkway or driveway approach rather than at a wall or window, and keep it out of direct sunlight and away from heating vents, since it is rated for 0-40°C and 20-40% operating humidity. The CAM100 needs to be within 10m of what it watches for usable infrared night vision, so if your sensor covers the gate, the camera should still have a clear line to the same zone.
What to do when alerts keep firing
Most repeat false triggers come from sensitivity set too high for the space, not from a faulty sensor. Lower the sensitivity threshold before you move hardware, then check whether the trigger source is heat, moving foliage, or a passing car. If the sensor and camera are on different Wi-Fi bands or the sensor sits near a metal door, the 45m wireless range can drop sharply and delayed alerts look like missed motion.
Step-by-step setup
- 1. Power the sensor and camera: Insert the CR123A battery into the S200 and power the CAM100. Wait for both to finish their startup blink sequence before opening any app. Checkpoint: if the sensor does not blink at all, reseat the battery before troubleshooting the app.
- 2. Connect both devices to 2.4 GHz Wi-Fi: Add each device in the app while your phone is on the 2.4 GHz band. Both the S200 and CAM100 list IEEE 802.11 b/g/n only. Mistake to avoid: joining a 5 GHz network, which these devices do not support.
- 3. Pair the sensor to the camera or hub: Follow the in-app pairing prompt and keep the sensor within a few feet of the camera during pairing, then move it to its final spot. Checkpoint: confirm the sensor shows as online in the app before mounting it.
- 4. Mount the sensor at the approach path: Angle the 110° detection cone across the walkway or driveway, roughly 7m of coverage, and keep it out of direct sun and away from vents. Mistake to avoid: aiming the sensor at the camera's own view, which duplicates coverage instead of adding early warning.
- 5. Tune motion detection sensitivity: Start mid-range, trigger a test walk-through, then lower sensitivity if pets, cars, or foliage set it off. Checkpoint: one clean trigger per deliberate walk-through is the target.
- 6. Test alerts and recording together: Insert an SD card up to 128GB in the CAM100, walk through the zone, and confirm you get both the notification and a saved clip. Next step: if alerts arrive but no clip saves, check the card before changing sensor settings.
Product facts that affect setup
- S200 Motion Sensor - Responsive Infrared Security System, Rotatable, Realtime Alerts: S200 motion sensor: CR123A battery, 20uA standby, 7m detection distance, 110° angle, 2.4 GHz Wi-Fi, 45m wireless range. The 7m/110° cone and 45m range define where the sensor can sit relative to your router and the area you want covered.
- CAM100 Remote Control High Resolution Smart Home Security 1080p Camera with Motion Detection: CAM100 camera: 1080p, 2.6mm F2.0 lens, IR distance 10m, SD card up to 128GB, 2.4 GHz Wi-Fi. The 10m IR distance limits night coverage, and the SD card slot is what lets you review the clip an alert points to.
