Wireless Sensors
Wireless intrusion sensors including 5800 Series, ProSIX, and PowerG door/window contacts, motion detectors, smoke detectors, and CO sensors. Encrypted RF communication eliminates wiring runs while maintaining supervision and tamper detection.
Plan Your Deployment
- Select sensor frequency and protocol to match the installed panel platform
- Plan RF coverage and signal strength for wall penetration and range
- Specify sensor type per zone: contact, motion, smoke, CO, or environmental
- Evaluate battery life expectations and low-battery reporting intervals
- Confirm encryption and supervision requirements for UL-listed installations
Wireless Sensors — Engineering-Grade Intrusion Detection for Commercial Deployments
This category covers 46 working models of wireless sensors sourced manufacturer-direct or through channel-direct US distribution. Build the rest of your system around the architectural choices below — compatibility, environmental rating, and lifecycle decisions made here propagate through every downstream component you specify.
What to Look For
Detection range and field-of-view drive sensor count. PIR motion sensors cover 30-50 feet at 90-110 degrees indoors; long-range outdoor PIRs reach 150+ feet. Glass-break sensors typically protect a 20-25 foot radius. Match sensor placement to the room geometry and the intrusion paths you're protecting — corners and pet immunity often dictate model choice as much as raw range.
Wired versus wireless changes both reliability and installation cost. Wired sensors give continuous trouble reporting and unlimited battery life but require labor-intensive cable pulls. Wireless sensors install in hours but introduce battery-replacement schedules (typically 3-5 years) and require careful RF planning in steel-and-concrete buildings. Most modern panels accept both transparently.
Environmental immunity matters more in real deployments than detection range. Pet-immune motion sensors ignore animals up to 80-100 lbs; dual-tech (PIR + microwave) sensors resist false alarms from heat sources and air currents. Glass-break sensors discriminate between true breakage acoustics and ambient noise — cheap units false on ordinary household sounds. Choose for false-alarm rate, not just detection sensitivity.
UL listings and code compliance vary by application. UL 1023 covers household-burglar-alarm sensors, UL 639 covers commercial proprietary intrusion. Commercial fire/burglar installations subject to insurance discounts often require ULC-listed (Canada) or UL-listed (US) equipment end-to-end. Confirm the AHJ and insurance requirements before choosing components.

Frequently Asked Questions
What's the difference between PIR and microwave motion sensors?
PIR (passive infrared) detects heat differential of a moving body against a static background; reliable, low false-alarm, low power. Microwave detects motion via Doppler shift of reflected RF — sees through windows and walls, useful for outdoor perimeter, but more prone to false alarms from environmental motion. Dual-tech sensors require both PIR and microwave activation simultaneously and are the gold standard for commercial intrusion.
How often do wireless sensor batteries need replacement?
Most lithium-battery wireless sensors run 3-5 years on a single battery. PIR motion sensors with frequent activations sit at the lower end. Door/window contacts with infrequent state changes can reach 7-10 years. Modern panels report low-battery proactively. Schedule preventive battery replacement at year 3 rather than waiting for low-battery alerts to avoid coverage gaps.
Do I need a cellular communicator?
Almost certainly yes for any insurance-grade intrusion system. Phone-line communication is being deprecated as telcos retire copper; broadband IP communication fails if the burglar cuts power or unplugs the router. Cellular communicators (Verizon, AT&T LTE or 5G) provide independent path-of-last-resort. Many insurance discounts and central-station UL listings now require dual-path (IP + cellular) communication.
Can intrusion sensors integrate with my access control system?
Yes — most modern panels expose REST APIs, ONVIF Profile A, or vendor SDKs that bridge intrusion events to access control and video. Integration depth varies: simple arming/disarming from the access platform is broadly supported, while bidirectional event correlation (intrusion alarm causes camera handoff to monitoring) typically requires the same head-end vendor or a middleware product.
What's the typical false-alarm rate for commercial systems?
Well-tuned commercial intrusion systems run under 1 false alarm per zone per year. Single-tech motion sensors with poor placement can hit 10x that. False-alarm reduction starts with sensor placement and continues with two-factor verification (audio, video) before central-station dispatch. Many municipalities fine commercial sites for repeat false alarms — sustained false-alarm rate above 3 per year per address triggers fees in most jurisdictions.
