Best Home Security Systems for Pet Owners 2026

Pets and security systems have an uncomfortable relationship: a standard motion sensor doesn't distinguish between a 180-pound intruder and an 80-pound dog. False alarms from pets frustrate homeowners, desensitize them to alerts, and can lead to police false-dispatch fees. The right system for pet owners gets motion detection right and gives you indoor cameras to check in without triggering an alarm.

Quick verdict: Vivint is the best system for pet owners — professionally configured pet-immune sensors, indoor cameras with two-way audio, and smart home automation rules that can distinguish between pet movement and alarm events. SimpliSafe is the best DIY alternative with a genuine pet-immune motion sensor option for pets up to 50 lbs.

Key takeaways

Pet-immune motion sensors use PIR heat profiling to ignore animals below a set weight — but aren't perfect for large breeds.
Entry-point sensors (door/window contacts) are completely unaffected by pets and should anchor any pet-owner security setup.
Indoor cameras with two-way audio let you check in on pets without triggering alarms.
Mounting sensors high (6–7 ft) and angling down significantly reduces pet-triggered false alarms.
Always inform your monitoring company you have pets — it affects alarm response protocol.

Top picks for pet owners

Vivint

Best for pet owners overall

Vivint's professionally installed pet-immune sensors are configured by your installer for your specific pet size and behavior patterns. For cats and dogs under 100 lbs, properly installed Vivint sensors virtually eliminate pet-triggered false alarms. Vivint's indoor cameras offer two-way audio for checking in on pets, and smart home rules can auto-bypass specific zones when the system arms in Away mode.

Best for: Pet owners who want professional configuration, large dogs, multiple pets · Not for: Budget buyers — Vivint's monitoring starts at $29.99/month

SimpliSafe

Best DIY pick for pet owners

SimpliSafe's Motion Sensor Pro includes pet-immune sensitivity settings for animals up to 50 lbs. It's the best option for DIY pet owners with cats and medium-sized dogs. For large dogs (60+ lbs), consider placing motion sensors in rooms your dog doesn't access and relying on door/window sensors for perimeter protection.

Best for: Cat owners, small-to-medium dog owners, DIY buyers · Not for: Large dog breeds (over 50–60 lbs) — pet immunity is less reliable at higher weights

View →

Ring Alarm

Best for pet camera monitoring

Ring Alarm doesn't offer dedicated pet-immune sensors, but its indoor cameras (Ring Indoor Cam) with two-way audio work excellently as pet monitoring cameras. Motion zones let you define exactly which areas of a room to monitor — useful for ignoring your pet's regular movement paths. Combined with Alexa routines, you can automate camera checks.

Best for: Pet camera monitoring, cat owners with predictable movement areas, Amazon households · Not for: Large dog owners who need reliable pet-immune motion detection

View →

Abode

Best for smart automation with pets

Abode's CUE automation engine lets you create rules that automatically bypass specific sensors or zones when a pet is home alone. This is more flexible than traditional pet-immune sensitivity — you can define exactly which sensors to bypass on Away mode. Combined with Z-Wave-compatible pet feeders and smart home devices, Abode is the most automation-friendly option.

Best for: Smart home enthusiasts with pets, automation-focused households · Not for: Beginners — Abode's automation depth requires technical setup

Frequently asked questions

What is a pet-immune motion sensor? +

A pet-immune motion sensor uses PIR (passive infrared) technology configured to ignore heat signatures below a certain weight threshold — typically 40–80 lbs depending on the setting. It detects the larger heat profile of a human while filtering out smaller animals. Note: they are not foolproof — a large dog near the sensor can still trigger it.

Which security system has the best pet-immune motion sensors? +

Vivint and SimpliSafe both offer pet-immune motion sensors. Vivint's sensors can be configured by your installer for specific sensitivity. SimpliSafe's Motion Sensor and Motion Sensor Pro both offer pet immunity settings for pets up to 50 lbs. Most other DIY systems don't offer genuine pet-immune options.

How do I prevent false alarms from my pets? +

Use pet-immune motion sensors rated above your pet's weight. Mount motion sensors high (6–7 feet) and angle them downward — this reduces the field of view at floor level where pets move. Avoid placing sensors in narrow hallways or near cat trees or furniture your pet climbs. Entry-point sensors (door/window) are not affected by pets at all.

Can I use security cameras to monitor my pets while I'm away? +

Yes — indoor cameras from SimpliSafe, Ring, and Vivint all work well as pet monitoring cameras. Look for two-way audio (to speak to your pet), wide-angle lens for room coverage, and motion detection with app alerts. Eufy and Wyze are cost-effective choices specifically for indoor pet monitoring without subscription fees.

Do I need to tell my security company I have pets? +

Yes — inform your security provider so they can configure motion sensor sensitivity appropriately and note it in your monitoring account. This helps reduce false alarm dispatches and prevents unnecessary police calls when your pet triggers a sensor.
