What PerimeterEye does differently
Each one next to what SimpliSafe says about its own products, October 2026.
Nobody watching your cameras
No agents or guards watch them: the AI on the Brain decides and acts, and the alert comes to you. Your 24/7 recording stays on the Brain at your property; on paid plans the cloud AI analyzes events and keeps event clips.
At SimpliSafeOn Active Guard, an agent watches the live feed when a camera flags someone; agents also see video during an active alarm.1
A searchlight that follows them
The Brain turns a motorized searchlight onto the person and keeps the beam on them as they move, with 355° of rotation and 90° of tilt. Every package with a searchlight runs on Brain Full, for full tracking.
At SimpliSafeThe Outdoor Camera Series 2 has a spotlight that lights up to 10 feet in front of it.5
24/7 recording, even on Free
The Free plan records every camera 24/7 on the Brain, with 4K clips of every event, alerts, live view and rewind. Free is $0 for good, and paid plans are month to month.
What SimpliSafe sells, and what PerimeterEye sells
The two lineups, row by row: SimpliSafe's models, specs and prices from its own pages, PerimeterEye's from the Shop.
| What is compared | SimpliSafe | PerimeterEye |
|---|---|---|
| The brain of the system | The Base Station, the alarm's hub and siren, with up to 24 hours of backup battery and a built-in network backup.11215 | Brain Full: the AI for 1-16 cameras, 1 TB of recording (about 20 days of 24/7 video from 4 cameras) and full searchlight tracking. Brain Lite: 1-12 cameras and 256 GB; it tracks more slowly and less accurately. Both record 24/7 at your property on every plan, Free included. |
| Outdoor cameras | The Outdoor Camera Series 2: 1080p, a 140° view, 10x digital zoom, a spotlight and a 90 dB siren, on its battery or power cable. Indoors, the Smart Alarm Wireless Indoor Camera records at 1536p.514 | Model 804, in white. 8 MP (4K) with a 2.8 mm starlight lens, full-color night vision, a microphone and speaker for two-way talk, and a metal housing, on one network cable. |
| The front door | The Video Doorbell Series 2: 2K video, a 150° view and a 70 dB siren, on your doorbell wiring; $199.99 at launch.816 | Model 704. A video doorbell and intercom with door codes and cards that rings your phones and wall panels. The AI Doorman greets visitors and takes messages on AI Guard. |
| Light | The Outdoor Camera's spotlight lights up to 10 feet for color video at night; on outdoor agent plans, it's kept for the agent to use.5 | A motorized searchlight with 355° of rotation and 90° of tilt, sold with its 90 W PoE injector: the Brain turns the beam onto the person and keeps it on them as they move. It sweeps the property on a schedule, and you can tap a camera's picture to aim it. Full tracking on Brain Full; slower on Brain Lite. |
| Siren | The Base Station's siren, an Extra Siren at 105 dB for indoors or out, and the cameras' sirens: 90 dB outdoors, 70 dB on the doorbell.51516 | 130 dB with a strobe, on one network cable. The AI siren sounds by itself on serious threats with Standard and up; on any plan you can sound it from the app. It stops after 30 seconds and tells you. |
| Inside the home | Entry, motion, glass-break, smoke and CO, water and temperature sensors, a keypad, key fob and panic button, in packages from The Foundation (4 pieces) to The Haven (14).19 | Model 604. A touchscreen on the wall for live cameras and rewind, modes, the siren and the searchlight, and the front door. Instead of door and window sensors that react when a door or window opens, PerimeterEye is built to answer the person outside, before they reach a door, and it can run alongside an alarm you already have. |
| Power and connection | Wi-Fi, with a cellular backup for the alarm on professional plans. SimpliSafe says all its cameras need Wi-Fi to work.1213 | 8 PoE ports and 2 uplinks at 120 W, and Cat 6 cables in 25, 50 and 75 ft: one cable per device carries its power and video. Every package comes with the switches and cables it needs, so the prices here are for spares. The Brain switches to Wi-Fi if its cable drops. |
| Who answers | Alarm agents text and call you, and request police if they can't reach you. On Pro and Pro Plus, Active Guard agents watch the live feed when a camera flags someone while the alarm is on, and can talk, sound the siren, shine the spotlight and request police, on up to 3 cameras.134 | None needed. It answers on its own, day and night: nobody has to watch or step in, not even you. The alert and video still reach your phone. |

What each one does, step by step: SimpliSafe's from its own pages, PerimeterEye's as filmed. An illustration, not a timed test.
SimpliSafe
- The Outdoor Camera or Video Doorbell spots a person while the alarm is on, during the plan's hours.15
- An agent starts watching the live feed. SimpliSafe says agents can assess and react in less than 30 seconds.1
- The agent talks through the camera, then can sound its siren and shine its spotlight.1
- If there's a threat to safety, the agent requests police help.1
A person's judgment through the camera, once an agent is on the feed.
PerimeterEye
- The camera sees a person, and the AI on the Brain reads what they are doing, where, for how long and at what hour.
- The searchlight turns onto them and keeps the beam on them as they move.
- The AI voice describes them and tells them to leave: “You, black hoodie, get away from the car now.”
- If they stay, the 130 dB siren sounds. Your phone already has the alert with live video.

From the door handle to the searchlight, on film.
On the camera's own clock, 21:04:26 to 21:04:30. Nobody pressed anything: the camera saw it, the Brain judged it, and the searchlight landed on the person.
Filmed September 15, 2026. Live PerimeterEye demonstration. Real footage. Real-time autonomous detection, tracking, and deterrence.
21:04:26Contact with the door handleThe person reaches for the driver’s door. The analysis builds second by second: a person, no match to anyone it knows, loitering at the vehicle, and now contact with the door handle. 
21:04:29Car theft in progressThree seconds after the door handle, the analysis is complete: the activity doesn’t match the household’s patterns and matches vehicle theft. All systems activate. 
21:04:30The searchlight landsThe searchlight hits the person at the driver’s door. The alert reads: spotlight, voice warning and siren activated, with a tap to cancel the escalation. 
21:04:31Running, and the beam followsFive seconds after touching the door handle, the person is running down the drive, and the searchlight has moved with them, away from the car.
What SimpliSafe publishes
It times something different: SimpliSafe's figure is people responding; PerimeterEye's is the searchlight reaching the person.

PerimeterEye and SimpliSafe: questions buyers ask
Is Active Guard the same as PerimeterEye's AI voice?
No. Active Guard is a person: when a camera flags someone while the alarm is on, a SimpliSafe agent watches the live feed and can talk, sound the siren and shine the spotlight, on up to 3 cameras, 24/7 on Pro Plus or 8 p.m. to 6 a.m. on Pro. PerimeterEye's voice is the AI on the Brain, describing the person on any camera, with the searchlight already on them and the 130 dB siren next. The AI voice warning and AI siren come with Standard and up.
Can I install PerimeterEye myself, like a SimpliSafe kit?
Yes. It comes with full instructions, or you can hire an independent installer and pay them directly. Each camera, searchlight and siren runs on one network cable, so plan the cable runs first.
Does PerimeterEye record without a plan?
Yes. On Free, the Brain records every camera 24/7, with 4K clips of every event, alerts, live view and rewind. SimpliSafe records camera video only on a plan that includes it, Core and up or its camera-only recording plan; its Standard plan records none.
Which is better for an apartment?
Usually SimpliSafe. With little ground outside, door, window and motion sensors cover the real risk, and its kits move with you. PerimeterEye is built for properties with a driveway, a yard or long approaches, where things start outside.
Does anyone have to watch the cameras?
No. PerimeterEye answers on the property by itself, in seconds: the searchlight locks on, the AI voice warning describes the person, and the siren sounds if they stay. Nobody watches your cameras, and the alert and live video reach your phone at the same time. The AI voice warning and AI siren come with Standard and up.
