New from J&J
J&J Sentinel™ NVRPatent Pending
A video recorder with S.I. built in. It records your cameras and watches them for people, vehicles and animals, so you review the moments that matter instead of hours of footage. Installed and supported by J&J Technical Services.
What it does
Less scrubbing. Faster answers.
Sentinel runs on a PC on your network and works with the IP cameras you already have or the ones we install. S.I. detection points out activity as it happens, and every alert links straight to the recording.
Features
Everything in one recorder
S.I. detection
Tags people, vehicles and animals as they happen. Turn it on or off for each camera; cameras with it off still record.
Faces
Search recorded faces and build watch lists so you can find a person across cameras and time.
Plates (LPR)
Reads license plates on cameras aimed for it, with search and plate alerts. Works best on a camera set up for plates.
Alert review
Every alert has a snapshot and a jump-to-playback link, so you can confirm or dismiss it in seconds.
Heatmaps
See where people and vehicles spend time: entrances, aisles, lots and loading docks.
Remote access
View live and recorded video from your phone or another PC, behind a login.
Sites & compliance
Group cameras by location, set retention, and keep an audit trail.
Viewer & updates
A view-only Viewer app for other PCs (live wall and footage, no settings), plus in-app updates you install in a couple of clicks.
Industry packs
Set up for how your business runs
Each pack sets up detection rules and alerts for a type of site. Turn on the ones you need. Items marked assistive flag things for a person to review.
Large Retailers & Big-Box Stores
Checkout lane queues, exit-without-paying flags (assistive), exit-door receipt checks matched to the sale, possible missed-scan flags at registers (assistive), loitering at locked cases, stockroom after hours, dock doors left open, long-gun alerts at entrances and a lockdown workflow.
Retail & Convenience
Register queue length, left-without-paying flags (assistive), cross-store tracking and assistive weapon alerts. Receipt checking: each sale's receipt shows on the register camera's video and is searchable with a jump to playback, plus alerts for voids, refunds, no-sales and large sales.
Restaurants & Bars
Back door and walk-in alerts after hours, drive-thru timing, long-gun alerts at entrances and a lockdown workflow.
Casinos
Works today with Sentinel's existing rules: two-person rule and after-hours alerts for the cage and count room, loitering alerts, parking garage after hours, one-button lockdown and assistive weapon alerts. Optional banned-patron alerts from your own face watch list, off by default and only where your state's privacy rules allow.

Next build: escaped-animal alerts when a horse or dog leaves its area, fence-line crossing alerts when horses or other livestock come into a pasture from outside, marking your own horses and dogs so they don't set off alerts, and high-priority dangerous-predator warnings, starting with bears. Planned: high-priority warnings for mountain lions, bobcats, wolves and coyotes, and 64- to 128-tile video walls.
Farm & Ranch
Livestock outside the fence, gates left open, night barn watch that flags an animal lying still too long or pacing (assistive), trespassers, equipment leaving at night, and feral hogs or predators near livestock.

Medical & Patient Care
Nurse call with a test button, per-room two-way audio, patient and fall alerts in one list (alerts come from connected cameras or devices that send them; Sentinel doesn’t detect falls itself), and temperature-camera setup with an over-temperature alert (default 100.4 °F). Readings come from the camera itself: a screening aid only, not a diagnosis.
Prisons & Jails
Works today with Sentinel's existing rules: doors held or propped open, tailgating at secure doors, people in restricted areas after hours, loitering alerts, one-button lockdown and assistive weapon alerts. Recording stays on your own on-site server. Still in the works for the full corrections pack: fight and fall alerts, crowding alerts, officer rounds and access-control tie-ins.
Straight answers
What to expect
- S.I. detection is a tool, not a guarantee. It can miss things or flag things that aren't there, so every alert links to the video for you to check.
- Plate and barcode reading need a camera placed and focused for it. A wide overview camera won't read them reliably.
- Camera systems come in sizes of 4, 8, 16, 32, 64 and 128 cameras.
