Restaurants are one of the most common commercial installs we do on Long Island — and one of the trickiest. The kitchen is hot, greasy, and never quiet. The dining room needs to feel welcoming, not surveilled. The back door is a security weak point. The POS is where shrinkage happens. Here's what a good modern restaurant security system looks like.
The back door is the single most important camera in a restaurant. It's where deliveries arrive, where staff comes and goes, and where after-hours break-ins happen. Mount a wide-angle 4MP+ camera with strong night vision pointed at the door from outside, ideally combined with a card-reader or PIN-pad door lock that logs every entry/exit.
Owners want to know — without playing detective — whether transactions are being voided, items are being comped without authorization, or cash is being mishandled. A camera over each register, angled to capture the cash drawer and the customer counter, integrated with the POS system to overlay transactions on the video, makes this kind of review fast and clear.
Cameras in the kitchen serve two purposes: workplace safety (slip-and-fall liability, knife injuries, equipment misuse) and operational visibility (timing, training, accountability). Equipment matters here — kitchen cameras need to be sealed against grease, heat, and humidity. We use IP66-rated cameras for kitchen installs.
Dining room cameras are the easiest part to get wrong. Customers don't want to feel watched. We typically install discreet dome cameras at corners with wide enough angles to cover the room without making any specific table feel monitored. The point isn't to watch customers — it's to have video if there's a slip-and-fall, a dispute, or an incident.
A standard burglar alarm with door/window sensors and a couple of motion detectors covers most break-in scenarios. Modern systems are cellular (no phone line needed), arm/disarm from the manager's phone, and integrate with the camera system so an alarm event can pull up the relevant clip automatically.
Replacing the back-door lock with a code-based or card-based reader is one of the highest-value upgrades for a restaurant. You stop worrying about who has keys (because nobody does), every entry is logged, and you can deactivate codes when staff leave. Pairs with the back-door camera so you can see the face that goes with each entry.
Required by code in commercial kitchens and dining rooms. We install IP/PoE fire alarm systems for new restaurants — modern, monitored, and integrate cleanly with the rest of the security stack.
Pricing varies widely with restaurant size and complexity, but for a typical 2,500–5,000 sq ft Long Island restaurant:
Total for a comprehensive restaurant install: typically $6,000–$11,000 depending on size, layout, and complexity. Less for smaller operations or quick-service concepts.
