Systèmes de caméras de sécurité pour entreprises

A business security camera system includes wired security cameras and a dedicated security recorder (NVR or DVR) that stores, manages, and organizes recorded footage. What makes these systems ideal for business use is their ability to support continuous recording, multiple cameras, centralized storage, remote access, smart analytics, and scalable coverage as your security needs grow.

NVR systems work with IP cameras and use Ethernet cabling with Power over Ethernet (PoE) to deliver power and data through one cable. DVR systems work with analog cameras and use RG59 Siamese coaxial cabling, which combines video and power connections in one cable run. This allows cameras to receive power from a power adapter near the DVR location, so you typically do not need an outlet near each camera. DVR systems are often a cost-effective option for businesses with existing coax wiring or long-distance camera runs.

NVR systems are ideal for modern installations that need high-resolution video, advanced analytics, and flexible expansion. DVR systems are a practical choice for businesses upgrading existing coax-based systems or needing cost-effective coverage over long cable distances.

No. Lorex NVR and DVR systems use local recorder storage, so businesses can record and access footage without mandatory monthly cloud storage fees.

Lorex NVR and DVR systems save footage locally to surveillance-grade hard drives inside the recorder. Included storage can often be expanded with larger hard drives, while select recorders feature dual drive bays for additional storage capacity or mirrored backup. Once storage is full, the recorder automatically overwrites the oldest footage with new recordings, allowing continuous recording without manual file management. Retention time depends on hard drive size, camera count, resolution, bitrate, and recording mode. Use the Lorex Hard Drive Storage Calculator to estimate storage needs based on your system setup and desired retention time.

The number of recorder channels determines how many cameras your system can support. For example, a 16-channel recorder can support up to 16 cameras. 8-channel systems are typically best for smaller businesses, 16-channel systems are a strong choice for growing coverage needs, and 32-channel or higher systems are better suited for large properties, warehouses, or multi-building layouts. You can add more cameras later as long as your recorder has available channels and supports the cameras you want to add.

PoE switches provide additional physical PoE ports for IP cameras, but they do not increase the recorder’s total channel count. They are useful when an NVR supports more cameras than it has built-in PoE ports — for example, a 32-channel NVR with 16 PoE ports. In that case, a PoE switch lets you connect cameras to the remaining available NVR channels through the network. PoE switches can also help simplify cabling layouts and support camera placement farther from the recorder in larger installations.

Yes. Lorex systems allow remote viewing through a Lorex app, so you can view live video, review recordings, receive alerts, and manage system settings from anywhere. This helps business owners and managers stay connected to their property, respond faster to activity, and maintain visibility even when they’re off-site.

No. Wireless cameras do not connect directly to NVR or DVR recorders and operate separately from wired business security systems. However, you can still add indoor or outdoor Wi-Fi cameras, video doorbells, floodlight cameras, and lightbulb cameras as standalone devices — especially when they use the same Lorex app, making it easier to view and manage wired and wireless coverage in one place. Wi-Fi cameras are useful for adding flexible coverage to hard-to-wire areas, temporary spaces, entrances, or locations where quick setup and event recording are more important than continuous recorder-based recording.

Smart analytics use camera intelligence, recorder processing, or both to help detect, classify, and filter activity across your property. These tools can help reduce unnecessary alerts, speed up incident review, monitor occupancy, identify traffic patterns, and support smarter operational decisions. Available analytics vary by system, so always check product specifications for supported features.

Smart analytics vary by camera and recorder model, but may include search tools like Smart Search, operational insights like people counting and heat maps, perimeter tools like intrusion and line-crossing detection, behavior-based alerts like loitering detection, asset protection features like object abandonment and object missing detection, and vehicle-focused tools like License Plate Recognition. These features help businesses find important footage faster, monitor restricted areas, understand movement patterns, protect assets, and improve visibility across key parts of the property.

Yes. Lorex NVR and DVR systems store footage locally on the recorder, helping businesses maintain direct control over recorded video. Your locally stored video and audio recordings remain on your device and are not accessible by Lorex unless you explicitly authorize access for troubleshooting or access is otherwise required by law. Remote viewing through a Lorex app keeps access controlled by the account user, while our security practices include ongoing security controls, vulnerability testing, employee security training, and need-to-know access protections for customer information.

It depends on the system type and cable condition. Existing RG59 coaxial cabling can often be reused when upgrading DVR systems, while NVR systems require Ethernet cabling for IP cameras. Older or lower-rated Ethernet cables may not support the power or performance needed for the latest PoE IP cameras, so cable quality should be checked before upgrading. Coax-to-Ethernet adapters can help reuse existing coax wiring for IP camera installations by converting the coax run into a network connection, reducing the need to pull new Ethernet cable in some retrofit projects.

Standard Ethernet runs for IP cameras typically support up to 300 ft per camera, with longer distances possible using PoE switches, extenders, or ePoE technology depending on the installation. Analog systems can also support long security camera cable runs — often up to 300 ft when using standard power through the cable, or up to 800 ft when cameras are powered locally near the camera.

Common accessories help support installation, storage, expansion, and long-term performance. Depending on your system and layout, you may need:
• Security camera cables to connect cameras to the recorder, extend cable runs, or replace existing wiring
• Surveillance-grade hard drives to expand storage and support continuous recording workloads
• PoE switches and extenders to connect IP cameras to available NVR channels, simplify cabling, or support longer camera distances
• Junction boxes to protect cable connections, conceal wiring, and create a cleaner installation
• Mounts and brackets to position cameras securely on walls, poles, ceilings, corners, or other surfaces
• Coax-to-Ethernet adapters to help reuse existing coax wiring for select IP camera retrofit installations

Yes. Larger systems with outdoor cameras, PTZ cameras, high-resolution cameras, and smart analytics can help monitor parking lots, vehicle movement, entrances, and after-hours activity. Depending on the camera and recorder model, analytics such as vehicle detection, unauthorized parking detection, and wrong-way detection can provide more targeted awareness for parking areas and traffic flow.

Lorex business security systems can support a wide range of environments, including warehouses, retail stores, restaurants, construction sites, offices, hotels, and multi-location businesses. Each use case has different coverage needs — from monitoring loading docks and inventory zones to reviewing point-of-sale activity, supporting safety standards, or protecting equipment after hours.
