CCTV Network Requirements Guide for Lebanon — 2026

Networking Is the Backbone of Modern CCTV

Modern IP-based CCTV systems in Lebanon depend entirely on the underlying network infrastructure. Unlike legacy analog systems that used coaxial cable, IP cameras require Ethernet connectivity, PoE power, adequate bandwidth, and proper storage infrastructure. A poorly designed network leads to dropped frames, corrupted recordings, and cameras that go offline during critical moments. This guide covers the networking requirements for CCTV deployments in Lebanese homes, offices, retail stores, and commercial buildings.

Bandwidth Requirements Per Camera

Each IP camera consumes a constant stream of bandwidth. The exact amount depends on resolution, compression, and frame rate:

Most cameras run dual streams: a high-resolution main stream for recording and a lower-resolution sub-stream for live viewing. Add both streams when calculating total bandwidth per camera.

Bandwidth Calculation Example

A typical Lebanese retail store with 8 cameras at 1080p H.265 at 15 FPS:

• Main stream: 8 cameras x 2 Mbps = 16 Mbps
• Sub-stream: 8 cameras x 0.5 Mbps = 4 Mbps
• Total: 20 Mbps — well within a single Gigabit uplink

A 32-camera commercial building at 4K H.265 at 15 FPS:

• Main stream: 32 cameras x 6 Mbps = 192 Mbps
• Sub-stream: 32 cameras x 1 Mbps = 32 Mbps
• Total: 224 Mbps — requires careful switch selection with sufficient backplane capacity

PoE Switch Selection for CCTV

Power over Ethernet (PoE) eliminates the need for separate power adapters at each camera location. Choose your PoE switch based on camera count, power requirements, and uplink needs:

For 1-8 Cameras

• MikroTik CSS610-8P-2S+IN: 8 Gigabit PoE ports with 140W total budget, plus 2x 10G SFP+ uplinks. 802.3af/at support. Fanless desktop form factor. The SFP+ uplinks provide future-proof connectivity to the NVR or core switch. A strong choice for small to medium CCTV installations.
• MikroTik CRS112-8P-4S-IN: 8 Gigabit PoE ports with 4 SFP cages. 150W PoE budget. RouterOS management for VLAN isolation of camera traffic.

For 8-24 Cameras

• MikroTik CRS328-24P-4S+RM: 24 Gigabit PoE ports, 500W budget, 4x 10G SFP+. Rackmount 1U. Handles 24 cameras while providing headroom for higher-power PTZ cameras that draw more watts. The 10G uplinks connect to the NVR server without bottlenecks.
• Ubiquiti USW-Pro-24-PoE: 24 Gigabit PoE ports, 400W budget, 2x 10G SFP+. UniFi management. Ideal if the rest of the network already uses UniFi equipment.

For 24-48+ Cameras

• MikroTik CRS354-48P-4S+2Q+RM: 48 PoE ports with 4x 10G SFP+ and 2x 40G QSFP+. For large commercial buildings, warehouses, and multi-site CCTV aggregation.
• Ubiquiti USW-Pro-48-PoE Gen2: 48 PoE ports, 600W budget. For large UniFi Protect installations.

Network Design for CCTV

Separate VLAN for Cameras

Always isolate CCTV cameras on a dedicated VLAN. This prevents camera traffic from competing with office internet traffic, and it prevents unauthorized access to cameras from the general network. Configure VLAN tagging on your switch and create a separate subnet (e.g., 192.168.10.0/24) for all cameras.

NVR Placement

The NVR (Network Video Recorder) should connect to the same switch as the cameras via a 10G SFP+ link or a LAG (Link Aggregation Group) of multiple Gigabit ports. This prevents the NVR from becoming a bandwidth bottleneck when recording all cameras simultaneously while users access live feeds.

Cable Infrastructure

• Use Cat6 UTP cable for camera runs. Maximum distance: 100 meters from switch to camera.
• For cameras beyond 100 meters, use fiber with media converters or PoE extenders.
• Use outdoor-rated shielded cable for any exterior camera runs. Install surge protectors on all outdoor camera cables.
• Plan cable routes during building construction or renovation — retrofitting structured cabling in Lebanese buildings with concrete walls is expensive and disruptive.

Storage Calculation

Recording storage depends on camera count, resolution, compression, frame rate, and retention period. Formula:

Storage (GB) = Bitrate (Mbps) x 3600 x 24 x Days / 8 / 1000

Example: 16 cameras at 1080p H.265 at 15 FPS (2 Mbps each), 30-day retention:

• Total bitrate: 32 Mbps
• Storage: 32 x 3600 x 24 x 30 / 8 / 1000 = 10,368 GB (approximately 10.4 TB)

Add 20% overhead for filesystem and recording gaps. A 12 TB NVR drive handles this installation. For longer retention or 4K cameras, scale storage proportionally — 4K cameras at H.265 require roughly 3x the storage of 1080p.

Power Backup for CCTV in Lebanon

CCTV systems must operate during power outages — security threats do not pause when the electricity goes out. Ensure:

• The PoE switch runs on a UPS with sufficient runtime (minimum 2-4 hours for bridge-to-generator scenarios)
• The NVR has UPS protection to prevent recording corruption during abrupt power loss
• Outdoor cameras with IR illumination draw more power at night — size your PoE budget and UPS for nighttime power draw, not daytime

A dedicated PoE Router UPS can keep a small camera system running during extended outages without a full server-room UPS.

Remote Viewing Over the Internet

Most Lebanese CCTV users want to view cameras remotely from their phone. Network requirements:

• Upload bandwidth: each remote viewer needs 2-4 Mbps of upload bandwidth per camera stream viewed. Lebanese ISP upload speeds are often limited — check your upload capacity before enabling remote access for multiple users.
• Dynamic DNS: use MikroTik Cloud DDNS or a third-party DDNS service to reach your NVR despite changing IP addresses.
• VPN access: the most secure approach is to connect via VPN (see our MikroTik VPN guide) and access the NVR through the encrypted tunnel rather than exposing it directly to the internet.
