Surveillance
Outdoor CCTV Wireless Backhaul Solution
Outdoor CCTV deployment using wireless bridges and PoE switches to backhaul IP camera video 1-20km without cable runs — for parking lots, perimeters, farms, and construction sites
The Challenge
Outdoor surveillance installations require cameras in locations far from the network closet — parking lots, fence perimeters, building rooftops, farms, and remote gates. Running Ethernet cable over long distances costs $10-30 per meter for trenching, requires permits, and is sometimes physically impossible across roads or waterways.

Our Approach
MossLink's outdoor surveillance solution pairs PoE switches with 5.8GHz wireless bridges to deliver network connectivity and power to remote camera locations up to 20km away. Bridges with built-in PoE output power cameras directly. AI Watchdog PoE switches auto-reboot frozen cameras. All equipment is IP65/IP67 rated for continuous outdoor operation.
The Challenge
Security teams need cameras in difficult-to-reach outdoor locations: parking lot perimeters, remote gates, building rooftops, and fence lines. Traditional wired installations require long cable runs, ground trenching, and conduit — driving up project costs and timelines.
Environmental factors add complexity: equipment must withstand rain, dust, extreme heat, and freezing temperatures year-round.
Our Approach
MossLink replaces long cable runs with wireless bridge links:
Long-Range Links (500m - 5km): MKL-WB5800 point-to-point bridges connect remote camera clusters to the main network over distances up to 5 km with line of sight. IP66 enclosures handle any weather.
Short-Range / Elevator Links: MKL-WB3600 compact bridges serve elevator shafts, short courtyard crossings, and locations where a single camera needs wireless backhaul.
PoE Infrastructure: MKL-SW8P managed switches at each camera cluster location power multiple cameras and the bridge unit from a single power source. VLAN segmentation isolates surveillance traffic from other network services.
Architecture Example
A typical parking lot deployment:
- MKL-SW8P PoE switch in the server room powers the first bridge
- MKL-WB5800 bridge pair links the server room to a remote pole
- Second MKL-SW8P at the remote pole powers 4-8 IP cameras
- All video traffic is tagged on a dedicated surveillance VLAN
- NVR in the server room records all feeds over the bridge link
Bandwidth Planning for Video Surveillance
Camera resolution directly determines bridge throughput requirements. Plan your bridge links with these baselines:
- 1080p H.265 cameras: 4-8 Mbps per camera
- 4K (8MP) H.265 cameras: 12-20 Mbps per camera
- PTZ cameras with continuous recording: 15-25 Mbps per camera
A single MossLink WB630 bridge (900 Mbps throughput) comfortably handles 8-12 HD cameras or 4-6 4K cameras on one link. For larger clusters, the WB5AXH6-35 (2400 Mbps) supports 20+ cameras with headroom for NVR remote access and configuration traffic.
Always reserve 30% bandwidth margin for peak bitrate spikes during motion events, IR switching, and firmware update pushes.
PoE Switch Selection for Outdoor Camera Clusters
The PoE switch at each camera cluster is the power and data hub for the entire remote site. Key selection criteria:
PoE Budget: Each camera draws 7-15W typical, 25W peak with heaters or IR. A 4-port switch with 60W budget powers 4 standard cameras. An 8-port switch with 120W budget handles 8 cameras plus the bridge unit.
Extend Mode: MossLink S402E switches support 250-meter Extend Mode at 10 Mbps — useful for cameras placed beyond standard 100m Ethernet reach without adding a second switch.
AI Watchdog: The switch pings each connected camera at configurable intervals. If a camera stops responding, the switch automatically power-cycles that port. This eliminates truck rolls for frozen cameras in remote locations.
Outdoor Enclosure: The S402E-Outdoor model ships in an IP65-rated housing for pole or wall mounting at the camera cluster — no need for a separate weatherproof junction box.
Why MossLink for Surveillance Projects
Security integrators and CCTV distributors choose MossLink for several reasons:
- Bridge + PoE switch bundles ship as tested, pre-configured kits ready for field installation
- Built-in PoE output on select bridge models (WB451H) powers one camera directly from the bridge — no switch needed for single-camera locations
- All outdoor equipment is IP65/IP67 rated and tested for -30°C to +65°C continuous operation
- OEM branding: your logo on the bridge, switch, and packaging for project bids and resale
- Factory-direct pricing from Shenzhen with 15-30 day lead times for 100+ unit orders
Results
Wireless bridge-based surveillance networks eliminate the majority of outdoor cabling costs while providing reliable, high-bandwidth video backhaul. The modular design means additional camera locations can be added by deploying another bridge pair — no trenching required.
Frequently Asked Questions
How many cameras can one wireless bridge support? A 900 Mbps bridge (like the WB630) handles 8-12 HD cameras or 4-6 4K cameras. For larger clusters, the WB5AXH6-35 (2400 Mbps) supports 20+ cameras. Plan for 30% bandwidth headroom above aggregate camera bitrate.
Can I use wireless bridges for elevator CCTV? Yes. MossLink 2.4 GHz bridges (WB2F01) are specifically designed for elevator shaft installations where wall penetration matters more than speed. They deliver 300 Mbps — sufficient for 2-4 elevator cameras — with auto-pairing and 12V PoE.
What happens if a camera freezes on a remote PoE switch? MossLink AI PoE switches (S402E, S802E) detect unresponsive cameras via ICMP ping and automatically power-cycle the affected port. The camera reboots within 30-60 seconds without a site visit.
How far can a wireless bridge reach for CCTV backhaul? Standard panel bridges reach 3-5 km with clear line of sight. High-gain dish models (WB5ACDish-Pro, WB5AXH6-35) reach 15-30 km. Most surveillance projects fall within 1-5 km where standard bridges perform excellently.
