MeshDynamics provides the network infrastructure to make a fully distributed IP surveillance system possible for cameras, video servers, storage clusters, custom applications and remote viewing to be located in any location. 

The Department of Homeland Security (DHS) and SPAWAR engineers selected MeshDynamics Wi-Fi mesh nodes to provide remote video surveillance for stationary and vehicle mounted cameras along the US national border. IP cameras are connected to the MeshDynamics MD4000 mesh nodes transmitting high resolution real time video over the mesh network to the base station video monitors. Live video feeds from the IP based cameras is also available via the MeshDynamics mesh network to patrol vehicles with wireless access. Mobile nodes mounted in security forces vehicles join the network dynamically and while in motion. Service radios in the vehicles provide connectivity for staff in vehicles and operating nearby. In similar applications, UK, Israeli and Canadian defense agencies have also selected MeshDynamics for wireless video surveillance applications in those countries. [Customers]

MeshDynamics nodes were also selected for remote monitoring of heavy mining machinery and in military programs involving mobile cameras mounted on army vehicles. Competing products were tried in these challenging video surveillance applications. They were  unsuccessful due to unacceptable latency and jitter as deployments scaled (e.g. more hops, more cameras, mobile transmissions). 
 
Distinctive features of MeshDynamics' MD4000 modular mesh node framework (specific to Video Surveillance) include:

Assured Low Latency and Jitter Earlier-generation mesh networking products perform poorly in multi-hop (node-to-node relay) environments.  MeshDynamics' patented low latency multiple radio wireless mesh technology preserves high performance [over multiple hops] that's been available only in wired networks until today. US Defense Agencies has validated these claims [More]

Up to 216 Mbps Throughput: MeshDynamics 4-radio slot products enable multiple radio backhauls to fork from one mesh node The dual downlink root node model 4452 and 4454 support 44 Mbps TCP/IP (108 Mbps Raw) and 88 Mbps TCP/IP ( 216 Mbps Raw) back to the surveillance control station, respectively. That is 2-4X the number of cameras supported by competing mesh products. And MeshDynamics patented third generation mesh performance does not degrade as networks scale and hops increase. 
    
Robust Security Features: Extensive data security capabilities are provided, including WEP, WPA, WPA2, 128 bit AES encryption, 802.11i, and FIPS 140-2. Extensive VLAN and performance-tuning features are also standard, including support for 802.11e (for radio level QoS), protocol-based forwarding, and hidden SSIDs. [More]

Effistream^TM For Glitch Free Real Time Video Transmission: MeshDynamics Network Management System (NMS) provides users the ability to ensure real time streams (e.g. VOIP and Video) are handled differently along the mesh. The result: glitch free real-time video over mesh networks. [More]
