IP Security and Surveillance
Enhanced IP Camera Video Surveillance Solutions
CCTV technology has evolved exponentially—from simple video footage monitoring, to today’s intelligent systems that are capable of identifying abnormal events or behavior.
As intelligence increases in CCTV systems, so do technology applications. Surveillance technology can now be used to observe consumer behavior, to help organizations increase their revenue and profitability, and to monitor retail environments to reduce shrinkage.
This document explains some of the benefits of intelligence in IP surveillance systems, and the advantages of working with Allied Telesis IP video surveillance solutions.
The diagram shows that it is easy to save, search, edit and analyze video, using a PC. The networked cameras send digital image data through an IP network, where the video feed can also be monitored on a smartphone.
High-definition images
High-definition digital images are sharper and clearer than the lower resolution images typically produced by analog surveillance cameras. Digital video can be stored on a variety of media—PC hard drives, Network-Attached Storage (NAS) systems, and more. Digital images do not degrade, regardless of how long they are stored. Furthermore, they can be searched quickly, even if large volumes of data have been stored.
Simpler operation
Depending on the system, it is possible to monitor the digital video feed with standard PC software. The images are stored as MPEG or H.264, so selected video segments can be uploaded to cloud-based storage, to be displayed or analyzed from anywhere.
Video analytics
Video surveillance analytics can assess security-related events using data about foot traffic, face recognition and reconstruction of events from several camera sources. The Allied Telesis IP Surveillance Solution effectively achieves these benefits and provides secure, remote monitoring for further security assurance. Many everyday monitoring tasks can be automated, with a low rate of errors.
Simple installation and cabling
By using Allied Telesis Power over Ethernet (PoE) switches, power can be provided to cameras over the same Ethernet cable as data, removing the need for separate power cables. The camera needs just a single UTP Ethernet cable run to it from its local switch. This simplifies the installation process.
As a result, even after the initial installation of the system is complete, any subsequent alteration or expansion of the surveillance network is also simplified.
Flexible deployment
Allied Telesis Industrial switches operate in a wide temperature range, so they are perfectly suited to outdoor video surveillance applications. All models support the 30 watts of PoE+, and some can provide 60 watts of power to end devices. This enables the latest outdoor Pan Tilt Zoom (PTZ) cameras with heaters/blowers to be connected and powered over a single Ethernet cable.
Continuous camera operation
Allied Telesis innovative Continuous PoE (CPoE) keeps cameras recording. CPoE is a unique feature that guarantees uninterrupted power delivery to cameras and other sensors, even when the switch is rebooted. CPoE lets switches perform actions such as software upgrades without forcing cameras to power cycle. Cameras that support local storage resync to the network when connectivity is back.
Utilize existing network infrastructure
For new installations, existing cabling can be incorporated to make network upgrades more cost effective. For example, existing coax cable can be reused to transport modern digital data.
To reuse coax cable, two MMC6006 Ethernet Extenders are used. The extenders are connected at either end of the cable, with one unit configured as a local device, and the other as a remote device. This enables surveillance cameras in remote locations, which may be hard to reach with new cabling, to connect over existing coax to the IP Ethernet network.
