Milestone Edge Storage

[Tambra Podrasky]

TheONVIF driver supports retrieval of remote recordings from a device (edge storage) using ONVIF Profile G. The communication protocol for Edge Storage is always RTSP. When the device is configured to live stream on RTP/RTSP/HTTP/TCP, the protocol for retrieval of recordings will be RTSP over HTTP, otherwise it will be RTSP. When RTSP over HTTP is selected and HTTPS is enabled the retrieval will be done using RTSP over HTTPS.

If one of these does not show in the Management Client or the Smart Client, then this means that Edge Storage is not available and therefore some of the important services are not implemented by the device firmware.

The retrieval of Video, Audio and Metadata is done in three steps. When a retrieval of specific time interval is requested first a video recording is searched for and then retrieved. After that is complete, audio is searched for and retrieved. Then last, metadata recording is searched for and retrieved.

The ONVIF driver supports retrieving recordings from the device with the following codecs: JPEG, MPEG4, H.264, and H.265. The ONVIF driver supports retrieval of edge storage video from multichannel video devices (multiple video sources) as well as retrieval from single channel devices. For the details of the edge storage retrieval flow see section Edge Storage retrieval workflow page Edge Storage retrieval workflow and for technical requirements a multichannel device needs to fulfil see section Requirements for Edge Storage on Multichannel devices. page Requirements for Edge Storage on Multichannel devices..

The ONVIF driver supports retrieval of remote audio recordings with the following audio codecs: G.711, G.726, and AAC. This is applicable for single channel and multichannel devices. Support for single channel audio edge storage is available since XProtect Corporate 2018 R1* and Device Pack 9.6. Multichannel audio edge storage is available since Device Pack 9.7. For more technical information see sections Edge Storage retrieval workflow and Requirements for Edge Storage on Multichannel devices..

Edge Storage refers to the ability of modern IP cameras to record video and audio to embedded or removable onboard media storage devices instead of, or in addition to, streaming media to a centralized recording server. Milestone XProtect VMS supports the retrieval of edge storage recordings and features several ways to maximize system reliability, flexibility, and performance when using edge storage to complement centralized recording.

To alleviate XProtect's inability to utilize Bosch's "Forensic Search", I would like to use iSCSI (or VRM) as the primary recording medium with XProtect Professional+; however, I cannot get XProtect to retrieve edge recordings from a microSD card - let alone iSCSI. In this scenario, I would fall-back to a Bosch video client for analytic searches.

I am willing to read any technical document, knowledge base article or forum post, but I cannot find noteworthy information about setting up XProtect to utilize Bosch's edge storage capabilities via SD card or iSCSI.

The configuration for this device was done in Bosch's Configuration Manager and the camera's webpage. Bosch Video Recording Manager or Bosch Video Management System was never utilized or connected to this camera during this process. The camera was set to factory defaults, time server set to mirror the XProtect's server's SNTP settings, provisioned the SD card on the cam's webpage, and enabled recording in Bosch Configuration Manager.

As edge storage is continuously recording on the camera, I disconnect the VM's network adapter and reconnect it after approximately five minutes. When the virtual adapter is reconnected, the camera is instantly restored in the Live tab of Smart Client and recording proceeds again to the recording server's local disk. XProtect will not retrieve recordings that are available on the microSD card (automatically via rules or manually with Time Selection Mode); the retrieval job status is "completed", but edge recordings are not populated in the timeline or available to replay.

I can retrieve the SD card and iSCSI footage from the device's webpage and Bosch viewing clients. Repeating the same procedure, I can successfully retrieve video from a G6 Sony PTZ (SNC-WR632) with firmware 2.7.3.

It looks like you did your homework! I can't see in your post that you've done anything wrong. The only thing I can think of off the top of my head is that some cameras require that you specify in the Management Client whether edge recording is event based or continuous. Reason being is on some cameras it determines which method is used to retrieve video from the camera. This setting is either in the camera or hardware properties within Management Client and doesn't necessarily exist for every camera. If it's there, try toggling it.

While this won't have anything to do with this issue, I just wanted to mention that for automatic retrieval after a camera connection is restored, you don't need any rules. Just tick the check box at the bottom of the record tab for the camera in Management Client. The check box is named "Automatically retrieve remote recordings when connection is restored".

One other thought I had was Windows Firewall. It might be for this camera that the retrieval is streamed over UDP while you're live stream might be TCP. I have seen that particular behavior before. And I have seen Windows Firewall block inbound UDP streams even when disabled. So you might try adding a rule in the advanced firewall settings allowing all inbound UDP traffic from the camera (typically on port 554). For testing purposes, it makes sense to make the rule broad (all ports from the camera's IP) and if that's the issue, tighten it up afterwards.

I tested another Bosch camera (Autodome) and success was sporadic with both devices (the aforementioned Flexidome) via iSCSI and SD card. Matter of fact, I had this working with the devices tied to VRM.

Recording onto an SD card is important for video security cameras because it ensures that footage is not lost in the event of a power outage or other interruptions. Edge recording also saves space on the card, as it does not require as much storage as traditional video recording methods.

Setting up continuous recording on SD cards is a great way to ensure your video footage will be there when you need it. Enabling edge recording on Milestone XProtect provides an added layer of protection. By using both camera-based and central storage methods, you create an efficient solution that will help reduce total costs and maximize performance.

For millennia, this awe-inspiring region has been home to Indigenous Peoples, including First Nations, Alaska Natives and Coastal Tribes. Their cultures, languages, stories and livelihoods are directly connected and interwoven with the land and seascape. Indigenous Peoples are the original and remain the most important stewards of the Emerald Edge, both now and for generations to come.

Carbon offsetting entails reducing or removing greenhouse gas emissions in one place to compensate for emissions elsewhere. Through carbon markets, carbon offset projects can sell or trade a carbon credit for each metric ton of carbon dioxide (or equivalent) to emitters to help accelerate overall carbon reduction goals.

The many tools available to reduce emissions include public policy, corporate action, market transitions toward renewable energy and transforming transportation, among others. As Cors adds, these efforts must complement the swift and immediate reduction of GHG emissions worldwide. In addition, the emerging tools of carbon offsets and markets, when implemented to high standards, can ensure that the carbon in forests like those in the Emerald Edge is protected and can bring much-needed revenue to local communities and conservation efforts.

In addition to exploring carbon offsets, TNC uses private philanthropy and public spending to finance nature-based carbon sequestration and climate resilience projects in the Emerald Edge. And TNC and community partners are co-developing other non-carbon-offset pathways, such as sustainable economic development, eco-tourism and clean energy projects, to scale, sequester or reduce carbon pollution across the region while centering community priorities.

Delvin explains that, in this region, forests are buffered from major disturbances like the fires and drought occurring in other parts of North America. And the forest and carbon programs are well-regulated through robust state and provincial rules, meaning TNC and partners can have confidence that the carbon will stay in the trees and that, when carbon offset projects are put in place, their impact is real and will provide that additional benefit to the climate, ecosystems and communities.

Amidst decades of conflict and devastating corporate-driven deforestation in British Columbia, two areas of the Emerald Edge in this Canadian province are now serving as a shining example of Indigenous-led conservation and climate action, ranging from ground-breaking forest carbon projects to a total ban on grizzly bear hunting.

A key turning point came in 2009, in the Great Bear Rainforest region along the west coast of British Columbia, when an alliance of coastal First Nations and the provincial government launched one of the largest carbon offset projects in the world, and the first Indigenous-led carbon project in North America. This was later strengthened with the signing of Atmospheric Benefit Sharing Agreements that give First Nations the ownership and right to sell carbon offsets in local and international carbon markets. Today, the Great Bear Forest Carbon Project sequesters 1 million tons of CO2e per year, and the sale of carbon credits is helping First Nations protect the forest from industrial logging, support their ecological and cultural values, and build economic self-sufficiency.

In 2016, the Great Bear Rainforest Agreements pledged to conserve 19 million acres of land that is home to many First Nations, including making 9 million acres completely off limits to logging. This is one of a series of joint commitments between the provincial government and First Nations that began in 2006. One of the earliest direct outcomes of these Agreements was the creation of Coast Funds, combining an endowment fund that supports Indigenous-led conservation and an economic fund that supports Indigenous-led economic activities compatible with conserving the Great Bear Rainforest and the Haida Gwaii archipelago.
