Surveillance systems typically rely on the the VMS to report issues, but this most often just means knowing a camera is "down" with no warning or detailed information.
Network monitoring systems can give users more insight into their network, from the camera to the switch to the VMS server, but are seen as too complex or expensive to be used in simple surveillance systems.
However, significant practical benefits can be gained by understanding these monitoring platforms, with free software available, and minimal setup time.
In this guide, we take a look at network monitoring specific to surveillance, explain the basics and software available, and give real practical examples of its use.
The Milestone XProtect Corporate and Expert platforms have MIB files available. They are not available from our website but they can be retrieved from the two locations below after the software is installed:
On the Management Server: C:\Program Files\Milestone\XProtect Management Server\SERVER-MIB.mib
On the Recording Server: C:\Program Files\Milestone\XProtect Recording Server\RECORDER-MIB.mib
1. I think it would be good to address the various versions (v1/v2/v3) of SNMP, with v3 the only secure version. Using v1 for example might allow an attacker to find out which switches and firmware you are running and thus which attacks will be successful (if you are not up to date with updates). Most if not all major camera brands support v3.
2. We have been using Zabbix for a few years now which works fine, and is open source and therefore free.
3. Some caution when using SNMP: depending on number of devices, number of sensors, uodate frequency, you might generate a lot of network traffic.
PRTG is definitely the best. If you consider the TCO, it's the cheapest NMS as well. Don't waste time on Nagios or similar systems unless you have highly knowledged system administrators on salary and not loaded with the tasks.
Timely article. As a traditional MSP, network design, installation, and monitoring is the heart of our expertise, and they're a set of skills we're looking to bring to the IP camera realm. Earlier this year we decided to enter the space, and also partnered up with an existing installer who like us, sees the value of monitoring and maintenance services.
SNMP is great for system level metrics but it has limited use understanding traffic or quality statistics for video flowing over a network. Of course a vendor could build this in but I havent seen it yet.
I still didn't get what you want to see. If by lost video data you mean dropped frames, then you need VMS or client to monitor that (and reply to NMS via SNMP as an option). But if you're talking about regular IP packet loss, that is easily monitored using SNMP.
