In terms of younger companies, I continue to be impressed with Avigilon. It's focus on building a solution tailored to megapixel surveillance is enabling large-scale high definition camera networks to become a reality.
Adding support for analog cameras is an important milestone for them as it now allows mainstream customers to seriously consider using them for broader projects with legacy systems.
Intresting. How do you feel about the issue of recording Megapixel. There seems to be a problem with recording especially long term. Since compression is not an option for megapixel it seems that this is the only problem with the technology.
I agree with you that recording will be a major concern. Similarly, bandwidth as well.
There's no magic bullet but I think you see a number of factors attack the problem over time:
- Exclusion zones. Manually eliminating recording of areas not of interest.
- Analytic filtering: Using analytics to not record areas or times when there are no activity.
- Improved compression: moving from MJPEG to MPEG-4 to H.264 (over time)
- Multi-tiered storage strategies: higher frame rate and resolution for the first x number of days, lower frame rate and resolution for extended storage
- Fall in the price of storage making the sheer volume more tenable (10 years ago with the first DVRs 1 GB was a lot of storage, today we can store 1000 times that amount in an appliance).
I think it's going to take time but the economics of reducing camera costs make such a transition inevitable.
Of course, SA DVR is easiest way to please small customers and are getting more and more cheaper. But big projects where we need more then 50 cameras, PC based DVR is preferable. The only thing we need is expertise in installing various DVR cards ...
I agree with Erik.
The number of criminals actually caught on tape and identified may be lower than we would like, but the number of prevented crimes, due to the presence of cameras and alarms, would be quite impressive, I'm sure, if we actually ...
Non ip based cameras output a composite video signal. Composite output from a cctv camera makes it analog. It's not a digital output like youd find on a network. Composite signals are inherently analog signals, not digital signals. Although you ar...
I understand and agree with most of what you're saying. However, all it takes is someone getting access to that PC/DVR with a game install DVD and all bets are off. Did it rewrite a DLL file you need? Did it modify the registry in a way that makes...
We have put together a pretty extensive list of video tutorials for the GeoVision Control Center V2 System and feel like they should be shared with the physical security world. If you have ever had problems or failures when configuring anything ha...
