Doesn’t Every IP Camera Record?
Posted by Mark Espenschied on Jun 05, 2017 in Technology
Some
people fail to grasp the excitement of an edge camera (an edge camera surveillance
system, or as we like to call it CaaS™ — Camera as a System).
“My IP
cameras have SD slots,” they say. “What’s the big deal?”
Before
I get to the big deal, understand that your camera only records to an internal
SD card as a backup when disconnected from the network (and if you program it to
record in that circumstance).
Okay. The
big deal is — how are you going to retrieve that video?
The
answer to that question is, you are going to send someone out to the camera and
retrieve the SD card. Maybe that will require a ladder. Maybe that will require
a lift.
Then,
you are going to put the SD card into a computer to access the video.
Finally,
somebody is going to watch the video and analyze whether anything of note happened
while the camera was offline.
“So?”
you ask. “What is different about an edge camera?”
An
edge camera is its own video surveillance system. There is a lot going on
inside. In the case of DW®® MEGApix® CaaS™ Edge
Cameras, the camera is running DW Spectrum® IPVMS server and can
record constantly to its internal card.
In
fact, if that one camera is all you need, access the system with a DW Spectrum®
client and you are in business. Review the video on the card using DW Spectrum®’s
robust search and analytic tools. Back the data up to another drive. Export the
video. Treat the edge camera like you would any other DW Spectrum® IPVMS
video surveillance system.
Now,
what if you have a lot of cameras in your DW Spectrum® IPVMS system
and the edge camera is a lone ranger out in the hinterlands? You may not
monitor the edge camera all the time. When you do need to see what it captured,
you simply merge it as a system with your other DW Spectrum® IPVMS
system and now that camera can be managed as part of the larger video surveillance
system.
My
last question: So what about our original scenario? What if you have the MEGApix®
CaaS™ Edge Camera merged with your main DW Spectrum® IPVMS video
surveillance system all the time? What are the benefits to that?
Pretty
huge, actually.
Picture
this. Your MEGApix® CaaS™ Edge Camera loses contact with the network
for some reason. As long as it has not lost power, it will record to its
internal card.
Once the
MEGApix® CaaS™ Edge Camera reconnects with the network, the video it
recorded will sync with where it stopped recording to the server storage and
you can playback the timeline seamlessly as DW Spectrum® pulls simultaneously
from both the edge camera’s SD card and the server storage.
Pretty
slick. Oh, you can also export the complete timeline in perfect synchronization. You can, that is, if you are using a Digital
Watchdog® MEGApix® CaaS™ Edge Camera and DW Spectrum®
IPVMS.
What
can you do with your edge camera and VMS?
Your
IP cameras might record as an emergency backup, but they are far from being
edge devices – cameras that are their own surveillance systems.
