Today, we take a look at On Board storage for IP cameras
Potential Benefits:-
Some camera locations have limited or unreliable bandwidth. In those lcoations, ensuring that video can be streamed and recorded remotely can be expensive (or simply not possible). Putting storage inside of an IP camera can eliminate this problem. Of course, some network connections will be needed to remotely view/download record video. However, this will only need to be done periodically.
Cost: While storgae costs drop continuously, today the cost of on-board storage is far higher than centrally storing video in hard drives. Moreover, for most video surveillance applications, it is simply not possible to solely store video on-board IP cameras as it is not technically possible (with the exception of suppliers supporting hard drives inside or attached to their cameras)
- End User Risks
Using on board storage may force compromises in the length of storage or the quality of storage (because of limitations on how much video can be stored inside the camera). Additionally, most VMS systems do not support remote playback of video recorded on an IP camera. This could make it difficult to access and use this video. - Installer Risks
If the on-board storage cannot be remotely accessed using the existing VMS playback, the installer may be called for additional service calls. Some systems will require a technician physically remove the on-board storage while others will require downloading raw video files.

we at IntegratedCCTV agree in part with the report – however, we still think that a camera recording in a continuous loop, just enough to cover a 3 9’s network (99.9% allowable down time, 43 minutes per month) and then using technology such as March Networks’ Shadow Archive feature, means that the system can synchronise video lost during the network downtime, with little effect on the overall system…………this is new and probably not known at the time of the report, but it is worth noting when discussing the above!!!
