Testing OzVision 4-HVR VSaaS / Video Verification

Author: Benros Emata, Published on Sep 21, 2010

Using existing analog cameras and implementing a hosted service on top can create a 'comfort zone' for users hesitant migrating to IP.

In this report, we test OzVision's 4-HVR VSaaS hosted solution. Analog cameras are connected to their on-site encoder that can connect to a central station for video verification as well as stream video off-site for recording. Readers should carefully weigh the tradeoffs of their analog focused approach as it provides an opportunity for existing analog customers to migrate to VSaaS or verification but restricts ability to go 'all IP.'  

Recommendations

We recommend the OzVision 4-HVR hosted solution for deployments that require primarily video verification. With locked video settings configured for lower quality, OzVision sacrifices video quality relative to almost any DVR (even a low end one). A more expensive 2CH appliance/service can be considered for higher video quality. As such, we think users will have serious reservations using this as their primary recording solution.

Additionally, playback controls such as fast-forward, frame-by-frame or even a jog bar are not provided so detailed investigations could become tedious. Its apparent that the system is not designed for investigations that require more granular controls. 

For video verification alternatives, contrast to our test results of Videofied. For VSaaS, contrast to our analysis of 20+ VSaaS providers.

Key ********

Quality ******** - Customers requiring higher amounts of visual detail (e.g. face) will not be satisfied with the sacrifice of quality for bandwidth savings and smaller exported files. If this is more for video verification, this may be acceptable as re-sellers can provide central station services.

Setup - With existing analog cameras, the 4-HVR provides a simple setup; essentially, plug-n-play. A mom-n-pops shop or QSR owner may find the central station video verification and remote access to meet their surveillance needs. The easy setup and remote access will ease a SMB owner's anxiety migrating to IP.

Live ********** / ************** - For SMD / SOHO deployments that only require very 'basic' controls or utilizing the system for verification will find the Ozvision solution good enough. Without features such as fast-forward or a jog bar, we cannot recommend the system for those requiring detailed investigations. Less controls are more common with hosted solutions but we generally are provided an option to rewind.

Investigations - Color-coded blocks provide visual aid in the timeline as those with a red stripe indicate alarms triggered by devices (e.g. burglar alarm). Asynchronous playback is the only option and no granular controls are provided (fast forward). The exported files are compatible with COTS media players (WM, Quicktime, VLC, etc.) and provide the motion indicators for 3rd party viewers.
