Vivotek has released their latest repositionable multi-imager camera, the MA9321-EHTV, a 20 MP model claiming "Supreme Night Visibility", "Optimal Image Quality in High Contrast Environments" and more.
We bought and tested this new model to see how it performs, examining:
How does it perform in full light (~300 lux), low light, ~(2 lux), and dark scenes (~0.01 lux)?
How flexible is imager positioning?
How does it compare in size to competitive multi-imagers?
How do H.265 and H.264 day and night bitrates compare?
How well does it integrate to third party VMSes (Avigilon, Exacq, Genetec, Milestone and NxWitness)?
I have more then 30 of these in various bids waiting for approval. Absolutely love them and the smaller footprint. Vivotek has great multi sensor cameras and solid integrations. They obviously know how to partner very well with VMS manufacturers.
You don't have to buy any appliance for 3rd party support with Avigilon. They generally integrate fairly well, at least with single-imager cameras. Multi-imagers are less supported, but still generally work.
That being said, they do not list any integrations with Vivotek on their supported devices, nor does Vivotek list them as a VMS partner, though they list Exacq, Genetec, Milestone, and Network Optix. So it's not so likely that this compatibility will be addressed.
I never said they make all their cameras. If I was not clear about that then I can understand the misinterpretation and that would be my fault for not being clear. If that is the case then I apologize.
I believe the $15k appliance you are referring to is the unit that adds Avigilon analytics to somewhere around 60 third party cameras. You are badly misinformed if you think it takes a $15k device to record third party cameras.
The camera is listed on ONVIF's website as Profile S conformant.
In our testing, though, while Profile S has typically guaranteed that you'll get proper streaming from a single channel device, multi-channel devices are hit or miss. We've seen issues with other VMSes using ONVIF, as well. We will ask ONVIF for comment on this issue, actually, because multi-imager is prevalent enough that it's an issue.
It does not stitch. Stitching is typically only used in fixed multi-imager models (180° or 360°). Because the imagers of this and other repositionable models may be moved, and there is likely to be gaps and overlap in where cameras are positioned, they don't stitch.
Genetec and Vivotek have pointed out that the MA9321-EHTV should use only one license for all four channels, but in our testing it used four. This may be due to using a pre-release Security Center 5.8 license. We are updating to production licensing today and will update with our findings.
Added a section on VMD performance. The Vivotek MA9321-EHTV does not include intrusion detection, we tested the performance of VMD and the camera alerted on the simplest of false alarm sources in the scene, such as blinking lights from switch ports.
