Thank you for your kind reply, I agree with you that buying a didicated system, which does itself the work, which has a camera disigned for that purpuse, etc, it's alwyas the best choice in terms of reliability. But the cost does also have impact here, installing 2 of those VTOs in a different place (right away the face of an adult), and rebuilding the decorative wall make the client think twice, and maybe wait for some seconds than pay all those amount of money. This is why I'm evaluating, with you plus and minus.
It's a villa with 2 entries and one monitor inside, also it needs another VTH that should ring first in queue.
The house has already two VTO-6100 installed and working, which suggest to evaluate the use of an AI NVR, as you said.
I've contacted Dahua but ad you perfectly describe, they don't support the way they have to, and their software often are incomplete, feature are missing and so on. So, the best way is to share experiences between us and be sure before buy anything with them.
As I told, before destroy and change everything, better to know what I can do with existent staff.
Thinking to leave actual VTOs, enhance the light sytem during night, I think I can face this:
Positive factors
- cost
- quick time implementation
- using an NVR leaves me the chance to load faces remotely and have them working on both VTOs, saving client to add/edit himself on VTOs. Seams SmartPSS lite can help with NVR and manage face database, but I?m not sure it works wth new VTO too
Negative factors:
- there is no 3D recogniction, a photo will be enough to fake the recognition
- poor quality of cameras, probably lot of time is required
- nothing is spoken when the door is opened (or there is a way to force VTO say somethng?)
- I have to use one spare pair of cat5e cable to bring the contact for opening the door from the NVR alarm out (but I've found some support with Dahua API on Node Red, so I can use that to open the lock byt network)
I still wonder to know if I can use SmartPSS to push the face profile on both new VTOs VTO6531H , or I should work manually with the VTO display, and if I have to reply the same work on the other VTO.
What VTO6531H needs to be configured? If only DSS is able, do I need to pay also for that?
WHere VTO6531H saves its job? Do I need to buy a Dahua NVR tha can support it? And does this NVR dincronize both VTOs?
Thanks for clearing!
