Hello everyone. Im planning to install a dahua VTO6521K to my building and my question is: is it ok to power it with 12vdc as needed and add it to poe switch for the network? To work with all vth to the same network? I will have a problem with vdc and poe at the same time?
Thank you
Hi everyone.
I bought a dahua nvr NVR4208-EI. I configured like always and i use time zone e. Europe. But when i try to add the device under account on dmss when i choose my time zone it says failed to save configuration. First time happening to me this. I dont use dst or ntp.
Any ideas?
Dahua since february is working (making test) with the app for alarms. There will be a time in the year that you can use the alarm with the new nvrs and softwares to work all together. Dahua name it AirShield. Thats why we all have these problems.
The power supply was already install from before. The client want to change the old doorphone with vto and vth so i didnt replace the power suplly. Yes it is 12vac power supply. I dont know the model of the door lock
I think the relay from all dahua vtos is a dry contact. Also the most door locks in my country work with ac and not with dc. And another important think is that is the only client complain about this. Why the relay of the vto allows the current to pass? It is a NO lock
Hi everyone
I face this problem and i need some help.
I install a dahua vto to a house cable weeks ago. The system worked perfect.
My connection was with transforner ac-ac. Cable from the transformer to electrick lock. Cable from transformer to COM on the VTO and from VTO to electrick lock via...
Yes i know that. I will draw my line after rotate the camerA. But the warm light and alarm light will be up after this not under right? I hope this give me a good image
Hi can check the above pictrure from dahua camera 3.6 lens. How you face this kind of area? This close distance between walls. If i choose a 6mm lens i will lose area from down the camera? Any other solution?
