Guys, My client has returned one ptz to me as he said the ptz doesnt work anymore and need to claim the warranty. But the ptz is out of warranty. Anyway, I had diagnosed for the whole afternoon and why found out something is wrong with the PTZ and it is weird as well. Here is what is happening to the ptz. I unscrewed and took out the head of the unit and then place it on the table, miracle happened when I turn on the power switch. It has no problem and its works as what it should be, pan, tilt, zoom, scan and so on. BUT..... as soon as I place it back into the cover, it does not work anymore. Anyone know why and can you please help me ?

I will go back to my office and have a look at the camera and nvr model. I will take some picture of them and post it here. Thank you so much for your reply and I am looking forward to hear from you again.

Sorry if someone has been posted this question before. I am new to IP PTZ camera and I would like to find out how to connect 2 IP PTZ camera into 1 NVR? It will be running 1 cat5 for the video, a power adaptor for the power and extra cat5 cable standby. your help will be appreciated and thanks

Hi Everyone, I would like to find out what could be the problem to made my NVR does not shut down after you selected shut down option. Anyone is having this shut down problem? Do i need to update the firmware? Thanks

Guys, I have a few question about hikvision camera and the nvr. 1. Chinese Version camera compatible with English NVR? If it is compatible, does it show English on the camera display or Chinese? 2. Easy to convert from Chinese version to English? 3. For this nvr model DS-7604N-SHT/P, does it support 4 3mp camera at 2046x1536? Or just 1080? My friend told me they only support 1x3mp at 2046x1536, the camera output resolution will be capped at 1080 if 4x3mp are connected. In order to output 4x3mp at 2046x1536, I will have to get the 8ch nvr .Is that true? Thank you everyone for taking your time to read and help me out. I appreciated a lot. Cheers

Alright.. It means that the nvr doesn't support 4ch 3mp at full resolution. Only one is allowed.. Thank you so much.

Thank you for your replied. What I meant for the last question is.. Does the 4ch NVR able to output full 3mp full resolution for 4 3mp?

Hi Everyone, I'm looking for some advices that which camera suitable for night club use? Color? or B&W ? Thanks
