Hi Best thing to do is to have a strong username and password on all your devices, are you connecting to your cams remotely? meaning when your away from the house? and how? Via dyndns,p2p or puplic ip,? the Samsung smart cams must have a UPNP (Universal Plug and Play) function on them that configures your router for you, if you don't want a device to do that you can disable your UPNP setting in your router and just do the configuration manually hope this helps Regards

According to Dahua it is plug and play, the cams connect directly to the NVR, I am receiving mine next week and will confirm, will let you know Regards

Hi here is today's one time password 597840 please PM me if you need another password, this will be used for the admin password Regards

Hi Here is today's password 598240 you can use this as on your admin account it should work, the password only lasts for a day so you can PM me if you need it for another day Regards

Hi It can be your PSU for your DVR not pushing enough amps to power the DVR and HDD, it can also be a short/fault on your HDD causing the DVR not to boot up as most DVR's do a self test before booting up, if there is a problem it wont boot up, try testing or replacing the HDD, also try another PSU with same voltage and with same or higher ampage if you replace the HDD the DVR should format it itself to the correct setting hope this helps Regards

Hi Did your brother-in-law have a app or software running on one of his devices (ie: PC,Laptop,Tablet) that connects to the DVR? are the parameters change to the correct setting namely the Ip address, username and password, you can also check your firewall setting on your router, first establish connectivity on that Ip address by doing a PING test then check that the username and password is correct, the DVR will lock after 3 failed login attempts , just restart the DVR and try again, getting a invalid password error has nothing to do with your network connectivity hope this helps Regards

Hi It can be the HDD thats faulty or the PSU for the DVR not pushing enough amps, you can test your HDD with HD tune pro or try using another PSU with same or higher ampage regards

Hi All I have a customer with AHD cams, the fluorescent lights is causing interference (horizontal lines ) , Iv checked on the OSD and there is no setting to change the cam between 50HZ or 60HZ was wondering if any one had any other solution, Iv read up that changing the exposure settings might help (see you tube video:https://www.youtube.com/watch?v=4Go3ksjkoKU ) however haven't got the equipment to test. thanks in advance

HI Is it a Dahua IP PTZ camera, if so you can change the camera number with the dip switches send me the model number then can get you the dip switch settings

Hi You can try and log into the camera using the ip address of the camera via a browser and check the settings there, Regards

go to www.canyouseeme.org and check if that port is forwarding, are you using the local static address or a public static address?

What Hard drive you have in the DVR? I had the same problem, the customer was using a standard HDD then we changed it with a SV drive and it fixed the problem also check what your prerecord is set to, the default is 4

Hi What is your recording set to? Is the picture blurry or you just cant make out face? your lens could be out of focus you will just need to re-focus it or if you just cant make out face try changing the lens, at 15metres a 8mm or 12mm will work depending on what all you wanna see

You must use eg: http://192.168.1.20:90 the :90 must be the new port you change to

Hi you can check SECURAME's post under this thread viewtopic.php?f=12&t=46191 should help you with your issue

Hi Wizz First network all the devices together and make sure there is communication, the light that's not indicating on the non-poe port means there is no communication or the led is broken most likely the cable or connector,once you have communication you will need to configure your remote setup: What camera have you got? if the cam has p2p or build in DYNDNS should be easy to setup, otherwise you will have to register a DYN and do the port forwarding on the router

Hi All you have to do is change your http or server port on the other dvr, how are you connecting to the dvr? via cms software or browser? eg if your one dvrs server/utp port is 37777 make the other one 37779 and when connecting via you static or dyn use the corresponding port

Hi Please see links https://www.dropbox.com/s/z66u7irn2fh1s9o/MOBILE%20DVR%20SD%203G.pdf?dl=0 https://www.dropbox.com/s/xu696zvhvgl0a2w/Mobile%20dvr%20with%20hdd.pdf?dl=0 We have a Mobile fleet solution with gps/3/4g/wifi connectivity all works to a central server,we have HARD Drive and SD card versions, you can remote view via pc pr cellphone, hope this is what you are looking for unfortunately our AHD version is not out yet will be around August we currently have it in D1 can take up to 1200tvl cams however our car cams are only 540tvl but works great for mobile solutions, PM me if you need more info or even a demo

Are the Cams Dahua or other brand?, You will only be able to change the cams name if they are also Dahua cameras,under ONVIF protocol you don't get all the communications to the cameras like you would with the same brand cams, also if your cam is not ONVIF compliant it wont connect to the Dahua NVR, you could always check to see if there is a ONVIF firmware upgrade for that camera.

SunnyKim Well we only sell Siamese ( we call Poweraxial ), and cat5, it works out almost the same if you compare the price of BNC (R2.49) and the price of a Balun (R22.00) eg: 100m powerax with 2x BNC works out R408,79 and 100m cat5 with 2x balun is R422,94 that's of-course in South Africa don't know what your pricing is, However you can put 2 cameras on one length CAT5 so will work out in the end Cheaper, But I would still recommend Powerax all the time,less to no interference, I should mention we only use solid copper core high quality cables.

What was the distance on your longest run? Iv tested HDCVI on 300m cat5 e no issues, ground loop isolators also work on HDCVI, was using PV-207 balun http://lsvt.com.cn/pro_view.asp?Shop_ID=1209 works extremely well, the quality of your cat5 is very important and can cause the interference.
