have you used a port check tool to see if the port is open:- canyouseeme.org or similar.

welcome to the forum. theres plenty here to increase your knowledge- i'm 20+ years in CCTV and still learning every day.

nice example of port forwarding showing diagram and a router configuration for forwarding the ports. http://www.noip.com/support/knowledgebase/multiple-servers-behind-a-nat-router/

Dahua NVR Losing Network Connection Every Second
jazzar replied to kmax1940's topic in Computers/Networking
do you have enough bandwidth available on the school network- maybe the cameras are pushing it over its limit ? could you have a duplicate IP address assigned to the NVR ? -
you did well- glad I could help- good luck with it.
-
any firewalls maybe blocking traffic ? try running an open port checker to see if the 9222 and 37778 ports are open. try swapping the port settings around for dvr1 and 2 and see if 9221 is reached on the other DVR. Last suggestion run wireshark and see if you can capture and analyse where its going wrong.

GE/ Kalatel DVMRE Power Supply Replacement
jazzar replied to jclick's topic in Digital Video Recorders
this any good- quick google :- http://www.amazon.com/Adapter-KALATEL-DVMRE-4CS-7-Supply-Charger/dp/B00AI1BG7M -
ok well done. under the details tab it should provide some more details, select details tab then select the drop down box and select hardware - this should give you a vid /pid code- this is the code that identifies the vendor-manufacturer- again google for this info there should be a vendor id lookup page or similar. once you get there hopefully you can get drivers from the manufacturers web page- but like others say maybe they wont be updated to suit windows 8.

anyone tried this cheeky little number- and its cheap as chips. http://www.aliexpress.com/item/PK66B-Video-monitor-tester-Hunt-features-Emergency-Power-Supply-12V-1A-Lithium-battery/1385880989.html

Problem Panasonic CW960 with command from keyboard PTZ
jazzar replied to R1966's topic in Video Transmission/Control Devices
don't see anywhere in the manual for the camera that says PELCO protocol can be set on this camera. looks like a mismatch on your set up- would be my best guess. -
linking Status Failed on Hikvision NVR Using 8 Port Switch
jazzar replied to malford's topic in IP/Megapixel Cameras and Software Solutions
ok so break it down to basics- what is the ip address of the NVR and the DVR, are they on the same network range ? first step can you ping the NVR direct from your laptop without the router being connected, then try connecting the router and see if you can still ping it. -
if you plug it into the pc and boot the pc it should detect the device. under computer properties- device manager you should see an unknown device. select the details of this device should give you some some code /instance details which you can then google and hopefully find exactly what it is so you can then get the required drivers. try googling something similar to find unknown device.

smallest router for 4 channel portable NVR
jazzar replied to HeadsUp's topic in General Digital Discussion
searched on google for small form factor router - came up with this:- http://mil-embedded.com/news/rugged-small-form-factor-router-running-cisco-ios-released-by-x-es/ looks expensive and CISCO = EXPENSIVE. What about the effects of vehicle motion if you intend using while vehicle moving- you would be better off with a SSD hard drive. -
looks like you have a common ground wire in each of the pairs thus any one of them being connected gives you a return path to the 0v of the supply.
-
once you change and save the settings try rebooting the unit - it may need a reboot to take on board the changes.
-
have you checked if it needs to be allowed for remote control/ for logging in.

Help with DVR Remote Viewing Via Internet
jazzar replied to kiqo4284's topic in Computers/Networking
have you checked if firewall is blocking traffic. or use checkmyport.com and see if your DVR ports are being seen from the outside world. -
veracity do a portable poe supply which allows you to power camera locally and set up with a laptop etc., they may have a solution including a test monitor kit for IP. maybe worth a phone call.

looking at dvr spec says approx. 20w without hard drives or dvd, I would allow 50 watts for your calculation. so total load = 50 + (10 x 5 for cameras)= 100w. contact cyber power to get the run time of the product with this value should be around 200 minutes.

One UTP vs two UTP per video balun question.
jazzar replied to POOLEYR's topic in General Digital Discussion
1 pair should be used. the reason is that one pair can have different number of twists than a second pair. the signal is measured as the difference (voltage) across the two wires- this is good because any noise present in the cable run should appear on both wires and effectively cancels itself out resulting in only the original signal being processed. different pairs with different twist ratio could allow different noise to be present and NOT completely cancel itself out. looks like installer is getting confused using two pairs. using two pairs means more cross sectional area for signal to travel down or using power allows more current to flow, increasing the cross sectional area means less resistance- so doubling up would effectively half the resistance of the circuit. -
Break it down a step at a time. using the cmd command on your laptop, with the laptop connected to one of the DVR's try using the "ping" command and see if you get a reply from the dvr- if your not sure what I mean just google "ping command" and you will get a youtube video about it. if you don't get a ping reply then you will never get a connection, once you can ping it then you can see if you can get the web browser to connect by putting the ip address of the dvr into the address bar at the top of the web browser page.. once you can connect via the web browser you can then check port forwarding is set up on the router for remote access. google any of the above for more info.

How do I hard wire from DVR to laptop?
jazzar replied to Leftyguitars's topic in General Digital Discussion
you should be able to connect your laptop direct to the dvr with a network cable, you will need to set the laptop ip address to the same range as the dvr and set the subnet to 255.255.255.0 so if your dvr is set as 192.168.0.10 with a subnet mask of 255.255.255.0 then you set your laptop up as 192.168.0.??? with a mask of 255.255.255.0 and you should be able to connect via the web browser or software for dvr viewing. ??? can be 1 to 254 but not the same as your DVR google info on how to set your laptop to a static ip address if you don't know how, its slightly different for the different versions of windows- assuming its a windows laptop. -
What Cat cable, connectors, etc should I use?
jazzar replied to Joeinamillion's topic in General Digital Discussion
what is your application ? a one if home installation or continuous installations ? see:- http://en.wikipedia.org/wiki/Twisted_pair for info on UTP, STP only matched up for 1gb speeds so utp should probably do for you and assuming your cables are not running in a heavy industrial plant with lots of electrical noise thus the connectors wont need to be shielded then. If running outdoor cable it should have suitable uv resistance and handle the outdoor temperatures, if going underground it should be of a duct grade quality- impervious to water. The tools all look ok - haven't seen the last one before. the standard should be kept throughout the full installation ie all cat5 kit or all cat 6. one cat5 item in a cat6 install results in the system being classed as cat5, so cables and boxes and connectors should all be of the same category throughout. size of cable box -500ft or 1000ft = totally up to you. from what I have read some cheaper cable instead of being copper is only tin with copper plating = less performance=more trouble. if you use shielded cable and don't use shielded connectors - whats the point- you have failed to ground the shield to equipment which is the whole reason for using the shield in the first place. I would run the cable straight into the dvr, I less joint to affect performance but either or, the dvr should be in a static place and not be getting moved around a lot thus not putting much pressure on the network cable ends going into the DVR. cable boots are a nice finish and also support the cable. good luck- there are also some handy cable testers which can do a basic continuity check by fitting a dongle at one end of the cable and the tester at the other end and leds or a display will show if there are broken or crossed wires- pretty cheap on ebay, test your cables before connecting anything up- good practice. plenty of info on google.
