You could go i5 but you need to configure the stream settings of each camera because it eats a lot of process even you are only using 6 cameras. If you are only using 6 then go for srn-1673s or 873s. They come with a built-in poe switch port at the back and can support full 2mp@ all channels

The NVR can support HIKVision cameras. Hikvision cams are reslly good and they are cheap nice quality too to be honest. There are Samsung cameras that comes cheap now a days but stripped down, they are expensive because the design typically is install and wait till it breaks in the next 6 years, we do have clients who are so satisfied because since the day we installed it we have never encountered trouble since. Get the Lite series but if you still find it expensive then go for HIKVision cameras again they will work since both manufacturers are serious with OnVIF compliance.

Even if it's ONVIF it doesn't mean that it supports ever function. Typically they only go with continuous recording or what the camera can give to the NVR. Did you try updating the camera firmware? Wireless isn't reliable as it looks better go wired like that guy said, I agree with him. You should have gone with a Samsung camera to get things on the same picture or a different camera manufacturer who is serious about compliance. Have you tried to manually add the camera instead of auto.search?

Hi, I want to hear from you people what are the advantages and disadvantages of a PoE supplied CCTV system? Many thanks!

Good point!

Seems legit Soundy, I had them installed 1:1 for power anyway you're right if the camera dies the view dies but not all of them gets off when you get 1:1 for power not all in a centralized manner. Well I guess I have to migrate to PoE for the up coming projects with regards to IP CCTV.

How about the lifespan of the wire or when the switch fails for some reason? the ports and stuff? Yeah I think centralized power and less wires is great but I guess lets just say security matters not installation. Because to be completely honest I don't have any problems with PoE switches at all trouble is when the switch fails or a port fails.

Can you please explain to me the true function of RoI and how it looks like? Does it work like this? I have a camera lets say 3MP then I focused it at 6 doors, now I want to record the 3rd door only without touching or adjusting the lens. Is that how RoI works? I'm kinda confused because I saw one that it's RoI actually just blurs the area that is not selected but records the whole area. Can you post pictures too?

I have a good question. Okay here is the set up we have Network PTZ cameras and we are going to connect them using fiber optic switches, we are going to use Cisco Smart Switches to be precise Catalyst Series 2900 with 2x SFP slots. Now my problem is the PTZ Protocol. Will the PTZ signal pass to the Cisco switch? Because someone informed me that Cisco and Pelco has something that they are sort of connected to them and the PTZ function might not work so I am concern about the protocol stuff. Can I control the PTZ function if I am going to use a Cisco switch? We are going to use Samsung Network PTZ cameras. Thank you again guys!

so in other words it will work in a Cisco Smart switch... I always rely on the product documentation because they will tell if it wont work on this kind of setup. I am really concern about PTZ working over fiber optic.....

Uhm we will us Cat6 cables since we are going to deploy them outdoor. Yeah I'm thinking of using switches but will use like may because the cameras are scattered all around the complex and they are in a perimeter. To add the cameras are PTZ... So I'm looking for alternatives like extenders but if I cannot find and I reach my deadline then no other choice we'll use switches and lots of them

Other than Veracity Network Extenders do you know any? Please do state the company and the website if any... Thank you!

Uhm Cat5/5e/6 yeah but it would be better if also there is a Ethernet over Coax extender. Patton does have one but I'm looking for one's that resells in my country. Because this is our answer to the 90m recommended limitation. I don't like wireless.

Awesome! How is that camera? Does it still work? It's too big and bulky, and why does it have an on/off switch? but yeah cool huh.

Define exactly how does your connection setup look like? Like are they on a switch, router, etc... All I can see if I understand your question correctly is that you are trying to connect your DVR to the internet and you want to access the DVR on a PC? At this point is it has something to do with port forwarding.

Alright here is the setup we have 12 PTZ IP cameras and we are going to connect them wirelessly on a Network Video Recorder. Now the farthest PTZ camera is estimated to be 250m. The AP and antennas that we are going to use can reach up to 500m with a power of 18dBi. Now I need your suggestion will the video transmission be smooth or we are going to have tons of problems with it? Like latency, interference, and the environment. The area is an open field. Any of you guys tried an setup a similar case. I asked this question because we are going to use D-Link Access Points and Antennas. I am proposing RadWin but they said it's too expensive. Thank you!

I see an ethernet extender that works like a repeater but more than of a repeater its like a switch type repeater. To be honest I am thinking of this one that you suggested a switch like repeater but I don't know the name. Now I'm learning much from you! According to the product documentation it can extend another 100m from the limit. What do you think if I use 3 of this linked together will that work? or for example I will group the locations like 3 cameras connected to a PoE Switch then an extender going to another PoE switch, I'm thinking that it will work. I will upload a related drawing for you and my new design with the extenders applied. By the way I also saw a Ethernet to Coax I was thinking of that may work too but I'm concern about the signal being transmitted incorrectly for data like I'll access the camera built-in utility not working over that kind of extender. What do you think? Oh by the way I didn't mention that the cameras that we're going to use are PTZ's....

Niel here are the things you need for you to access the device in your PC using the software(I'm sure that this one is compatible with the Smart Viewer and the Net-i viewer CMS software) or accessing it using your web-browser. ..... You need a Crossover ethernet cable to connect the PC and the DVR On your PC if it is an XP goto -Start>Contol Panel>Network Connections(if you are on classic view)>right-click on your Local Area Connection>Properties>Click Internet Protocol(TCP/IP)>choose Use the following address> Inside the IP Address box type:192.168.1.101 or any number from 1 to 254 except 100 because usually that is the default IP address of a Samsung DVR Under the Subnet Mask make sure that the number is set to 255.255.255.0 No need to fill the gateway and the DNS Address because you ain't going to access it to the internet or outside. To verify that you and the DVR are connected you need to ping the DVR and use the default IP Address. If everything is set then you go to your browser(e.g. IEx, Firefox) but I recommend IE. Type 192.168.1.100 and then the authentication screen will appear the username is admin and check the manual for the password I'm sure it's 11111111 or maybe 4321. Hope it helps!

We decided to go wired and wireless, all cameras with less than 90mtrs will be connected directly to the switch and the cams that are more than 90mtrs will be connected wireless. The only thing that I hate are the marketing people at the office they told me that I am a being too good for that setup... WTF?! I'm just doing my job... I really hate them can't they visualized that I'm a newbie and I'm just doing everything I can to provid a quick solution. I asked for professional help here at this forum and personally, and yet they say that I'm pretending to be good?! Why are there such kind of people? I asked questions and see comments and other responses I'm not being a know it all kind of person. I hate that dude in the office. I hate that instead of they advise you they even pull you down and give you negative remarks. To be completely honest I feel that those guys doesn't believe in my skills. But hell look at their side they can't even tell what CMS does a particular camera uses. Grrrrrrrrrr........ You know what dude I really appreciate your help. You're being kind and doing it in a nice approach.

Yes they are going to have there own wireless transmitter(AP) since they're IP Cameras. Well the compression method is H.264 or MPEG4 AVC then the framerate will be set to 15 or maybe 10 and the resolution is 702x240(Half or 2CIF). In my calculations the maximum throughput of each camera is 400kBps to 512kBps(if set to the highest settings that the camera can support. I can see each transfer rate to the NVR's utility). We are going to use Samsung NVR and Neti Ware cameras. Currently one of our wireless suppliers said that this setup might fail(and I'm also afraid of that especially when it rains) the supplier was proposing for Alvarion but I prefer RadWin but the cost is extremely high!!!! We are planning of using fiber optic cables but the PTZ cameras are scattered around the perimeter.

Alright, I've been bothered by this if this is really correct. About data transmission rates and the size being stored in the hard disk. Correct me if I'm wrong for example I have a camera that transfers 88 KBps so does it mean that the recorder is saving 88KB of data per second in the hard disk? Am I right? If no then how do I compute it?

did you open some ports in the router? as you can see you are behind a router and viewing a certain host in your network requires a port to be opened so that the services on that host can be accessed. A DVR behind a router requires port forwarding, usually you can find the settings in the DVR's user manual.

rory is right, it is possible but make sure your DVR is also capable. Try exploring the device first but I'm assuming that most DVR's today have that capability. Nice huh?!

Are you referring about remote viewing the PC-based system? If yes then I would rather suggest contacting your manufacturer about it. Visit their website.

A book, browsing this forum, and going to wikipedia would help you a lot. Welcome buddy!
