Recording CCTV on dvr via ethernet....

Recommended Posts

First i would thanks the creators of this forum for providing such an excellent platform for knowledge sharing and resources which has helped many a noob's like me in setting up their home surveillance system...

 

Now i have installed 6 IP cameras in my home and all are wireless connected to my router (linksys wrt610n) for recording the same onto my computer.However i seem to have overestimated the router's capacity for transferring all the footage from all IP cameras to my computer and hence the same hasn't worked out as expected.Hence now i wish to buy a DVR (placing it near the router) and use the same for recording.Now as i do not wish to extend wires from all the cameras to the DVR, i wish to know that can i connect the router(which still captures the footage of wireless cameras) and transmit to the DVR over ethernet via lan cable and record the same?? Will the DVR record the footage from all the cameras(wirelessly connected to router) over ethernet via LAN cable or will it record the only one of which IP address which is entered??

 

In short......is this possible????

 

IP CAMERAS-----(wireless connection to router)-->ROUTER----(LAN CABLE)--->DVR (for recording footage from all cameras)

no, this is not possible. a dvr is designed to record *analog* cameras connected directly to it.

 

what you're looking for an in nvr (network video recorder). the catch is, you need one that supports your cameras specifically. what cameras do you have?

 

the other problem is that the cameras are probably taking up all the wireless bandwidth by themselves. changing your recorder won't help that. connecting your computer directly to the router rather than by wireless may help, but ultimately, your best bet is hard-wiring your cameras to a switch.

How would the DVR do any better than your computer at resolving what your observed to be a network bandwidth problem?

Thanks for ur reply....

Please correct me if i am wrong but what u mean is that no DVR can record from any input source from the Ethernet via lan cable???

I have 6 WANSVIEW NCB541W cameras.

Well initially my plan was to wirelessly record on my PC (router being centrally placed in the house and the PC being in another room). However i overestimated the routers wireless transfer capacity and now can barely get footage from 3 cameras and that too at a paltry 4-5 fps.So yes if nothing else works hard-wiring may be the last option but which will be very cumbersome and hence i require a solution where i can place a recording equipment (like DVR) near the router and connect it manually and record.

Thanks for ur reply...

 

As my router is centrally placed (to get the wifi signals from all cameras placed at different corners of house) and the PC being in another room, i was looking for a solution where i could connect the router to a DVR(or any such recording equipment). So yes a PC/Laptop would be an obvious solution but will have to move the same near to router....and that would be the last option if nothing else works....

well, a "hybrid" can. which is essentially a dvr/nvr combo unit. on a standard dvr though, the ethernet port is meant for remote client access, not for recording.

your basic "toy" cameras. few if any hybrid dvrs or nvrs would directly support them. they *may* work with an onvif-compliant recorder, or with a higher-end recorder that allows you to specify a custom url for the h.264 stream. generally these types of cameras are designed to work with their own software and nothing else.

consider that even under ideal conditions, your wifi connections only realistically give you half the advertised speed... and then the connection to the recorder (pc) has to handle the combined bandwidth of all the cameras. and you will lose signal quality as distance and obstacles (walls) come between the router and pc. camera feeds also typically just send a steady output stream with no communication back from the recorder to tell it whether the recorder is receiving properly. so if you get dropped frames or a spotty signal, the dvr can't tell the camera to resend the data; the camera just keeps sending it and the recorder has to keep up.

what's so hard about taking your recording pc and moving it beside the router? if you can do it with a separate dvr, why not with a pc recorder?

 

keep in mind you really shouldn't be using your regular desktop pc as a security recorder - you should always have a dedicated machine for this purpose. doing other work on the computer will take up bandwidth to that machine, and other disk i/o that can also affect the camera feeds writing to disk. it's just not a good idea. realistically, most "standalone" dvrs/hybrid dvrs/nvrs these days are just small-scale pcs running on minimal hardware using an embedded version of linux or other linux-type os.

I think the wansview cameras come with some software that you can install onto a pc to record video with, also, the bigger issue like mentioned before is bandwidth, there are a few things you can do to lower the bandwidth coming out of the cameras that should be a big aid in getting the streams to your computer. I don't know if Wansview uses a fixed bit rate stream or variable bit rate with a cap. I looked at a config page of a Wansview, and you should be able to turn the stream rate down to say 1024k or even 512k which would free up some bandwidth on your wireless network.

thanks a lot for ur detailed reply...will try and shift the PC if possible.....or else wired connection might just be the way to go i guess.........

Thanks a lot for ur effort.....yes i did try and reduce the bitrate but didn't seem to have much impact...will probably try hard wiring route now.....thanks a lot again
