@codepatcher how have you got on with your gear mate? Anything delivered and tested yet? Or still waiting on delivery?

NVR was delivered ok...it was shipped via DHL express for free, got in in 6 days, picked up a 1TB purple drive on amazon for £41 and installed it. Still waiting on cams, its two weeks now since they were shipped!! Tracking info says they were handed to airline, I'm beginning to think they're on a boat.... and that boat sank.

@codepatcher any recommendations from the list. Will order one to test.

Thanks

@vaf888 I've just Pm'd you mate.

@leemoo and anyone else that is following this thread. My 3 cheapo (£21) IP POE cams arrived Monday. Packaging not great, 3 cams each in their own small box. All 3 boxes then wrapped together in some bubble wrap with some tape to keep it all together. A couple of the boxes were dented and crushed but cams themselves not damaged. I hooked them up to the Dahua NVR that arrived a month earlier. As the cams are the same they all have the same default IP address, so I had to attach each cam one at a time and change the IP of before connecting the next one to the NVR. Almost immediately pictures started to come through, but I noticed that the bit stream would start to drop on each at the same time and then would all disconnect and would connect again and all disconnect a couple of minutes later... and the cycle would repeat. Unsure if this was the NVR or the cams I spent the next day trouble shooting.

The pattern would be the same for each cam even then they were connected at different time, as if they were on their own clock for a cycle of connect and disconnect as if the cam was not being kept alive and it would time out. But after playing about with some settings and lowering the bit stream a bit I found the connection became much more stable. I'm not finished tweaking, but just be lowering the Res to 720P and capping the bit stream I am able to keep cams connected for 40 mins without any cams offline alerts. I'm not done tweeking the settings, as there are other settings within the cam not accessible from the NVR. I pretty sure NVR is up to the job and its just a matter of finding settings for the cams at which they can run to be stable, I will have more clues when my main 4MP cam arrives to see how it performs. (learning the hard way)

@codepatcher keep us updated mate. Certainly interested in how you get on and am sure others will be....even if they don't know it yet

Google HiWatch, Apparently made by Hikvision but a bit cheaper

@codepatcher alright mate seen a post earlier about POE and reminded me of this post. Did you get any further with this? How was the kit you bought.....did it work out for you?

Hi mate,

Dahua NVR and 4MP cam spot on, the cheaper 1080P cams are a bit temperamental, record fine, but when in motion detect mode its hit and miss, sometimes they just fail to detect motion. To the point where I just leave them record on a set schedule and even at that they are only stable at low bit rates. In time, I will likely dump these and pick up 3 more of the dahua cams. Really impressed with Dahua cam for the money, the the smart video analytics and trip wire features help reduce false alarm detection, works flawlessly with the NVR. Also Dahua have a nice app for the phone and there is also the option of using their smart PPS software to manage both the NVR and the Cam. Playback and features via PPS much better than logging directly into the NVR IMHO.

but when in motion detect mode its hit and miss, sometimes they just fail to detect motion. To the point where I just leave them record on a set schedule and even at that they are only stable at low bit rates.

Is there a sensitivity setting on your NVR for the motion detection on the cameras something like low, medium, high? Or does that not matter do you think its down to the actual cameras?

There is a sensitivity setting. It works fine on medium, picking up little things like plants blowing in wind, but then would fail pick up anything, even a person walking it front of it on a clear day. Then they would walk by again in a few minutes and it would detect them. Most of the settings for the cheap cams can't be accessed via dahua NVR, so you have to login to the web GUI of the cam, which is nuisance when cam is connected to NVR POE ports, which is more or less a separate network. I am thinking of getting a separate POE switch and putting the cheap cams on the network and then from their let NVR pick them up, rather than connected directly POE ports on NVR. I might get better performance from them then and easier to will be much easier tweak settings like that, I may even go as far as changing the mac addresses because to rule out any device conflicts.

There is a setting on mine were if the motion has been activated then it will wait so long before activating again or could be something to do with the FPS. Can't remember which off the top of my head but you can change these.
Just wondering if something like a plant is blowing and then that activates the motion detection and then may someone walks past but because it has already activated it won't run again for a period of time.

Waiting before coming active again. I will check that out mate. Already played about with FPS, but will revisit it. I think it more than likely is something to do with the config or how it is configured when working with NVR. Will look into that but going to make it easier by first getting a POE switch first. Saves me doing a hack on a manual config of IP address on PC and then connecting PC to POE ports on NVR to access GUI for chepo cams.. alot of the advanced setting for the cams cant be acced via the NVR.

Keep us posted how you get on and any new kit you get

Will update soon mate, buying this week

@codepatcher how did you get on mate? Did you buy anymore cameras?
Starting to think of looking myself a replacing my old system.
Hows your NVR (Hikvision NVR 8 Ch POE DS-7608NI-E2/8P/A) system been?

@leemoo Hi Mate... its actually 8CH POE Dahua NVR4108-8P-4KS2 NVR I got. Its humming away fine 24/7 with A dahua IPC-HDW4431C-A 4K with built in mic as main cam. I find simultaneous playback is better via Dahua's smartPPS software rather than locally via the NVR. Not sure why that is, I think Dahua putting alot of effort into their PPS software which built to manage multiple commercial grade Dahua NVRs and cams. As for the other 3 cams... they work away fine on continuous record.. but I haven't got around to replacing them yet. They do the job.. but for the extra 20 odd USD the Dahua cam just out classes these cheap cams in every way.

Another thing about the cheap $21 cams... I'm getting IR reflection of the visor as the black sticker on the inside of visor has come off. I coloured the visor with a back marker but doesn't help much. The Dahua NVR and Dahua cam get a thumbs up from me for price and quality. Wish I had sent the extra $75 get all Dahua cams.

Thanks for the update mate

I'm sure you'll get around to updating the cams....start saving your pennies

If you get more of them cams will you be able to use the mic on each of them or just the one?

Will be able to use mic on all of them mate. The audio from the built in mic is encoded into the video stream. So whatever each camera can hear that will be what is encoded into the video stream for that channel. With regard to playback.. as you know you can view multi channels at once on playback, but you are limited to only hearing audio from one cam at a time. So if I were looking at channels 1 and 2 simultaneously I can see video for both, but would only be able hear audio from one or the other, not both together. You simply click on the channel you want to hear audio from.

Found that same system you have on the bay with 6 of the same cameras and a 2TB drive for £415.14.

That sounds like a cracking deal mate. 6 cams and 2Tb drive included. Make sure MVR has 8 POE ports, there is NVR 8 Channel but only has 4POE ports, other cams can be added via network or switch.

The cam that I actually got was the V2. IPC-HDW4431C-A-V2, not sure what the difference is between the IPC-HDW4431C-A and IPC-HDW4431C-A-V2. Multi Language support and better night vision.. thats all I think it is.

I also picked up this wall bracket too, to mount it from when I ordered.

if you find any of the cams on their own on ebay can you send me the link... I might take a shot at them is price is right.
