Going back to my original question I am guessing that I should be using a 4K HDMI cable to get this to work.

No. Did you read the responses? You DO NOT NEED a 4k monitor...

I read the link: Costco /QSee 16 Channel System,

http://www.costco.com/Q-See-16-Channel- ... 13199.html

 

Found out the NVR claims 4MP camera recorded at 20FPS rate per channel...

It claims to handle 16 Ch.

Can anyone confirm that the DVR can really de-compress and play back 8 Ch or 16 Ch of 4 MP recorded each at 20 FPS, simultaneously on a monitor?

Its DOES handle 4mp. It DOES handle 20fps per camera. Why do you use the word "claim" as if alleging that this is a false claim?

There is no reason to playback 8ch of 4mp video, because the monitor will NOT be displaying that if you have 8 cameras on a 1080p monitor. How many times do you need to be reminded of this? Why do you keep asking for this useless function as if not having it is a bad thing? At least the user can view full 4mp if they want to in full screen and zoom in on the important detail. Do you have a better solution? other than recording in low res 960h which gives you low res images that cannot be effectively zoomed in on and cannot provide a 4mp image either? As usual you make no sense.

That NVR can playback up to 4 ch at full res..an 16 using the substream..which will still be better quality than junk 960h and the user has the OPTION to then select ANY of the cameras and watch up to 4 in full res at a time...but again, it doesnt matter on a 1080p monitor if you are watching a matrix because the monitor itself is NOT capable of displaying more than 1 camera in 1080p...Please please learn about this technology before providing incorrect advice to users on this forum!!! Enough is enough.

Tell us why we need FULL 4mp res x 16 cameras on a 1080p monitor??? it makes ZERO sense.

If the users plays back the substream and needs further detail, they can bring up a single camera in full screen then zoom in.

Hi all, I'm looking for newbie recommendations for a new home IP poe system. I currently have a q-see 960h system. I was considering this from costco:

 

http://www.costco.com/Q-See-16-Channel-HD-IP-NVR-with-3TB-HDD,-8-4MP-Cameras-with-100-ft.-Night-Vision.product.100213199.html

 

but its pricey and limited (only records 1080p), and I thought I'd look into buying individual components so that I could build on it as I go along and perhaps save some money (or get better components for the money), and that's how I found your forum.

 

I would like to buy:

8-16 channel nvr, atleast 8 channels poe

8 4-5mp cameras, good night vision

 

I'm not anticipating being a power user and just plan to record around the exterior of the house, and want to make sure I have a reliable system that can adequately record up to 8 hd cameras (or more, if affordable.)

 

Any recommendations/advice would be appreciated! I see lots of hikvision dvrs on ebay as well as hikvision and dahua cameras.

 

TIA.

The costco system is a rebranded dahua..it will record in 4mp mode, note sure why you think it will only record 1080p..

hello,

i started out looking on e-bay for a cctv system,after i had my car hit,i found one and had it at £149,99,but changed my mind with it being wired, then i bumped into ptz cameras and thought id look for a good one, i started to get confused with the info of what i needed, so thats why ive joined your foram for advice, im not looking to spend ££££ but ive made a few point of what i think i might need

 

1)DvR/Network recorder ?

2)8-channel

3)Ptz outdoor cameras

4)1tb hard drive

5)960h

6)wireless(must)

7)720/1080 Tvl ?

controller

 

can anyone pls help me out, i would probley use e-bay to buy the system

Its 2015..do NOT buy a 960h system. At the minimum it should be 720p (which is double 960h) or 1080p....start doing more research...forget about wireless...if you buy crap before knowing what you are looking at your will be sorely disappointed...

Still the same whether its a powered mic or not. That line in functions the same.

No it does not. The hikvision cameras support, powered and non powered mics, you need to set the interface accordingly.

1) Should i be concerned with type of cable for cameras f the length of run is under 100 feet?

 

2) Does it matter RG59 or RG6?

 

3) What brand compression BNC connector do i use?

 

4) Any input to what i need to watch for?

If you are running new cable for a new install use ethernet cat5e/6..you are best off with an ip system on a new install. If you insist on analog, look at TVI/CVI systems that are HD and simply use Baluns at the ends. Do NOT buy cheap cable on ebay etc...make sure its solid cable and COPPER not copper clad aluminium (CCA) which is junk.

That is kind of how I was thinking.

So if I digitally zoom into 1/4 of the screen of a file that was actually recorded at 2560X1440 (3.6 million pixels), would the video I am viewing have roughly 1 million pixels rather then zooming into 1/4 of the screen of a video file that was recorded at 1920X1080 (2 million pixels) giving me a video image with 500,000 pixels. It looks like I should have twice the resolution.

Note that 4mp is not twice as clear as 1080p, that all depends on the actual pixel density. The point is that you can benefit from higher res despite using a lower res monitor.

Can the demo video of 4K(UHD) camera clearly identify a face or license plate? Was it impossible to carry out such things before 4K camera was invented?.

Answer is Nope, for both.

You may be just wasting money for more HDD and new price tag of a new product. You will have less number frames per second. You will have many small problems of buffering or time lagging when the camera is added to your NVR to which many other cameras already connected. You will need a new expanded NVR that can decode and play back videos.

The camera for broadcasting is more expensive than cctv camera. 4K video can be enjoyed on 4K monitor. If you need one, buy 4K (8MP-UHD) cameras dropping 4MP camera? Why? Those guys who are now promoting 4MP will be talking badly about 4MP cameras when they start to promote 5MP/6MP/and 8MP -UHD cameras, soon.

Your response is off topic. The op is in regards to any resolution higher than 1080 viewed on a 1080p monitor. The 4k camera CAN easily identify a plate, why do you say no? even a 1080p camera can identify a plate, the difference is that the 4k camera (assuming the same field of view) can identify a plate from MUCH further away. I urge you to buy and test high resolution cameras before giving this nonsense advice.

There are no buffering problems on high resoluon cameras - NONE. Not sure where you are getting that info from. 15fps is way more than you need. You DO NOT need a 4k monitor to benefit from 4K cameras as can be clearly seen in the ZOOMED in image in the youtube video.

Hi all

Could anyone tell me if there is any advantage to having a 4MP camera connected to a Dahua 4K NVR, recording at 2560X1440 if I am only using a 1080P monitor for playback?

It would seem to me that this setup would allow me to get a higher resolution when I use the digital zoom during playback because of the number of pixel in the recorded file. Maybe I am looking at this all wrong.

Thanks

You are, the benefit is when you zoom in for identification.

 

But surely you will gain nothing as the original definition will not be changed and so what you see in zoom will be no better. You will just fill up your hard drive quicker.

You are incorrect on both your statements. First, you will be able to view a clearer picture because as you zoom in the monitor is only displaying a small portion of of the 4mp image. For example, if you zoom in to 200 percent, you are looking at a roughly 1080p image on a 1080p monitor, you have more pixel density than using a 1080p camera. Second, storage space is not affected by the MP rating of the camera, the ONLY thing that affects storage is BITRATE. If you are a systems developer for cctv as you claim and not a spammer, you should know these basic facts about cameras.

Here is an extreme example. This is 1080p vs 4k (I understand the op is talking about a 4mp camera, but the same concept applies)

Watch the video at 1:25..this should help you understand and provide clarification.

You are better off replacing the dvr....

Here is a 720p (TVI) unit with double the resolution as 960h...includes 720p cameras and should accept your old analog cams as well.

Includes hard drive, three year warranty and costco's lifetime return policy.

This unit is also hd, and should also accept your old cameras (but since its cvi, double check with qsee)...

First two will likely be cheaper than the board (if you can even get one) and hard drive...

 

Thanks. I was able to get a refurbished DRV9-4200 from Swann for $149.

 

When the new one arrives I'll duplicate the hard drive and send my original in for them to quote me a refurb. I was trying to do too many things at once yesterday and whacked the OS on the original disk. Doesn't seem to be any actual problem with the hard drive.

For 50 dollars more you could have a better DVR with 720p cameras, full warranty and lifetime return...but to each his own.

Reviews for that unit are terrible https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=+DVR9-4200+

Hello,

 

My Swann DVR9-4200 started reporting HDD Error repeatedly and stopped recording any streams. I initialized the disk several times with no change. Eventually, the DVR stopped recognizing the disk at all. Well when I opened the case, it turns out that a capacitor leaked over at least 1 diode on the PCB. Anyone know where I can get a replacement TCMB03 v110? Also, I want to change the hard drive. Will I need copy a disk image onto it or is the base OS in EEPROM on this system?

 

The system is several months out of warranty.

 

Thanks,

Eric

A look at home depot tells me any mounting box will look absurd.

 

I think the choice boils down to

a. drilling a larger hole

b. offsetting the camera base from the brick via larger screws with stainless steel washer between the base & the brick

Many cameras are mounted to round junction boxes. They look fine. if you want it neat, make a larger hole...there is not much difference ultimately between a large and small hole. You may also be able to modify a siding mount to suit your needs

https://www.google.com/search?q=oudoor+lamp+mounting&rlz=1C1GGGE___US509US509&oq=oudoor+lamp+mounting+&aqs=chrome..69i57j0l2.3839j0j4&sourceid=chrome&es_sm=93&ie=UTF-8#tbm=shop&q=siding+block+&spd=0

You're saying the coax seal procedure applies to the ethernet connection?

it applies to any connection you want to protect from water..otherwise it will seep in and you will short out your cameras.

I suppose that's true (unscrew cams & disconnect nvr) because I'm not using the supplied wiring. It's a good point, I'll keep the box.

 

Guilty of the cheap power supply I thought it had something to do with running it in quiet mode (reduced voltage) but maybe not.

 

I'll have a look at home depot for mounting boxes. My system actually came with 4 bullet cams & 4 domes. The domes are a little better at hiding the wiring, if there's a big enough indent in the mortar between the bricks I might even get away without the mounting box for those.

make sure you wrap the connection in coax seal/silicon tape ..google coax seal..

Ok, I see. The implication being that you'd have to dismantle your entire system to return it.

 

How reliable are these systems anyway?

 

My "always-on" computer needs a new power supply every couple of years for example.

They are very reliable...yes you would simply have to unscrew the cameras and unplug the nvr to return it.

Power supply failure is rare on pc's. You are either using cheap power supplies or there is a power issue..make sure to use a good surge protector or ups.

Thanks for the feedback.

 

The Costco site says one year manufactures warranty though. I called Costco (Canada) and they confirmed one year. I actually thought Costco extended the warranty to two years but they don't.

 

The US site also says one year manufactures warranty. I did not call US support to confirm.

Warranty is not the same as returns...you can return ANY item purchased at costco at ANY time, except for specific electronics that are excluded. IP cameras and NVR are not excluded. There is a tread here where I advised another user to take back a system that was a few years old..they accepted it no problem.

Thanks for the feedback, I'll consider the mounting box.

 

Do other cameras have this same issue? I'm still well within the Costco return window.

 

It seems like an obvious design flaw.

Costco has a lifetime return on ip cameras/nvrs.

This is common in most cameras. Some high end brands have the option a connection inside the camera. You are looking at paying 5x more.

you can use use a juction box, but that will require several smaller holes in the brick for the screws, you might as well make a larger hole..

Seems Dahua is a recognized brand. So, I've hopped on amazon and looked to buy a few 3mp cams, a poe switch.. And dvr.

 

However, it looks like all the dvrs have a single lan port and all the inputs are coax.

 

Is there a known setup that will be around or below 500 for two cameras, dvr, switch, and other miscellaneous parts?

 

Thanks so much!

 

Rob

You have not done proper research. You need an NVR not dvr. There is a ton on info on the forum. Dont just buy gear willy nilly. You will be sorry.

It's obviously too late but yes, these are good cameras for the price. Unfortunately, I'll never consider HikVision again.

 

They are a too much of a security risk as it was discovered that their cameras were installing Bitcoin mining nodes customer networks.

You have no clue....next time properly secure your device.

Good !!. But 1080P X 8 Ch could get you some problems (Network/Traffic/HDD/smooth decoding play back or spot monitoring, etc). But 720P X 8 Ch would be OK, which is Cheap and I recommend. Finally, I do not think you may come across the mother board for your OLD DVR.

 

I don't understand why is it so difficult to locate the board. Could it be that no one in China knows how to repair DVRs and there wouldn't be any still unused? It's not like this was a $50.00 device. I can't even find the website of this Enterprise LTD-2508. A $750 unit.

Give up...you wont find it. Its not worth it. Here is an HD over coax system with the LIFETIME return policy of costco

http://www.costco.com/Lorex-8-Channel-HD-Analog-DVR-with-2TB-HDD%2c-8-1080p-Cameras-with-130'-Night-Vision.product.100218592.html

Find the spec sheet for your cameras and find the POE class or total power consumption for each unit. Once you have that figure do the math. If it adds up to more than 72 watts then you need a different switch or you need to inject power to a few cameras from a midpsan.

 

 

ok thanks. i think this pretty much answers my main question.. the cameras can only consume combined wattage max of what the switch can take in (72w) . therefore when deciding on a UPS for the system, i will calculate consumption of DVR and Switches only, no need to add a per camera wattage on top of that.

 

tnx

If you do this you will overbuy. Suppose the switch has 7 cameras attached and each is only drawing 4 watts...add say another 5 for the switch and you are at 33...why would you use 72w to compute your needs?

I was thinking that for practical reasons it would need to upload files of recording between 30s to 60s. If you imagine the scenario of house burglar entering your home. Knowing that there is CCTV they would locate the DVR first. 30-60s duration files sounds about right to me.

 

Without cloud based backups - CCTV systems seem flawed to me.

This function is not easy to find. If you move to ip cameras, you will find the most can upload jpeg still via ftp while others can also do video. Theft of the recorder is rare, that is why you still see tons of footage recorded.

Pumping tons of data over your internet connection is often not feasible. The best solution is to use IP cameras..this will let you hide a second NVR ANYWHERE on your network. You can also get IP cameras with SD card slots as additional backup.

Have 4 channel DVR with h.264 compresssion and default encoding was D1. Watch playback on DVR monitor is fine. After I made backup copy on USB drive to give to police. I tried to open the files and the show to have .dat ext and Ive tried every codec player/converter but still no luck. Went ahead and changed hard drive in DVR and set to CIF. How do i view files from the original drive

Why do you think changing the drive or setting to CIF (which is much lower resolution than D1) will help with the file format?

Most of these DVR's require you to use a proprietary player for playback...
