boomeranging

Only one camera out of 6 is doing this, it was fine before. I changed out an adapter (that supplied power to all cameras as it failed) and after connecting to new adapter I got this issue. I know power is not the issue because I already tested this camera with the other power slots. What would cause this?

It’s coax, there’s no resister anywhere. I’ll reterminate and see how it goes. I only really just unplugged and plugged in the coax and power cables- no modifications on the camera/cables.

Already tried but I see what you're getting at. I'll maybe just cut and reconnect the cable.

Problem solved. One of the two hard drives died and prevented a boot up. Fan operation irrelevant.

One camera froze (not uncommon) so I restarted the NVR, after that only a grid would display, no mouse pointer, no beep upon bootup. Hard drives still click away as if it were rebooting. FYI the cpu fan died a couple weeks ago but since the unit continued to work I delayed replacing it. I replaced today but the above happened. 2 green led and 1red (by battery) light on circuit board are on. What could be faulty? Dahuae (dahua rebranded, 8cameras, no built-in poe).

I have two 10/100 switches 5 x 3mp cameras. Switches are connected in series to router. Switch A ->Switch B -> Router. I noticed disconnection problems because the nvr monitor shows a frozen picture for the cameras at A (meaning the connection has been stopped/disconnected). Any idea why this would happen? Average current transfer rate is just 3000kb/s for the cameras. Once I unplug Switch B and reconnect, the cameras work again.

I have 6 x 3mp cameras. 3cameras in garage, 3 in house. I will need minimal 2 switches because one will be in garage, one in house. POE utilized. A) I would like to connect the garage switch ---> house switch ---> router (in series). I know if they are unmanaged this config will not work. I know that B) unmanaged switches all need to terminate at the router. My house layout creates a problem where I cannot use B. Q1) When do I need a gigabit switch? eg. 7x 3mp cameras? Q2) Do I need 1 managed switch or 2 for config A?

Yes it is apparent that gigabit switches would have no problems with most modest setups however my question is: Would my 6 x3mp camera operate well with just 10/100 switches? The cameras so far run at 4000kb/s.

Thanks dan732. I appreciate the feedback.

Thanks for the help guys. From what I read I think: A) I just need a cross cable between my two unmanaged (no uplink port) switches. I'm still unsure when I would (if ever) need a gigabit switch. The most ever I would use are probably 7 x 3mp cameras. (The nvr can handel 16cameras.) For reference I have a ZyXEL ES1100-8P 8-Port Fast Ethernet POE Unmanaged Switch Zyxel es1100-16P unmanaged POE switch

My NVRX-16 was dead on arrival from a reputable dealer N E L L...., for the price it was very cheap and flimsy. So I'm out shopping again rather than exchanging it... and since they don't have a different brand at the same price. Could anyone recommend a retailer and an 8channel highdef highbandwidth NVR for (8x 3mp cameras) ? You could PM me if you can't type out the retailer name here. Many thanks.

The item is warranted, I'm declining it and refunding. the vendor says their units are rebranded. Please focus on my question. I'd really appreciate it.

Thanks all for your input but it brings me to my original question: I'd still like to know a respectable retailer selling Dahua. pls recommend the model as well- budget is $500. Not to worry, the supplier and I are in good communication. Thanks

I have an NVR which is a rebranded Dahua. Somehow this forum blocks the real name and rewrites it for me! Sorry for the confusion. [MOD: Please do not try to defeat the word censors]

Background info: newbie here going DIY route So after spending countless hours on this forum I've only decided that I'll use the hikvision ds-2cd2032 fixed 4mm. I'm struggling to make any further decision so it's time to ask for help. I am a handyman but hate using windows OS-have only a mac laptop + ext. monitor now. help request I'm looking for ease of use, leaning toward NVR setup but not sure what make/model will suffice my current and future needs. It's either hikvision or dahuas I guess... for my budget. I plan to be able to view the cameras through my iphone and computer. I hope to have monitors set up in 3locations eg bedroom, living, garage and could utilize an ipad in the future. I heard if I go PC route I can use POE switches and not have to run the cat5e cables to back of house. Currently I do not own a windows based PC (I can invest/setup a basic one with no problem). I hate playing with network ports/firewalls etc. and am not good at it so that's the main boundary and would rather not invest in the time to tinker that way. I plan to purchase the hikvision from amazon as it's $180shipped to US and seems to be the cheapest online, even after comparing with aliexpress. FYI I'm in Canada. 1) Please recommend all components that is need for PC +blue iris route, or NVR for my current and future needs. 2) Please advise on the popular places to shop for the NVR. 3) Can I setup the NVR/pc at an enclosed location eg. closet and still access hd video stream on computer? (I know HD stream is not possible with ipad/iphone etc.). desired current plan 4 cameras: 1 in front of house, 1 at back of house facing garage, 1 on garage facing house, 1 in garage. monitor over internet, auto-record to cut out motionless scenes, setting options to turn ir on/off via program. I guess I don't need to be too concerned about recording frames/sec as most recorders should do just fine? future plans 2 cheap cameras ones for side corridors, 1 camera inside house hallway, receive audio from garage, 1camera vandal dome for garage eaves on back alley side to monitor passing traffic. total cameras 8. possible detached IR if needed. Application: (see pictures) 2story above ground house: (front to back) 2ft flight stairs-> 33ft front yard -> 60ft deep house -> 33ft backyard ->enclosed garage->back alley, 3ft wide corridors on both sides of house. Total current Budget $1500 4xds-2cd2032 $180= $680 bulk cat5e 1000ft $50 (i already have terminals) UNDECIDED: NVR or computer based Microcenter+poe switches, no ups.

Thanks a bunch for the very detailed information slkdesign. I really wasn't expecting someone to put that much effort in a reply! It's a personal choice but I try to reduce the amount of radio waves in my environment. I've even taken the trouble to run LAN cable directly to my laptop to avoid using wifi. This and also the possibility of interference and transmission issues I would go with a hardwired route for all my cameras. The dropcam pro seems to garner good reviews on Amazon I'm sure it'll suite well for an easy installation. [MOD: Edited out banned retailer] Keep us updated with your Synology gear!

So what upgrade of NVR from Dahua should BigCarbs acquire inorder to solve his lagging issue due to the excessive data load? BigCarbs have you resolved the issues?

Apparently yes they are compatible. http://www.cctvforum.com/viewtopic.php?f=5&t=39142&p=238331&hilit=dahua+nvr+with+hikvision#p238331

Anyone? Or is my post too detailed?

Just curious. What model cameras are these? The shots look great.
