Couple of Questions about IPC-HDW5231R-Z

After reading a lot about the Starlights and nayr's review, I am sold. I am going to be putting up about 13 of these in a warehouse, but needed to know a couple of things.

Most of them will go inside the warehouse and hang down from rafters. That is easy, but two of these are going outside. Since domes are not good for this, I want to use the turrets, but since this is a commercial building, I am concerned with vandalism. Is that just a risk I take for the quality and other positives of the turrets or is there some way to help with vandalism?

Secondly, this building's system is currently analog with coaxial cabling and the company does not want to pay to rewire all the cameras. I have heard of the coax to Ethernet adapters. Any recommendations with these, i.e. models, experiences?

If you cant replace the wiring then look at these:
HAC-HFW3231E-Z | Dahua Technology
HAC-HDBW3231E-Z | Dahua Technology

and a Dahua Tribrid NVR that can handle IP cameras for any new wiring.

Nayr, are both of those going to have the quality that the turret has? I know the turret has the motorized lens, which it looks like the dome you mentioned does also. In fact, most of the specs look very similar for the lens.

I just want to get as close as I can to that turret if I am using the coaxial cabling.

If it is close, then there is no reason to worry about the coaxial to ethernet adapters, but if it is that big of a difference, am I hearing that you don't recommend the adapters?
 
They seem to perform pretty much the same as the IP Varifocal Turrets, you can find some sample images here: New 2MP CVI Starlight cameras and S3 Generation DVR

You wont get the IVS (Linecross/FacialDetection) on the camera, You'll have to get an NVR that is capable of doing that work.. I think the Bullet/Domes are only offered because they have physical zoom in/out buttons available under an access panel, the turrets dont.. You'll have to use those w/these CVI cameras to adjust zoom.
 
Would be cheaper, and smarter just to run new wiring than wasting a moment w/those things.

If you want IP, then run cat5e/cat6.. If you cant run ethernet, then use CVI as a band-aid.. dont try to convert Coax to IP network, it'll cost far more than its worth.
 
Yeah, I completely understand that from a materials cost perspective, i.e. Cat6 plenum costs, but adding in the cost of labor, this is where it starts getting a little out of hand. Putting on your contractor hat for a minute, how much did you guys charge back when you worked for the startup to rip coaxial and drop a 300' run of cat6? Then you multiply that by about 14. Obviously not all of them are 300', but you get the idea.
 
less than the $200 a run that your looking at for those baluns.. usually about $150 per drop is average.

Its usually easier with existing wire in place.. attach the cat cable to the coax with some tape and then yank out the coax while pulling in the cat.. Last time I replaced Coax w/Ethernet it was a piece of cake and took half the time it would have to fish it all through freshly

Yeah, that's what I would normally do. In this warehouse environment, that may make it harder than normal as each cable is attached to the rafters the whole way to the camera.

I will need to look at the quote for the camera system my current employer got. I believe they wanted to charge us like $10K for new cabling for only like 16 cameras. I thought that was ridiculous. They are going to put in these adapters. Also, they are using Axis... that tells you enough...

I need to get involved and make sure this gets resolved.

I think I could charge $300 a drop for this rewiring project. Let's see what they say.
 
thats insane, $625 per run.. what $60 an hour for 10 hours of sitting on your ass and $25 worth of cabling? or is it $600 an hour of labor with $25 worth of cabling?

Ive seen parking lots trenched up and repaved over for that kind money..

You can branch off switches, get a few of these and it might save you alot of work for bundles of cameras close to eachother: 1 to 4 PoE Extender thats a nice thing about IP is you can network which can reduce cabling costs.
 
most runs can be done by a skilled wire puller in under an hour if no drywall needs cut and patched.. I would think in an open rafter warehouse it'd be pretty straight forward, most of the cost being renting a cherry picker tall enough to reach the rafters.. but tha'd make the job much quicker, a team of 2-3 guys could probably get it done in a day..

lets say 3 guys @ $75/hr ($25/hr each), $300 a day for a mega cherry picker, and 2 days of 8h just incase they slow fucks.. now double that so the profit is worthwhile and the numbers still dont even come close to what your quoted (~$3600 by my math, or about $225 per run).. Fuck those Axis guys, contact some low voltage contractors (Telephone/Ethernet specialists) and have them replace the wiring and you already know what cameras and recorders to use.

For $10k you could buy a used cherry picker or forklift for the warehouse and keep em when the job is done.. and still have cash to spare.

Wow, for 25$/hour you are working in amerika? For this money in Germany you won't get a qualified craftsman. Normally the minimum is above 45 Euro/h for such easy low qualified workers.

But I can imagine, if cables goes over cable ducts between many other ones, it's impossible to pull them.

It's better to get several calculations, the price differences between them can be hudge. I agree, that the price looks much too high.
 
$25/hr is damn good pay in the US; according to this page the average is $16.37/hr
ERI | Salary Expert - Low Voltage Electrician Salary in United States

dont seem about far off from what Ive experienced, I got paid $12-14/hr in the late 90's to crawl around in attics and yank telephone/network/cctv cables around.. far too much work for far too little money, I didnt last long doing that shit.. but it was considered damn good money for a teenager doing manual work in BFE... the union workers at the local plant were making $30-40/hr pounding rivets into boeing planes and that was the highest you could go in the local economy w/a blue collar job. (its what my dad's been doing for the last 30 years)

I think nayr has nailed it as usual.
If you do decide to go with some CVI cams where new cable isnt possible/affordable, the 3231 Starlight CVI bullet does come damn close to the IP 5231R-Z. With the XVR series recorders you can always go back and swap out any given cam to IP as you get your cabling sorted out as they'll handle CVI and IP both.

Here's a sample day and night video from the 3231's (Make sure and choose 1080p and go full screen)

Wow, thanks for the pics bigred. Those are pretty close. They look amazing.

Nayr, can you cluster the Tribrid DVRs? I noticed there weren't many 32 channel ones and I am already putting 14 cameras on the 16 channel, I need to have expand ability.
 
SmartPSS and the other dahua apps handles multiple NVR's just fine, the clustering options are for high availability so you can have a spare NVR on standby... @bigredfish do you have a clustering menu on the WebUI on your Hybrid?
