IP or analog cameras?

Are you using POE? If you are using CCA you would be in code violation in most parts of the country. Look at the numerous posts about CCA on these forums as well as other internet resources.

we always used an off the shelf POE switch (Netgear usually) that are rated at 48v and had no issues with AXIS

coax of cat5? first question needs to be answered. Are you getting paid for this install if so why would you make it so cobbled up? make individual runs for each camera and use correct wire form what little is posted I would at first make sure I have the proper seperate power wires for each camera. I know you can use a balun with cat5 and use the other pairs for power but I am not a big fan of that approach.

Are you looking for a KVM extender? that would have to be run over cat 5 but you should be able to get the distance you want. an KVM over IP would allow controls anywhere on your network. It may be worth the money to install the cat5 as that would give you a complete solution.

If you can. run the cables on the inside look up on google various methods of fishing the walls. I would attach the cables to the floor joists to keep them from getting wet and generally being in the way.

I have used keyscan in several installations both large and small tech support and training are very good.

Now that the Russians are players think they will take any refugees?

I think the name of the company is STI. They make a line of protective enclosures for fire alarms clocks etc

Just go to the various websites of the mfg and their speck sheets will tell you what cams have autofocus. for instance geovision has several pages of cameras with various features from motorized zoom varifocal etc. more features and bigger brand names will of course mean more money axis, panasonic etc

I would take a know good camera and swap it with one of the blue ones. If it works it could be a surge damaged multiple cameras also see the next post in this forum as to how to check voltage at the camera. I also would check the voltage at the power supply for the good cameras vs the blue ones.

you could convert but you would need a pair of fibers to use an Ethernet connection.

you can buy housing with a wiper which may be cheaper. http://www.2bsecurity.com/cctv-camera-housings.html Note I know nothing about this company but this page shows some washers and wipers for camera housings.

ditek has a line of lightning protection for coax and ethernet.

I am sorry I don't know the name of the product, but there are programs that will PING an address and send an alert whenever it does not get a response. That could be used for any network device.

Look at axis they have a 2 door POE system that would allow the 2nd reader. The solution you are looking for is one that requires a person to card out as well as in (or keypad) the software from most access systems keeps track of in and outs. If you were to use the axis it can power a door strike so you could eliminate seperate power supplies ALso the data base is in the unit so you can access the unit from anywhere on your network.

If you go to the storage setup page there is a tab to add additional storage spaces so you might have storage 1 on hd 2 with storage 2 on hd 3 etc you have to assign cameras to each storage section.

looks like the center pin is missing as that is a male connector

I would go IP with wired cat6 run spares if possible POE switch NVR or PC with software your choice. Buy from a US dealer that provides tech support even if you pay a little more up front you will be happier. Just look through these forums and see all those seeking advice about cameras purchased from overseas with no manuals and no warranty

We did an install at a polishing plant and the air was full of very fine metal dust and such. They installed air lines by every camera and either kept a constant stream of air on the surface (these were domes) or had a setup where they could give the camera a blast of air when needed I really do not know which method they ended up using.

seems like the only time any dvr/nvr stuff should be in this section is if it relates to tying the access control and video systems together.

Check out some of the larger UPS mfg websites APC, Tripplite minute man etc they have all kinds of tools for run times and types to use for different kinds of equipment. We used a lot of tripp lite stuff over the years and had good results.

Do not know the spec on the microphone but would look into that. Many of the microphones we installed required 22 gauge 2 conductor shieled with drain wire. If outdoors then outdoor rated as well.

did they come with a manual? I am not familiar with that camera but some are 24v ac or that is an option. What are you going to use for a controller?

Brand names still carry some weight with the customer. If they have had a good experience with a certain mfg they will lean that way. Warrenty, quality components and support are all factors. I would rather sell an Axis camera than a no name who knows where it came from for a couple of reasons warranty, support and a quality product. I also would rather mark up a 500.00 camera than a 100.00 camera assuming the same per cent markup. Bottem line if you can't make money on it, you are wasting your time. What part of the market do you want to compete in?
