Converting to IP

[wbryce 0]

Hi,

 

In our home we have 10 cameras around the property exterior, all set up with underground coax so looking to to use a good cost effective ethernet over coax / POE set up. Can anyone recommend base/camera EOC units? Had a look at highwire powerstar tx/rx units, but at £300 for a pair, plus the camera over 10 sets, It maybe cheaper to lay the wire.

 

A flaw which wasn't picked up while designing our property - all the coax ran into our underfloor heating service compartment, most of the analogue equipment has a short life span due to the temperture so running it into our network and having the juicier electronics elsewhere seems to be a better solution overall, unless someone can point me to a very robust DVR unit that may survive the heat.

 

Just trying to find a cost effective solution. My knowledge in this area is limited to being a home owner with the equipment.

 

Thanks in advance,

IP can run over coax, but pricing is a factor. It involves using a device at each end of the coax. One by the camera and one by the NVR...for each coax. A pair of devices are about $100 on the low end, but there's device-pairs that run $200-300.

 

For a business that has invested thousands of dollars into their coax installation (and a new Cat5e install would run thousands), IP over coax can be a dollar-saver. But for a residential situation for a do-it-yourselfer on the weekend, that's typically more than the average budget of a 3-bedroom house.

 

So it leaves 2 other options:

1) pull out the coax and put in Cat5e/6 cable - not the most expensive, but significant time.

2) Go to one of the HD-over-coax solutions such as TVI, CVI, AHD, SDI, etc. These top about at about 1080P (about 2 megapixel-ish), so you're not getting those 3 or 4 megapixel images, but it is definitely much better than regular analog.

 

Whichever one you go with (TVI, CVI, AHD, SDI, etc.) it means sticking with that specific type...so if you went SDI and a year or two a cam goes out, then you go get an SDI cam.

 

Personally, SDI seems to have the slightly better imaging to me...slightly. But for my HD-over-analog customers, I'm most always using TVI for one of these reasons:

* TVI allows for very long cable runs (not an issue for an average residential/house situation)

* TVI is open source, so a lot of companies are on that bandwagon (unlike...say...CVI)..easy-peasy replacements

* TVI is real low cost these days
