Hi guys,

I really hope someone can offer me some advice.

I have a potential client who owns a chain of "members lounges" and he has asked me to install CCTV to the premises. The only trouble is, he doesn't want ANY wires on show. This is a major issue as the walls are padded buffalo skin and silk and the ceilings are padded diamond leather.

So, what I am looking for is a good wireless video transmitter and receiver combo for each camera I install. Each site will be having 7 cameras but 2 are already pre-wired already on each site.

The "lounges" are old buildings in London and as you'd expect have rather thick walls but the buildings themselves are not massive but are over 3 floors. I estimate the longest distance to be 30meters (but through solid stone walls)

Anyone have any experience with this?

Wireless IP?

If no wires, what you doing about power?

Dilithium crystal PSU?

Where the cameras are to be located they are all close to risers that have power in or have local sockets.

I have never used IP cameras, can someone explain the installation process? Do I need an NVR as opposed to a DVR? The client wants to use the existing DVR's on site.

I was hoping someone could suggest a reliable 2.4gHz (similar) transmission device.

You watch to much TV, everyone knows they are not real.

If power is so easy to run surely you can get cat5/coax in at same time?

Re existing DVRs, are they any good?
Yes, you would need NVR/NAS if using IP.
Try get client to dig deep and go poe, that would save on PSU and keep cabling to a minimum.

You met my ex boss didn't you Andrew, I rest my case

He's a bit of a fussy guy, really wants to keep the existing equipment and add to it. The original equipment was installed during a refurb, hence he is keen not to have wires on show and truthfully there is no way to get video cables to cameras without wireless - as much as I'd prefer to have hard wired.

[breff]

I cant see wireless working across 3 floors without any clear line of sight

Are there any existing cameras? You can use SNT units to get 2 video signals down 1 coax, not cheap though

Am i missing smething here?
If you have to get power there, how is another cable gonna make a difference?
Or have you gone for Richards crystals?

Yes, and look what it did to his cardigans.

[alterEGO]

must be a way to cable, i bet we could.

[Oxford]

Have been thinking about wireless IP cameras. What benefit am I going to get using a wireless IP over any other wireless transmitter connected to an internal camera?

Definitely no way to cable the whole building without dropping the wall and ceiling coverings and that is not in the budget for time or money

[digitalwitness]

Have a look at the two prewired cameras, they may offer an opportunity to reduce the distance for wireless, extend a wired network or carry 4 analog cameras each.

Also have a look at what existing infrastructure is there, did they wire for additional TVs, network points, phone sockets or anything else that may have been installed during the refurb that is not being used or can be utilized in another way. You may be able to introduce camera signals into the TV distribution (if there is one) and demodulate them back to composite but I do not see any of these solutions being cheap.

BTW What is his existing equipment that he wants to keep to operate two "pre-wired" cameras?

[Oxford]

I think he only wanted to utilise the original equipment to keep the budget down.

Now, I often use a piece of equipment made by Devolo to transmit broadband over mains. I wander if one could take advantage of this technology and transmit an IP camera signal via this method back to the NVR?

Single or 3 phase mains around building?

[IAS]

wonders at the word SECURITY in the forum title lately ....................ffs sending data round the ring main.

[digitalwitness]

Sorry Oxford but what original equipment? 2 Pre-wired cameras suggests not yet installed but if there is an existing system outside of this then maybe there is possibilities with regards to the existing system for expansion.

[Oxford]

Data around the ring is all encrypted between the transmitter and receiver.

The manufacturer of the oe slips my mind but if I remember its nothing too special.

Single phase mains as found in domestic applications.
Does anyone concur that this would work?
