Hi
just a quick question i need to locate 110v CCTV system but am finding it very difficult
we have a current 240v system on site but it seems that the HSE do not like the idea of the 240v system
i have tried several of my regular suppliers to no avail, any help would be very appreciated
Regards
Geoff

Forgive me but I don't understand. A transformer (heavy yellow box) plugs in to the 240 circuit and your 110 system plugs in to the transformer. Am I missing something.

Sorry Geoff
Not paying attention.
But the reason you have not found a 110 system is maybe they do not have to be. 110 CTE on sites are for (usually) hand held equipment. I don't know your circumstances but will the CCTV be installed an then virtually be a permanent fixture, how about hard wiring it in to the existing circuit

Hi Holly
no problem i had to read my post twice to make sure i was making sense
Its so we can continue to carry Asbestos Removal Works on site
the ironic thing is we have been there for 2 months using the 240v CCTV

Geoff

Why not use a wireless system? - battery operated, much less hassle setting up, easier to take down and move when necessary , and safer....

Parts of the USA do use 110 but at the wrong 60 hz in UK its 50 hz.
Just fit an RCD on the circuit much better and safer than 110 volts.

Try contacting a few "non-destructive testing (NDT)" companies. they use 100v cameras for internal inspections on pipework, confined spaces, etc.
We've just used a company called "OIS" on site.

Hi Paul
Why 110 volts?
You can get vg cctv that runs on 12 volts for day and night, multi camera motion sensing, with 15 inch tft monitor and 160 Gig hard drive. This will record up to 7 days, if you only wish to monitor areas, or you use it direct and monitor 4 areas at a time real time. Cheap at £560.
Google low voltage cctv.

The common terminology i.e. 110 v AC on UK construction sites actually means stepping down from 240 v AC to 110 v AC using a "centre tapped transformer". Therefore, the effective voltage through "each phase" will only be 55 volts and that is not directly fatal if there is contact with a live conductor!
The US 110 volts can be fatal!

I, too, am working on this issue but am struggling to find kit that 'ticks all the boxes' - battery powered wireless cameras with long battery life, reduced voltage receiver and monitor, robust, weather proof, durable, minimal trailing wires etc. etc. Not as easy as a previous posting suggests as I have been on line/phone for several hours it seems. We may have to go down the route of treating cameras as 'consumables' for each job.
I also think we should prepare for the HSE to decide that installing a web-cam is 'reasonably practicable' so that we can monitor the enclosure from the office.
If you have any success finding something suitable I would appreciate a 'heads up'(01942 829804). The suppliers I have spoken to, who have already provided kit to other LARC's, would not divulge the identity of their clients so that I could get some feedback. Possible missed opportunity there!
Regards
DK

Geoff,
I'm also in a similar position but we have been ok with the 240v as the cameras plug into the mains but work on 12v. The receiver and the monitor are 240v but we can control there location and attach an RCD to each lead.

Have I missed something? My understanding is that asbestos enclosures are required to have a "viewing panel". Where is the requirement for camera surveillance coming from?

If you are members of ARCA, the recent publication identified a number of CCTV providers.
We cannot put our hand on the last publication to assist further.

The CCTV is principally to allow remote supervision where viewing panels are impractical and/or to cover 'blind spots' etc.
HSE are quite keen on this, especially now the equipment can be bought for buttons, and deem this provision is 'reasonably practicable'.
