We've been advised by the 'expert' that a local council brought in, that we could use hik, as long as its only cameras, and not dvrs, and only if the system was coax based, rather than IP. The basis of the conversation being that if its not a hik dvr, and the system isn't IP, then they couldn't possibly dial into the cameras, as that would have to be via the dvr, which not being hik, couldn't happen. Although a lot of the larger buildings we look after for said council are all IP, as the original design was all done via cat5 and switches on each floor.

Ha guys, some of my thoughts exactly !!! they lost a couple last time, hence the need for this to go 'technical' to avoid loosing kids ! the plan is to have some sort of lane with staff there to ensure they swipe in and out, like a festival. Ta for the stuff so far !!

Gurus of access control, lend me your ears. strange but interesting application needed for an access control system : a scout camp. They want to be able to check everyone in and out, knowing who is 'on site' - this is a one off, for a week. Their usual stance is to have identity cards printed by a normal id printer. the ethos of doing it on the cheap has been mentioned, but I would prefer to build them a system that will last. Now, I'm the cctv man, not access control, and therefore a couple of questions : The system simply needs to keep a count of who, and how many, people are on site. My thoughts are with a 'in' and an 'out' reader each scout waves their card against, connected to a set of traffic style lights, rather than a mag lock. The event staff are there at the gates to make sure people don't bypass the card readers. I was was looking at paxton kit, as it's decent and reliable. It will need to be able to be linked to a laptop so when they ask what time 'little johhny' left, we can tell them. card wise, their cards have to last no more than a week. Therefore, are all these cheaper 125khz cards I see on the likes of eBay, will they work with paxton kit ?. The cost is directly bourne by the organisers so the more cost effective the better. Does This sound ok ?. Is there a better or easier set of software out there than the paxton stuff ?. And will the cards work with paxton kit (I see a lot of their much more expensive cards out there which leads me to think they may not !!) ta all !

I thought there was something wrong when we put in an ndi anpr cam, it was pulsing at about 50hz on the IR cam. Thought I was doing it wrong, until I broke open the manual..........

Why not use some of the 16ch rack mount to balun units, then you can use a few cat5's to your new location, rather than a massive bundle of rg59. 4 cams per cat5. its sill an analogue signal, and looks neat too. (and is a heck of a lot easier to run cable wise than your 94 runs of coax)

Im sure I have seen the same unit offered by adata. As some sort of vehicle based ptz.

there are cameras now out there that are direct IP connection at the camera end, so just need to get fed into the network, and some that have all the processing in built, so you just use a web client to view the system. Don't know how happy I would be though with a camera which also contains the processing kit, and potentially all the plate details, stuck outside.

We looked into anpr for a customer at events - so a temp solution that went up and down on tripods or scaff poles for each event. In the end, we used pips anpr for the kit and the expertise. Some of the other companies were very stuffy about dealing with something where the client had already purchased their own server and screen, and simply wanted the software, and maybe a camera. (they already had derwent REG cameras). Pips were incredibly helpful.

Not forgetting about those customers who use PED terminals and process card transactions via their tills. We had one of the large players be threatened with removal of their credit card processing via their tills, as the cctv kit recorded an output from their 'journal roll', which printed the entire credit card number onto the screen.

I tell you what, you give me your address, and I will come and fit it for free. Whilst I'm at it, what do you do for a job, so I can ask you lots of questions, then go do it myself. perhaps googling any of the terms I have used would give you an answer in less than a second. harsh ? - maybe, but too many people seem to think that this is easy territory these days, then come crying back when they get it so wrong.

doesn't some sensormatic kit use all 4 cores from a belden cable, rather than the standard 2 of other cameras.

IP camera x 4 cat5/6 cables x 4 nvr x 1 camera psu x 1 hdmi / dvi monitor x 1 network switch x 1

Those horrible letters on a box ......... CCA - copper clad aluminium. When you know you are subbing for a really cruddy company. chaps for the recommendation on the QED stuff.

I used the cat5 shotgun from adata last week. Actually nice stuff to work with, compared to the dirt cheap cat5 some supply us with ...... Thanks for the replies gents, I might switch to cat5 and baluns for installs now, to future proof it, and also means in a pinch I can run a further 3 cameras on the other pairs.

I've always installed coax and some flat twin flex for power to cameras when doing my own stuff / private jobs. When subbing, it has always depended on what we were supplied at site, some gave coax shotgun cable, some reels of flex and 59, or cat5 and flex for power. Now we are installing more and more cat5 type cables - not only for ip systems, but also for analogue stuff, on the premise of 'makes upgrading easy'. Last week, we had 10 reels of cat5 shotgun cable, with a run to each camera, balun on the end to convert to bnc. What are people using ? Is everyone still using coax , or are people putting in cat5 even on analogue installs ?
