matthew.brough Posted July 25, 2013 Share Posted July 25, 2013 Can you elaborate further on solution to a problem, please. We are talking typical scenario: driveway, garage, shop, warehouse, vandals, thieves not industrial espionage, casinos, banks, nuclear power plants, terrorists, drons That's completely irrelevant. IP is IP. Doesn't matter what it's bolted to or threat level. Same with the other things you want to understand. 1/2 of what you want to know is nothing to do with security. It's networking. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
fozzies Posted July 25, 2013 Share Posted July 25, 2013 To be fair, your project will give you a better understanding of all you mentioned other than Ip, Lan, and especially wan. For those you need to study IP purely, ignoring cctv completely Link to comment Share on other sites More sharing options...
quasar Posted July 25, 2013 Author Share Posted July 25, 2013 Let's forget IP for a second, it was meant as a future addition. I guess I can buy an IP camera, link it to my home lan and have a play with DVR and camera networking separatel. 960H or D1? 8CH Samsung SRD-873D looks interesting, 4CH version is only D1 Link to comment Share on other sites More sharing options...
james.wilson Posted July 25, 2013 Share Posted July 25, 2013 960h is better, but hd-sdi is the best at medium end gear securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

quasar Posted July 25, 2013 Author Share Posted July 25, 2013 Upgrade to IP from HD-SDI in future means re-cabling A big no no I don't want any half measures and the only reason not to go 100% IP at the moment is cost. There's a wide range of cameras but most DVRs I can find don't support 960H Whats the point buying a 700TVL camera and connect it to a DVR that records D1 Link to comment Share on other sites More sharing options...

quasar Posted July 25, 2013 Author Share Posted July 25, 2013 What 1080hd IP camera? AXIS? Anyway your £200 IP camera is still at least double the price of a reasonable analogue one isn't it? Who would use HD-SDI if IP were the same price range Link to comment Share on other sites More sharing options...
james.wilson Posted July 25, 2013 Share Posted July 25, 2013 I'm going down the sdi route. Long term id say ip will rule but not for a few years Imo. But who knows how high sdi will go. Cheap ip cams have huge issues currently imo securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Who would use HD-SDI if IP were the same price range You haven't looked at the other end. It's ok saying analogue is £100 per camera but you have forgotten that something needs to record these cameras. Quite often IP works out cheaper in total cost ownership terms than analogue. IP signalling is far cheaper than analogue but the market is full of analogue so if your argument above held water Redcare and Dualcom would be bust by now. The main reason IP devices are not used IMO is because them majority of the people in the industry are too thick to understand it. www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...

We are talking typical scenario: driveway, garage, shop, warehouse, vandals, thieves not industrial espionage, casinos, banks, nuclear power plants, terrorists, drons Others are much more experienced on the practical side, I'm more technical/theory orientated. What I mean by "solution to a problem", is a system proposal to secure your premises. First thing would be a site survey, to identify weak points, points of attack (so to speak), lighting, etc., then what type of camera is best suited to cover an area from which mounting point, etc. After this is done, is when you would look at your options such as transmission method (analog, IP, HD-SDi), recording, etc, while taking into consideration which functions you may like to have (phone access, storage times, etc) and ofcourse your budget. The point is that the first steps above, apply to all cameras whether IP/analog/HD-SDi and apply whether you want Internet access or not. Concentrate here first especially if your on a tight budget as it will end up costing more to put right. Link to comment Share on other sites More sharing options...
digitalwitness Posted July 26, 2013 Share Posted July 26, 2013 What 1080hd IP camera? Who would use HD-SDI if IP were the same price range I would ask this another way, on a installation where both IP and HD-SDi are viable options, why would you over complicate it with IP? While IP may not be a challenge for most, it does introduce more opportunity for failure with no real benefit (in such an install). Besides, the only thing HD-SDi is missing is volume, at the same volume, equivalent quality HD-SDi and IP cameras, the HD-SDi camera would be much cheaper, infact some have said a HD-SDi camera would be cheaper than an analog camera (negating the cost of the higher res sensor ofcourse) because a HD-SDi camera does not need a digital to analog converter. The reason it hasn't got the volume yet is the pace at which analog prices dropped, making the jump to HD greater and less appealing but IMO it will happen.

It's ok saying analogue is £100 per camera but you have forgotten that something needs to record these cameras. Something needs to record IP cameras as well doesn't it? If you want to use an existing IT infrastructure, software doesn't come for free Quite often IP works out cheaper in total cost ownership I might be wrong but I don't think so. Sometimes, but not quite often. Not yet. Give it 3-5 years The main reason IP devices are not used IMO is because them majority of the people in the industry are too thick to understand it. I think you are too harsh. They may be too lazy to learn new stuff, though What I mean by "solution to a problem", is a system proposal to secure your premises. First thing would be a site survey, to identify weak points It's irrelevant here. I do not want to secure my premises at this stage, I want to test available configuration, settings, networking. Everything will be installed inside/outside my garage, temp. mounting points etc. Besides, the only thing HD-SDi is missing is volume, HD-SDI missing upgrade options. In theory IP has no limit to resolution in future Link to comment Share on other sites More sharing options...

In theory IP has no limit to resolution in future Then is not CCTV you wish to learn, why understand what WDR stands for but not interested in why or where it's used? Just trying to understand what exactly you are looking to learn, I'll explain the abbreviations very quickly if that's all your looking for. In theory, possibly but IP has limits mainly that are based on your existing infrastructure when it comes to upgrades but yes more leeway than HD-SDi but remember IP had been around in security for 15 years iirc. IMO HD-SDi Vs IP is a pointless argument, they have very little in common, if you need what IP can offer, you need IP! HD-SDi is competition for analog not IP, comparing analog to HD-SDi and HD-SDi has many benefits. Link to comment Share on other sites More sharing options...

Just trying to understand what exactly you are looking to learn, I'll explain the abbreviations very quickly if that's all your looking for. I know what all abbreviations stand for. I want to test them in a limited real life situation, play with settings, different cameras, networking, remote access. I don't want just read some specs and view screen shots on manufacturers website. It won't make me a pro, I know that. I could have bought a Dell PC. I built my own. Building, upgrading, swaping components, over-clocking, breaking, fixing hasn't made me a computer specialist but I enjoyed it IMO HD-SDi Vs IP is a pointless argument, I don't see it as X vs Y HD-SDI may be a perfect solution today, but I see no future for HD-SDI . Nothing wrong with HD-SDI , I am just not interested. Link to comment Share on other sites More sharing options...

If you want to use an existing IT infrastructure, software doesn't come for free Actually, with the deal I have with UTC the recording software doesn't cost me a bean. Just the camera. Hence my comment, IP can prove a cheaper option. I might be wrong Correct You can't educate pork I think you are too harsh.

I am more interested in the technical too, why should be obvious but at some point also consider there is a science behind everything that happens before you get to what your interested in. Security and CCTV is about providing useful images in varied conditions, the how it's transmitted or network configured, etc, is secondary. I agree HD-SDi future is limited but not irrelevant.
