Anybody a CCTV / Security expert?

Recommended Posts

Hi guys and girls, I really want to install a cctv system in my house with internal and external cameras. I would like these to be live i.e connected to the internet so that i can view them through my iphone (via an app- first one i have seen is called icatcher but i beleive there are a few).

 

anybody have experience of this?

 

thanks

I've sent you a PM mate!

 

Regarding that UTILITY - to figure out your CCD size / depth of field / viewing angle + other calculations (relating to whether fixed focal length / variable focal length is the right way to go); download the tool below, and have a play with it.

This company is not bad on price either, helpful guys (...but their cams are a bit more expensive than the other place I suggested)

 

Good Luck

make sure the resolution is D1 spec 25 frames per second across all channels which is real time

 

cheaper stuff drops the resolution to 12 or 7 fps and the quality isnt as good, cameras i bought seperatly

omg, i love this forum. i have never posted a topic on here and got no response or crap response. Everytime the forums comes up trumps. thanks to everyone for taking the time to help with a non car related issue.

 

I'm learning from pm's and replies already. Am i right in thinking that its the DVR that enabled web viewing rather than the cameras themselves?

:thumbs: yep, and if you got a router inside your lan you need to setup NAT to the DVR, remember that it'll be public facing... (so keep it as secure as you can, https and good secure password)

lol, thanks for the reply but you just said alot of stuff i dont understand :) I have broadband through a router with wireless that is protected by WEP?

WEP....... :nono::nono::nono::nono::nono::nono::nono::nono:

 

WPA is the way to do it, ask Doogyrev, he will kick you in the nuts if you use WEP........ :lol::lol::lol:

Well, is your DVR box going to wired or wireless? What make is it? I'll give it a bash to try and explain (not the best gifted doing that...)

 

IF it's wired:

 

LAN cable from DVR will plug into the broadbad router (if it has more then one switch port), once you start the DVR it will more then likely get a DHCP address handed out by the nice broadband router. (just like when you start your pc/laptop) that address will not be publicly accessable. Your router hands out 'black' IP's. The routers job is to take this address and NAT (translate it to a public address, look at it as a unique worldwide postcode). For you to access the DVR from outside your routers network you need to access the routers external address (postcode) once you hit this address the router won't know what to do with it unless you tell it you want to send any packets hit on a certain port to the 'black' IP on the inside, by default it'll drop this if there is no specific rule setup for it... not sure you're following this, not sure I am :lol::lol:

 

Get me the model of the router and I can check how to do it and write you a guide... in short you need to do some work on the router to be able to access the DVR from the outside (from a sunny beach somewhere :lol: ), set a static IP on the DVR or use the MAC address to reserve it in the DHCP server... etc. Sure PM me the model and we'll take it from there.

Actually WPA is hackable in theory so WPA2/Enterprise is the way to go ;) ANY of these with a PSK (preshared key) are hackable. WPA/Enterprise is very hard to hack *Havent heard of any managing it... it changes it's key's in every packet so really hard to 'sniff'. Make sure if your DVR and cameras are WIFI that they support at least WPA, WEP shouldn't be used! *EVER

cool, i imagine im going to go down the route of wired cameras to avoid these issues of hacking.

 

ive pm'd you the model number

go to www.whatsmyip.org and pm me the number thats at the top after:

Your IP Address is xxx.xxx.xxx.xxx

 

:thumbs: Good call on not using wireless, then again it might be turned on without you knowing that it is?

PM doogyrev, he has a friend, really nice guy, who does cctv stuff... :thumbs:

Too right Paul, nut kicking all the way with WEP users :bang:

WPA has been partially cracked but not fully, no one has managed to crack the encryption keys used to secure data between devices. There is nothing wrong with using WPA as long as you use a decent PSK with 12 or more alphanumeric/special character passphrase..................... or your a Bank. For home use its fine :thumbs: There is still quite a lot of kit out there which is still not WPA2 compatible.

 

Using WPA2/AES (known as WPA2/Personal) preshared keys is as far as I am aware unhackable. WPA2/Enterprise is certificate based authentication that also uses WPA2/AES which you will only find in business' or environments with server backends......... utterly impossible to hack :thumbs:

make sure the resolution is D1 spec 25 frames per second across all channels which is real time

 

cheaper stuff drops the resolution to 12 or 7 fps and the quality isnt as good, cameras i bought seperatly

 

Hey jollyranchers

 

What make is that DVR? I seriously doubt that a sub-£1500 RRP DVR can handle 4 x D1/25fps (That's Casino grade CCTV); many of the cheaper DVRs are made in Korea - and 'claim' to do full D1 @ 25fps across 4 channels (on a 4 CH); but in reality they don't.

 

D1/6fps across 4 cameras would consume 6.1/4 Gigabytes of Data (per CAMERA per DAY); so at a constant bitrate (CBR) for D1 - 4 cameras would eat 500GB disk space in 20 days.

 

D1 (...or 4CIF) is 704x576 resolution - hence the massive amounts of data required to support D1.

 

If you lower the recording quality to CIF (352 x 288 pixels) or even 2CIF (704 x 288) @ PAL standards (625 lines) then maybe possible for 4 x cameras @ 25fps (real time);

 

When you stream the CCTV feeds over the internet (..or remote view via iPhone / Android) - it usually transmits in a much lower resolution known as extra-stream (usually the QCIF quality (176 x 144 @ 6fps) - because at the higher quality / bitrate - you'd 'eat your mobile data tariff' in minutes; :lol:

 

Let me know what make you have, and I'll check it out.

Wow - cracking bit of kit for the money jollyranchers ! Top specification 4CH DVR for an excellent price ! You can't go far wrong with this... nice find !

 

yep its a corker of a spec for the money , had a look at quite a few others too

Excellent. Ive been thinking of CCTV for a while, and just did a search on here to see if anyone else had fitted a system recently. Knew it would come up with something.

 

Will read through the links etc. and do a bit more research. Been looking on the net over the last couple of days and omg theres about a million different systems varying from £200 incl cameras upwards! Argh!!!
