New cat 6 wiring in house

Copper Clad Aluminium :(

Let's not get carried away here, it's a solid copper core and then an aluminium braid. It's coax cable, it doesn't matter.

OP: What do you actually want? If you've requested Cat6, your builder agreed and then has installed something else then ask them to install what you requested. If you just want CCTV then as advised you can most likely use what has been installed.

I had asked the builder for Cat 6 for my CCTVs he hasnt installed them as mentioned and installed something else, I have today asked him to re-run Cat 6 to which he has said no, not without charging me extra - I can try to run them myself, but would be a first time.

The CCTVs I had seen as expained in another post were Hikvision IP cameras, with the following key functions to me, Colour Night vision, 2 way audio and Power over Ethernet... cannt even rememer what else appealed to me, but these things I wanted in my CCTVs

Thanks, so the comment about CCA is not much of concern?

I'll have a look at the up until I thought he was going to install Cat 6 cables, i was looking at Hikvision motion and color view night vision with 2 way audio, but I cannot find the equivalent to those CCTVs. Contacted one of the suppliers and he mentioned purchasing some next thing £120 each whcih was like a converter - That isn't happening I was planning on having 7 CCTVs


I'm contemplating pulling CAT6 via the Coax, especially as the floor boards are open - but I could end up getting stuck half way and

I would always go Dahua with HDCVI. They invented it and they’re No. 1 in analogue cameras. I’m a massive fan of the Dahua TiOC cameras. Which is the product that Hikvision copied to make the camera range you were looking at originally.

https://www.securitydynamics.co.uk/hdcvi-cameras/bullet-cameras/active-deterrent/dh-hac-me1509th-a-pv.html

And they’re £60 each, including VAT. The IP version, which has the same features, is literally double that. I like the bullet as the illumination is better. But they also do a dome version.

https://www.securitydynamics.co.uk/...ull-colour-tioc/dh-hac-me1509h-a-pv-0360.html

And just like the IP camera they do the HDCVI in 2.8mm, 3.6mm or 6mm lens versions. There is even an 8MP 4K version but the sensor is relatively insensitive and you only see out to 25m with the 8MP whereas the 5MP gives to 40m of full-colour night vision. Again, half the price of the IP equivalent.

You get alarm features and 2-way talk.

So, it’s not nearly as bad as you’re thinking. But if you really want IP cameras, and you told the builder CAT6, then get him to pull CAT6 and make good any damage.

Oh - I was just under the impression IP cameras were the best thing and all.... are they not in comparison to HDCVI?

There are three issues to consider. The camera, the way it gets the data to the recorder and the recorder.

With both IP and HDCVI the camera bit (that makes the images) is the same.

With an IP camera, the images from the sensor are turned into an Ethernet data stream and passed over an Ethernet cable to the recorder. With HDCVI, the image is digitised, exactly the same as the IP camera version and is sent to the recorder down a Co-Axial cable.

With a PoE Ethernet camera the power is supplied down the same cable, usually (but not always) from the NVR.

With HDCVI the power is either sent down the co-axial cable from the XVR (what is commonly called PoC) or it can be supplied from a separate 12V power injector which is why the RJ59 cable your builder has installed has a pair of shotgun wires attached to it.

At the recorder end, the recorder has to unscramble what is being sent and record it to a hard disk. A network video recorder (NVR) does this with IP cameras. HDCVI recorders can usually do analogue and IP and they are generally called XVRs because they can cross over both technologies. With your cabling as it stands your system you would need an XVR. Either a PoC XVR or a simple XVR with a separate 12V power injector.

PoE is the big benefit from using IP cameras. But it costs money. So the PoE IP cameras tend to be more expensive than the analogue equivalent. Some IP cameras are also intelligent and can do stuff independently of the recorder. Analogue cameras usually send the signal back to the XVR for processing so the XVRs are more expensive. And the 12V power supplies for analogue cameras aren’t free, so they usually add £5-15 per camera to the cost of the install. So a 4-camera unit might be £60 and the 8-camera unit might be £80 and the 16 camera unit might be £100.

As far as the person watching is concerned, or the way the app on your phone works, you cannot tell the difference between the two.
 
@WJA96 Thanks so much for the detailed info - to add and for my re-assurance, the cables I currently have (coaxil) I wouldn't need a separate power supply to power the cameras? And I can just purchase a PoC XVR to power 7-8 cameras without the need for anything else?
I had done a bit of research and contacted a few suppliers for IP cameras and got trade accounts created, and that I guess was another reason why I was so set on IP cameras, but if the difference isn't much, based on what I understood from your messages, and I've googled it too, then I am thinking is it worth the hassle of replacing the cables - especially as its at my expense, the builder wont budge on this.

I've looked at your links i liked the look of the dome camera, would you recommend the first link rather than the 2nd? You mentioned illumination is better on the bullet, not sure what that actually means?

Also I'm thinking if the cameras are half the price in comparison to the IP ones I was looking at, maybe I would purchase 1 * PTZ camera (wont need mic as it will be high up) any suggestions of how good they are and any you recommend?

I think it's fair to say I'm leaning towards keeping the cables as are.... just hope they are a little future proof, i.e. I do not have to re-run Cat 6 cables if they stop making decent coaxial cameras in lets say 5-10 years

Why do you want a PTZ camera?

Just get 2/3/4 cameras to cover the area, set and forget.

I thought there quiet cool from some of the Hikvision IP PTZ cameras I saw, I presume you do not think they are practical or worth the investment?
 
Ask your self the question:

Am I going to sit on my lounge sofa looking at the CCTV controls to scan for bad people like I work as a security guard in Tesco or just watch the TV?

Yes, this is absolutely correct. AND! With the newest Wizsense cameras, the static cameras can alert a PTZ and start it auto-tracking. So, if I had a 2.8mm wide area camera covering my whole garden, or even the garden gate (which is maybe 30-40m away), it would detect movement at the gate and that would be good. I’d get an alert. With the new cameras, the TiOC can tell one or more linked PTZs to move to a preset position ie. the garden gate, and do human or vehicle detection. Once they lock onto the specified target, they track that body until it stops moving or it moves out of their field of view. And because it’s zoomed in, it’s a nice big clear image of the person or vehicle you’re looking at.

It’s properly clever, and it works the way an operator in a control room would. Only it never sleeps and it very rarely gets the tracking wrong.

In general though, I would absolutely agree, just saturate the area with static cameras and leave the PTZs for town centres and football grounds.

Very cool

I will look at PoC CCTVs as that is the advise im getting that I can run them off the cables I have currently installed.

@WJA96 the 2 you have mentioned in a previous posts, i presume they are not PoC as I did not see that in the specs for both cameras?
 
wow, this may be getting way deeper than I anticipated... so i'd need to run another cable to power the cameras and that cable would run to the fuse box?
