I've cavity walls but with insulation. Do you know if it's possible to run cables up insulated cavities? It's the small bobbly insulation. Id have thought that it would be difficult enough to run cables up a wall even without insulation. How did you manage that? I was originally thinking of just using powerline adapters where the cat 5 cables enter the house but cables would be good if I could get them up the inside of the walls.Too high. I fitted mine up there when we first moved in as it was quick and easy, but you can only get an overview of the area or the tops of peoples heads. I moved them down to 2.5-3.0m and it’s a much more appropriate height. I ran the cables up the cavity of the house to the loft so you can’t see them.
I was reading the reviews on ip's website of the Hikvision DS-7604NI-K1-4P(B) | 4 Channel Network Video Recorder. A couple mention noise and one guy seems to think it has a fan.Looks like the fanless 4ch is a new model, "B", maybe they'll do the 8ch fanless too in time.
Hikvision NVR Noise figures
Hi. I have been looking at the Hikvision data sheets for NVR noise,specifically from the fans and so on . I cannot find any published dB figures for the NVRs. Am I correct in this assumption ? I am considering replacing my DS-7608NI-K2 / 8P - it performs really well but the noise drives...www.use-ip.co.uk
-Slight irritation is that the unit has a fan which is a bit noisy so bear that in mind when considering where to site the unit(Posted on 4 January 2018)

Our house is a new build so it also has insulation. White fluffy stuff. What I did was drill a hole at an angle going up where I wanted the camera, then using electricians rods (C.K Mighty Rod Cable Rod Set 3.3m 15 Pieces) I fed them through the hole and into the loft. It's a bit tricky but with some wiggling and the flexible end attachment it doesn't take long. Then attached the Ethernet cable in the loft and pull the rods back through. I used one of these to attached the cable (Super Rod Super Grip Cable Connectors Pack 4-15mm 4 Pack). The harder you pull, the harder it grips.
Thanks for this sound advice. Yes, definitely worth checking integrity of cables after pulled through.Be very careful dragging Cat 5 / 6 cables. They are not overly robust and it is quite easy to snap the conductors. Never try and drag a cable if it feels stuck or is not moving. Try and gently ease it back and try drawing it again. It is a rookie error to try and jerk or snatch a cable that wont move, you will most likely damage or snap it - this is especially important when trying to pull cables through cavities or dry liners. The cable should always be moving relatively freely. I often try and draw a pair of cables together as it improves the overall tensile strength of the cable (but also increases it resistance too). I tend to bond them together with tape at 20cm intervals for the first metre or so.
Its always good practice to check the cable continuity as soon as you have dragged it rather than waiting 2 weeks to find out that you have damaged the cable during install.
With regard drawing up cavities - you may find obstructions, depending on where you are drawing your cables. Things like cavity trays, snot, strapping, half blocks / bricks etc can sometimes foul parts of the cavity.
Final advice - drawing cables is ideally a 2 man job, 1 to feed and one to draw. Most of all, be patient.
When I spoke to my installer about this method he did say it would add a lot to the price as it is more time consuming.
Im trying to picture how you got it out at the loft. Did you drill a fairly large hole at the loft above where the camera hole is to aim for? I'm amazed that anyone could catch that loft hole themselves feeding up from the camera hole.It really doesn't. you're still drilling a hole in the wall for the cable to pass through, you save time from having to pin the cable to the wall as it's inside the cavity, but yes it can be a bit tricky to get it into the loft. I did the first one and that took a bit longer than the other 2 I ran because I picked up the "knack". it's the difference between 5 minutes and 10 minutes per cable.

That looks very neat. Our house is 1930's -I'll get up and remove the insulation later on to have a look, but I dont think it'll have that broad escape route for a cable.In the loft there is a gap (in my house at least). You get to the top of the cavity so there isn't anything blocking it except for a small green flat bag of insulation. Just pull this out in advance.
This photo shows a black bag instead for example.

I guess as these photos show the cavity must come out at the attic so maybe it will be ok.This photo shows something similar. The top of these two walls is where your roof sits across, but doesn't block the top of the cavity.
It would be good to find out the hardware details and total cost. For comparison. I've found all the companies I've been in touch with to be very slow communicating and getting information.
I have to keep chasing them. It's the same with most tradesmen etc I've needed. Long gone are the days when they worked hard to get your custom. At least in my area.
1 thing my installer said that I didn't understand, was that using the newer H265 codec would lead to reduced functionality with some of the new camera features. Is this right? Is there any downside to using H265 with the Hikvision NVR?
