would having it set to the wrong settings have caused any damage to anything? just that I had asked my boiler man to check the settings and he obviously hadn't done so - and I have had several issues with boiler cutting out, overheating and the amber light coming on and having to be pushed to...

thanks someone had mentioned to me that the default settings are for a gas boiler and I have oil - they said perhaps the following settings should be used min on/off time = 4 Boiler cycle rate = 3 The defaults are:- minimum on/off time = can be 1, 2, 3, 4 or 5 minutes - default is 1...

Hi Have just replaced a problematic Honeywell ST6400 with a sundial RF Pack 2 (ST9420C and DT92E) Other than obviously setting my chosen times is there any other settings I should be changing, or are all the defaults okay? such as cycle rate, min off/on time, optimum start, stop, dealyed...

no one said you had too - was just updating post to have correct information

actually if you check the brochure on the maplin website - it does state that model does have DCCS - i.e. ability to control PTZ or zoom lens cameras through BNC and not need additional rs485 control wires

yes will do - seems to be an AVC794 and an AVC794C - will email maplin and avtech to find out differences

only issue is that if cctvdirect supply hard disk it comes with 2 year warranty, but apparently only 1 year if not - which is odd as brochure actually says 3 years!

from the avtech website for that model:- DVR / Camera Communication System (DCCS) �� For PTZ or zoom-lens control cameras, there’s no need to additionally connect RS485 control wires for camera control because the control signals can be transferred by coaxial cables directly.

the maplin one is linked because they are only supplier I can find for the avtech range of IVS DVR's which feature push notifications for iPhones which interested me and also ability to control PTZ cameras via BNC rather than running a RS485 cable to control it

After lots and lots of research on google and reading advice from this and other forums Please comment on which one I should go for:- 1) Samsung SRD-450 - http://www.samsung-security.com/products/video-recording-and-management/dvr/4-channel/SRD-450.aspx 2) Avtech AVC794C -...

Thanks for info re wireless cameras etc - very handy to know I intend to only have email notifications for the inside camera which is protecting my home office - so nothing else should really set this off other than an intruder

yes I know that - but if I got an 8 way could 4 be BNC and 4 be wireless IP cameras?

Thanks Alarm 7. I meant adding more than 4 cameras - but 4 being BNC connected and any others being wireless IP cameras

Thank you - any idea who makes this device so I can look at website

Thanks After lots of research on the internet - it appears I am a bit limited as some suppliers will only sell direct to trade I have come up with the following options - all I hope would be better then the one I have just returned -...

Has anyone had any experience of the AVTECH range? they seem quite well spec'd and the iphone/ipad app looks quite professional

no it does not - but I did ask the company in advance and give list of my requirements - so was going on there expertise! or lack of it! - and that was what they recommended As I said didn't really know what to look for and that company was supposed to be good - I know now Surely the point...
