  1. i'd go for an NVR rather than a PC. less to go wrong.

    Pelco cameras lost the PTZ funtions

    Hi mike, how are the data lines of the cameras wired? star, or daisy?

    So stupid...

    any chance of posting the video up?
  4. i'd go with a hybrid 8 channel NVR that has at least 4 analogue camera inputs. (so you can have 4 analogue cams and 4 IP cams) and then on the other building, either use four IP cameras, or four analogue cameras connected to an encoder, and then connect them to a wireless network bridge connected to the NVR.

    CCTV issues

    i assume the PTZs are wired in a combination of star and daisy, and the 5 PTZs not working are on a daisy spur which is has a fault. sounds like a big site, if you don't know what you're doing it'd probably be better to get someone in...
  6. i've used second hand cameras like this in the past that had a hole at the side, what i did was take the 'plug' from the hole at the back, and put it on the side, and then fill the hole at the back with a load of silicone.
  7. iknow, and i often wall mount DVRs too. but that doesn't change the fact that the connections are exposed! i'd like just a plain box on a wall, with a bunch of cables going into it, which are then terminated on the inside of the box! no connections visible from the outside! it shouldn't be about what's easier to install. the install takes what? a day or two? and then the system is in for years and years! i'd rather do a proper install and it take a little more effort, instead of doing a half arsed install and it looking cr@p for the years to come... but i find it a lot easier to make installs look neat when terminating cables into wall mounted boxes rather than desktop DVRs anyway.

  9. its about time that bloody DVR manufacturers made them in WALL MOUNTED BOXES! like intruder alarms and fire alarms and other such security equipment, especially the high end ones - having sometimes up to 40 cables terminating to the back of a 'set top box' is horrible!

    Need help with a massive project....

    first of all, where in the UK are you located? s this forum has a few engineers from the UK on it (including myself) secondly, you get what you pay for! it seems to me like you're going to be looking at at least £300 per wireless bridge! and with 15 cameras, that's not going to be cheap! don't forget though, you can get bridges that can do up to four cameras at a time, so as others have said, if you could get wired video connections from four cameras close together to a single point, you would save on the cost of three wireless bridges! stay away from that ebay stuff you posted. that'll cause you nothing but problems. by 'four channel' it means it has four different wireless ranges that can be selected on installation to avoid interference, it doesn't mean it can send four lots of video at once, plus, if you use these, you'll only be able to have 4 cameras wireless before you start getting interference from the others! how close are the cameras to each other? as it may be more cost effective to have the DVR out with the cameras in an IP rated box, and then all you'd need is one wireless network bridge which would be a far cheaper way of doing things! as others have said, a google maps screenshot with drawings of where the cameras will be would be useful!

    alternative PTZ!

    i acquired an old dennard PTZ CCTV housing, seems its about 20 years old, and decided i wanted to do something interesting with it. a few relays, lights, and a cheap lazer later... i ended up with this! k-cc54lTdCo i then decided to try my luck at getting into a few music festivals with it... its already been booked by two, earning me £150 from each :biggrin: it will have a 'control panel' that will be mounted about 20 meters from the camera its self, so that punters can move it and interact with it.
