  1. HI everybody.. my daughter's DVR got screwed up so she called the installer and the guy came and replaced with this.... no papers no documents........ charged her 800$

    To me it looks pretty obsolete Your opinion... Looking for Your judgement so I know how to handle the situation... sorry, the DVR front pic is pretty fuzzy...

    Thanx for help



  2. Anybody has come across these cameras? These give megapix pictures.... Will these cams work on a DVR (Dahua 1U.... ) or.. a HD SDI DVR is necessary to get most of these cams? At present I have regular Effio 700Tv line cams...


    Also a question about Pixim Seawolf cameras....My present cams do not work excellent with bright light.. etc.. Trying to get a better quality...

  3. Thanx.. the mention of those 2 lights escaped me.. Yes they will be a problem during night as the one on the left(mine) is on all the night... I have one dome to the right under the balcony pointing to my entrance door(one on the left) it gives a clear view of person at my door... but lately I discovered that my tenants(door on the right) are having some strange activities so I decided to keep an eye on the whole 2 door space and entrance into passage leading to the doors... That's my problem

  4. I guess the same problem here as I am having ... the light from behind the incoming person will block out the facial recognition as the light will overload the sensor and it will focus on the brighter part of the picture, in this case, the background... It might work only in case there is lots of light coming from the side of the door... otherwise it's money down the drain

  5. The entrance views..... (the doors on the right in the pic...dark brown doors) and the passage leading to the entrance... My option might be4 a cam(dome with 2-6-12 mm) between the doors under the cover???? The sun won't be directly into the cam so the subjects might be visible and recognizable ...







  6. Was considering it but... as the light comes from behind (usually it's after 3pm) and it is straight into my door, it might overload the sensor and , as it always is the case, the light from behind will render the persons face(etc) dark , so not recognizable.. am looking for something that might be installed under the roof overhang,over the doors, so there sun light does not interfere...



  7. I am looking for the entrance (main) door camera.. my cams that I have installed are 4-9mm... I need wide angle and great depth focusing as I need to have a closer look at the all width of the entrance stairs.... what optics should I be looking for?


  8. The cameras I have installed are these:








    Been cooperating with this manufacturer for 3 yrs now... have regular 450 Tv line cams and their DVR in my office & warehouse. Decided to go a bit higher and got Dahua 1U DVR and these cameras. Frankly, even with HDMI input and these cameras I am not that happy, as the difference in picture resolution is not that much striking different... that.s why I think maybe I have to be more precise with focusing. I have been using this to set up the cam video from the same manufacturer :




    Thanx for help!

  9. Lots of folks here talk about using welder's glass for cam focusing... Looks I need one.. I installed all my cams during day time, and they're all out of focus somehow... have to try focus using that glass.. Is it available in stores?


  10. This is the cable that I have used.. is it that bad????




    And the BNC connectors:




    And the power distribution box:




    My daughter's house was rigged by a CCTV security company... having checked the equipment used there I found mostly the same stuff(except for the Siamese cables)... the cams look pretty cheap etc..

    So is the stuff I have been using really crap, or , maybe I need something else..

    As a musician (I play guitar) so I am not a novice in cables... I have a lot for my pedals and mikes...


    This CCTV stuff fascinates me, along with some beefed up security for my house, I may get some new knowledge.

    Thanx for support.

    PS. MOntreal Qc here

  11. To continue the quality theme, here are the links to the cams that I bought from the manufacturer: What are the criteria that one has to follow in choice of cams?










    These are the cams that I have installed.

    My DVR is Dahua 1U .



  12. Anyway... another question... to continue the China theme... I have those cams that I bought from China along with the cables.. You know the regular type they sell.... 2 power + video... pretty thin cables , had problems connecting to my power box... the shielding is , looks. aluminum... My cams are connected via BNC connectors... The question... I read someting about those video baluns (active/passive). As I have good(I think ) cams; all 5 Effio 700Tv Lines with OSD etc and Dahua 1U DVR , I am not really happy with the picture quality... should there be something else betwee the cam /DVR connection to improve the video quality??


    Thanx for help
