  1. Pin hole lenses are usually wide angle, so they spread a lot of light onto the CCD chip, white is obviously the highest heat signature, it is unlikely that this is the reason becasue the eye of the pinhole is so small I was hoping more for a refelctive surface, like a metal polished bench and a down light..I would say it is likely that the camera is just not good quality, is it a CMOS or CCD chip?

     

    Pin hole lenses do not spread lots of light onto CCD chip

    That why Pinhole cameras require much longer exposure times than conventional cameras because of the small aperture;


  2. I did it once using Telescope and color board camera

    ask mechanical shop to make adapter

    remove first lens on telescope and remove board lens from camera

    then it's easy to figure out

    hope its helps

     

    good luck

  3. Or you can use Voice Alert (http://www.voicealert.com/)

     

    6-Zone Monitoring Capability

    Customized Voice-Recordable Alerts

    All Weather, Wireless PIR Sensor Transmitters

    Multiple Beam Patterns for Optimal Detection

    Adjustable Mounting, Beam Sensitivity, and Delay Timer

    4 "C" Relays to Trigger Additional Devices

     

    When a zone is breached, a signal is sent up to 1000 ft (300 ft through walls) to the remote Base Unit which plays one of six user voice-recorded messages identifying the zone.

     

    Works nice with PTZ

     

    Voice Alert motion--->base unit trigger out-->DVR--->PTZ
