able1 0 Posted May 22, 2013 (edited) Hello all, Having a problem with continued Camera location being Zapped when a storm goes by. Over the past couple of years have had to replace a single camera location with new units after a storm. About six(6) cameras at this point. There are 2 cameras in this building. The other camera had been zapped as well before the surge protection and ground rod was installed. Since then it just the one that has had the continued problem. The cameras are about 40 feet apart. The following are the other particulars. > It has always be the video side of the camera that has been hit. > Building is separated from main building by about 200' of underground PVC conduit. > Cable RG59 > Have installed at the building Ditek Surge Protector DTK-VSPBNCA. One at each camera. > Ground Rod installed within 50' and #12 Ground wire to Protector > Camera Powered locally with Wall Wart 12vdc with surge protection I know that this may be impossible but the main question is, what can be done to stop this from happening?? > Is there a better surge/spike protector?? > Would a second ground rod help?? > Would it make a difference if the camera was powered by 12vdc?? > Is there a way to determine the weak point of the system?? Thanks for any thoughts or suggestions that would be helpful. Les Edited May 25, 2013 by Guest Share this post Link to post Share on other sites
SectorSecurity 0 Posted May 23, 2013 Are you sure it is not an electrical surge which is taking out the camera? Have you tried plugging the camera into a surge protector on the power side as well as the video side? Share this post Link to post Share on other sites
able1 0 Posted May 25, 2013 Are you sure it is not an electrical surge which is taking out the camera? Have you tried plugging the camera into a surge protector on the power side as well as the video side? There is lies the paradox. Which came first the chicken or the egg. It seems that the video is getting hit since the power supply does not get zapped. BTW I typed wrongly before about the power source be 24vac. The cameras are powered by 12vdc wall warts. Thanks for the input. Les Share this post Link to post Share on other sites

able1 0 Posted May 25, 2013 try isolating camera from building Mount on wood or plastic block attached to building. The camera body is plastic so adding more most likely will not help. Thanks, Les Share this post Link to post Share on other sites
