  1. Hi , Having a cam at a gate that is 1000' RG59 cable with 2 splices Signal is too poor at the DVR and cable is underground. Any way to improve this ?
  2. Tks ! For a burial 1000' RG59 (inner 20AWG solid) with braid 95% , what would be approximately the resistance ? Possible ~41 ohms over 1000' ? Possible 10dB loss on 1000' ?
  3. Toss , When you said measuring the resistance to check the join , what reading should I expect and how to do it ? -Should I measure the DC resistance with a DVM ? -Or the impedance in AC , how ? -Connect a load at one end and measure at the other end ? Tks !
  4. 26VAC & 12VDC It's now connected to 26VAC
  5. Yes I know but somebody else did the wiring so damage is done. What option do I have ?
  6. Hi, Having a system with 2 16 channels NVR connected to a 10/100Mb router. To that router , I have a DVR 30 cam analog and a PC that runs a client software to see some cams pattern . Problem is there is a delay between the live action and the view in patterns . Sometime 30 sec sometimes 2 Minutes. Is the that the bandwidth is not enough ? Is the router 100Mb ok ? Any settings to lower bandwidth of the IP cam ? Or DVR ?
  7. Hi , Will try ! By the way , this picture is from night with IR on
  8. Hi , I'm having problem with 2 Hik cams (DS-2CD2132F) , image is orange (Cam # 12 & 15). I want to reset/restore them to their default values . Can I do it with iVMS or connecting to the IP cam or I need to physically unplug the power and press reset on the cam itself ? Tks !!!
  9. Hi , We have a few cams that are mounted to a big metallic frame (Outside gate) for 5 years now. Every 1 or 2 years , we got damaged cams because , i think , lighting. Opening the cams , we can see burned components inside. We use 12 VDC as power and baluns for video transmission. I don't know if damage is coming from power ( i doubt) or from the BNC . How can I protect the cams from this ? Tks for your help....
  10. Hi , I see more & more HD cams with coax cable . Are they compatible with older analog DVR ? Can the DVR resolution manage them ? Thanks !

    2MP Analog cam possible ??

    So it will work but with lower resolution ?

    2MP Analog cam possible ??

    The cam I have are DS-2CE16D5T-IT3-3.6MM from Hikvision.

    2MP Analog cam possible ??

    it will not work a all or max resolution will be from the DVR ?
  14. Hi , What is the maximum resolution for an analog CCTV camera ? Analog often refers to TVL resolution . Is it 540TVL in color ? or 960H ? I saw a few Analog HD 1080P or 720P , possible ? Tks
  15. Having DS-2CD2732 Is the latest revision 5.3.0 or 5.3.6 ? 5.3.6 seems to refer to DS-2CD27X2FWD-IZS and not DS-2CD27X2F-I Is it the same ? Compatible ?
  16. Hi , I installed 16 IP cams (DS-2CD2132F) on a Hikvision NVR (DS-7716NI). What does it mean when they say that it's hardcoded on the NVR and I cannot delete it from the NVR menu ? Thanks !
  17. Hi , Having some black "flickering spots" on the image. I think it's coming from the setting of the CAMS . As an example , every gray areas are having these spots. See picture... Cams are mix of Hikvision DS-2CD2132F , DS-2CD2112F , DS-2CD2712F & DS-2CD2732F Any idea ? Thanks !
  18. Hi , Using SADP utility , I m able to see some cams but I cannot connect to it with my password that I know is good. Is there any locked-out feature on these cams like after 3 attempts or something like that ? Tks ! Version of the CAM is V5.30
  19. With a pic , it's hard to see.... A video will be better to show... By looking the cam with the boat as an example , floor is gray but we see flickering black spots on it.
  20. Is this OK for this application ? TEW738APB
  21. Hi , Does a 1080P analog camera over RG59 compatible with an older DVR or resolution will not be optimal ? Thanks !
  22. Hi , Do I really need a box to connect a Blue emergency PULL station or I can just use a low voltage plate to make the connections ? It's for an access system using a 12/24VDC magnet. Camden CM-700 series Thanks !
  23. Hi , I have many IP CAMS connected to some NVRs. Is it a good thing to use relays from the NVR and use motion detection to activate a zone on a alarm panel ? No more of using IR detector in that case or it still better using IR . Thanks for your advise !
  24. It's not a fire wall. Just a regular wall. When saying low voltage , it's under what voltage ? 48 VDC ?
