could use a little help here guys.whenever i try to download a recorded video on my dvr,it always gives me an error that says "mpeg size - time point change (e206)" and the start point goes to the recorded top time.for example the recorded top time is 01-01-10 1200h.current time& date is 19-01-10 1700h,then i want to download a video starting from 05-01-10 0700h-0715h (15mins).it will display the error then change the start point to recorded top time which is 01-01-10 1200h.it just started when year 2010 steps in.tried restarting the unit,reseting all menus & initializing hdd but to no avail.anyone here having the same problem? sanyo dsr-m810 main v2.33 / sub v2.10 dvr utility software va-sw8000lite c1.3 windows xp sp3

i'm currently having problem with our matrix system.the monitor 1 keeps going back to camera 0 after a few minutes.we're using ge digiplex 4 KTD-440 512x32 setup.already double checked video and data lines,all seems ok.any ideas guys?

i read that rg59 can run a maximum of 750ft and rg6u at 1,000ft.how about for rg179u?and i case i use rg6u but need to run the cable more than a 1,000ft,do u just join them or is there a special equipment to be use to amplify the signal? i think i posted on the wrong thread.sorry

ok man.thanks for all the help.really appreciate it.learned alot from the infos you gave me.see you later.

the cam is placed in one corner of the elevator ceiling.the coax used is different because the centre core is not a single solid one.its a bundle of little thin wires.is that a flexible coax?the power is connected to the power outlet on top of the cab.i think your right that its getting interference whenever the elevator moves,i'll try to check that.the 2,000ft cam distance is inbuilding.i have browsed the site you gave and understand the use of utp balun.just one thing,whats the difference between active and passive balun?which is better,to use a utp or a coax for cable run or depends?if the run wont go more than a thousand ft,better to use coax,otherwise use utp instead?rg59 max length is 750ft while rg6 is 1000ft for video signal only or any is applicable.does it differ in length if i use a monochrome cam or a colored cam.were using hosiwell,psi highspeed or belden coax.depends on the supplier stock and also the purchasing dept as what will they give.i think its copper.what brand is good that you recommend?

sorry for the bunch of question man.i really appreciate your time in answering it.i'm just a begginer on a cctv system but have knowledge on the basic equipments.i just want to know other special equipments that are used.about the cable run for e.g. a 2,000ft rg6 cable from matrix to camera.both ends use female bnc(i don't know if thats what its called).how to do that if i'm going to use utp and balun?were using kalatel digiplex iv system.all are in rg6 cable connections.camera to vda,vda has 4 output.1 to the matrix,1 to dvr, others for quad/mux etc.also one problem with the cameras on an elevator.if the elevator is idle/not in use,the signal is clear but when it starts moving,i get a noise signal.

thanks for the replies.i'll just send the camera to the supplier for repair.

helo guys.i have kalatel ptz that goes black and white for a few seconds and stays like that.but when i initially mount it,it got color then a few seconds, goes black and white.i tested it out and guess its a camera problem.do you have any fix for this?another camera has control problem when i put it on other dome.like when put it as camera 1 on dome1,so when i choose cam 1 on the keypad i can control it.but when i put it as camera 2 on dome2(diffrent dome and location) and punch cam2 on keypad.it wont move.the video is ok.any help guys?

pro amp?proactive amplifier?where do i place it on the cable run?halfway?im thinking of using rg179 for connections from vda to matrix,dvr,quad,monitor ect. but not from camera to vda.all equipments are placed side by side so it wont be that long.i have idea about utp but what are baluns?

helo everyone!i'm keem from thailand.hope i could learn alot here.
