I used glue gun to cover along any joints glass and around any possible places moisture can go in still getting moisture at night.

Awesome thanks, it was totally the dust just wiping outside of the lens cover did the trick problem resolved.

Okay i noticed that when i turn of IR assist light problem white spots go away completely why is that?

I have 2 more identical cameras and they all did this until i covered the gaps with electric tape and it stopped for good. However not this one. I think its same law as with car headlights if its sealed tight moisture don't build up inside if small opening then it will sweat like this in the morning.

I want to set up covert camera indoors need to mount on ceiling and have wire run along the wall or at a corner of the room idea is to have either tiny wire then paint over it or use flat wire whatever works and safe. I could use "flexible flat cable" (FFC tape)? They do make them completely flat, but can i put 12v trough it safely? Can i use thin bare (without shielding) cooper wire just bury into wall and paint over it, this wont be a fire hazard running 12 volts over it wont heart it up too much since CCTV cameras don't draw that much amps. Whats the minimal gauge (diameter) of cable to run like 10ft and still have decent signal? LED do use them and pretty sure they draw more power than cctv camera.

Looking for Analog to digital converter or a mini DVR that has option in firmware to setup upload to Network File System. Basically something like this but without a camera, not interested in storing footage on built in memory card, need to push video on network attached HDD.

I want to purchase four 8mp CCTV cameras Hikvision DS-2CD2185FWD-I(S) and i dont want to use NVR instead my goal is to use computer or even better a small network attached storage box like Synology. I have no idea how computer capture works... 1. Do i need some capture software so i need powerful video card and CPU or each cameras pushes a video to shared network drive? 2. What are computer system requirements for recording 8mp video from 4-6 cameras ~10FPS 3. How do i view all cameras in real time on my TV or computer?

You saying more expensive camera does H.265 encoding internally and push video file directly to NAS or FTP and you don't need powerful server computer? I only see option to record to PC hard drive from web interface live view. How should my final setup look like i install Hikvision iVMS-4200 software or similar on the server and it will pull stream from cameras encode them and save to HDD?

Actually LineIn option worked with powered microphone, but not with powerless microphone. Someone can explain the difference between this options LineIn and MicIn, manual is not clear for this. Also found this thread viewtopic.php?f=19&t=43452 ordered mic but it clearly states MicIn

I need a mic that dont use power as my camera is PoE and it has mic input/output. Cannot draw power from PoE its about 7 volts mic dont start on anyting below 12v. Is there powerless microphone solution? Only one i found is this but not available in US

Found this space calculator according to it i need about 1.2TB for 4 cameras per 24 hour highest settings 20FPS does it look about right? So i am guessing i get Seagate Surveillance HDD SkyHawk 8TB ST8000VX0022 - $270.

Tried to use microphone from my vice recorder nothing, but i been able to tune to some FM or AM radio channel that played trough the camera if i hold the end with my fingers. How you think that happened? Another thing there supposed to be LineIn and MicIn selection available according to videos i've seen but i only have LineIn option.

Approximately what hard drive size we are talking about and what CPU spec is there some online calculator i could use for the server specs? If H.264/265 encoding going on in the camera before signal is transmitted over Ethernet why cant data from camera be saved directly to the server HDD without need to use CPU to encode/decode if i don t need live view. I wish i could use motion detection, however i have worst possible environment for motion detection i tried in the past. Trees move, even if i exclude them from motion area sun reflects tree shadow in every direction during the day and shadow moves when wind blows on the trees, leafs and dust flying when wind is strong, cars drive by and headlights light the porch creating movement, insects fly into camera attracted by IR light, all this triggers recording frequently. With motion detection I had as much of events to go trough as if i had a 24/7 recorder, if i lower motion detection sensitivity then something happens and i don't even have recording for it half of the times. Perhaps if i use motion detection feature while recording 24/7 i will get entries in "Alarm Event" log with time so i can navigate trough them if something.

Okay i got camera today and installed Hikvision DS-2CD2185FWD-I(S) I have no SDCard installed so i have no idea of file size using their PC software i recorded 3840x2178 resolution using my computer its about 100MB per minute using H.264 variable bit rate. 1. So to record one day 24/7 i need about 1TB hard drive is that sounds about right? 2. I was going to use NAS, but they don't have much juice in terms of specs, my question why do i need powerful CPU since video is being encoded on the camera, is there way i can simply write stream i get from camera to hard drive without need to do extra decode/encode it again? I though camera can send video to NAS trough FTP (local network) however it there's no such feature in firmware.

In my Hikvision i only see upload images to FTP no video option available. Are there cameras that can just stream video to FTP (local network) nonstop?

So i assume any "passive" microphone as one in my phone headset should work?

Field of view gets smaller the less resolution i select? This has to do that cmos sensor uses less area to capture less resolution? I was under impression that it will just convert the video to smaller resolution inside camera than natively use less pixels on the sensor now there's no way to run 4k camera in 1920 resolution because its basically zooms in and quality gets lower

So what pinout i use for PoE camera T568A or T568B i have proper PoE 802.3AF switch (not one of the cheap ones that work in passive mode all the time).

Guess i will have to find out how this work when i get em.

I have stumbled upon this footage of Sony SNC-VB770 that comes at $6,000 - 10,000 price tag and i cannot believe that it has such night performance at 15 frames per second. fi8v3hXBWNA I need something with similar night performance but with price from this world (under $1000), any advice? Really this is for my car i want to set this up facing rear so i can spot a highway patrool trying to "pace" me before he succeed.

There's also Bosch Starlight which seems to be better but stuck at 2MP resolution just as Dohua and Hkvision nightfighters are junk for nigh use. Guess i be using regular 8mp IR cameras at for next few years.

Cameras installed inside and outside house kind of low and some within reach by evil neighbors who always trying to break them. I also had a problem with room mate that actually physically broken some of my bullet cameras and pulled the wires out others. Other time neighbor turning my (cheap bullet) camera away with a wooden stick So whats the best type of setup against tempering with equipment? I guess metal tubes for wires is one step how about actual cameras Bullet is out of the question too easy to break, dome perhaps? but domes can be also unscrewed and camera turned away. What type of setup they use in jails to prevent tempering?

Need to build reliable house grade IP camera setup power is a btch so i am going PoE. Now selecting actual IP cameras PoE enabled cameras cost more and less selection than regular IP cameras, considering a spitter Whats main difference between: 1. PoE camera with internal PoE splitter 2. PoE camera with external PoE splitter (built in) 3. Non PoE camera with 3rd party PoE splitter (~$10) Is there any difference in reliability or whatever?

I got 4 analog cameras 1 that has the longest wire is losing image at night time approx. 6pm - 6am, but works fine during the day, wire was cut in couple places then stripped and joined by hand and taped with electric tape, i wonder if that's the reason and soldering it together would fix it? I had this issue before, but now i have even longer wire i noticed that disconnecting power from all the cameras and then connecting only that camera having issue fixed it, but now as wire got even longer it does not work anymore. What causes this issue, does it have to do something with humidity change at night? Will using more expensive wire fix the issue? This screenshot was taken in the morning just before it started to work again.

Solved problem by plugging camera power from nearest to camera electric socket trough another DC adapter, so it was a analog cord issue, its cheap thin 50ft cable so no wonder. Here's link to product https://www.amazon.com/gp/product/B004I90734/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Actually i made 100ft wire from two of them.
