The IR cut have two types, one have only one filter, one other have two filters. Check your camera if it have two filters, if have two filters, do not support mixture light(IR and white light). Two filters function: During day time, one filter filtered the IR lights to assure good image quality and reproduction. During night time, one another filter filtered the white light to assure good b/w image. One filter camera only have day time filter.

Smart phone resolution is for TAKE PHOTOS, security camera resolution is for TAKE VIDEOS Taking video have to takes 25 to 30 images in one seconds, but Taking photo only one

Under 16:9 ratio, you set D1 resolution, under 4:3 ratio, you set 960H resolution " title="Applause" /> I don't understand what you mean by this. D1 resolution is 704 x 480, 4:3 ratio. if you display it in 16:9, the image of course will be stretched, 960H resolution is a kind of D1 resolution under 16:9 ratio, it's resolution is 960 x 480. But it have to display 16:9 ratio through 960H DVR.

Yes it is the difference between US and China version, China version without cable inside bracket, but US version have.

You need a NVR not DVR

ask the supplier send you a user manual

16:9 through 960H DVR, 4:3 through D1 DVR

Under 16:9 ratio, you set D1 resolution, under 4:3 ratio, you set 960H resolution " title="Applause" />

any photo showing? Try to turn your camera target to another place where around 10 meters far, checking if it is able focus correctly.

In analog, wide view and see number plate at 30 meter do not exist at the same time, except use PTZ camera, but it will over your budget.

IP camera or analog camera? Please check the TV format of your camera first, PAL or NTSC

How far from your 5 locations to your NVR? It's hard to storage 1080P resolution videos from remote, since each location requires around 4Mbps upload speed Internet for 1080P resolution.

I recommend you to use Hikvision or Dahua POE cameras, most of them under your budgets, you can select some bullet and turret type for installing. But besides cameras, you require a NVR or PC for storage, I recommend you to buy a NVR too for 7/24 recording.

Hi Fonix, Black clothes are showing purple color normally happened in CMOS sensor cameras. A CMOS sensor require a IR cut filter to correct the color. Cheap cameras always without or with low quality IR cut. And some cheap sensor, like cmos camera 420tvl use pixelpus pc1030 image sensor will meet the color probs even with a IR cut. I recommend you to use high resolution cmos cameras like 800tvl, 900tvl or 1000tvl, price is similar, also cheap enough, but image quality is wonderful.

Hello Fonix, Yes some of cheap cameras also with reputation and good quality, even with the same specs and chipset compare to brand cameras like Dahua. Brand cameras are expensive at the same specs as following reasons: 1. Brand cameras is able to provide local after sale service, so they are trustful. 2. Brand cameras often with their own patent design, cheap cameras often use common case where it can sourcing from market anywhere. 3. Brand cameras are well known, if you meet some probs, it's more convenience to ask for help. Maybe some people meet the same probs. 4. Brand cameras firmware upgrades is trustful, often can be download on their website. As said before, I recommend you to select HD systems (Analog HD or IP HD), here is the differences of these two HD solution: Analog HD: (AHD, HDCVI, HDTVI, HD-SDI), all of Analog HD are real time with no time lag. AHD: max. 1.3 MP resolution at present, use Nextchip solutions, many manufacturers do it, quite cheap, signal transmit 500Meters over coaxial cable. HDCVI: Designed by Dahua, max. 2.0MP resolution, mature technology, is able to transmit video, audio and RS485 signals in one coaxial cable, 500 Meters. cheap price. HDTVI: Designed by Hikvision, max 2.0MP resolution, but can't transmit audio, RS485 signals in one coaxial cable, 300 Meters, cheap price. HD-SDI: max. 2.0 MP resolution, the image quality is more sharp than AHD, HDCVI and HDTVI, but the signals limited to 100 Meters to 200 Meters by better coaxial cable. Price double than above. Pros: easy for installation, no time lag, cheap price. Cons: Resolution limited to 2.0 MP IP HD solution: Most of the IP cameras are real time preview from your pc or cellphone, but a little time lag. IP cameras is able to provide higher resolution like 2.0 MP, 3.0MP even more, and together with good software for multifunction settings, including video analytics, it's more intelligent. Pros: Higher resolution, full functional software. Cons: a little time lag, require some network knowledge for managing the system. Price are expensive than Analog HD system.
