First use RU59 cable to connect your cam to monitor directly to see whether display well, then find reason.

increditable, but how about water proof ?

but wireless camera, you need power supply in camera terminal.

welcome to forum

Brand DVR ok but need more money.

I think you can updated software through Internet.

Might try adding an internal IP to the DynDNS domain to your hosts file.

Where i can find the software?

how much you want to pay for ?

When the waterproof camera show with mist inside, i wonder if can open and wipe out, or return them to supplier directly .

thank you. but we decide to give up because it is more than our budget to cintinue.

you can use monochrome CCD camera

It is important for us to knowunfeigned or counterfeit, we alway get quotation with low price.

First I confirm, almost the cost of cameras are much at one. Why ? As we known, standard camera contain chipset plus circuit board and locked shell. Therefore, the chipset is the most expensive, composed by CCD,DSP,CDS/AGC,V-Driver, EEPROM and EVR etc. Those are almost same price when suppliers purchase components, and other parts like resistance, capacitor, audion we can ignore. But why the sale price is different so far ?

1.locked shell. Use inferior popular cast die, you don’t find any problem after printing lacquer.

2.filter sheet. Use glassed laminated film, Why show bad image, Oh cheaper.

3.Power circuit. Make simple circuit to save, yawp largen.

4.Circuit board. Take out some parts like video driven, connect various lines. Whatever none use expensive lens in low-end.

But saving only several dollars in listed methods, not competitive ? OK, I have to make counterfeit SONY CCD camera as follows:

A. SONY High resolutions (480TV lines or more)

1.Low resolution imitate(Analysis: Actually these are from SONY, difference is that Low resolution one is 10 dollars cheaper)

2.SS-1 imitate (Analysis: SS-1_2603 plus ICX405AK CCD, you can’t find problem untill open crystalloid, If there show two crystalloids marked 28.375 and 17.7344, it’s unfeigned SONY CCD.)

3.High resolutions Sharp CCD imitate (The stitches of Sharp are same quantity as SONY ICX409AK, replace it directly)

B.Low resolutions(420TV lines)

1.Sharp CCD imitate

2.A1PRO CCD + 3142

3.A1PRO CCD+ NEXTCHIP

4.SONY CCD + NEXTCHIP

5.SONY CCD + M6

C.Low illumination(0.01lux/F1.2)

Super HAD CCD imitate Ex-view

How to calculate capacity of hard drive for 4ch real time DVR, the supplier suggest i purchase hard drive local, and it support 2x300GB driver in maximum, are those for one year last ? and how much for them ?

Last year we produced OEM 7 inch CRT rearview system for Europe company and reamin 40pcs instock, i know at present rearview system are TFT LCD monitors and wonder whether CRT log someone else need,

which vehicle i can sell to ?

I have started to rebuild them manually, but thanks for helping.

 

One other question I was expecting a timestamp on the images is this projected to the screen rather than stored in the file?

Hi, here i have Internet viewing software for Standalone DVR, which used for general MPEG4 encode, i can send it if necessary.

I am from China and specialized in CCTV system and consume electronics, hope hear from you.

We have produced 2.4GHz frequency wireless intercom door phone, they transmit analog signal in 4 different bands(2.414, 2.432, 2.450 and 2.468GHz), The faulty is that they are interfered each other when installing two or more in front door and back door at same time. and it transmit less than 40feet through walls.

I wonder if we use DSP(digital signal processor) replacing of analog processor to settle down interference, and which way make it more far under not changing power capacity(100mW in transmitter and receiver, it's our radio law).

Simple, it contain 12 bands in max from 900 to 1200MHz, 6 cameras ok without interference each other. Enlarge power capacity of transimitter and receiver to reach more if law permitting.
