1What are main differences between an imitated SONY CCD and an original SONY CCD?
Please see the picture below
2What are OSD, NR, WDR, ATR, HLC?
a, OSD: On-Screen Display. It is a menu showing all functions on the screen
b, NR: Noise Reduction. When it is night, NR can make the snow point on the screen less to make the image clear.
c, WDR: Wide Dynamic Range. When the camera faces the strong light area, WDR can make those very dark areas lighter and make those very light areas clear.
d, ATR: Adaptive Tone-curve Reproduction(Digital Wide Dynamic Range).
e, HLC: High Light Compensation.
3Sometimes the camera can't see very clearly at night like the picture left below but when I make the IR LED inactive, then the camera can see clearly. Why?
A: Reason: The waterproof cover reflected the light into the lens. Solution 1: Get rid of the waterproof cover; Solution 2: Make the front part of the waterproof cover become black like the picture below
4When the camera works under the daylight lamp, sometimes the color of the image becomes periodically. Why?
A: There is a auto shutter in every camera. The frequency of this shutter is something to do with the light in the camera's working environment. If the light is strong, the frequency will be high, which helps to reduce the exposure. And if the light is weak, the frequency will be low, which helps more lights to come into the CCD to make the image clear. From above, we can see that the frequency of the shutter is subjected to the light strength. Therefore, when the frequency of the daylight lamp matches that of the shutter well, the image will be normal. Otherwise, the color of the image will become periodicly.
5Why was there some water(water vapour) in the waterproof camera after working for a time?
6What is 4K Video Resolution?
4K is a new resolution standard designed for digital cinema and computer graphics. It has following advantages: higher image definition quality, more detailed picture, better fast-action and larger projection surface visibility.
4K format was named because it has 4000 pixels horizontal resolution approximately. Meanwhile, standard 1080p and 720p resolutions were named because of its vertical resolution. The new standard renders more than four times higher image definition than 1080p resolutions for example.

This format can't have the change in horizontal resolution, so changes in aspect are made through the vertical resolution. For example 4096×2304 is a frame size with aspect 16:9 and 4096×3072 — 4:3. The digital video resolutions examples:
Full Aperture 4k 4096 x 3112 12,746,752 pixels
Academy 4k 3656 x 2664 9,739,584 pixels
Digital Cinema 4k 4096 x 1714 7,020,544 pixels
Digital Cinema Aperture 4k 3996 x 2160 8,631,360 pixels
7Oqton Easy IP Solution?
Our Intelligent IP solution makes the installation easier and more secure.
Figure 1. Installation is a labor-intensive effort that requires an Ethernet cable and a power plug for the camera.
Figure 2. With the POE NVR, you only need an Ethernet cable to connect the IP camera and NVR.
Figure 3. With the WIFI NVR, you only need a wireless router to connect the IP camera and NVR.
Figure 4. With the PLC, you only plug in sockets of the same closed circuit to connect the IP camera and NVR.

Before: Several fixed cameras have to be installed to cover the entire store.
After: The whole shop is covered by one fisheye camera, reducing time and labor costs.
Oqton's Easy IP solution offers Wi-Fi Kits, and PoE NVRs for easy connection. The system features automatic IP address allocation, auto detection, auto connection, and easy access.
The automatic IP address allocation is convenient and saving time
Oqton's Easy IP cameras offer high compression efficiency and reduce the burden of transmission and storage on the IP surveillance system.
One month recording is compared H.265 IP camera with H.264 IP camera. The former reduce storage consumption by up to 1/3 compared to H.264 IP camera.
All Oqton Easy IP cameras support Oqton-connected P2P service, which enables remote access simply by using a smartphone to scan the supplied product QR code.
You can view the live video and recorded video files anytime and anywhere with P2P service.
8PLC Kits
What is PLC?
▲Power line communication (PLC) is a communication protocol that uses electrical wiring to simultaneously carry both data, and Alternating Current (AC) electric power transmission or electric power distribution.
▲ PLC package
PLC Kits: 4*plastic cameras + 1*NVR +1*mouse.
▲ Why choose PLC?
1.Easy to install
PLC Kits can be used after plugging in sockets, which is in the same closed circuit.
Low latency and work steadily..
3.Lower cost
Do not need network cable, just use existing ready-built power lines
▲ Application.
PLC KITS can be applied to home, office, store etc.
▲ PLC Kits. Power Line Communication. Super easy to install.
