Standard cables used to carry video signal for analog cameras are coaxial cables. These cables can’t be used to connect more than one camera. Means, individual cable needs to be laid for each camera.
What’s the difference between 4MP and 5MP?
5MP is only 25% more pixels than 4MP, which is telling, but even more to the point is that the linear resolution of a 5MP sensor is less than 12% greater than a 4MP. Put another way, a 9×9-pixel feature of an image on a 4MP sensor would only occupy about 10×10 pixels on a 5MP sensor.
How many MP is good for a security camera?
Majority of the time, our design currently suggests one or two cameras to be 4k resolution, capable of covering the most critical spots at locations to be secured, and other spots would be covered by good quality 2 megapixel resolution cameras.
Is 4MP enough for CCTV?
3MP, 4MP & 4K
HD1080P is high enough resolution to get great images if the cameras are zoomed in properly. 4MP halves your storage time but only gives you a 40% “improvement” in the image.Not only that but if you use wide-angle cameras you will rapidly get lower resolution images as you move away from the camera!
Is CAT5 or coax better for CCTV?
Long distance: There are some definite advantages. To begin with, CAT5 gives long distance video transmission capability. By using a CAT5 cable you can run CCTV colour video footage over 1000 metres.If a coaxial cable is used, you will still be required to run an extra cable for data transmission.
What is the maximum distance for CCTV cable?
The connection between the camera and the DVR is most often done using coaxial cable (75 ohms). Connectivity is done with BNC connectors (welded, crimped or screwed). In general, the maximum distance is 200 meters with KX6 coaxial cable and 500 meters with KX8 coaxial cable.
Can I use telephone cable for CCTV?
Yes, it could easily cause noise to be introduced into the phone line, as the video spectrum is quite wide. Turn the CCTV off, and see if the noise stops.
Which is better 2.8 mm or 4mm?
Although it has more clarity at a further distance, the 4mm lens shows a similar scene to the 2.8mm. The main difference is the reduced angle of view which gives the illusion that objects are closer to the camera. A 4mm lens is useful for detection & identification.
What is 3.6 mm lens?
A 3.6mm lens is designed to provide an approximate 78° field of view and is the perfect camera in most CCTV applications. Most people think that a 3.6mm lens won’t show a large field of view, but as you can see from the below images, there’s not a huge difference between a 2.8mm and 3.6mm lens.
How far can a 12mm lens see?
How far can my AvertX camera see?
| Camera and Focal Length | Recognition (60PPF) | Classification (40PPF) |
|---|---|---|
| @ 5mm (65° FOV) | 50ft | 75ft |
| @ 12mm (36° FOV) | 120ft | 180ft |
| HD438 / HD448 (8MP, 2.8mm lens) | ||
| 2.8mm (102° FOV) | 26ft | 40ft |
What are the different cables wires used for CCTV installation?

Can you cut and join CCTV cable?
The cables are color-coded, so strip them one at a time and splice each one individually to its corresponding wire on the opposite cable. You can solder them or crimp on small butt-type connectors, whichever you prefer. The wires are fine, so either option requires patience and a steady hand.
What is PoE Mode A?
Answer: There are two modes of PoE, A and B. Mode A delivers power on the data pairs of 100BASE-TX or 10BASE-T. Mode B delivers power on the spare pairs. PoE can also be used on 1000BASE-T Ethernet, in which case there are no spare pairs and all power is delivered using the phantom technique.
