1. Factors affecting the image quality of trail camera.
The temperature of the environment

This is not taken seriously by many people. At minus 30 degrees, you will find that the reaction speed of the machine slows down and the battery life is shortened. This is the condition that all kinds of devices are close to the limit. It is possible to strike.

Various special environment.

In fact, digital cameras are also possible, but no one uses them that way. For example, when we take photos with a digital camera, we will try to use smooth light.

The brightness of the infrared LED

Animals like to appear at night, so the night is more important for trail camera. However, it is not a large number of LED lights, the effect is definitely good. Because too many LEDs will bring higher energy consumption, not necessarily bring better results.

How to take good quality photos, first needs a good trail camera, and then find the best shooting environment, of course a good trail camera can meet more than 90% of the needs, if you are a lazy person, then you need to choose a good brand.Well-known brands such as Campark  、Cuddeback  、Reconyx etc.

It is easy to take several good photos, but what we need is a bunch of good field photos, so pay attention to image quality.

2. The trigger speed calculation of the machine:

Generally, in view of the fact that the object enters the PIR sensing range and starts to calculate, when the machine takes the picture, we think it as the trigger speed of the machine.

Then why is there a difference between multiple PIRs and a single PIR?
The appearance of multiple PIRs is mainly to increase the PIR sensing angle.
Advantages: There is a start-up advantage when shooting at close range. For example, at a distance of 3 meters, a multi-PIR sensing angle of 100 degrees has a 20-degree advantage over a single PIR sensing angle. If your trigger speed is fast enough, there is no need to use multiple PIR technology. Because the current fast camera is within 0.5 seconds of trigger time, which is about a 0.5-meter stride, the camera's field of view can be completely covered.

Disadvantages: Increase in machine cost and power consumption. Because of its large sensing range, it leads to a lot of false aerial shots. Generally, machines with slow start-up quick freezing will use multi-PIR technology. If it is for a higher speed target, it is still a very good design.

3. PIR distance test.
In many trail cameras, the PIR sensing distance is rendered, and the ambient temperature and object temperature are both very important factors.
For example, when the temperature is low, if you walk by holding a large heat source, most machines feel that there is no problem.

4. PIR angle.
Is the PIR angle fixed? Definitely not.
A lot of publicity is 60 degrees, which is absolutely wrong. The PIR sensing angle and the camera's shooting angle are completely different concepts.
The angle of PIR becomes farther with the induction, it must be narrower.

The above is an analysis of the main features from the perspective of use, and then there are some things that are very convenient in use.

1. Password (protect the camera from being used by others)

2. Machine code (multiple machines can be directly identified on the camera according to the software machine number)

3. Take pictures regularly (when you put the camera at home, you go to work during the day and you are at home at night, you can set it to 9:00 - 18:00 in the morning, so that can take photos of this time period.)

All of the above are the advantages needed for trail cameras. In short, trail cameras are used by a special consumer group, fancy things are not practical here, so need to pay attention to some practical factors.
