There is a product in decoration that many people may not pay much attention to, or they may want to modify it just because it is not good-looking enough and does not match the decoration style of their home.

It is the entrance door!

Nowadays, even rough houses are equipped with entry security doors. Due to cost considerations or neglect, many people do not decorate them. Go through this door.

But in fact, the anti-theft door at home plays an important role in security. The anti-theft door provided by the developer is not good in style, and the safety performance is also worrying.

If you want to change to a satisfactory security door, then you still have to pay attention to some aspects.

The thicker the security door, the better? That’s missing the point! The security of anti-theft doors depends crucially on the lock.

️Many people think that the thicker the anti-theft door, the better. In fact, the thickness of the steel plate 1.0 and 1.2, from daily safety considerations , there is not much difference. andLocks are what we need to focus on. Pay attention to these 4 points to ensure home security.

1. You must buy a C-level lock cylinder

Strictly speaking, a C-level lock cylinder It should be considered a super B-level lock cylinder. The national standard for anti-theft door lock cylinders is only divided into \”normal protection level\” and \”advanced protection level\”, which correspond to level A and level B. Due to the upgrade of anti-theft technology, there are super-level B lock cylinders, which we often call C. level.

Regular C-level lock cylinders have national safety certification. Class A lock cylinders have basically been eliminated and can only be used indoors. Class B lock cylinders are also not safe and cannot be used against the following cracking tools.

Nowadays, the C-class lock core generally has two rows of concave shapes and S-shapes on both sides, or double snakes inside and outside. In-mold milling groove structure. This structure is relatively complex, and its natural safety is greatly improved. The official test standard is that the tool cannot be opened for more than 270 minutes or even cannot be opened.

2. Selection of locking points

The function of the locking points is to prevent prying. How many locking points are suitable? In theory, it is getting better and better. In fact, 4 is enough.

For example, we often talk about the heaven and earth lock, which is the Class A anti-theft door with the highest anti-theft security level. The general locking point is at 12 o\’clock. As mentioned above, there are mainly 4 locking points, so normal locking points are enough. Don’t listen to the merchant’s lies about more than 20 locking points.

No matter how many lock points a security door has, they are all controlled by the same lock cylinder. That is to say, as long as the lock When the core is opened, the locking points will be opened.More than practicality.

3. Do you want to have cat eyes

The cat\’s eye is originally for safety reasons, so that you can observe the outdoor situation from indoors. In fact, this function is useless, the observation range is very small, and you cannot determine whether a larger range is safe.

In addition, the cat\’s eye poses a security risk. Thieves can use tools to enter through the cat\’s eye and open the door from the inside.

If you want to avoid this problem, you can only solve it like this:

1. If it is a mechanical lock, be sure to remember to lock it, otherwise it will be useless no matter how you pull the handle.

2. Install an electronic peephole. Although it is more expensive, it is very safe and can prevent peeping, automatic recording, and cannot be removed. It will send a reminder text message when someone is at the door, which is very useful. This way you can clearly see the situation at the door, which is very convenient.

4. Security level selection

Class A door + Class C lock = peace of mind

The anti-theft security level of anti-theft doors is divided into \”A\”, \”B\”, \”C\” and \”D\” according to the national standard \”There are 4 grades, which we can identify by the steel seal on the door frame. Among them, Grade A doors have the highest security, so Grade A doors + Grade C lock cylinder are the best combination.

As for brand selection, if you have enough budget, it is recommended to choose a big brand. The installation and after-sales service of security doors are very important. The installation masters of big brands will be relatively more professional and their services can be assured.
