Help with two translations: "Be vigilant..." & "Do not allow..."

Question

Hello, everyone! I am translating the following two English sentences into Spanish and was hoping that someone could either correct my mistakes or confirm that these translations are adequate.

The first sentence is:

1. Be aware of unusual or suspicious activity, personnel, smells or items.

I wanted to convey a sense of seriousness and urgency in "being aware" of these things, so I settled on this translation:

1. Esté vigilante ante las actividades, las personas, los olores y los objetos sospechosos.

Is this acceptable?

The next sentence is:

2. Do not allow trespassers onto the property.

I have written two options for #2 (I would like to keep the sentence in the active voice and not switch to the passive, ie "Trespassers are not allowed on the property"):

2a. No permite que los intrusos entren en la propiedad.

2b. No deje entrar a los intrusos en la propiedad.

Can someone help proofread/correct my sentences (or offer alternative translations) and tell me which, if any, are the best option?

Thank you so much in advance!

This forum is always so knowledgeable and helpful and I appreciate all of your input immensely.

Answer 1

Your sentences are fine and I would choose the first of the second two (2a) - it has a stronger nuance. Well done.
